Intel v. Qualcomm (22-1830): Federal Circuit Affirms Power Tracker Patent
Intel challenged Qualcomm’s US9608675B2 — a patent covering power tracking for multiple simultaneous transmit signals — at the Federal Circuit. After 851 days, the court affirmed in part and dismissed in part, leaving a significant portion of Qualcomm’s patent intact and enforceable.
Intel’s patentability challenge to Qualcomm’s RF power tracker partially survives appeal
Intel, Corp. filed this appeal at the Court of Appeals for the Federal Circuit on 26 May 2022, challenging a lower tribunal’s ruling on the patentability of Qualcomm’s US9608675B2. That patent protects power-tracking technology for multiple transmit signals sent simultaneously — a core capability in modern multi-carrier and MIMO wireless chipsets. Qualcomm defended both the validity of the patent and the correctness of the decision below, represented by Jones Day. Intel was represented by WilmerHale.
The Federal Circuit issued its disposition on 23 September 2024, affirming in part and dismissing in part. Affirmance means the court found no reversible error in the lower tribunal’s patentability analysis for the affirmed claims or issues; dismissal in part suggests one or more aspects of the appeal were terminated on procedural grounds without a merits ruling. The combined outcome leaves Qualcomm’s patent — or at least the affirmed portion of it — standing with the weight of appellate endorsement.
An 851-day appeal duration is consistent with a substantively contested inter partes review or related patentability proceeding reaching the Federal Circuit. The partial dismissal is notable: the public record does not specify which issues were dismissed or why, leaving open questions about Intel’s standing or the scope of claims actually adjudicated. What is clear is that Qualcomm’s power-tracker patent emerged from this proceeding with reinforced enforceability on the affirmed claims, raising the bar for any future validity challenge by Intel or third parties.

Federal Circuit affirms in part: what the split ruling means for both parties
What ‘Affirmed in Part, Dismissed in Part’ means at the Federal Circuit
‘Affirmed in part’ signals the Federal Circuit reviewed the lower tribunal’s patentability findings and found no reversible legal error on those issues — the decision below stands. ‘Dismissed in part’ means one or more of Intel’s appellate arguments or claim groups were terminated without a merits ruling, typically for lack of standing, mootness, or procedural deficiency. Together, they produce a split disposition that preserves the affirmed findings as binding precedent.
Partial affirmance + procedural dismissalQualcomm’s power tracker patent survives Federal Circuit scrutiny
For Qualcomm, the affirmance is a meaningful enforcement victory. US9608675B2’s patentability — on the affirmed claims — now carries the Federal Circuit’s imprimatur, making future invalidity challenges significantly harder to sustain. Licensees and competitors in the multi-carrier RF space face a strengthened patent. The partial dismissal does not undermine this: dismissed portions received no merits ruling that could benefit challengers.
Patent enforceability strengthenedIntel’s appellate options on affirmed claims are effectively exhausted
For Intel, the affirmance closes the Federal Circuit avenue on the decided issues. Further challenge would require a petition to the Supreme Court — an extremely high bar — or a new IPR based on different prior art not previously before the tribunal. The partial dismissal may preserve a narrow procedural door on the dismissed issues, but the public record does not confirm this. Intel’s ability to contest this patent in future licensing or litigation contexts is meaningfully constrained.
Appellate challenge largely exhaustedReinforced power-tracker IP raises licensing leverage in the RF chipset sector
US9608675B2 covers power tracking for multiple simultaneous transmit signals — a function central to LTE-A, 5G NR, and multi-SIM device architectures. With Federal Circuit affirmance, Qualcomm’s licensing position in negotiations with OEMs, chipset vendors, and device manufacturers is materially strengthened. Third parties designing multi-carrier RF front-end solutions should reassess freedom-to-operate exposure. The decision also suggests higher IPR success bars for similar power-management claims going forward.

Official order — verbatim text
The ‘Affirmed in Part and Dismissed in Part’ disposition is a split Federal Circuit outcome. Affirmance means the court applied its deferential review standard — finding no reversible legal error in the patentability determination below. The partial dismissal, without further specification in the public record, most likely reflects a procedural bar such as standing deficiency or mootness on specific claims rather than a merits ruling favourable to either party. Qualcomm retains enforceable claims; Intel’s challenge is substantially, though possibly not entirely, foreclosed.
US9608675B2 — Power Tracker for Multiple Simultaneous Transmit Signals
US9608675B2, filed under application number US13/764328, protects a power tracker architecture designed to manage power across multiple transmit signals sent simultaneously. This capability is technically demanding: in multi-carrier and MIMO configurations, independent transmit paths must be power-controlled in parallel without cross-interference. The patent addresses this challenge at the circuit or system level, placing it squarely within the RF front-end and baseband-modem technology domain central to LTE-Advanced and 5G standards.
Qualcomm’s ownership of this patent is strategically significant. Power management in multi-carrier chipsets is a cost, battery-life, and regulatory-compliance bottleneck for every OEM shipping smartphones, connected devices, or infrastructure equipment. A patent covering the power-tracker architecture for simultaneous multi-signal transmission gives Qualcomm leverage in standard-essential and non-essential licensing programmes alike. The Federal Circuit’s affirmance now makes this an anchor asset in Qualcomm’s RF IP portfolio — one that competitors and licensees must treat as high-validity.
Should your team run an FTO against US9608675B2?
Any organisation developing chipsets, RF front-end modules, or device architectures that support carrier aggregation, multi-SIM simultaneous transmission, or MIMO configurations should assess exposure to US9608675B2. The Federal Circuit’s partial affirmance means the patent’s core claims survived the highest validity review short of the Supreme Court. Wireless modem vendors, RF IC designers, and OEMs sourcing non-Qualcomm chipsets for 5G or LTE-A products are the highest-risk categories.

Federal Circuit affirmance raises the invalidity bar for power tracker claims
Any party seeking to challenge US9608675B2 now faces the added weight of appellate review. Invalidity arguments already considered below and affirmed cannot be relitigated. New IPR petitions would need materially different prior art to have a realistic chance — a higher strategic threshold for Intel and any third-party challengers.
OEMs and RF chipset vendors should re-examine FTO on multi-transmit power tracking
The affirmed claims define protected territory in multi-carrier simultaneous-transmit power management — directly relevant to 5G NR, LTE-A carrier aggregation, and multi-SIM products. Companies shipping devices or chipsets with these architectures should treat this decision as a trigger for a fresh FTO review against US9608675B2 and the broader Qualcomm power-management portfolio.
Intel v Qualcomm — key questions answered
The Federal Circuit affirmed in part and dismissed in part. The affirmance means the court found no reversible error in the patentability ruling on the decided issues relating to US9608675B2. The partial dismissal terminated one or more of Intel’s appellate arguments without a merits ruling, likely on procedural grounds. Qualcomm’s patent emerged with strengthened enforceability on the affirmed claims.
US9608675B2 protects a power tracker for multiple transmit signals sent simultaneously — a core function in multi-carrier LTE-A and 5G NR chipset architectures. Simultaneous multi-signal power tracking is essential for carrier aggregation and MIMO operation. Qualcomm’s ownership of this patent gives it licensing leverage over chipset vendors and OEMs shipping devices with these capabilities, making it a commercially significant asset in wireless IP portfolios.
‘Affirmed in part’ means the Federal Circuit reviewed the lower tribunal’s findings and found no reversible legal error — the decision stands on those issues. ‘Dismissed in part’ means one or more aspects of the appeal were ended without a merits ruling, often due to lack of standing, mootness, or procedural bars such as IPR estoppel. The combined outcome produces a split disposition where affirmed findings are binding and dismissed portions receive no merits adjudication.
On the affirmed issues, Intel’s options are substantially limited. A petition for certiorari to the Supreme Court is theoretically available but succeeds in fewer than 2% of petitions. A new IPR based on different prior art not previously before the tribunal remains a possibility in principle, though IPR estoppel may bar arguments Intel reasonably could have raised. The dismissed portion may preserve a narrow residual avenue, but the public record does not confirm this.
