Opinion

IN THE UNITED STATES DISTRICT COURT FOR THE EASTERN DISTRICT OF TEXAS MARSHALL DIVISION

ENTROPIC COMMUNICATIONS, LLC, § § Plaintiff, § § v. § CIVIL ACTION NO. 2:22-CV-00125-JRG § CHARTER COMMUNICATIONS, INC., § § Defendant.

MEMORANDUM ORDER Before the Court is Plaintiff Entropic Communications, LLC’s Motion to Strike Opinions of Dr. Kevin Almeroth. (Dkt. No. 175.) Defendant Charter Communications, Inc. opposes the Motion. (See Dkt. No. 213.) For the following reasons, the motion is GRANTED-IN-PART and DENIED-IN-PART. I. BACKGROUND Dr. Almeroth is Charter’s technical expert. Entropic moves to strike various portions of his report. II. LEGAL STANDARD An expert witness may provide opinion testimony if “(a) the expert's scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue; (b) the testimony is based on sufficient facts or data; (c) the testimony is the product of reliable principles and methods; and (d) the expert has reliably applied the principles and methods to the facts of the case.” FED. R. EVID. 702. Rule 702 requires that judges act as gatekeepers to ensure “that an expert’s testimony both rests on a reliable foundation and is relevant to the task at hand.” Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993). However, “[t]he inquiry envisioned by Rule 702 is ... a flexible one.” Id. at 594; see also Kumho Tire Co. v. Carmichael, 526 U.S. 137, 150 (1999) (“Daubert makes clear that the factors it mentions do not constitute a ‘definitive checklist or test.’”). While the party offering the expert bears the burden of showing that the testimony is

reliable, it “need not prove to the judge that the expert’s testimony is correct....” Johnson v. Arkema, Inc., 685 F.3d 452, 459 (5th Cir. 1999) (citing Moore v. Ashland Chem. Inc., 151 F.3d 269, 276 (5th Cir. 1998)). “Vigorous cross-examination, presentation of contrary evidence, and careful instruction on the burden of proof are the traditional and appropriate means of attacking shaky but admissible evidence.” Daubert, 509 U.S. at 596 (citation omitted). III. ANALYSIS A. Opinions on the Essentiality of DOCSIS Entropic moves to strike paragraphs 4, 5, 21, and 25–96 of Dr. Almeroth’s opening report. (Dkt. No. 175 at 1.) In these paragraphs, Dr. Almeroth opines that the ’690, ’008, ’826, and ’682 Patents are “‘essential for compliance with’ DOCSIS specifications.” (See id.) Entropic argues that these paragraphs should be struck because they contain opinions that

are unreliable as a matter of law. (Id. at 1–2.) Specifically, these opinions are unreliable, Entropic argues, because Dr. Almeroth does not perform an element-by-element analysis of essentiality, even though he claims that the’690, ’008, ’826, and ’682 Patents are essential to the DOCSIS standard. (See id. (quoting INVT SPE LLC v. Int'l Trade Comm’n, 46 F.4th 1361, 1377 (Fed. Cir. 2022) (“Claims are standard essential if ‘the reach of the claims includes any device that practices the standard.’” (citation omitted))).) Entropic argues that this deficiency infects the entirety of Dr. Almeroth’s opinions on this topic. (See id. at 2–6.) In response, Charter argues that Entropic has not cited any case or contract language requiring Dr. Almeroth to do an element-by-element analysis. (Dkt. No. 213 at 1.) Rather, Charter argues, the license extends to “any patented inventions described in the Specifications,” which does not require a claim-by-claim analysis. (Id. at 1–2.) Charter contends that Dr. Almeroth’s “patent-specific analysis began with an assessment of the patent as a whole, claim 1 of each respective patent, and the accused devices.” (Id. at 2.) Charter then describes such analyses in

detail. (Id. at 2–4.) In reply, Entropic re-urges that an element-by-element analysis is required for an essentiality analysis. (Dkt. No. 241 at 1 (quoting, among others, INVT SPE, 46 F.4th at 1377).) Further, Entropic argues that “Dr. Almeroth fails to show that any claim is essential for practicing the standard.” (Id. at 2.) Charter argues in sur-reply that Entropic is missing the point; there are two ways for a patent to be covered under the license: (1) “patents . . . and applications essential for compliance with the Specifications” and (2) “patented inventions described in the Specifications.” (Dkt. No. 273 at 1.) The Court finds that these paragraphs should not be struck. The license extends to “patents

. . . and applications essential for compliance with the [standard]” and to “any patented inventions described in the [standard].” (Dkt. No. 213-2 at 2.) The use of “patents, all issued patents, pending applications and subsequently filed applications,” in defining “Licensed Technology” governs here. An analysis requiring that all claims be analyzed would replace “patents, all issued patents, pending applications and subsequently filed applications” with “all claims.” As the grant provides that “patents” and “applications” define the “Licensed Technology” not “claims” the Court must give these terms meaning. B. Opinions Regarding Non-Infringing Alternatives Entropic moves to strike paragraphs 100–144 of Dr. Almeroth’s opening report. (Dkt. No. 175 at 6.) In these paragraphs, Dr. Almeroth opines that “as a non-infringing alternative, Charter could make use of cable modems and set top boxes that rely on MaxLinear chips instead of the accused Broadcom chips.” (See id.) Charter opposes this request. (See Dkt. No. 213.) The Court notes that it previously granted summary judgment that the Broadcom chips were not non-infringing alternatives. Accordingly, these paragraphs are irrelevant and should be

struck. C. References to the Court’s Claim Construction Order The Court issued its Claim Construction Memorandum Opinion and Order (“Claim Construction Order”) (Dkt. No. 123) on June 26, 2023. The Order states: The parties are ORDERED that they may not refer, directly or indirectly, to each other’s claim construction positions in the presence of the jury. Likewise, the parties are ORDERED to refrain from mentioning any portion of this opinion, other than the actual definitions adopted by the Court, in the presence of the jury. Any reference to claim construction proceedings is limited to informing the jury of the definitions adopted by the Court.
