Opinion

MEMORANDUM

YOUNG, District Judge.

I. INTRODUCTION

Ethos Technologies, Inc. (“Ethos”) brought this action against RealNetworks, Inc. (“RealNetworks”) alleging willful patent infringement by RealNetworks as to Ethos,’ U.S. Patent No. 6,049,892 (filed Feb. 24, 1997) (issued Apr. 11, 2000)(the “'892 patent”), and U.S. Patent No. 6,381,-709 (filed Apr. 3, 2000)(issued April 30, 2002) (the “'709 patent”). See Compl. [Doc. No. 1] ¶¶ 5-14. RealNetworks filed a counterclaim seeking a declaratory judgment of non-infringement and of invalidity as to the two patents. Ans. and Countercl. [Doc. No. 5] at Countercl. ¶¶ 5-30.

The patents teach a process that automatically restarts the download of a file from the internet if the initial download terminates. See '892 patent, Abstract; '709 Patent, Abstract. At trial, Ethos alleged that RealNetworks’ products infringed on claims 7-12 of the '892 patent and claims 1,2,4, and 5 of the '709 patent.

After three weeks of trial and two and a half days of deliberation, the jury returned a verdict in favor of RealNetworks. 1 The jury found that claims 7, 9 and 12 of *134 the ’892 patent and claim 1 of the '709 patent were anticipated and obvious. Jury-Verdict [Doc. No. 363] at 1-2. The jury further found that claims 8, 10, and 11 of the '892 patent were not anticipated but were obvious. Id. The jury also concluded that claims 2, 4, and 5 of the '709 patent were neither anticipated nor obvious. Id. at 2. 2 Finally, the jury found that RealNet-works did not infringe any of the claims at issue in the '892 and '709 patents. Id. at 1-3.

The Court denied Ethos’ motion for judgment as matter of law [Doc. No. 374], and writes now only to explain its ruling as to the claim construction of the disputed terms in the patents.

II. DISCUSSION

A. Standard of Review

Claim construction is matter of law with decision exclusively for the Court. Markman v. Westview Instruments, Inc., 517 U.S. 370, 372, 116 S.Ct. 1384, 134 L.Ed.2d 577 (1996) (“We hold that the construction of a patent, including terms of art within its claim, is exclusively within the province of the court.”), aff'g 52 F.3d 967, 978-79, 987 (Fed.Cir.1995) (en banc). Claim construction always begins with a review of the claim language. CAE Screenplates Inc. v. Heinrich Fiedler GmbH & Co., 224 F.3d 1308, 1316 (Fed.Cir.2000); Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed.Cir.1996). The words of the claim are generally given their ordinary and customary meaning — the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention (the effective filing date of the patent). Phillips v. AWH Corp., 415 F.3d 1303, 1313 (Fed.Cir.2005) (en banc); see also Omega Eng’g, Inc. v. Raytek Corp., 334 F.3d 1314, 1323 (Fed.Cir.2003) (‘We indulge a ‘heavy presumption’ that claim terms carry their full ordinary and customary meaning unless the patentee unequivocally imparted a novel meaning to those terms or expressly relinquished claim scope during prosecution.” (internal citations omitted)). In some cases, “the ordinary meaning of claim language as understood by a person of skill in the art is readily apparent” and “involves little more than the application of the widely accepted meaning of commonly understood words.” Phillips, 415 F.3d at 1314. Where it is not, the Court looks to other sources that show what a person of skill in the art would have understood that claim language to mean. Id. The Court primarily relies on “intrinsic evidence” of the claim, which includes the claim language itself, the specification, and the prosecution history Id. at 1314-17. The specification “is the single best guide to the meaning of a disputed term.” Id. at 1315 (quoting Vitronics, 90 F.3d at 1582). Moreover, although the prosecution history frequently lacks the clarity of the specification, it can “often inform the meaning of the claim language by demonstrating how the inventor understood the invention and whether the inventor limited the invention in the course of prosecution, making the claim scope narrower than it would otherwise be.” Id.

Extrinsic evidence — dictionaries and learned treaties — can sometimes be useful in claim construction but is generally con *135 sidered less reliable than the intrinsic record in determining how to read claim terms. Id. at 1318. The court must be careful to consider extrinsic evidence in light of the intrinsic evidence, and discount any extrinsic evidence that is at clear odds with the intrinsic evidence. See id. at 1318-19.

B. Claim Construction

The parties originally asked the Court to construe twelve terms found in either or both of the '892 and '709 patents. See generally Ethos’ Reply Markman Br. [Doc. No. 273] (“Pl.Rep.”); RealNetworks’ Reply Br. on Claim construction [Doc. No. 275] (“Def.Rep.”). At the Markman hearing, held on January 18, 2006, the parties informed the Court that they agreed to the construction of two of the ten terms— “application protocol” and “transfer protocol.” Markman Hr’g, January 18, 2006, Tr. (“Markman Tr.”) 3:14-4:2. 3 In addition, the Court declined to construe the term “testing for the existence of a viable connection,” considering the parties’ constructions so similar 4 that defining the term was unnecessary. See Vivid Technologies, Inc. v. American Science & Eng’g, Inc., 200 F.3d 795, 803 (Fed.Cir. 1999) (ruling that the Court is required to construe “only those terms ... that are in controversy, and only to the extent necessary to resolve the controversy”).

C. The Claims

Claim 7 of the '892 patent reads:

7. A process for downloading a data file from a server computer to a client computer, wherein the data file is stored on a computer readable medium connected to the server computer, wherein the process has an application protocol for sending data as a stream of data using a transport protocol over a computer network
