Morris Routing Technologies v. Comcast: 7 Network Routing Patents, Resolved in 120 Days
Morris Routing Technologies, LLC filed suit against Comcast in the Eastern District of Texas, asserting seven patents covering network routing technologies across Comcast’s broadband, SD-WAN, 5G, and enterprise networking infrastructure. The case resolved in just 120 days — a timeline that strongly suggests a negotiated settlement reached before any substantive court rulings.
Seven Network Routing Patents Meet a Swift Resolution Against Comcast
On August 7, 2025, Morris Routing Technologies, LLC filed a patent infringement action in the Eastern District of Texas (Case No. 4:25-cv-00853) before Judge Sean D. Jordan, asserting seven US patents — US10382327B1, US10404582B1, US10397100B1, US10389625B1, US10419334B1, US11012344B1, and US10652133B1 — against Comcast Corp. and related Comcast entities including Comcast Business Communications, LLC and Comcast Cable Communications, LLC d/b/a Xfinity. The patents-in-suit relate to network routing technologies and were asserted against a wide swath of Comcast’s commercial and consumer infrastructure.
The case closed on December 5, 2025, just 120 days after filing, via a joint stipulation of dismissal. Under its terms, Morris Routing Technologies’ infringement claims against Comcast were dismissed with prejudice, permanently extinguishing those claims. Comcast’s counterclaims — which typically include invalidity and non-infringement defenses — were dismissed without prejudice, preserving Comcast’s ability to reassert them if circumstances change. Each party bears its own costs and fees, which is a standard commercial resolution term and does not indicate judicial fee-shifting under 35 U.S.C. § 285.
A 120-day resolution — before claim construction, any substantive Markman hearing, or discovery disputes — is consistent with a confidential licensing agreement or financial settlement reached shortly after the complaint was served. The asymmetric dismissal structure (plaintiff with prejudice, defendant without prejudice) is a commercially rational outcome: Morris Routing Technologies secures finality and likely consideration, while Comcast retains theoretical flexibility on its invalidity counterclaims. What the public record does not reveal is the financial terms, any licensing arrangement, or whether other Comcast entities outside the named defendants received a license.

Dismissed with prejudice: what the asymmetric dismissal structure means
Plaintiff’s claims dismissed with prejudice — a permanent bar
A dismissal with prejudice under Federal Rule of Civil Procedure 41 operates as a final adjudication on the merits for claim-preclusion purposes. Morris Routing Technologies cannot refile these seven patent infringement claims against the named Comcast entities in any federal court. This finality is the hallmark of a resolved dispute — typically reflecting payment of consideration in exchange for a covenant not to sue.
Permanent claim barComcast’s counterclaims dismissed without prejudice — preserving optionality
Comcast’s invalidity and related counterclaims were dismissed without prejudice, meaning they are not extinguished and could theoretically be reasserted. In practice, this structure is standard in patent settlements: the patent holder secures a with-prejudice bar on infringement claims while the accused infringer retains nominal flexibility. The practical significance of Comcast’s preserved counterclaims is limited unless the patents are re-asserted against a different Comcast entity or product line not covered by any license.
Counterclaims preservedMorris Routing Technologies exits with finality and likely consideration
The rapid resolution — 120 days from filing — and the with-prejudice dismissal of Morris Routing Technologies’ own claims suggest the plaintiff achieved its primary commercial objective, most plausibly a licensing fee or structured payment. The seven patents-in-suit remain active and enforceable against third parties not covered by any agreement reached here, preserving Morris Routing Technologies’ broader licensing program.
Likely licensing outcomeComcast secures IP peace; seven routing patents remain live against others
Comcast’s resolution removes litigation risk across its broadband, SD-WAN, 5G, MPLS, and enterprise networking product lines named in the complaint. However, the seven asserted patents remain valid and enforceable — operators in adjacent network infrastructure markets, ISPs, cloud networking providers, and enterprise SD-WAN vendors should treat this case as a signal that this portfolio is actively monetised and prepared for litigation.

Official order — verbatim text
The joint stipulation reflects a bilaterally negotiated commercial resolution rather than a court-determined outcome. The asymmetric dismissal structure — plaintiff’s infringement claims extinguished with prejudice while Comcast’s counterclaims survive without prejudice — is a legally precise drafting choice consistent with a confidential licensing or settlement agreement. The equal cost allocation clause confirms no judicial finding of exceptional case conduct under 35 U.S.C. § 285 was sought or made. No claim construction, summary judgment, or validity ruling was issued, leaving the merits of infringement and invalidity unresolved on the public record.
US10382327B1 — Network routing and traffic management patent portfolio
The seven patents-in-suit — US10382327B1, US10404582B1, US10397100B1, US10389625B1, US10419334B1, US11012344D1, and US10652133B1 — are US grant patents in the network routing domain, with application numbers filed across 2018 and 2019 based on the corrected application number data. The ‘B1’ designation indicates these are utility patents granted without prior publication, suggesting the applications were examined and issued without a published pre-grant application — a characteristic that can affect prior art search strategies in IPR proceedings. The patents collectively appear to cover routing methods, traffic management, and path control techniques applicable to both enterprise (SD-WAN, WAN, LAN, MPLS) and carrier-grade (broadband, 5G, Cell Xhaul, Metro, Core) network architectures.
The breadth of the accused Comcast product set — spanning consumer broadband (Xfinity), enterprise networking (SD-WAN, WAN, MPLS), carrier infrastructure (5G, Cell Xhaul, Metro, Core), CDN, and wholesale networks — signals that the patents-in-suit likely carry broad independent claims directed at fundamental routing operations rather than narrow implementation-specific features. For competitors in the ISP, enterprise networking, cloud networking, and telecoms infrastructure markets, this portfolio represents a live enforcement risk. The fact that seven patents were asserted simultaneously suggests a licensing programme designed to maximise claim coverage across diverse routing architectures and make design-around strategies materially more difficult.
Should your team run an FTO against the Morris Routing Technologies portfolio?
Any organisation deploying SD-WAN, MPLS, 5G backhaul, broadband access, or enterprise WAN infrastructure should treat the seven patents asserted in this case as live FTO targets. Morris Routing Technologies has demonstrated willingness to litigate in E.D. Texas against a major US cable operator, and the portfolio’s broad product coverage — from consumer broadband to enterprise SDN — suggests claim language designed to capture common routing operations rather than narrow proprietary implementations. ISPs, managed network service providers, cloud networking vendors, and enterprise SD-WAN platform operators face the highest exposure.

What this case signals for the network routing and SD-WAN IP landscape
Seven routing patents, one major cable operator, and a 120-day resolution: the Morris Routing Technologies portfolio is a live licensing risk for network infrastructure players.
E.D. Texas remains the preferred venue for network routing NPE actions
Morris Routing Technologies filed in the Eastern District of Texas — the dominant forum for NPE patent assertions. Judge Sean D. Jordan’s docket, combined with E.D. Texas’s established claim construction and case management practices, creates predictable litigation timelines. ISPs and enterprise network operators should factor E.D. Texas venue risk into their IP strategy when evaluating routing technology acquisitions or product launches.
A 120-day resolution signals a well-prepared licensing demand, not a weak case
Fast resolutions in NPE cases filed by specialist patent monetisation entities — particularly those represented by experienced patent plaintiff firms like Devlin Law Firm — typically reflect structured pre-suit licensing demands backed by claim charts. The speed here suggests Comcast’s legal team assessed infringement risk early and opted for commercial resolution over prolonged litigation. This pattern is common in network infrastructure patent disputes involving multiple patents across broad product lines.
Morris v Comcast — key questions answered
Morris Routing Technologies asserted seven US patents: US10382327B1, US10404582B1, US10397100B1, US10389625B1, US10419334B1, US11012344B1, and US10652133B1. The patents relate to network routing technologies and were asserted against Comcast’s broadband, SD-WAN, 5G, MPLS, Metro, Core, and enterprise networking products and services.
The case was resolved via a joint stipulation of dismissal filed approximately 120 days after the complaint. Morris Routing Technologies’ infringement claims were dismissed with prejudice — permanently barring refiling — while Comcast’s counterclaims were dismissed without prejudice. Each party bore its own attorneys’ fees and costs. The terms are consistent with a confidential settlement or licensing agreement, though no financial terms were disclosed in the public record.
The with-prejudice dismissal bars Morris Routing Technologies from reasserting the same seven infringement claims against the named Comcast entities (Comcast Business Communications, LLC; Comcast Cable Communications Management, LLC; and Comcast Cable Communications, LLC d/b/a Xfinity). However, the underlying patents remain valid and enforceable against all other parties not covered by any license or settlement agreement reached in this case.
The Eastern District of Texas is a consistently preferred venue for NPE patent assertions due to its established patent case management practices, experienced patent judiciary, and plaintiff-favourable procedural history. Morris Routing Technologies, represented by Devlin Law Firm LLC — a specialist patent plaintiff practice — selected E.D. Texas as the filing forum. Comcast entities are generally subject to venue in E.D. Texas given their nationwide network operations.
The complaint targeted a broad range of Comcast’s commercial and consumer network infrastructure, including Ethernet, broadband, Cell Xhaul, access, core, metro, and edge networks; datacenters and CDN; mobile and 5G; MVNO; nationwide WiFi; wholesale networks; and private enterprise networking products including SD-WAN, WAN, SDN, LAN, and MPLS offerings. The breadth of the accused product set suggests the asserted patents carry broad independent claims covering fundamental routing operations.
