Opinion

ORDER

ZILLY, District Judge.

I. INTRODUCTION

This matter comes before the Court pursuant to Markman v. Westview Instruments, Inc., 52 F.3d 967 (Fed.Cir.1995), aff'd, 517 U.S. 370, 116 S.Ct. 1384, 134 L.Ed.2d 577 (1996), to construe various terms of the patents at issue in this case. The Court held a hearing on December 12, 2005, and asked for supplemental briefing on certain terms. The Court has reviewed all of the briefing, the records and files herein, and now enters the following Order.

II. DISCUSSION

A. Background

On April 29, 2004, Esquel Enterprises Ltd. filed a complaint for declaratory judgment and other relief against TAL Apparel Limited and Taltech Limited (collectively “Taltech”) in this Court. Compl., docket no. 1. On April 30, 2004, Taltech Limited filed a complaint alleging patent infringement against Esquel Apparel Inc. and Es-quel Enterprises Ltd. (collectively “Esqu-el”) in the Eastern District of Texas, Case No. 2-04CV-179. On July 27, 2005, the Eastern District of Texas transferred its case to the Western District of Washington, Case No. C05-1318TSZ. On October 18, 2005, pursuant to a stipulation of the parties, the Court consolidated the two cases into the present case. Minute Order, docket no. 86. On January 9, 2005, the Court entered an Order Regarding Case Style and Effect of Judgment, which ordered that the ease be referred to as Taltech Limited, Plaintiff, v. Esquel Enterprises Ltd., Defendant, and further ordered that specified unnamed parties would be bound by orders and judgments in the case. Order, docket no. 148.

*980 Taltech alleges infringement of its patents for a “wash-n-wear” dress shirt product and methods of producing “pucker free” seams in dress shirts, including 100% cotton shirts. See Taltech’s Compl., docket no. 22, ¶1 (Case No. C05-1318TSZ). The United States patents at issue here (collectively “the patents-in-suit”) are: (1) U.S. Patent No. 5,568,779 (the “ ’779 Patent”), which is entitled “Pucker Free Garment Seam and Method of Manufacture” and which issued October 29, 1996, and (2) U.S. Patent No. 5,590,615 (the “ ’615 Patent”), which is entitled “Pucker Free Garment Seam and Method of Manufacture” and which issued January 7, 1997. Joint Claim Chart, docket no. 85, Exs. B and C.

The parties now ask this Court to construe thirteen claim terms contained in both the ’779 and the ’615 Patents. 1

B. Legal Standard for Claim Construction

Claim construction is “a matter of law exclusively for the court,” even if the case is designated to go to a jury trial. Markman, 52 F.3d at 970-71. “While a judge is well-equipped to interpret the legal aspects of the [patent] document, he or she must also interpret the technical aspects of the [patent] document, and indeed its overall meaning, from the vantage point of one skilled in the art.” Pitney Bowes, Inc. v. Hewlett-Packard Co., 182 F.3d 1298, 1309 (Fed.Cir.1999).

To interpret the claims of a patent, a court first looks to “the intrinsic evidence of record: the claim, the specification, and, if in evidence, the prosecution history.” Metabolite Labs., Inc. v. Lab. Corp. of Am. Holdings, 370 F.3d 1354, 1373 (Fed.Cir. 2004). The intrinsic evidence is “the most significant source of the legally operative meaning of disputed claim language.” Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed.Cir.1996). A court may also consider extrinsic evidence, which “consists of all evidence external to the patent and prosecution history, including expert and inventor testimony, dictionaries, and learned treatises.” Phillips v. AWH Corp., 415 F.3d 1303, 1317 (Fed.Cir. 2005) (internal quotations omitted). Extrinsic evidence is most useful to help a court understand the underlying technology and the way in which one skilled in the art might use the claim terms. See Phillips, 415 F.3d at 1318-19; Pitney Bowes, 182 F.3d at 1309. Extrinsic evidence, however, is less reliable than intrinsic evidence in determining how to interpret claim terms. Phillips, 415 F.3d at 1318-19. Courts may rely on extrinsic evidence to construe claim terms only if “the patent documents, taken as a whole, are insufficient to enable the court to construe disputed claim terms.” Pitney Bowes, 182 F.3d at 1308-09; see also Interactive Gift Express, Inc. v. Compuserve, Inc., 256 F.3d 1323, 1332 (Fed.Cir.2001) (“Relying on extrinsic evidence to construe a claim is ‘proper only when the claim language remains genuinely ambiguous after consideration of the intrinsic evidence.’ ”)

Primarily, then, a court focuses on intrinsic evidence to construct the claims. Within the intrinsic evidence, a court first looks to the words of the claims themselves to define the scope of the patented invention. Vitronics, 90 F.3d at 1582. “It is a bedrock principle of patent law that the claims of a patent define the invention *981 to which the patentee is entitled the right to exclude.” Phillips, 415 F.3d at 1312 (internal quotations omitted). The words of a claim “are generally given their ordinary and customary meaning.” Id. (quoting Vitronics, 90 F.3d at 1582). “[T]he ordinary and customary meaning of a claim term is the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention, i.e., as of the effective filing date of the patent application.” Id. at 1313. “[T]he person of ordinary skill in the art is deemed to read the claim term not only in the context of the particular claim in which the disputed term appears, but in the context of the entire patent, including the specification.” Id.; see also ACTV, Inc. v. Walt Disney Co., 346 F.3d 1082, 1088 (Fed.Cir.2003) (considering the context of surrounding words of the claim); Vitronics, 90 F.3d at 1582 (considering other claims of the patent in question). “In some cases, the ordinary meaning of claim language as understood by a person of skill in the art may be readily apparent even to lay persons, and claim construction in such cases involves little more than the application of the widely accepted meaning of commonly understood words.” Phillips, 415 F.3d at 1314. “In such circumstances, general purpose dictionaries may be helpful.”
