MEMORANDUM OPINION

SUE L. ROBINSON, District Judge.

I. INTRODUCTION

Plaintiff CyberFone Systems, LLC ("plaintiff'), previously named LVL Patent Group, LLC, is the assignee of U.S. Patent Nos. 6, 044, 382 ("the '382 patent"), 5, 805, 676 ("the '676 patent"), 5, 987, 103 ("the '103 patent"), 8, 019, 060 ("the '060 patent") and 7, 334, 024 ("the '024 patent"), relating to telecommunications technologies. Plaintiff initially asserted infringement of combinations of these patents against a total of 175 defendants and 970 accused products across a span of 21 related cases. The court has since granted defendants' motion for summary judgment of invalidity as to the '060 patent. Presently before the court is the issue of claim construction of three disputed limitations of the remaining patents ("the patents-in-suit").

II. STANDARD OF REVIEW

Claim construction is a matter of law. Phillips v. AWH Corp., 415 F.3d 1303, 1330 (Fed. Cir. 2005) (en banc). Claim construction focuses on intrinsic evidence - the claims, specification and prosecution history - because 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); Markman v. Westview Instruments, Inc., 52 F.3d 967, 979 (Fed. Cir. 1995) (en banc), aff'd, 517 U.S. 370 (1996). Claims must be interpreted from the perspective of one of ordinary skill in the relevant art at the time of the invention. Phillips, 415 F.3d at 1313.

Claim construction starts with the claims, id. at 1312, and remains centered on the words of the claims throughout. Interactive Gift Express, Inc. v. Compuserve, Inc., 256 F.3d 1323, 1331 (Fed. Cir. 2001). In the absence of an express intent to impart different meaning to claim terms, the terms are presumed to have their ordinary meaning. Id. Claims, however, must be read in view of the specification and prosecution history. Indeed, ...
