Monterey Research v. AMD & Qualcomm: Federal Circuit Affirms Unpatentability
Monterey Research, LLC asserted US6765407B1, covering digital configurable macro architecture, against Advanced Micro Devices and Qualcomm. The Federal Circuit affirmed the unpatentability ruling, closing a 618-day appellate proceeding with no surviving claims.
Federal Circuit closes the book on Monterey Research's macro architecture patent
Monterey Research, LLC, a patent assertion entity holding US6765407B1, brought an invalidity and cancellation action concerning that patent's claims over digital configurable macro architecture. The appeal, docketed as Case No. 22-1430 at the Court of Appeals for the Federal Circuit, named Advanced Micro Devices, Inc. and Qualcomm Incorporated as respondents. The proceeding was filed on 2 February 2022 and closed on 13 October 2023, spanning 618 days.
The Federal Circuit issued a terse but dispositive order: having considered the cause, the court ordered and adjudged the lower determination AFFIRMED. The recorded basis of termination is 'Unpatentable', confirming that the patent's claims did not survive the patentability challenge. The affirmance means the invalidity or cancellation finding made below is now binding, with no further recourse at this appellate level.
A 618-day appellate timeline is consistent with typical Federal Circuit patent appeal durations. The unpatentability finding eliminates US6765407B1 as an enforcement tool against AMD, Qualcomm, and any other potential targets. What specific grounds of unpatentability were upheld — and whether any claims were separately considered — is not detailed in the available public record.

US6765407B1 — Digital configurable macro architecture
US6765407B1 has been affirmed unpatentable by the Federal Circuit, meaning its claims are cancelled and no longer enforceable. Product and R&D teams working on digital configurable macro architecture, reconfigurable logic blocks, or programmable SoC design do not face direct infringement exposure from this specific patent. However, Monterey Research may hold additional related patents, and adjacent patents in the same technology family should be independently assessed before clearing any design.
Official order — verbatim text
The Federal Circuit's order — 'ORDERED AND ADJUDGED: AFFIRMED' — is a merits affirmance of the unpatentability determination below. The terse phrasing is consistent with a per curiam or Rule 36 affirmance, indicating the panel found the lower tribunal's reasoning legally sufficient without requiring extended written analysis. The practical effect is that US6765407B1's claims are cancelled and no longer enforceable by Monterey Research against any party.
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 appellate panel reviewed the decision below and found no reversible error — legal, factual, or procedural — sufficient to overturn it. The unpatentability finding entered at the lower tribunal is now confirmed and stands as the final disposition. No further appeal within the Federal Circuit is available; only a petition to the Supreme Court would remain as a theoretical avenue.
No reversible error foundMonterey Research's patent loses enforceability
For Monterey Research, the affirmance is terminal for US6765407B1. A patent found unpatentable cannot be asserted against any party — not AMD, not Qualcomm, not any third-party target in any future action. The patent's value as a licensing or litigation asset is extinguished by this ruling. The specific claims cancelled and the grounds of unpatentability are not detailed in the available public record.
Patent unenforceableAMD and Qualcomm obtain a final invalidity shield
Advanced Micro Devices and Qualcomm secured a binding Federal Circuit affirmance of unpatentability, meaning the asserted patent can no longer threaten their digital macro architecture products or design pipelines. The ruling provides certainty across both companies' product lines that fall within the scope of the now-cancelled claims. No further exposure to US6765407B1 exists from the available record.
Full invalidity confirmedUnpatentability affirmance raises the bar for macro architecture PAE campaigns
For the broader semiconductor and SoC sector, a Federal Circuit affirmance of unpatentability signals that digital configurable macro architecture claims of this vintage face rigorous scrutiny. Competitors operating in this design space gain freedom-to-operate benefit from the cancelled claims. Patent assertion entities holding similar legacy semiconductor architecture patents should treat this outcome as a signal to reassess claim validity before initiating enforcement campaigns.

R&D signals in digital configurable macro architecture IP
Forward-looking patent and innovation signals for semiconductor teams tracking configurable macro architecture, SoC design IP, and the portfolios of Monterey Research, AMD, and Qualcomm.
Monterey Research's remaining semiconductor patent assets
With US6765407B1 cancelled, understanding which other patents Monterey Research holds in the semiconductor and digital logic space is critical for any potential target company. Their portfolio may include additional configurable architecture, memory interface, or logic design patents that remain active and enforceable. Mapping their live filings is a proactive step for AMD, Qualcomm, and sector peers.
PAE portfolio monitoringFiling trends in digital configurable macro architecture
Digital configurable macro architecture remains an active area of semiconductor R&D, with ongoing filings from major chipmakers and fabless design houses. Tracking filing trends in this space reveals which players are staking new claim territory as legacy patents — like US6765407B1 — exit the landscape through cancellation, potentially opening white space for new and differentiated claims.
Macro architecture filing trendsAMD and Qualcomm's offensive patent positions in SoC design
Beyond their defensive success in this case, AMD and Qualcomm each maintain substantial offensive patent portfolios in SoC and programmable logic design. Analysing their recent filing activity in configurable macro and reconfigurable logic domains can reveal strategic directions — and potential future assertion targets — for competitors and technology partners in the chip ecosystem.
AMD Qualcomm SoC IP strategyClaim space opened by cancellation of US6765407B1
The cancellation of US6765407B1 removes a set of claims from the active patent landscape in digital configurable macro architecture. For R&D teams with novel innovations in this domain — including next-generation programmable logic blocks, reconfigurable DSP macros, or adaptive SoC fabric designs — this creates potential white space adjacent to the cancelled claims that may now be claimable without prior art collision from this family.

What this case signals for the semiconductor IP landscape
The Federal Circuit's affirmance of unpatentability in Monterey Research v. AMD & Qualcomm carries enforcement and portfolio strategy lessons for IP teams across the chip sector.
Legacy semiconductor architecture patents face a high Federal Circuit bar
The Federal Circuit's unambiguous affirmance of unpatentability for US6765407B1 reinforces that older semiconductor architecture claims — particularly those filed around early 2000s application dates — are vulnerable to validity challenges. IP teams should audit portfolio assets in this vintage before relying on them for enforcement.
AMD and Qualcomm's successful defence clears their digital macro architecture pipeline
Both defendants now hold a Federal Circuit-confirmed invalidity shield against this patent. Teams working on configurable macro or SoC architecture designs adjacent to the cancelled claims can proceed with reduced IP litigation risk from this specific asset, though independent FTO analysis remains advisable for any related live patents.
Monterey v Advanced — key questions answered
The Federal Circuit affirmed the unpatentability determination in Case No. 22-1430, ordering and adjudging the lower ruling AFFIRMED on 13 October 2023. The recorded basis of termination is 'Unpatentable', confirming that US6765407B1's claims did not survive the patentability challenge brought by AMD and Qualcomm.
US6765407B1, filed under application number US10/272231, covers digital configurable macro architecture — programmable or reconfigurable functional blocks used in semiconductor integrated circuit design. This technology is commercially relevant to AMD's and Qualcomm's processor and SoC product lines, making them natural targets for assertion by Monterey Research, a patent assertion entity.
A Federal Circuit affirmance of unpatentability means the patent's claims are cancelled and unenforceable. Monterey Research cannot assert US6765407B1 against AMD, Qualcomm, or any other party going forward. The ruling is final at the Federal Circuit level; only a petition to the US Supreme Court would remain as a theoretical further avenue.
The appeal was filed on 2 February 2022 and closed on 13 October 2023, a duration of 618 days. This timeline is consistent with typical Federal Circuit patent appeal proceedings, which commonly run between 18 and 24 months from docketing to decision.
The unpatentability ruling in Case No. 22-1430 applies specifically to US6765407B1. The effect on any other patents held by Monterey Research depends on their individual claim scope and validity status, which are not addressed in this proceeding. Companies in the semiconductor space should conduct independent portfolio analysis to identify any remaining live Monterey Research assets that could support future assertion campaigns.
