Entropic v. Comcast: 12-Patent MoCA Infringement Action Consolidated (C.D. Cal.)
Entropic Communications, LLC brought a 12-patent infringement action against Comcast Corp. and its cable affiliates in the Central District of California, asserting patents covering MoCA, broadband coaxial LAN, and multi-carrier modulation technologies. Within 245 days of filing, the Court granted a joint stipulation consolidating this case with three related Entropic actions — against DISH, Cox, and AT&T/DIRECTV — into a single pretrial proceeding under lead case 2:23-cv-01043.
Entropic's Broadband IP Campaign Against Comcast: Consolidation Before Markman
Entropic Communications, LLC filed Case No. 2:23-cv-01048 on 10 February 2023 in the U.S. District Court for the Central District of California, asserting infringement of 12 patents by Comcast Corp., Comcast Cable Communications, LLC, and Comcast Cable Communications Management, LLC. The asserted patents span a broad portfolio of multimedia-over-coaxial-cable (MoCA) technologies, including broadband local area networking over coaxial cable, multi-carrier modulation, constellation scrambling, quality-of-service architectures, and network packet aggregation.
The recorded Basis of Termination is 'Case Consolidated.' The docket order states that the Court granted the parties' Joint Stipulation to Consolidate Cases, consolidating this action with three related Entropic cases — 2:23-cv-01043 (v. DISH), 2:23-cv-01047 (v. Cox), and 2:23-cv-05253 — into a single pretrial action through the date of the Markman hearing, with all filings to be made in the low-numbered case 2:23-cv-01043. The Clerk was directed to close this case administratively.
The case reached administrative closure within approximately eight months of filing, before any Markman ruling was entered in this docket. The consolidation order preserves the right of any party to move for severance for good cause at any time. The substantive merits, claim construction positions, and ultimate resolution of Entropic's infringement claims against Comcast remain pending in the lead consolidated proceeding; those outcomes are not disclosed in the available record for this case number.

245 days from filing to administrative closure — resolved at the consolidation stage, before Markman
US10432422B2 and 11 further patents — MoCA and broadband coaxial network technologies
Any company designing, manufacturing, or deploying broadband networking equipment or services that operate over coaxial cable — including MoCA-compliant home network devices, cable modems, gateway devices, or DOCSIS infrastructure — should evaluate freedom-to-operate against the 12 patents Entropic has actively asserted in this consolidated enforcement campaign. The defendants named span the largest U.S. cable and satellite operators, suggesting the portfolio is being enforced broadly across the industry.
Official order — verbatim text
The consolidation order is procedural rather than substantive: it closes this docket administratively and redirects all pretrial activity — including claim construction — to lead case 2:23-cv-01043. No merits determination, no infringement finding, and no validity ruling was made in this case. The order does not resolve Entropic's claims against Comcast; it concentrates them alongside parallel claims against DISH, Cox, and AT&T/DIRECTV in a single coordinated proceeding.

R&D signals in the MoCA and coaxial broadband networking IP space
Forward-looking patent intelligence derived from Entropic's 12-patent enforcement campaign against Comcast and major U.S. cable operators — relevant for R&D and IP teams in the broadband networking sector.
Entropic's MoCA patent portfolio: breadth and filing trajectory
Entropic Communications has assembled a portfolio spanning physical layer, protocol, QoS, and home networking domains for coaxial broadband — with application dates ranging from the early 2000s to mid-2010s. Tracking continuation filings, recent assignments, and any new applications in this family tree is critical for understanding future enforcement vectors beyond the 12 currently asserted patents.
Entropic MoCA patent portfolioMoCA and coaxial LAN filing trends: who is innovating now?
The MoCA and broadband-over-coaxial technology space has seen sustained filing activity from cable equipment makers, semiconductor firms, and network operators. Understanding current filing trends — particularly around Wi-Fi/MoCA hybrid gateway devices and DOCSIS 3.1/4.0 integration — can reveal where the next generation of IP concentration is forming and which areas remain relatively open.
MoCA coaxial LAN filing trendsComcast's own coaxial and home network patent position
As a major infrastructure operator, Comcast holds its own portfolio in broadband access and home networking technologies. Analysing Comcast's patent filings in the MoCA, DOCSIS, and in-home networking space can reveal potential defensive prior art, cross-licensing leverage, and whether Comcast is actively building IP positions that could offset or complicate Entropic's enforcement strategy.
Comcast broadband home network IPAdjacent innovation opportunities near the asserted MoCA patent claims
Claim scope in the Entropic portfolio centres on coaxial-specific protocols, constellation scrambling, and QoS architectures. Adjacent areas — such as fibre-to-the-premises in-home distribution, Wi-Fi 7 mesh integration, and software-defined home networking — may represent engineering paths that sit outside current claim boundaries. FTO and white-space analysis in these adjacencies could inform next-generation product design.

What this consolidation signals for the MoCA and coaxial broadband IP landscape
Entropic's simultaneous multi-defendant campaign across four cases signals a coordinated enforcement strategy around MoCA and coaxial broadband IP.
Multi-defendant consolidation raises Markman stakes for the entire cable industry
By consolidating cases against Comcast, DISH, Cox, and AT&T/DIRECTV into a single pretrial proceeding, the Court's eventual claim construction ruling will bind all defendants simultaneously. A single adverse Markman outcome for Entropic — or a broad construction — will set precedent across the largest U.S. cable and satellite operators at once, amplifying the commercial impact of every claim term disputed.
Twelve-patent portfolio assertion signals long-term enforcement runway for Entropic
Asserting 12 patents across MoCA, multi-carrier modulation, QoS, and coaxial LAN in a coordinated multi-defendant campaign suggests Entropic holds a broad enough portfolio to pursue enforcement through multiple technology layers. Companies operating broadband-over-coaxial infrastructure should assess exposure not just to the lead asserted patents but to adjacent claims within the same portfolio families.
Entropic v Comcast — key questions answered
Case No. 2:23-cv-01048 was administratively closed on 13 October 2023 when the Court granted a joint stipulation consolidating it with three related Entropic cases into lead case 2:23-cv-01043. The recorded Basis of Termination is 'Case Consolidated.' No merits ruling was issued in this case number; Entropic's infringement claims against Comcast continue in the consolidated proceeding.
Entropic asserted 12 patents: US10432422B2, US8621539B1, US7889759B2, US10257566B2, US9838213B2, US8085802B1, US8631450B1, US8228910B2, US7295518B1, US7594249B2, US8363681B2, and US8320566B2. The patents cover MoCA, broadband coaxial LAN, multi-carrier modulation, constellation scrambling, QoS architecture, and network packet aggregation technologies.
A 'Case Consolidated' termination means the Court has administratively closed this case number and directed all filings to proceed in a designated lead case — here, 2:23-cv-01043. The underlying claims are not dismissed; they are active in the consolidated action. All pretrial proceedings, including Markman claim construction, continue in the lead case.
The consolidation order names DISH Network Corporation and affiliates, Cox Communications Inc. and affiliates, and DIRECTV, LLC and AT&T Services, Inc. as defendants consolidated alongside Comcast into lead case 2:23-cv-01043. All four groups of defendants are parties to the single consolidated pretrial proceeding.
The case was consolidated before any Markman (claim construction) hearing was held. The consolidation order itself specifies that the cases are consolidated for pretrial purposes 'through the date of the Markman hearing,' indicating no claim construction ruling had been issued at the time of administrative closure on 13 October 2023.
