WSOU Investments v. TP-Link Technologies — Dismissed With Prejudice After 3+ Years
WSOU Investments LLC filed a patent infringement action against TP-Link Technologies Co., Ltd. in the Western District of Texas, asserting US7965726B2 across a broad range of networking products including routers, wireless adapters, and cable modems. The case closed on a joint motion to dismiss with prejudice, with each side bearing its own costs — a resolution that permanently bars WSOU from reasserting these specific claims against TP-Link.
Joint dismissal ends 3-year networking patent dispute in W.D. Texas
On October 31, 2020, WSOU Investments LLC — a patent assertion entity holding a portfolio of patents originating from Nokia — filed suit against TP-Link Technologies Co., Ltd. in the Western District of Texas before Judge Alan D. Albright, asserting infringement of US7965726B2. The accused products span a wide range of TP-Link’s consumer and commercial networking portfolio, including routers, wireless adapters, cable modems, range extenders, switches, IP cameras, powerline adapters, and smart home devices.
The case closed on January 3, 2024, when the court granted a joint motion to dismiss with prejudice. Both WSOU and TP-Link agreed that all claims asserted by WSOU would be dismissed with prejudice, and that each party would bear its own costs, expenses, and attorneys’ fees. Dismissal with prejudice carries significant legal weight: it is a final adjudication on the merits, meaning WSOU is permanently barred from bringing the same patent claims against TP-Link in any future proceeding.
The case ran for approximately 1,160 days before resolution — a duration consistent with complex patent disputes in the Western District of Texas. The fact that both parties filed a joint motion suggests the matter was resolved through a negotiated agreement, though the terms of any underlying settlement remain confidential and are not reflected in the public record. What drove the decision to dismiss rather than proceed to trial — whether claim construction rulings, IPR proceedings, licensing discussions, or commercial considerations — is not disclosed in the docket.

Stipulation of dismissal — official text
The court’s order adopts the parties’ joint motion verbatim, granting dismissal with prejudice on all claims WSOU asserted against TP-Link, with each side bearing its own litigation costs. The phrasing ‘all claims asserted’ limits the preclusive effect to the specific claims pleaded in this action — it does not extinguish any claims on other WSOU patents. For TP-Link, the with-prejudice language provides a complete defence to any future re-assertion of these specific claims under US7965726B2. The mutual cost allocation is commercially neutral and avoids any implied concession by either party.
US7965726B2 — Networking and Data Transmission Technology Patent
US7965726B2, filed under application number US11/401246, is a U.S. patent in the networking and data transmission technology domain. The patent was asserted by WSOU Investments, a patent assertion entity widely understood to hold patents originating from Nokia’s legacy portfolio. In this case, WSOU deployed the patent broadly across TP-Link’s product lines — covering high-speed cable modems, routers, wireless adapters, range extenders, switches, IP cameras, powerline adapters, and smart home devices — suggesting the claims are drafted at a level of abstraction that touches core packet handling or wireless communication functions common across these device categories.
For the networking hardware sector, US7965726B2 represents the type of foundational communication patent that can be applied against a wide OEM product portfolio. WSOU’s litigation campaign against networking companies in the 2020–2021 wave targeted multiple defendants simultaneously, using W.D. Texas as the preferred forum under Judge Albright’s patent-friendly docket management. The strategic risk for competitors lies in the patent’s breadth: any company manufacturing or distributing consumer or enterprise networking devices in the U.S. market should treat this patent as a live enforcement risk until it expires or is invalidated through IPR.
Should your networking product team run an FTO against US7965726B2?
If your company manufactures or distributes routers, wireless adapters, cable modems, range extenders, powerline adapters, or smart home networking devices in the U.S. market, US7965726B2 warrants a freedom-to-operate review. The fact that WSOU accused this breadth of TP-Link products — and that no claim construction was ever issued publicly — means the patent’s effective scope against your specific implementation is unresolved. A dismissal with prejudice against TP-Link creates no prior art finding or invalidity ruling that protects other parties.
PatSnap Eureka’s FTO Search Agent can map the claims of US7965726B2 against your product architecture, flag prior art that may narrow or invalidate key claims, and identify any pending IPR or post-grant proceedings that could affect the patent’s validity status. Claim monitoring alerts will notify your team if WSOU or any subsequent assignee takes further enforcement action — giving you lead time to assess exposure before a complaint lands.

What this case signals for the networking device IP landscape
WSOU’s broad product sweep and quick joint dismissal reveal both the pressure tactics and the limits of PAE enforcement against established hardware OEMs.
WSOU’s wide product scope creates maximum defendant exposure at filing
By naming routers, modems, cameras, powerline adapters, and smart home devices, WSOU maximised the royalty base at the pleading stage. Networking device makers should assess the full breadth of accused product categories — not just primary SKUs — when evaluating infringement exposure from similar PAE complaints.
W.D. Texas dismissals with prejudice often follow claim construction setbacks
Judge Albright’s court has seen a high volume of WSOU filings. Cases that resolve via joint dismissal with prejudice after 2–3 years frequently follow unfavourable claim construction rulings or inter partes review developments. While the specific trigger here is not public, monitoring IPR filings against US7965726B2 may reveal the strategic inflection point.
WSOU v TP-Link — key questions answered
The case was dismissed with prejudice by joint motion of both parties on January 3, 2024. All claims asserted by WSOU Investments against TP-Link were dismissed, with each side bearing its own costs, expenses, and attorneys’ fees. The dismissal with prejudice permanently bars WSOU from reasserting the same claims under US7965726B2 against TP-Link.
WSOU asserted US7965726B2 (application number US11/401246), a patent in the networking and data transmission technology domain. The patent was applied across a broad range of TP-Link products including routers, wireless adapters, cable modems, range extenders, IP cameras, powerline adapters, and smart home devices.
A dismissal with prejudice operates as a final adjudication on the merits. It means WSOU cannot refile any of the claims it asserted under US7965726B2 against TP-Link in any future proceeding. This gives TP-Link a complete procedural defence against re-assertion of these specific patent claims. It does not, however, affect WSOU’s ability to assert the patent against other defendants.
The Western District of Texas, presided over by Judge Alan D. Albright during this period, was a preferred venue for patent assertion entities including WSOU due to its historically faster trial schedules and patent-friendly procedural reputation. WSOU filed numerous patent infringement suits in this district in 2020–2021 as part of a broader enforcement campaign targeting networking OEMs.
WSOU’s complaint identified a wide range of TP-Link products as accused of infringing US7965726B2, including high-speed cable modems, routers, wireless routers, range extenders, switches, IP cameras, media converters, mobile phones, wireless adapters, ADSL devices, smart home technology devices, power banks, powerline adapters, and print servers — effectively spanning most of TP-Link’s consumer networking portfolio.
