Opinion

CLAIM CONSTRUCTION

CASTILLO, District Judge.

Lifetime Products, Inc. (“Lifetime”) is a manufacturer of, among other things, polyethylene folding tables. Lifetime brought this patent infringement action against GSC Technology Corp. and GSC Forwarding Company, Inc. (collectively “GSC”) alleging that GSC sells tables that infringe on four of Lifetime’s patents: U.S. Patent Numbers 6,431,092 (the “ ’092 patent”), 6,530,331 (the “’331 patent”), 6,550,404 (the “ ’404 patent”) and 5,536,552 (the “ ’552 patent”). The allegedly infringing tables are: (1) the Enduro four foot table; (2) the Enduro Rochester table; (3) the 2003 Enduro six foot table; (4) the Enduro eight foot table; (5) the Enduro II four foot table; (6) the Enduro II six foot table; 1 and (7) the Enduro II five foot round table. The parties dispute the meaning of numerous terms in the patents-in-suit, so we must construe all disputed terms to permit an infringement determination.

*941 LEGAL STANDARDS

Claim construction is the exclusive duty of the Court. Markman v. Westview Instruments, Inc., 517 U.S. 370, 372, 116 S.Ct. 1384, 134 L.Ed.2d 577 (1996). To construe a claim, a court first looks to the intrinsic evidence of record, which is the patent’s claims, specification or written description, and prosecution history. Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed.Cir.1996). After considering all of the intrinsic evidence, a court may consider relevant extrinsic evidence if necessary to construe a claim. Frank’s Casing Crew & Rental Tools, Inc. v. PMR Techs., Ltd., 292 F.3d 1363, 1374 (Fed.Cir.2002).

“[T]he analytical focus must begin and remain centered on the language of the claims themselves, for it is that language that the patentee chose to use to particularly point out and distinctly claim the subject matter which the patentee regards as his invention.” Brookhill-Wilk 1, L.L.C. v. Intuitive Surgical, Inc., 334 F.3d 1294, 1298 (Fed.Cir.2003) (internal quotations omitted).

Generally, terms in a patent claim are given their plain, ordinary, and accustomed meaning to one of ordinary skill in the relevant art. After identifying the plain meaning of a disputed claim term, the court examines the written description and the drawings to determine whether use of that term is consistent with the ordinary meaning of the term.

Prima Tek II, L.L.C. v. Polypap, S.A.R.L., 318 F.3d 1143, 1148 (Fed.Cir.2003) (internal citation omitted). There is a “strong presumption” that a claim term should be accorded its ordinary meaning. Apex v. Raritan Computer, Inc., 325 F.3d 1364, 1371 (Fed.Cir.2003). “Dictionaries are always available to the court to aid in the task of determining meanings that would have been attributed by those of skill in the relevant art to any disputed terms used by the inventor in the claims.” Texas Digital Sys., Inc. v. Telegenix, Inc., 308 F.3d 1193, 1202 (Fed.Cir.2002). The presumption that a term should be accorded its ordinary meaning is only overcome if: (1) the patentee acted as his own lexicographer and defined a term differently or (2) the ordinary meaning of the term would render a claim meaningless or unamenable to construction. Prima Tek II, 318 F.3d at 1148.

A court should also consider a patent’s specification or written description. The specification should be used to construe claim terms, but the specification cannot limit the scope of a patent’s claims. Liebel-Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 904 (Fed.Cir.2004). Similarly, the specification cannot expand or broaden the scope of a patent’s claims. PSC Computer Prods., Inc. v. Foxconn Int'l, Inc., 355 F.3d . 1353, 1359 (Fed.Cir.2004); Unique Concepts, Inc. v. Brown, 939 F.2d 1558, 1562 (Fed.Cir.1991) (stating that permitting the specification to expand the scope of a patent’s claims “would encourage an applicant to escape examination of a more broadly-claimed invention by filing narrow claims and then, after grant, asserting a broader scope of the claims based on a statement in the specification of an alternative never presented in the claims for examination”). A court should also consider the prosecution history if it is in evidence. Vitronics, 90 F.3d at 1582.

The prosecution history can be used to construe claim terms, but it can limit the scope of a patent’s claims if the patentee expressly disclaimed a particular claim construction. Southwall Techs., Inc. v. Cardinal IG Co., 54 F.3d 1570, 1576 (Fed.Cir.1995).

Finally, a court is not required to hold an evidentiary “Markman ” hearing when undertaking claim construction. *942 Ballard Med. Prods, v. Allegiance Healthcare Corp., 268 F.3d 1352, 1358 (Fed.Cir.2001).

CLAIM CONSTRUCTION 2

1. Disputed Terms in the ’092 Patent

We must construe the following disputed terms in the ’092 patent: (1) frame, (2) mounting surface, (3) retaining assembly, (4) mounting member, (5) securing member, (6) foot portion, and (7) first end and second end.

A. Frame

’092 patent claim 76 states that the table comprises “a frame connected to the mounting surface of the table top.” (R. 58, Keller Decl., Ex. A, ’092 Patent, Claim 76.) GSC asserts that none of its tables have frames because they only have side rails. Lifetime claims that the term “frame” is broad enough to include a structure that is composed only of side rails. To construe this term, we must first consider the patent’s claims. Claim 76 states that a frame includes “a pair of generally parallel disposed side rails,” but the claims do not explicitly state whether a frame can consist only of side rails. Accordingly, we must consider the patent’s specification.

The specification defines frame broadly.
