*782 OPINION DAVIDSON, Chief Judge. Presently before the court in this patent dispute is defendant Parkhill Furnitureâs âMotion for Summary Judgment of Nonin-fringement or for a Markman Hearing.â After considering the motion, the court is of the opinion that the motion should be granted in part and denied in part. Brief Factual and Procedural Background The plaintiff, GFI, Inc., holds United States Patent No. 5, 064, 244 (â244 patent). This patent discloses a sectional sofa containing two reclining seats separated by a console. GFI claims that the defendants in this action, including Parkhill, are infringing the â244 patent by making, using, offering for sale and selling sectional sofas purportedly covered by the claims of the â244 patent. In its current motion for summary judgment, Parkhill argues that its models 8000 and 8960-11 do not infringe the â244 patent. Alternatively, Parkhill requests this court hold a Mark-man hearing to construe the language of claim 12 of the â244 patent. Herein, the court construes claim 12 and holds that Parkhillâs model 8000 does not infringe the â244 patent literally or under the doctrine of equivalents. Additionally, the court holds that Parkhillâs model 8960-II does not infringe claim 12 literally; however, material issues of genuine fact exist as to whether model 8960-11 infringes the â244 patent under the doctrine of equivalents. Standard of Review On a motion for summary judgment, the movant has the initial burden of showing the absence of a genuine issue of material fact. Celotex Corp. v. Catrett, 477 U.S. 317, 325 , 106 S.Ct. 2548, 2554 , 91 L.Ed.2d 265 (1986). Under Rule 56(e) of the Federal Rules of Civil Procedure, the burden then shifts to the non-movant to âgo beyond the pleadings and by.. .affidavits, or by the âdepositions, answers to interrogatories, and admissions on file,â designate âspecific facts showing that there is a genuine issue for trial.â â Celotex Corp., 477 U.S. at 324 , 106 S.Ct. 2548 . While all legitimate factual inferences must be viewed in the light most favorable to the non-movant, Rule 56(c) mandates the entry of summary judgment âagainst a party who fails to make a showing sufficient to establish the existence of an element essential to that partyâs case, and on which that party will bear the burden of proof at trial.â Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 255 , 106 S.Ct. 2505, 2513 , 91 L.Ed.2d 202 (1986); Celotex Corp., 477 U.S. at 322 , 106 S.Ct. 2548 . Before finding that no genuine issue for trial exists, the court must first be satisfied that no reasonable trier of fact could find for the non-movant. Matsushita Elec. Indus. v. Zenith Radio Corp., 475 U.S. 574, 587 , 106 S.Ct. 1348, 1356 , 89 L.Ed.2d 538 (1986). In patent infringement cases, summary judgment is appropriate only where the evidence is such that no reasonable jury could find two elements to be equivalent. Warner-Jenkinson Co. v. Hilton Davis Chem. Co., 520 U.S. 17, 39 , 117 S.Ct. 1040, 1053 , 137 L.Ed.2d 146 (1997). Discussion 1. Construction of Claim 12 In fulfilling its duty to construe the claims of the â244 patent, this court is free to consult âthe claim language, the written description portion of the specification, the prosecution history, [as well as] extrinsic evidence.â Gentry Gallery, Inc. v. Berkline Corp., 134 F.3d 1473, 1476 (Fed.Cir.1998); Markman v. Westview Instruments, Inc., 517 U.S. 370, 384 , 116 S.Ct. *783 1384, 1393, 134 L.Ed.2d 577 (1996). Claim 12 of the â244 patent provides in pertinent part that each reclining seat, having a backrest and seat cushion, must be âmovable between upright and reclined positions.â â244 patent; col. 5, 11. 10-11. The material question regarding the construction of this portion of claim 12 is whether it requires that the backrest itself be movable or whether a âseatâ can be movable between the upright position and the reclined position without the backrest necessarily moving. Claim 12 does not specifically state whether the seatâs backrest must move in order for the seat itself to be movable between the upright and the reclined positions. Likewise, the claim does not specifically define the terms âupright positionâ and âreclined position.â However, two of the drawings GFI submitted as part of the â244 patentâs specification shed light on how the terms âupright positionâ and âreclined positionâ are to be defined. In the specification section labeled âBrief Description of the Drawingsâ, GFI describes Figure 3A as representing the âuprightâ position and Figure 3C as illustrating the âreclinedâ position. â244 patent; col. 2. These figures clearly demonstrate that a seat cannot move between the âuprightâ position and the âreclinedâ position unless it has a movable backrest. Therefore, after careful consideration of the claim language as well as language and drawings contained in the specification, this court construes claim 12 as requiring that each seat contain a movable backrest. Additionally, Parkhill has requested that this court construe one element of claim 12, namely column 5 lines 22-27, as being a âmeans-plus-functionâ element and subject to a structural equivalence analysis in accordance with 35 U.S.C. § 112 (6) instead of a traditional doctrine of equivalents analysis. The court finds this element to be a means-plus-function element subject to 35 U.S.C. § 112 (6) and it will be analyzed in accordance with the dictates of that statute. 2. Infringement GFI concedes that, in accordance with this courtâs opinion of November 20, 1998 ( 27 F.Supp.2d 686 (N.D.Miss.1998)), neither Parkhillâs model 8000 nor Parkhillâs model 8960-11 literally infringe the â244 patent. GFI Opposition p. 7. Therefore, Parkhillâs motion for summary judgment as to literal infringement of the â244 patent by models 8000 and 8960-II is granted. It is axiomatic that an accused device does not infringe upon a patent unless every single claim limitation, or its equivalent, is present in the accused device. Malta v. Schulmerich Carillons, Inc., 952 F.2d 1320, 1325 (Fed.Cir.1991). The critical limitation in claim 12, as far as model 8000 goes, is that each seat must be âmovable between upright and reclined positions ...â â244 patent; col. 5, 11. 10-11. This limitation requires that the backrest portion of the seat be movable. Under the doctrine of equivalents, the essential inquiry is whether the accused product contains elements identical or equivalent to each claimed element (limitation) of the patented invention. War ner-Jenkinson, 520 U.S. at 40 , 117 S.Ct. 1040 ; Pennwalt Corp. v. Durand-Wayland, Inc., 833 F.2d 931, 939 (Fed.Cir.1987). As part of this inquiry, courts look to see if the differences between the products are merely insubstantial; where there is proof that only insubstantial differences exist between the products, infringement may be established. Insituform Techs., Inc. v. Cat Contracting, Inc., 99 F.3d 1098 , 1107 (Fed.Cir.1996). In determining the substantiality of the differences between the products, courts use the âfunction-way-resultâ test since if the products possess *784 similarity of function, way and result, there is little room for doubt that only insubstantial differences exist between the products. Hilton Davis Chem. Co. v. Warner-Jenkinson Co., Inc., 62 F.3d 1512, 1645 (Fed.Cir.1995). However, all three prongs (function, way and result) must be substantially identical or there is no infringement. Industrias Metalicas Marva v. Lausell, No. 96-1697, 1997 WL 557626 at *12 (D.P.R. Aug.28, 1997). In the case at bar, no genuine issue of material fact exists as to whether Parkhillâs model 8000 includes an equivalent element to the â244 patentâs claimed limitation of a âreclining seat ... movable between [the] upright and reclined positions.â â244 patent; col. 5, 11. 9-11. As already stated, this limitation requires that a seat have a movable backrest; Parkhillâs model 8000 undisputably does not have a movable backrest. So, does a genuine issue of material fact exist as to whether the model 8000âs nonmovable backrest performs substantially the same function, in substantially the same way, to achieve substantially the same result, as the movable backrest illustrated in the â244 patent? Neither the function, way nor result of the two backrests is the substantially the same. The backrests are structurally quite different and operate quite differently. In the device described in the â244 patent, the backrest tilts backward to allow the seat to move from the upright position to the reclined position. â244 patent; figs. 3A-3C. In sharp contrast, the model 8000âs backrest does not move at all, and the seat never moves into the reclined position. Therefore, neither the function the backrests perform, the way the backrests operate, nor the result obtained by the backrests is or can be substantially the same. The absence of a required claim limitation â a backrest capable of moving and allowing the seat to move into the reclined position- â creates a difference between the model 8000 and the â244 patented device that cannot be considered insubstantial. No reasonable jury could find the elements to be equivalent. Since it is undisputed that the backrest of Parkhillâs model 8000 is not movable and its seat cannot move into the reclined position, no genuine issue of material fact exists as to this element and Parkhill is entitled to judgment as a matter of law. However, Parkhill has not shown that it is entitled to judgment as a matter of law regarding the model 8960-11. The court finds that genuine issues of material fact exist, rendering summary disposition of this claim inappropriate. In any event, the court has the discretion to allow GFIâs claim of infringement (regarding Parkhillâs model 8960-11) under 35 U.S.C. § 112 (6) and the doctrine of equivalents to proceed to trial. Liberty Lobby, Inc., 477 U.S. at 255, 106 S.Ct. 2505 . A separate order in accordance with this opinion shall issue this day. ORDER Pursuant to an opinion issued today, it is hereby ORDERED that: (1) the âDefendant Parkhillâs Motion for Summary Judgment of Noninfringement or for a Marknan Hearingâ (docket entry 428-1) is GRANTED IN PART and DENIED IN PART; the motion is GRANTED as to (a) the Plaintiffs claim for literal infringement of United States Patent No. 5,064,244 (â244 patent) as to Parkhillâs models 8000 and 8960-11; (b) the Plaintiffs claim for infringement of the â244 patent under the doctrine of equivalents as to Park-hillâs model 8000. *785 (2) As to the remainder of the claims in this action, Parkhillâs motion is DENIED. (3) The Plaintiffs claim for literal infringement of the â244 patent is DISMISSED.
