Huawei v. Verizon: Federal Circuit Affirms Unpatentability of Bridge Forwarding Patent
Huawei Technologies appealed to the Federal Circuit after its patent US7965709B2, covering a bridge forwarding method and apparatus, was found unpatentable. A three-judge panel unanimously affirmed the ruling in 409 days, leaving the patent cancelled.
Federal Circuit unanimously affirms unpatentability of Huawei's bridge forwarding patent
Huawei Technologies, Co., Ltd. filed this appeal at the Court of Appeals for the Federal Circuit on 21 March 2022, challenging a prior finding that US7965709B2 — a patent directed to a bridge forwarding method and apparatus in network communications — was unpatentable. Verizon Communications, Inc. was the opposing party. Huawei was represented by Fish & Richardson PC, with counsel including David M. Barkan, Michael Timothy Hawkins, Nicholas Stephens, and Robert Courtney.
The Federal Circuit issued its decision on 4 May 2023. A per curiam panel composed of Circuit Judges Lourie, Bryson, and Reyna unanimously affirmed the finding of unpatentability. The recorded basis of termination is 'Unpatentable'; the docket order states the cause was heard and adjudged 'AFFIRMED' per curiam. The verdict cause is recorded as an Invalidity/Cancellation Action on grounds of patentability.
The case resolved in 409 days, which is consistent with standard Federal Circuit appellate timelines for patent validity appeals. The unanimous per curiam disposition suggests the panel found no reversible error requiring extended written analysis. The specific arguments raised by Huawei on appeal and the precise prior art or grounds underlying the unpatentability finding are not detailed in the available record.

US7965709B2 — Bridge Forwarding Method and Apparatus
Network equipment manufacturers, telecoms carriers, and software-defined networking vendors implementing bridge forwarding or Layer 2 switching architectures should assess their exposure to Huawei's broader patent family in this space. Although US7965709B2 has been affirmed unpatentable, related continuation applications or divisional patents within the same family (application US11/583760) may still be active and present assertion risk. A targeted FTO review is warranted before clearing this domain.
Official order — verbatim text
The per curiam order — 'AFFIRMED' by Judges Lourie, Bryson, and Reyna — confirms the panel found no reversible error in the underlying unpatentability determination. A per curiam disposition without an extended written opinion typically indicates the appellate standard of review was applied and the outcome was deemed sufficiently clear on the record presented. The recorded basis of termination is 'Unpatentable,' consistent with the affirmance of an invalidity or cancellation ruling below.
Federal Circuit affirms: what the ruling means for both parties
What 'AFFIRMED' means at the Federal Circuit
An affirmance by the Federal Circuit means the panel found no reversible error in the decision below. The lower tribunal's finding of unpatentability is upheld and carries full legal effect. A per curiam affirmance, issued without an extended written opinion, signals the panel viewed the outcome as sufficiently clear on the existing record to require no further elaboration.
No reversible error foundHuawei's bridge forwarding patent remains cancelled
As the appellant and patent holder, Huawei's appeal failed to overturn the unpatentability finding. US7965709B2 is no longer enforceable. Huawei's appellate options at this level are exhausted. Any further challenge would require a petition for en banc rehearing or a certiorari petition to the U.S. Supreme Court — a high bar following a unanimous per curiam ruling.
Patent unenforceableVerizon prevails: no exposure under US7965709B2
As the appellee, Verizon successfully defended the unpatentability finding. The affirmance eliminates any infringement risk or damages exposure associated with US7965709B2. The result provides Verizon and similarly situated network operators with certainty that this specific bridge forwarding patent cannot be asserted against their products or services.
Infringement risk eliminatedBridge forwarding technology freed from this patent claim
The cancellation of US7965709B2 removes a potential licensing or litigation overhang for network equipment manufacturers and carriers implementing bridge forwarding methods. Competing filers in this technology domain should audit their own portfolios for overlapping claims, and monitor Huawei's continuation or divisional filing activity for any surviving related patents that may cover similar subject matter.

R&D signals in the network bridge forwarding and switching IP space
Forward-looking patent intelligence derived from the Huawei v. Verizon Federal Circuit proceeding — tracking portfolio activity, filing trends, and white space in network switching.
Huawei's network forwarding patent portfolio beyond US7965709B2
Huawei holds an extensive filing presence in network switching, packet forwarding, and bridge protocols. The cancellation of one patent does not indicate retreat from this domain. Tracking Huawei's active filings and continuations in Layer 2 and Layer 3 forwarding technology reveals where future assertion risk may concentrate for network equipment vendors and carriers.
Huawei network IP activityFiling trends in bridge forwarding and network switching patents
Bridge forwarding and software-defined networking convergence is driving new filing activity across telecoms incumbents and new entrants. Monitoring claim trends in IEEE 802.1 bridge protocols, VLAN forwarding, and multi-path switching reveals how the prior art landscape is evolving — and which technical approaches are accumulating the densest patent coverage.
Network switching filing trendsVerizon's patent position in network infrastructure technology
Verizon's successful defence in this validity challenge reflects a broader trend of large carriers leveraging inter partes review and cancellation proceedings to clear blocking patents in their network infrastructure supply chain. Examining Verizon's own patent portfolio in switching and forwarding technology reveals potential cross-licensing leverage and defensive filing priorities.
Verizon network IP strategyAdjacent white space near cancelled bridge forwarding claims
The cancellation of US7965709B2 creates potential white space in specific bridge forwarding claim configurations. R&D teams developing next-generation network virtualisation, SDN-based forwarding, or programmable data plane architectures may find claim territory adjacent to the cancelled patent's scope available for new filings — particularly in dynamic bridge table management and forwarding rule optimisation.

What this case signals for the network switching IP landscape
A unanimous Federal Circuit affirmance of unpatentability carries weight beyond the two parties — here is what practitioners should track.
Per curiam affirmance raises the bar for Huawei revival of this patent family
A unanimous per curiam ruling leaves little procedural room for further appellate relief. Patent holders in Huawei's position typically face an uphill battle at en banc or Supreme Court level after such a disposition. IP teams monitoring Huawei's bridge forwarding portfolio should track any continuation filings that might attempt to capture surviving claim scope.
Network carriers gain enforceability certainty on bridge forwarding methods
With US7965709B2 cancelled and affirmed dead on appeal, telecoms and network equipment vendors implementing bridge forwarding architectures face one fewer assertion risk. Legal teams should nonetheless run freedom-to-operate checks against Huawei's related US patent family before concluding this space is fully clear.
Huawei v Verizon — key questions answered
The Federal Circuit affirmed the finding of unpatentability in Case No. 22-1553. A per curiam panel of Judges Lourie, Bryson, and Reyna issued the affirmance on 4 May 2023, upholding the invalidity of US7965709B2, which covers a bridge forwarding method and apparatus. The recorded basis of termination is 'Unpatentable.'
US7965709B2, filed under application number US11/583760, protects a bridge forwarding method and apparatus — technology relevant to how data is routed across network bridge devices in telecommunications systems. The patent was held by Huawei Technologies and challenged by Verizon Communications in a proceeding recorded as an Invalidity/Cancellation Action on patentability grounds.
A per curiam affirmance means the Federal Circuit panel unanimously found no reversible error in the unpatentability determination below, without issuing an extended written opinion. US7965709B2 is cancelled and no longer enforceable. Huawei's remaining options would be a petition for en banc rehearing or a certiorari petition to the U.S. Supreme Court — both high-bar proceedings following a unanimous disposition.
Not necessarily. The cancellation of US7965709B2 eliminates exposure under that specific patent, but Huawei holds a broad portfolio in network switching and forwarding technology. Related continuation or divisional applications within the same family (application US11/583760) may remain active. A dedicated FTO analysis covering the full Huawei network forwarding patent family is advisable before concluding the space is clear.
