Text: Applying Fifth Circuit law, we review the district court's decision to grant summary judgment de novo, applying the same standard as the district court. United States v. Caremark, Inc., 634 F.3d 808, 814 (5th Cir.2011). Summary judgment is appropriate if, in viewing the evidence in a light most favorable to the non-moving party, the court finds that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law. Fed.R.Civ.P. 56(a). Determining infringement requires two steps. First, the claim must be properly construed to determine its scope and meaning. Second, the claim as properly construed must be compared to the accused device or process. Carroll Touch, Inc. v. Electro Mech. Sys., Inc., 15 F.3d 1573, 1576 (Fed.Cir.1993) (citations omitted). The proper construction of a patent's claims is an issue of Federal Circuit law, and we review a district court's claim construction de novo. Cybor Corp. v. FAS Techs., Inc., 138 F.3d 1448, 1454-55 (Fed.Cir.1998) (en banc). To ascertain the scope and meaning of the asserted claims, we look to the words of the claims themselves, the specification, the prosecution history, and any relevant extrinsic evidence. Phillips v. AWH Corp., 415 F.3d 1303, 1315-17 (Fed.Cir.2005) (en banc). Infringement, whether literal or under the doctrine of equivalents, is a question of fact. Bai v. L & L Wings, Inc., 160 F.3d 1350, 1353 (Fed.Cir.1998). On appeal from a grant of summary judgment of non-infringement, we determine whether, after resolving reasonable factual inferences in favor of the patentee, the district court correctly concluded that no reasonable jury could find infringement. IMS Tech., Inc. v. Haas Automation, Inc., 206 F.3d 1422, 1429 (Fed.Cir.2000).
