    Plaintiffs Bombardier Recreational Products, Inc. and BRP U.S. Inc. (collectively 
“BRP”) brought this patent-infringement action against Arctic Cat Inc. and Arctic Cat Sales 
Inc. (collectively “Arctic Cat”).  BRP alleged that certain Arctic Cat snowmobiles (the 
“Accused Products”) infringed two of its patents related to snowmobile frames:
U.S. 
Patent  No.  7,213,669
(“the  ’669  Patent”)  and
U.S.  Patent  No.  7,124,847
(“the  ’847 
Patent”).  (Compl. ¶¶ 9-15, 30-36, Dec. 15, 2011, Docket No. 1; see
id. ¶ 9
, Ex. A (’847 
Patent); see
id. ¶ 30
, Ex. D (’669 Patent)).  The Court granted BRP summary judgment of 
infringement with respect to the ’847 Patent.  (Mem. Op. & Order at 31, Dec. 29, 2016, 
Docket No. 781.)  The issues for trial included whether Arctic Cat infringed the ’669 Patent, 

whether Arctic Cat’s infringement was willful, whether the asserted claims of BRP’s 
patents were invalid, and damages.  (See Verdict, Dec. 6, 2017, Docket No. 1071.) 
    After a three-week trial, the jury returned a verdict in Arctic Cat’s favor.  (J., Dec. 
6, 2017, Docket No. 1072.)  Although the jury found the ’669 Patent infringed, it found all 
asserted claims of both the ’669 and ’847 Patents invalid.  (Id.)  The jury did not make any 
findings related to damages or willfulness, consistent with the Court’s instructions.  (See 

Verdict.)                                                                 
    BRP  and  Arctic  Cat  filed  post-trial  motions  for  judgment  as  a  matter  of  law 
(“JMOL”) and motions for a new trial on various grounds.  (Defs.’ Mot. for JMOL, Dec. 
3, 2018, Docket No. 1094; Pls.’ Mot. for New Trial, Jan. 3, 2018, Docket No. 1099; Pls.’ 
Mot. for JMOL, Jan. 3, 2018, Docket No. 1102.)  In general, Arctic Cat seeks JMOL that 

it does not infringe the ’669 Patent, and BRP seeks JMOL that its patents are not invalid.  
Because the Court will find that sufficient evidence supported the jury’s findings and that 
a new trial is not warranted on any ground, the Court will deny the parties’ motions.

I.   STANDARD OF REVIEW                                                   
    While Federal Circuit law governs substantive patent law, regional circuit law 
governs a district court’s rulings on post-trial motions for JMOL and for a new trial.  See 
Finjan, Inc. v. Secure Computing Corp.,
626 F.3d 1197, 1202
(Fed. Cir. 2010). 
    A.   JMOL                                                            
    Under Rule 50 of the Federal Rules of Civil Procedure, the Court may resolve an 

issue as a matter of law if “a reasonable jury would not have a legally sufficient evidentiary 
basis to find for the party on that issue.”  “A motion for judgment as a matter of law should 
be granted when all the evidence points one way and is susceptible of no reasonable 
inferences sustaining the position of the nonmoving party.”  Hunt ex rel. Hunt v. Lincoln 
Cty. Mem’l Hosp.,
317 F.3d 891
, 893 (8th Cir. 2003) (quoting Neely v. Am. Family Mut. 
Ins. Co.,
123 F.3d 1127, 1129
(8th Cir. 1997)).  In making this determination, the Court 

must:                                                                     
         consider  the  evidence  in  the  light  most  favorable  to  the 
         prevailing party, assume that the jury resolved all conflicts of 
         evidence in favor of that party, assume as true all facts which 
         the  prevailing  party’s  evidence  tended  to  prove,  give  the 
         prevailing party the benefit of all favorable inferences which  
         may reasonably be drawn from the facts, and deny the motion,    
         if in light of the foregoing, reasonable jurors could differ as to 
         the conclusion that could be drawn from the evidence.           

Minneapolis Cmty. Dev. Agency v. Lake Calhoun Assocs.,
928 F.2d 299
, 301 (8th Cir. 1991) 
(quoting Atlas Pile Driving Co. v. Dicon Fin. Co.,
886 F.2d 986, 989
(8th Cir. 1989)).  
Because a Rule 50(b) motion constitutes a renewal of a Rule 50(a) motion made at the 
close of the evidence, a Rule 50(b) motion is limited to the issues raised in the Rule 50(a) 
motion.  Hinz v. Neuroscience, Inc.,
538 F.3d 979, 983-84
(8th Cir. 2008). 
    B.   New Trial                                                       
    The Court may grant a motion for a new trial “on all or some of the issues.”  Fed. 
R. Civ. P. 59(a)(1).  “A new trial is appropriate when the first trial, through a verdict against 
the weight of the evidence . . . or legal errors at trial, resulted in a miscarriage of justice.”  
Gray v. Bicknell,
86 F.3d 1472, 1480
(8th Cir. 1996).  “The authority to grant a new trial is 

within the discretion of the district court.”
Id.
The Court may grant a new trial where 
erroneous rulings “had a substantial influence on the jury’s verdict.”  Littleton v. McNeely,
562 F.3d 880, 888
(8th Cir. 2009) (quoting Harris v. Chand,
506 F.3d 1135, 1139
(8th Cir. 
2007)).  Only if the jury’s verdict is so against the great weight of the evidence that it 
constitutes a miscarriage of justice should a motion for a new trial be granted.  Ogden v. 
Wax Works, Inc.,
214 F.3d 999, 1010
(8th Cir. 2000).                      


II.  INFRINGEMENT OF THE ’669 PATENT                                      
    BRP argued at trial that Arctic Cat infringed claims 88 and 92-95 of the ’669 Patent.  
At the close of BRP’s case in chief, Arctic Cat moved for JMOL under Rule 50(a) that it 
did not infringe the ’669 Patent.  (Trial Tr. Vol. X at 2068:10-14, Jan. 2, 2018, Docket No. 
1087.)  The Court denied Arctic Cat’s motion.  (Id. at 2088:11-15.)  The jury found claims 
88 and 92-95 of the ’669 Patent infringed.  (Verdict at 1.)  Now, Arctic Cat renews under 
Rule 50(b) its motion for JMOL that it does not infringe.  Because BRP presented sufficient 

evidence from which the jury could have found by a preponderance of the evidence that 
Arctic Cat infringed claims 88 and 92-95 of the ’669 Patent, and because the jury’s verdict 
was not substantially influenced by any legal errors, the Court will deny Arctic Cat’s 
motion for JMOL.                                                          
    A.   Infringement Standard                                           
    “[W]hoever without authority makes, uses, offers to sell, or sells any patented 

invention, within the United States . . . during the term of the patent therefor, infringes the 
patent.”
35 U.S.C. § 271
(a).  To infringe, an accused product  must “contain[] every claim 
limitation or its equivalent.”  Medgraph, Inc. v. Medtronic, Inc.,
843 F.3d 942, 949
(Fed. 
Cir. 2016).                                                               
    B.   Sufficiency of Evidence                                         
    Arctic Cat’s primary noninfringement argument concerns the “seat position defined 

by the seat” limitation in claims 88 and 92-95 of the ’669 Patent.  There was sufficient 
evidence to support the jury’s finding that the Accused Products include a “seat position 
defined by the seat.”  The Court construed “seat position defined by the seat” to mean “a 
portion of the straddle type seat positioned beneath the center of weight distribution of a 

50th  percentile  North‐American  adult  male  weighing  78  kg  and  has  the  body  build 
illustrated in FIGS. 9A‐, 9B and 10 seated in a natural operating position.”  (Claim Const. 
Order at 35-36, Sept. 28, 2015, Docket No. 552.)  BRP presented evidence, including 
expert testimony, that the Accused Products meet this claim limitation as construed.  (See, 
e.g., Trial Tr. Vol. V at 960:23-961:2, 969:16-19, 973:18-974:6, Jan. 2, 2018, Docket No. 

1082; Trial Tr. Vol. VI at 1090:10-1091:18, Jan. 2, 2018, Docket No. 1083; Trial Tr. Vol. 
VII at 1501:2-1504:16, Jan. 2, 2018, Docket No. 1084.)  Arctic Cat’s argument that BRP 
never presented evidence of numerical measurements regarding the “seat position” (or the 
“center of weight distribution”) are unavailing, as neither the asserted claims of the ’669 
Patent, nor the Court’s construction of the “seat position” limitation require any numerical 
measurements – unlike, for example, the limitations in claims 92-95 of the ’669 Patent that 
recite numerical measurements for the location of the “steering position.”  (See ’699 Patent 

at 21:57-22:3.)  The Court will therefore deny Arctic Cat’s motion for JMOL on this 
ground.1                                                                  
    C.   Certificate of Correction                                       
    Arctic Cat also argues that it is entitled to JMOL of no infringement of the ’669 
Patent because a certificate of correction issued with respect to the ’669 Patent after this 
litigation started.  Arctic Cat’s position fails for two reasons.         

    First, Arctic Cat has waived this issue.  Arctic Cat made this argument in one of its 
motions in limine (which the Court denied before trial), but Arctic Cat omitted this 
argument from its Rule 50(a) motion.  (See Trial Tr. Vol. X at 2069:7-2073:2.)  Although 
Arctic Cat did not need to renew its evidentiary objection at trial, see Fed. R. Evid. 103(b), 
it was required to include this argument in its Rule 50(a) motion to preserve it for its Rule 

50(b) motion.  “Indisputably, if an argument is raised in support of a motion in limine, the 
motion is denied, and the argument is not restated at the appropriate time, the argument is 
not preserved under Rules 50 or 51.”  Repola v. Morbark Indus., Inc.,
934 F.2d 483
, 488 
(3d Cir. 1991); see Hinz,
538 F.3d at 983-84
.                             
    Second, Arctic Cat fails to engage the proper legal standard.  Arctic Cat correctly 

states that whether a patentee may assert uncorrected claims depends on whether the 

    1 The Court has considered Arctic Cat’s remaining arguments regarding the sufficiency of 
BRP’s evidence of infringement of the ’669 Patent (accounting for pitch attitude, using CAD 
drawings and photographs, using exemplar snowmobiles, and using the patent’s specification), 
and finds these arguments unpersuasive.                                   
uncorrected claims “omit[] a material limitation . . . not evident on the face of the patent,” 
H-W Tech., L.C. v. Overstock.com, Inc.,
758 F.3d 1329, 1335
(Fed. Cir. 2014).  But Arctic 

Cat argues that the certificate of correction simply changed the scope of the asserted claims, 
not that the alleged errors are omitted material limitations not evident on the face of the 
patent.2  Because the uncorrected claims of the ’669 Patent do not omit material limitations 
not evident on the patent’s face, the Court will deny Arctic Cat’s motion for JMOL on this 
ground.3                                                                  


III.  INVALIDITY                                                          

    At trial, Arctic Cat argued that the asserted claims of the ’669 and ’847 Patents are 
invalid on multiple grounds.  The jury found the asserted claims invalid on some grounds, 
but not invalid on others.  Arctic Cat and BRP cross-move for JMOL and a new trial on 
invalidity.  The Court will address the parties’ motions and arguments ground-by-ground 
for each patent.                                                          




    2 Arctic Cat appears to be confusing the standards for certificates of correction with 
reissued patents, which are distinct.  Compare
35 U.S.C. § 254
, with
id.
§ 252.  See generally Intel 
Corp. v. Negotiated Data Sols., Inc.,
703 F.3d 1360, 1364
(Fed. Cir. 2012) (discussing the 
differences between certificates of correction and reissued patents).     

    3 Arctic Cat also moves conditionally for a new trial on the issue of infringement of the 
’669 Patent.  For the same reasons that there was sufficient evidence to support the jury’s finding 
that Arctic Cat infringed claims 88 and 92-95 of the ’669 Patent, the jury’s finding was not against 
the great weight of the evidence.  A new trial on the issue of infringement of the ’669 Patent is not 
warranted.                                                                
    A.   Invalidity Standard                                             
    Issued patents are presumed valid.
35 U.S.C. § 282
.  An accused infringer asserting 

an invalidity defense must prove invalidity by clear and convincing evidence.  Microsoft 
Corp. v. i4i Ltd. P’ship,
564 U.S. 91, 95
(2011).                         
    B.   The ’669 Patent                                                 
    At trial, Arctic Cat argued that claim 88 is invalid for anticipation, and that claims 
88 and 92-95 are invalid for enablement, indefiniteness, anticipation, and obviousness.  
(See Jury Inst. Nos. 23-28, Dec. 6, 2017, Docket No. 1064.)  At the close of Arctic Cat’s 

case in chief, BRP moved for JMOL under Rule 50(a) that claims 88 and 92-95 of the ’669 
Patent are not invalid.  (Pls.’ Mot. for JMOL, Dec. 2, 2017, Docket No. 1043; Pls.’ Mot. 
for JMOL, Dec. 4, 2017, Docket No. 1058.)  The Court denied BRP’s motions.  (See 
Minute Entry, Dec. 4, 2017, Docket No. 1061; Minute Entry, Dec. 1065, Dec. 5, 2017, 
Docket No. 1065.)  The jury found claims 88 and 92-95 of the ’669 Patent invalid.  (Verdict 

at 2.)  Now, BRP renews its motion for JMOL under Rule 50(b) that claims 88 and 92-95 
of the ’669 Patent are not invalid.  Because Arctic Cat presented sufficient evidence from 
which the jury could have found by clear and convincing evidence that claims 88 and 92-
95 of the ’669 Patent are invalid, the Court will deny BRP’s motion.  The Court will also 
deny Arctic Cat’s motions related to invalidity of the ’669 Patent.       

         1.   Enablement                                                 
    The jury did not find that claims 88 and 92-95 are invalid for lack of enablement.  
Arctic Cat moves conditionally for a new trial in the event that the jury’s invalidity finding 
with respect to the ’669 Patent is later reversed or vacated, by this Court or on appeal.  The 
Court will deny Arctic Cat’s conditional motion on this ground because there was sufficient 
evidence to support the jury’s finding.                                   

    “To be enabling, the specification of a patent must teach those skilled in the art how 
to make and use the full scope of the claimed invention without undue experimentation.”  
MagSil Corp. v. Hitachi Glob. Storage Techs., Inc.,
687 F.3d 1377, 1380
(Fed. Cir. 2012) 
(quoting Genentech, Inc. v. Novo Nordisk, A/S,
108 F.3d 1361, 1365
(Fed. Cir. 1997)) 
(discussing
35 U.S.C. § 112
, ¶ 1).4                                       
    Arctic Cat had the burden of proving by clear and convincing evidence that the ’669 

Patent lacks a “sufficiently full and clear description of the claimed invention,” i.e., to 
enable “a person having ordinary skill in the art . . . to make and use the full scope of the 
claimed invention at the time the original patent application was filed,” and to do so without 
“undue experimentation.”  (Jury Inst. No. 23.)  Arctic Cat’s enablement argument centered 
on the “seat position defined by the seat” limitation and the alleged errors contained in the 

’669 Patent’s figures of an average male snowmobile rider.  Although Arctic Cat’s expert, 
Mr.  Warner,  testified  that  in  his  opinion  a  person  having  ordinary  skill  in  the  art 
(“PHOSITA”) would not know how to make and use the invention in light of those alleged 
errors, BRP’s expert, Dr. Raasch, testified to the contrary – that even in light of those 
alleged errors, a PHOSITA could make and use the invention by using a anthropomorphic 

dummy to approximate an average male rider to determine a “seat position.”  (Trial Tr. 
Vol. XII at 2680:6-2700:11, Jan. 2, 2018, Docket No. 1089 (Warner); Trial Tr. Vol. VI at 

    4 The pre-AIA versions of the Patent Act apply here.  See generally In re Nuvasive, Inc.,
842 F.3d 1376
, 1380 n.3, 1381 n.4 (Fed. Cir. 2016)                        
1071:15-1079:11 (Raasch).)  The jury was free to reject Mr. Warner’s testimony and credit 
Dr. Raasch’s testimony.  The Court will therefore deny Arctic Cat’s motion on this ground. 

         2.   Indefiniteness                                             
    The jury found that claims 88 and 92-95 of the ’669 Patent are invalid as indefinite.  
BRP moves for JMOL that those claims are not invalid for indefiniteness.  Because there 
was sufficient evidence from which the jury could have found by clear and convincing 
evidence that claims 88 and 92-95 of the ’669 Patent are indefinite, the Court will deny 
BRP’s motion for JMOL on this ground.                                     

    Patent claims must be definite, that is, they must “particularly point[] out and 
distinctly claim[] the subject matter which the applicant regards as his invention.”
35 
U.S.C. § 112
, ¶ 2.  “[A] patent is invalid for indefiniteness if its claims, read in light of the 
specification  delineating  the  patent,  and  the  prosecution  history,  fail  to  inform,  with 
reasonable certainty, those skilled in the art about the scope of the invention.”  Nautilus, 

Inc. v. Biosig Instruments, Inc.,
134 S. Ct. 2120, 2124
(2014).           
    Definiteness “is amenable to resolution by the jury where the issues are factual in 
nature.”  BJ Servs. Co. v. Halliburton Energy Servs., Inc.,
338 F.3d 1368, 1372
(Fed. Cir. 
2003).  For example, “factual determinations as to what one skilled in the art would have 
understood at the time” should be resolved by the jury.  Viva Healthcare Packaging USA

(holding that the accused infringer’s “extensive case on indefiniteness” did not warrant 
reversal of the district court’s decision on JMOL).  Indeed, as BRP admitted during this 
litigation, “[i]ndefiniteness challenges are highly fact intensive, and rarely the proper 
subject for [resolution by the court].”  (Pls.’ Opp. to Mot. for Summ. J. at 21, Apr. 25, 

2016, Docket No. 719 (citing TurboCare Div. of Demag Delaval Turbomachinery Corp. 
v. Gen. Elec. Co.,
264 F.3d 1111, 1118-19
(Fed. Cir. 2001)).)             
    Arctic Cat argued at trial that the limitation “seat position defined by the seat” 
rendered claims 88 and 92-95 of the ’669 Patent indefinite.  Specifically, the jury was 
required to resolve the factual dispute about whether a PHOSITA would understand, with 
reasonable certainty, the scope of the “seat position defined by the seat” limitation, in light 

of (1) several errors contained in the specification of the ’669 Patent, and (2) the phrase 
“natural operating position” contained in the Court’s claim construction. 
    Construction of “seat position defined by the seat” was quite challenging.5  On the 
one  hand,  the  patent  specification  explicitly  defines  “seat  position”  by  referencing  a 
“standard rider.”6  Yet the claim language itself states that the seat position is “defined by 

the seat” – an unambiguous reference to the seat, not a rider.  During prosecution, the 
phrase “defined by the seat” was added to overcome a rejection by the examiner who 
reasoned that defining “seat position” in relation to the body of an unspecified rider would 

    5 At claim construction, Arctic Cat did not formally seek invalidation for indefiniteness, so 
the Court did not make any findings or conclusions related to indefiniteness at that time.  (See 
Defs.’ Opening Claim Const. Br. at 28, 36, Dec. 19, 2014, Docket No. 448.) 

    6 The specification of the ’669 Patent states that “[t]he inventors of the present invention 
define the term ‘seat position’ to point out particular positions on the snowmobile that are adapted 
to function as the seat position for a standard rider,” that Figures “9A, 9B, and 10 illustrate the 
various dimensions of a standard rider,” and that “[t]he dimensions of the standard rider are a 
‘ruler’ by which the dimensions of the various embodiments of the snowmobile of the present 
invention are measured.”  (’669 Patent at 5:42-56.)                       
                                           (footnote continued on next page) 
make it “impossible to determine the scope of the claim.”  (Claim Const. Order at 32 (citing 
JA 2571, 2605-06, Mar. 9, 2015, Docket No. 469)7.)  After a thorough review of the 

intrinsic evidence, the Court construed “seat position defined by the seat” to reference both 
the seat and the rider, and to reference a “standard rider” as pointed out by the inventors 
during prosecution.  (Id. at 35-36.)  The Court – adopting BRP’s proposed construction – 
construed “seat position defined by the seat” as “a portion of the straddle-type seat,” 
thereby referencing the seat, “positioned beneath the center of weight distribution of a 50th 
percentile North-American adult male weighing 78 kg and has the body build illustrated in 

FIGS. 9A, 9B and 10 seated in a natural operating position,” thereby referencing a standard 
rider.  (Id.)                                                             
    At trial, Arctic Cat presented evidence that the figures of the standard rider in the 
’669 Patent contain numerous errors.8  For example, Figure 9A contains total arm-length 
measurements of 78.2 cm, 42.8 cm, and 87.3 cm; but the sums of the sub-dimensions that 

comprise the arm lengths equal 80.2 cm, 71.7 cm, and 67.4 cm.  (Defs.’ App. ¶ 36, Ex. 36 
(Trial Ex. D#1073) at 50, Feb. 19, 2018, Docket No. 1126.)  Also in Figure 9A, the total 
height measurements are listed as 184.3 cm, 152.7 cm, and 199.7 cm; but the sums of the 
sub-dimensions that comprise the heights equal 188.1 cm, 174.7 cm, and 160.8 cm.  (Id. at 

    7 Citations to “JA” are to the parties’ joint appendix filed during claim construction.  
(Docket Nos. 469-502.)                                                    

    8 During this litigation, two weeks after the claim-construction hearing, BRP sought a 
certificate of correction to correct “various mistranscriptions and omissions in the numbers 
representing dimensions in Figs. 9A, 9B, and 10.”  (Decl. of Niall A. MacLeod ¶ 3, Ex. 2, Oct. 16, 
2017, Docket No. 899.)  The Court excluded the Certificate of Correction from trial because BRP 
asserted only uncorrected claims of the ’669 Patent.  (Mem. Op. & Order at 8, Nov. 11, 2017, 
Docket No. 990.)                                                          
45.)  Arctic Cat presented expert testimony that the 42.8 cm total arm-length measurement 
is “wrong because it’s supposed to be between the other two” (78.2 cm and 87.3 cm), as is 

the 152.7 cm total height measurement (supposed to be between 184.3 cm and 199.7 cm).  
(Trial Tr. Vol. XII at 2686:20:-2691:9.)                                  
    There was also testimony that the differences between the total measurements and 
the  sum  of  the  corresponding  sub-dimensions  make  it  difficult  to  know  what  the 
dimensions of a standard rider are, and that there is no way to know which dimension (the 
total number or the sum of the sub-dimensions) is the correct one without conducting a 

“massive research project.”  (Id. at 2687:5-2688:11; see also Trial Tr. Vol. VI at 1125:9-
1126:21 (testimony of BRP’s expert that it would be a “difficult undertaking” to build an 
anthropomorphic dummy with the dimensions in Figures 9A, 9B, and 10 of the ’669 
Patent).)  And, there was testimony that the height measurement is a particularly important 
one in determining what a standard rider is.  (See Trial Tr. Vol. XII at 2685:13-2686:3.)  

Post-Nautilus, this evidence supports a finding that, because of the errors in the figures, a 
PHOSITA would not know what dimensions of a standard rider the inventors intended to 
incorporate into the definition of “seat position defined by the seat.”  See Dow Chem. Co. 
v. Nova Chem. Corp. (Canada),
803 F.3d 620, 634-35
(Fed. Cir. 2015) (holding that four 
methods of determining “slope of strain hardening coefficient” leading to different results 

rendered the claims invalid for indefiniteness); Teva Pharm. USA, Inc. v. Sandoz, Inc.,
789 
F.3d 1335, 1344-45
(Fed. Cir. 2015) (holding not clearly erroneous the district court’s 
factual findings that three possible definitions of “molecular weight” rendered the claims 
invalid for indefiniteness).                                              
    Arctic Cat also presented evidence that the Court’s construction of “seat position 
defined by the seat” – largely adopted from BRP’s proposed construction – rendered claims 

88 and 92-95 of the ’669 Patent indefinite because a PHOSITA would not understand, with 
reasonable certainty, what a “natural operating position” is.  For example, Joel Hallstrom, 
who worked in the snowmobile industry for almost forty years, testified that he has never 
heard the term “natural operating position” and that such a position does not exist for 
snowmobile riders.  (Trial Tr. Vol. IX at 2021:2-2023:21, Jan. 2, 2018, Docket No. 1086.)  
Mr. Warner, Arctic Cat’s technical expert, also testified that “there is no such thing as a 

natural  operating  position.”    (Trial  Tr.  Vol.  XII  at  2696:10-11.)    Moreover,  BRP’s 
witnesses  repeatedly  testified  that  a  “natural”  position  is  one  that  is  subjectively 
“comfortable” for the rider.  (Trial Tr. Vol. VI at  1068:13, 1069:1, 1069:4, 1081:4, 
1085:10, 1085:19, 1086:1; Trial Tr. Vol. XIV at 3210:12, Jan. 2, 2018, Docket No. 1091.)  
And “[c]omfort is different for every rider.”  (Trial Tr. Vol. VI at 1034:20; see also Trial 

Tr. Vol. XIII at 2945:24-2946:7, Jan. 2, 2018, Docket No. 1090.)  This evidence supports 
a finding that the phrase “natural operating position” does not have “an established, 
sufficiently objective meaning in the art.”  DDR Holdings, LLC v. Hotels.com, L.P.,
773 
F.3d 1245, 1260
(Fed. Cir. 2014).  Because sufficient evidence supports the jury’s finding 
that claims 88 and 92-95 of the ’669 Patent are invalid for indefiniteness, the Court will 

deny BRP’s motion for JMOL on this ground.                                
         3.   Anticipation                                               
    The jury found that claim 88 of the ’669 Patent is invalid for anticipation.  BRP 
moves for JMOL that claim 88 is not invalid for anticipation.  Because there was sufficient 
evidence from which the jury could have found by clear and convincing evidence that claim 
88 is anticipated, the Court will deny BRP’s motion for JMOL on this ground.

    There was sufficient evidence from which the jury could have found by clear and 
convincing  evidence  that  claim  88  is  anticipated  by  the  prior-art  Hetteen  prototype 

snowmobile.  First, there was sufficient evidence from which the jury could have found 
that the Hetteen prototype qualified as prior art.  For a third-party device to qualify as prior 
art for public-use purposes, the device must be “accessible to the public.”  Eolas Techs. 
Inc. v. Microsoft Corp.,

deliberately evade disclosure.”

.  “Even limited disclosure to those who are

    The Hetteen prototype was built by the late Edgar Hetteen, who also founded Arctic 
Cat.  (Trial Tr. Vol. X at 2237:17-2238:11; 2240:23-2241:3.)  Three witnesses testified 
about the prototype.  Roger Skime, a close friend and colleague of Mr. Hetteen, testified 
that he was shown and drove the prototype on Mr. Hetteen’s farm and alongside public 
roads during a visit to Mr. Hetteen’s farm in the 1980-82 timeframe.  (Id. at 2240:23-
2242:13, 2284:7-2286:17.)9  David Karpik testified that he too visited the Hetteen farm in 

the late 1990s, where he was shown the prototype.  (Trial Tr. Vol. XI at 2506:16-2507:25, 
2508:9-13, 2552:7-2553:16, Jan. 2, 2018, Docket No. 1088.)  David Guenther, the current 
owner of the prototype, testified similarly:  that he visited the Hetteen farm sometime in 
2000, where he was shown the prototype.  (Trial Tr. Vol. X at 2300-2314.)  Guenther 
bought the prototype from Mr. Hetteen in 2000. (Id. at 2301:4-2302:11.)10 

    In addition to these witnesses’ testimony, Arctic Cat presented the physical Hetteen 
prototype itself at trial.  (Trial Tr. Vol. XI at 2501:20-23; see also Parties’ Joint Ex. List, 
Dec. 5, 2017, Docket No. 1062 (admitting the Hetteen prototype into evidence as JTX-
002).)  The jury personally viewed the prototype and even asked a question during trial 


    9 The priority date for the ’669 Patent is November 26, 1999.  (Jury Inst. No. 26.) 

    10 Guenther’s conduct in 2000 is after the priority date of the ’669 Patent.  Irrespective of 
whether Guenther’s conduct can invalidate the ’669 Patent – which neither party has addressed –
Guenther’s testimony was probative of whether the Hetteen prototype invalidates the ’669 Patent 
and served to corroborate the testimony of Skime and Karpik.  See Transweb, LLC v. 3M 
Innovative Props. Co.,
812 F.3d 1295, 1301
(Fed. Cir. 2016) (“The corroborating evidence can 
include . . . testimonial evidence.”).                                    
about certain stickers on the prototype’s windshield and when those stickers were placed 
on it.  (Juror Question to Witness, Dec. 1, 2017, Docket No. 1055.)  Guenther testified that 

he put them on after he purchased the prototype.  (Trial Tr. Vol. X at 2304:11-23.) 
    BRP argues that the Hetteen prototype does not qualify as prior art as a matter of 
law because Arctic Cat relies solely on uncorroborated witness testimony.  BRP is correct 
that  a  single  interested  witness’s  uncorroborated  testimony  is  legally  insufficient  to 
establish an invalidating prior public use.  Transweb, LLC v. 3M Innovative Props. Co.,
812 F.3d 1295, 1301
(Fed. Cir. 2016); Finnigan Corp. v. ITC,
180 F.3d 1354
, 1366 (Fed. 

Cir. 1999).  But Arctic Cat did not rely on only uncorroborated testimony about the Hetteen 
prototype:  Arctic Cat presented the physical prototype itself to the jury, and Mr. Guenther 
testified that the prototype has remained substantially unchanged.  (Trial Tr. Vol. X at 
2303:6-2304:10.)  The physical prototype, together with the testimony of Skime, Karpik, 
and Guenther, constitutes sufficient evidence from which a reasonable jury could have 

found that the Hetteen prototype is prior art.  Finnigan, 180 F.3d at 1366 (“Mere testimony 
concerning invalidating activities is received with . . . skepticism because such activities 
are normally documented by tangible evidence such as devices . . . .” (emphasis added)). 
    Second, there was sufficient evidence from which the jury could have found that the 
Hetteen prototype includes each and every claim limitation of claim 88 of the ’669 Patent.  

BRP argues that no reasonable jury could have found that the Hetteen prototype engine 
was disposed in front of the seat.  But an image of the prototype clearly shows that a 
reasonable jury could have found that the engine of the Hetteen prototype is disposed in 
front of the seat.  (See Decl. of Niall A. MacLeod ¶ 7, Ex. F at 4 (Trial Ex. D#1569), Jan. 
3, 2018, Docket No. 1097.)  Moreover, Arctic Cat’s technical expert, Mr. Warner, opined 
that the prototype’s engine is disposed in front of the seat, explaining the difference 

between the prototype’s engine and transmission.  (Trial Tr. Vol. XI at 2593:25-2604:15.)  
Therefore, the jury had sufficient evidence from which to find that claim 88 of the ’669 
Patent is anticipated by the Hetteen prototype.11                         
         4.   Obviousness                                                
    While the jury did not find that claims 88 and 92-95 of the ’669 Patent were invalid 
for obviousness, Arctic Cat maintains that claims 88 and 92-95 of the ’669 Patent are 

invalid for obviousness as a matter of law, in light of the jury’s finding that claim 88 of the 
’669 Patent is invalid for anticipation.  Specifically, Arctic Cat argues that the Court should 
amend the judgment pursuant to Rule 59(e) to include an obviousness finding because 
“anticipation is the epitome of obviousness.”  Connell v. Sears, Roebuck & Co.,
722 F.2d 
1542, 1548
(Fed. Cir. 1983).  Alternatively, Arctic Cat seeks a new trial on obviousness. 

    A patent claim is invalid “if the differences between the claimed invention and the 
prior art are such that the claimed invention as a whole would have been obvious” to a 
PHOSITA.
35 U.S.C. § 103
; see KSR Int’l Co. v. Teleflex Inc.,
550 U.S. 398, 406
(2007); 
Graham v. John Deere Co. of Kansas City,
383 U.S. 1, 3
(1966).            
    “Rule 59(e) motions serve the limited function of correcting ‘manifest errors of law 

or fact or to present newly discovered evidence.’”  Innovative Home Health Care v. P.T.-


    11 Because the Court concludes that sufficient evidence supports a jury finding that the 
Hetteen prototype anticipates claim 88 of the ’669 Patent, the Court need not decide whether there 
was sufficient evidence that any other prior-art snowmobile anticipates claim 88. 
O.T. Assoc. of the Black Hills,
141 F.3d 1284
, 1286 (8th Cir. 1998).  The Court “has broad 
discretion  to  alter  or  amend  a  judgment  under  Rule  59(e).”    SFH,  Inc.  v.  Millard 
Refrigerated Servs., Inc.,
339 F.3d 738
, 746 (8th Cir. 2003).             

    The problem for Arctic Cat is that it argued that only claim 88 of the ’669 Patent is 
anticipated.  (See Jury Inst. Nos. 25-26.)  As such, the jury was instructed – without 
objection from Arctic Cat – that only claim 88 of the ’669 Patent was subject to the Court’s 
anticipation instruction.  Thus, because the jury did not find claims 92-95 of the ’669 Patent 
anticipated, Arctic Cat’s argument is unavailing.12                       

    Moreover, Arctic Cat is not entitled to a new trial on obviousness.  There was 
substantial testimony from both BRP and Arctic Cat about modifications to the prior-art 
snowmobiles that would enable them to meet the limitations of claims 92-95 of the ’669 
Patent, the effect that such modifications would have on the prior-art snowmobiles, and 
whether a PHOSITA would be motivated to make such modifications.  (E.g., Trial Tr. Vol. 

XII at 2790:14-2792:1, 2796:11-2798:7 (modifications); Trial Tr. Vol. XIV at 3204:7-
3205:10,  3184:3-3185:23  (modifications);  Trial  Tr.  Vol.  XIII  at  3127:17-3129:6 
(modifications); Trial Tr. Vol. XII at 2811:2-2812:7 (motivation); Trial Tr. Vol. XIII at 
3118:11-3119:3, 3121:13-3122:2, 3129:8-15 (motivation); Trial Tr. Vol. XIV at 3185:24-
3187:3 (motivation); see also Juror Question to Witness, Dec. 1, 2017, Docket No. 1056 

(asking about the effect of adjusting the steering position on a prior-art snowmobile).)  


    12 To the extent that Arctic Cat seeks to amend the judgment to include a finding that claim 
88 of the ’669 Patent is obvious in light of the jury’s finding that claim 88 is anticipated, it is 
unclear what purpose such an amended judgment would serve.                
Thus, the jury’s finding that claims 92-95 of the ’669 Patent are not invalid for obviousness 
was not against the great weight of the evidence.                         

    C.   The ’847 Patent                                                 
    At trial, Arctic Cat argued that claims 1 and 6 of the ’847 Patent are invalid for 
anticipation, and that claims 1 and 6-8 are invalid for obviousness.13  (See Jury Inst. Nos. 
25-28.)  At the close of Arctic Cat’s case in chief, BRP moved for JMOL under Rule 50(a) 
that claims 1 and 6-8 are not invalid.  (Pls.’ Mot. for JMOL, Dec. 4, 2017, Docket No. 
1058.)  The Court denied BRP’s motion.  (Minute Entry, Dec. 5, 2017, Docket No. 1065.)  

The jury found claims 1 and 6-8 of the ’847 Patent invalid.  (Verdict at 2.)  Now, BRP 
renews its motion for JMOL under Rule 50(b) that claims 1 and 6-8 of the ’847 Patent are 
not invalid.  Because Arctic Cat presented sufficient evidence from which the jury could 
have found by clear and convincing evidence that claims 1 and 6-8 of the ’847 Patent are 
invalid, the Court will deny BRP’s motion.                                

         1.   Anticipation                                               
    The jury found that claims 1 and 6 of the ’847 Patent are invalid for anticipation.  
There  was  sufficient  evidence  from  which  the  jury  could  have  found  by  clear  and 




    13 Arctic Cat also argued that claims 1 and 6-8 of the ’847 Patent are indefinite, but the jury 
did not find them indefinite.  Arctic Cat conditionally moves for a new trial on indefiniteness in 
the event that the jury’s invalidity finding with respect to the ’847 Patent is later reversed or 
vacated, by this Court or on appeal.  Arctic Cat’s argument here is that the term “pyramidal” is 
indefinite.  A new trial is not warranted.  There was sufficient evidence from which the jury could 
have found that Arctic Cat failed to prove by clear and convincing evidence that the term 
“pyramidal” is indefinite.  The Court will therefore deny Arctic Cat’s motion on this ground. 
convincing evidence that claims 1 and 6 of the ’847 Patent are anticipated by the T/S Mod 
snowmobile.                                                               

    First, there was sufficient evidence from which the jury could have found that the 
T/S  Mod  includes a  “pyramidal brace assembly.”    The  Court  already  determined  at 
summary judgment that the T/S Mod included a “pyramidal” assembly; the issue for trial 
was whether the T/S Mod met the “brace” limitation.  (Mem. Op. & Order (“Summ. J. 
Order”) at 21 & n.6, 26-28, Dec. 29, 2016, Docket No. 781; Mem. Op. & Order at 6, Nov. 
11, 2017, Docket No. 990.)  Arctic Cat presented the physical T/S Mod to the jury.  (See 

Parties’ Joint Ex. List.)  Also, Arctic Cat’s technical expert, David Karpik, testified that 
the T/S Mod pyramidal assembly is “a brace,” and explained that “anybody with common 
sense that would see that, if you put a tube between two points, that you are bracing 
something.”  (Trial Tr. Vol. XI at 2466:11-2467:10.)  And the T/S Mod’s creator, Steve 
Thorsen, testified that he called the legs of the pyramidal assembly “braces,” he agreed that 

they left the frame “more rigid” and “brace everything,” and he agreed that he could feel 
that they reduced “twist” when he grabbed the back of the T/S Mod.  (Id. at 2400:7-2402:3, 
2408:7-2410:2, 2411:7-11.)14                                              




    14 Although the Court held that Arctic Cat was not entitled to summary judgment that the 
T/S Mod pyramidal assembly “braced” the frame viewing Thorsen’s testimony in the light most 
favorable to BRP (Summ. J. Order at 26-28), at trial the jury was free to credit Thorsen’s testimony, 
Karpik’s expert testimony, and the jury’s personal inspection of the T/S Mod. 

                                           (footnote continued on next page) 
    Second, there was sufficient evidence from which the jury could have found that the 
T/S Mod includes an “apex.”15  The Court construed “apex” to mean “the uppermost part 

of the pyramidal brace assembly.”  (Claim Const. Order at 15.)  Suffice it to say that, given 
that the jury had a sufficient basis to find that the T/S Mod included a pyramidal brace 
assembly, it also had a sufficient basis to find that such assembly included an “uppermost 
part.”  BRP’s argument that the T/S Mod lacks an “apex” because one of the four tubes of 
the T/S Mod’s assembly is welded to the side of another tube rather than at the steering 
bracket was an argument for the jury.                                     

    Third, there was sufficient evidence from which the jury could have found that the 
“upper column” limitation was met.16  For example, there was evidence, drawn from the 
prosecution history of the ’847 Patent, that the “upper column” limitation was admitted 
prior art, (Trial Tr. Vol. I at 195:3-196:24, Jan. 2, 2018, Docket No. 1078; Trial Tr. Vol. 
XI at 2425:16-21, 2468:11-2470:16); that a prior-art snowmobile contained an upper 

column, (Defs.’ App. ¶ 29, Ex. 29 (Trial Ex. D#964); Trial Tr. Vol. XI at 2470:1-2473:4); 
and that upper columns were common snowmobile components before the subject matter 
of the ’847 Patent was invented (Trial Tr. Vol. XI at 2502:14-2505:10).   




    15 The “apex” limitation appears in claim 6 of the ’847 Patent, but not in claim 1. 

    16 The “upper column” limitation appears in claims 7 and 8 of the ’847 Patent, but not in 
claims 1 or 6.  Arctic Cat did not argue that claim 7 or 8 is anticipated.  (See Jury Inst. No. 25-26.)  
Nevertheless, the Court will address BRP’s argument, as the “upper column” limitation is relevant 
to the jury’s obviousness finding.                                        
                                           (footnote continued on next page) 
    Fourth, there was sufficient evidence from which the jury could have found that the 
T/S Mod is in fact a “snowmobile” with “skis.”17  Photographs of the T/S Mod clearly 

show that the jury was free to so find.  (Defs.’ App.  ¶ 6, Ex. 6 (Trial Ex. D#269).)  BRP’s 
arguments that the T/S Mod was an ‘oval ice racer,’ and not a ‘snowmobile,’ were for the 
jury.18                                                                   
         2.   Obviousness                                                
    The jury found by clear and convincing evidence that claims 1 and 6-8 of the ’847 
Patent are invalid for obviousness.  BRP seeks a new trial on obviousness because of 

alleged errors in both the jury instructions and the special-verdict form. 



    17 In its post-trial briefing, BRP implies that the Court shirked its claim-construction 
responsibility with respect to the “snowmobile” and “skis” limitations.  (Defs.’ Mem. at 33 & n.5, 
Jan. 3, 2018, Docket No. 1104.)  BRP’s complaint is that the Court declined to construe those 
terms at summary  judgment –  almost two  years after  claim construction.  (Id.)   At  claim 
construction, the parties requested that the Court construe nearly 20 terms in the ’847 Patent and 
11 terms in the ’669 Patent.  (Joint Claim Const. Statement, Ex. B, Sept. 22, 2014, Docket No. 
360.)  Although “skis” made the parties’ initial list, “snowmobile” did not.  (Id.)  The Court ordered 
the parties to limit their briefing and argument to “ten representative claim terms, phrases or 
clauses.”  (Order, Sept. 25, 2014, Docket No. 362; see, e.g., N.D. Ill. LPR 4.1(b) (limiting by local 
patent rule the number of claim terms the court will construe to ten).)  Neither “snowmobile” nor 
“skis” was on the parties’ revised list of ten terms requiring construction.  (Joint Claim Const. 
Statement, Nov. 11, 2014, Docket No. 432.)  BRP could have insisted to Arctic Cat during the 
meet-and-confer process that it would seek construction of “snowmobile” and “skis” and could 
have made necessary concessions to effectuate that result.  But BRP did not.  The Court recognizes 
that it may be difficult to predict how failing to seek construction of a certain claim term will affect 
the ultimate outcome of a patent-infringement action.  See, e.g., Arctic Cat, Inc. v. Bombardier 
Recreational Prods. Inc., No. 12-2692,
2018 WL 654218
, at *4 (D. Minn. Jan. 2, 2018) (granting 
the accused infringer summary judgment of noninfringement after the parties failed to seek 
construction of a key claim term).                                        

    18 Because the Court finds that sufficient evidence supports a jury finding that the T/S Mod 
anticipates claims 1 and 6 of the ’847 patent, the Court need not decide whether there was sufficient 
evidence that any other prior-art snowmobile anticipates claims 1 and 6.  
              a.   Jury Instructions                                     
    Jury instructions “viewed on the whole,” should “fairly and adequately represent 

the evidence and applicable law in light of the issues presented to the jury in a particular 
case.”  Klisch v. Meritcare Med. Grp., Inc.,
134 F.3d 1356, 1358
(8th Cir. 1998).  How the 
Court crafts jury instructions is within the Court’s sound discretion.  Reed v. Malone’s 
Mech., Inc.,
765 F.3d 900, 907
(8th Cir. 2014).  Challenges to jury instructions must be 
reviewed in the context of the overall instructions, not just a single word or sentence.  See 
Therasense, Inc. v. Becton, Dickinson & Co.,
593 F.3d 1325, 1331
(Fed. Cir. 2010).  In 

crafting jury instructions, “[t]he district judge need not use any particular form of words or 
sequence of ideas so long as the charge as a whole conveys to the jury a clear and correct 
understanding of the applicable substantive law without confusing or misleading them.”  
9C Arthur R. Miller, Fed. Prac. & Proc. Civ. § 2556 (3d ed. 2017) (footnote omitted).  “It 
is axiomatic that the trial court should charge the jury in plain language.  It should not use 

technical or obscure legal phrases if the legal rule can be stated in less formal words.”  Id.  
An error in jury instructions justifies a new trial “only if the error ‘misled the jury or had a 
probable effect on its verdict.’”  Hallmark Cards, Inc. v. Murley,
703 F.3d 456, 460
(8th 
Cir. 2013) (quoting E.I. du Pont de Nemours & Co. v. Berkley & Co.,
620 F.2d 1247, 1257
(8th Cir. 1980)).                                                         
    Here, the Court instructed the jury that it “should” consider objective indicia of non-
obviousness in making its obviousness determinations.  (Jury Inst. Nos. 27-28.)19  BRP 

contends that the jury should have been instructed that it “must” consider objective indicia 
of non-obviousness because such considerations are mandatory.             
    Much ink has been spilt over whether “‘should’ always has a permissive rather than 
mandatory, meaning.”  Bord v. Rubin, No. 97-6401,
1998 WL 420777
, at *4 (S.D.N.Y. 
July 27, 1998).  Quite simply, context matters.  Id.; see Montgomery, 462 F.3d at 1070 
(“[U]se of the word ‘should’ is not unambiguous and must be read in context.”).  BRP’s 

argument – that “should” is permissive – has more traction in the context of statutes and 
contracts:  words written by lawyers, argued over by lawyers, and interpreted by lawyers.  
See McDonnell Douglas Corp. v. Islamic Republic of Iran,
758 F.2d 341, 347
(8th Cir. 
1985).  But see United States v. Montgomery,
462 F.3d 1067, 1069-70
(9th Cir. 2006) 
(holding that the word “should” in a prior Ninth Circuit opinion described a mandatory act, 

not a  permissive one).  Here, however, in  the context of jury  instructions, “should” 
sufficiently conveyed to the members of the jury (none of whom were lawyers) the 


    19 The Court’s use of “should” in its instruction on objective indicia of non-obviousness 
was consistent with both the 2016 version of the Federal Circuit Bar Association’s Model Patent 
Jury Instructions, see Fed. Cir. Bar Ass’n, Model Patent Jury Instructions 50 (2016) (“In making 
these assessments,  you  should  take into account any objective evidence (sometimes called 
‘secondary  considerations’)  that  may  shed  light  on  the  obviousness  or  not  of  the  claimed 
invention, . . .” (emphasis added)), and the January 2018 version of the Northern District of 
California’s Model Patent Jury Instructions, see U.S. Dist. Ct., N.D. Cal, Model Patent Jury 
Instructions 37 (2018) (“Finally, you should consider any of the following factors that you find 
have been shown by the evidence . . . . Although you should consider any evidence of these 
factors, the relevance and importance of any of them to your decision on whether the claimed 
invention would have been obvious is up to you.” (emphases added)).

purportedly  mandatory  nature  of  their  consideration  of  objective  indicia  of  non-
obviousness.  Indeed, the Eighth Circuit has held that it is not an abuse of discretion to 

instruct a jury that it “should” consider something, when the underlying substantive law 
suggests that that something “must” be considered.  Klisch,
134 F.3d at 1358-59
.20   
    BRP does not cite to any authority holding that it is legal error (and not harmless) 
to instruct a jury that it “should” consider something, rather than that it “must.”  Rather, 
all of the Federal Circuit authority that BRP cites concerns a court’s finding of obviousness 
or non-obviousness, not a jury’s.21                                       

    Even if it was error for the Court to use “should” rather than “must,” such error was 
harmless – it neither misled the jury nor had a probable effect on the verdict.  See Hallmark 
Cards, Inc, 703 F.3d at 460.  First, the word “should” did not mislead the jury, given its 
use in context.  Second, using “should” instead of “must” did not have a probable effect on 


    20 Had the Court used “may” instead of “should,” BRP might be entitled to a new trial.  Cf. 
Risdal v. Halford,
209 F.3d 1071, 1071-72
(8th Cir. 2000) (holding in a § 1983 case that it was 
legal error to instruct jury that it “may” award nominal damages if the jury found a constitutional 
violation, instead of that it “must”).

determinations at summary judgment, after a bench trial, or at JMOL.  Millennium Pharm., Inc. v.

the outcome.  At best for BRP, “the term ‘should’ . . . connote[d] a strong suggestion,” 
Montgomery,
462  F.3d  at  1069
,  meaning  that  it  was  highly  probable  that  the  jury 
considered objective indicia of non-obviousness.22                        

              b.   Special-Verdict Form                                  
    The use, form, and contents of a special-verdict form are within the trial court’s 
discretion.  See SEC v. Capital Sols. Monthly Income Fund, LP,
818 F.3d 346, 354
(8th Cir. 
2016).  As long as the special-verdict form “accurately, adequately, and clearly state[s] the 
relevant issues” to be decided, courts will be deemed to have properly exercised their 

discretion.  Chlopek v. Fed. Ins. Co.,
499 F.3d 692, 701
(7th Cir. 2007). 
    BRP proposed using a special-verdict form that would have asked the jury (1) 
whether each individual claim was invalid, (2) if so, the ground(s) for each claim found 
invalid, and (3) the particular prior art used for each ground of invalidity.  (Pls.’ Proposed 
Special Verdict Form at 2-4, Oct. 16, 2017, Docket No. 884.)  The Court, however, 

favoring simplicity, used a form that asked simply whether all the asserted claims of each 
patent were invalid, and on what grounds.  (See Verdict at 2-3.)          
    BRP argues that it is entitled to a new trial because the special-verdict form asked 
whether the jury found “all” the asserted claims invalid, rather than on a claim-by-claim 



    22 In fact, the jury very likely took objective indicia of non-obviousness into account in 
making its obviousness determinations.  The jury found claim 88 of the ’669 Patent anticipated, 
but did not find claims 92-95 of the ’669 Patent obvious – and those claims depend from claim 88.  
That the jury found independent claim 88 anticipated and dependent claims 92-95 not obvious 
strongly suggests both that the jury considered objective indicia of non-obviousness.  The logical 
inference, then, is that with respect to the ’847 Patent, the jury there too considered objective 
indicia of non-obviousness, but found claims 1 and 6-8 of the ’847 Patent obvious nevertheless. 
basis.  BRP argues that the form was prejudicial because the jury would give “less scrutiny 
and/or weight” to the dependent claims than to the independent claims.  (Pls.’ Mem. at 17, 

Jan. 3, 2018, Docket No. 1101.)  First, BRP cites no authority supporting its argument that 
a simpler form like the one the Court used caused BRP sufficient prejudice to justify a new 
trial, or frankly any prejudice at all.  Second, to the extent that any such prejudice occurred 
as a result of the structure of the special-verdict form, the Court’s instructions eliminated 
(or at least substantially mitigated) any such prejudice.  (See Jury Inst. No. 23 (“Each claim 
is effectively treated as if it were a separate patent.”); Jury Inst. No. 27 (“In determining 

whether the claimed invention was obvious, you must consider each claim separately.” 
(emphasis  added));  see  also  Jury  Inst.  No.  15  (describing  the  difference  between 
independent and dependent claims).)  BRP is not entitled to a new trial on obviousness. 

IV.  DAMAGES AND WILLFULNESS                                              
    The jury did not make any findings related to damages or willfulness, consistent 
with the instructions on the special-verdict form.  (See Verdict at 3.)  Because the Court’s 
rulings on the parties’ motions does not result in a finding of liability by Arctic Cat for 

infringement of a valid patent claim, a new trial  on damages and willfulness is not 
warranted.  If after any further proceedings, however, there is a finding of liability by Arctic 
Cat for infringement of a valid patent claim, then BRP would be entitled to a new trial on 
damages and willfulness.
