Intel v. Qualcomm (22-1829): Federal Circuit Affirms Power Tracker Patent in Part
Intel challenged the validity of Qualcomm’s US9608675B2 — a patent covering power tracking for multiple simultaneous transmit signals — before the Federal Circuit. After 851 days, the court affirmed in part and dismissed the remaining appeal in part, leaving core claims of Qualcomm’s patent intact.
Federal Circuit splits outcome in Intel–Qualcomm power-tracker appeal
Intel Corporation filed this appeal at the Court of Appeals for the Federal Circuit on 26 May 2022, targeting Qualcomm’s US9608675B2 — a patent protecting power-tracking architecture for multiple transmit signals sent simultaneously. The underlying dispute concerned patentability, specifically an invalidity or cancellation challenge to Qualcomm’s claims. The technology sits at the core of modern multi-carrier and carrier-aggregation chipset design, an area where the two companies have long been commercial rivals.
On 23 September 2024, after 851 days, the Federal Circuit issued a split disposition: affirmed in part and dismissed in part. The affirmance means the court found no reversible error in the lower tribunal’s decision upholding the challenged claims, leaving those claims valid and enforceable. The partial dismissal — consistent with the basis of termination noting ‘Appeal Dismissed in Part’ — suggests that one or more grounds of Intel’s challenge were disposed of on procedural or jurisdictional grounds rather than on the merits.
An 851-day appellate timeline is notable but not unusual for contested patentability appeals at the Federal Circuit involving complex semiconductor IP. The split outcome suggests Intel succeeded in eliminating at least some appellate footing, while Qualcomm preserved enforceability of the affirmed claims. What specific claim subsets were affirmed versus dismissed, and the precise procedural basis for dismissal of the remaining portion, are not detailed in the public docket record reviewed here.

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
An appellate affirmance signals that the Federal Circuit found no reversible error in the lower tribunal’s decision on those claims — the challenged patent claims survive and remain valid. The partial dismissal indicates the court declined to reach the merits of at least one element of Intel’s challenge, most likely for lack of standing, jurisdiction, or procedural defect on that portion. No new merits ruling was made on the dismissed portion.
Split appellate dispositionQualcomm’s power tracker claims survive Federal Circuit scrutiny
The affirmance is a meaningful win for Qualcomm: the Federal Circuit’s imprimatur reinforces enforceability of the affirmed claims in US9608675B2. Patent holders typically gain negotiating leverage in licensing discussions after a successful appellate defence. For Qualcomm, whose licensing revenue is closely tied to the validity of its core wireless IP, preserving these claims forecloses one significant avenue of invalidity attack by a major competitor.
Patent enforceability strengthenedIntel’s invalidity challenge fails on the merits for affirmed claims
For Intel, the affirmance exhausts appellate options at this level for the claims that were reviewed on the merits. A petition for certiorari to the Supreme Court remains theoretically available but is rarely granted in patent validity cases absent a circuit split. The partial dismissal, while procedurally neutral on merits, still leaves Intel facing enforceable Qualcomm claims covering power-tracking technology relevant to multi-carrier chip design.
Appellate challenge largely unsuccessfulAffirmed power-tracker claims raise the bar for future challenges
For the broader semiconductor and wireless chipset sector, this outcome signals that Qualcomm’s power-management IP for simultaneous multi-signal transmission has withstood rigorous post-grant and appellate scrutiny. Competitors designing carrier-aggregation or multi-antenna transmit architectures should treat the affirmed claims as a credible enforcement risk. Future IPR petitions against the same claims face a higher estoppel and prior-art bar given the Federal Circuit’s affirmance.

Official order — verbatim text
The verdict phrase ‘AFFIRMED IN PART AND DISMISSED IN PART’ reflects a split appellate disposition. On the affirmed portion, the Federal Circuit applied its standard review framework — de novo for claim construction and legal conclusions, substantial-evidence deference for underlying factual determinations — and found the lower tribunal committed no reversible error. The dismissal in part, by contrast, indicates the court declined jurisdiction or found a procedural bar on at least one element of Intel’s challenge, leaving those grounds unresolved on the merits. The net effect is that the affirmed claims of US9608675B2 carry heightened presumptive validity going forward.
US9608675B2 — Power tracker for multiple simultaneous transmit signals
US9608675B2 (application number US13/764328) protects power-tracking technology for multiple transmit signals sent simultaneously — a critical function in LTE Advanced and 5G chipsets that use carrier aggregation or multi-antenna transmission. Power tracker circuits must manage envelope-tracking or average-power-tracking across concurrent signal paths to maintain efficiency and regulatory compliance. The patent’s application date places its priority in the early carrier-aggregation era, making it foundational rather than incremental.
For the semiconductor and wireless ecosystem, this patent occupies strategically important ground. Multi-signal simultaneous transmission is a baseline requirement for any modern handset or base-station chipset supporting carrier aggregation, and power management efficiency directly affects battery life and thermal performance. Qualcomm’s ownership of hardened IP in this space — now further reinforced by Federal Circuit affirmance — creates meaningful licensing leverage over chipset designers, OEMs, and network equipment vendors who implement comparable power-tracking architectures.
Should your team run an FTO against US9608675B2?
Any R&D team or product group designing power-tracking, envelope-tracking, or average-power-tracking circuits for multi-carrier or simultaneous multi-signal wireless chipsets should treat US9608675B2 as a live enforcement risk. The Federal Circuit’s affirmance means the patent has survived a direct invalidity challenge brought by one of the industry’s most well-resourced challengers. Device OEMs, chipset vendors, and RF front-end module designers operating in LTE-A or 5G carrier-aggregation space are the most directly exposed.

What this case signals for the wireless semiconductor IP landscape
The Intel–Qualcomm power-tracker outcome reinforces Qualcomm’s patent fortress around multi-signal transmission and raises costs for competitors seeking invalidity routes.
Partial dismissal creates ambiguity that rivals can probe
The Federal Circuit’s split disposition — affirming some claims but dismissing others without merits review — leaves open questions about the procedural basis for dismissal. Competitors and licensees should analyse which specific claims were affirmed versus dismissed, as the dismissed portion may not carry the same estoppel weight and could be revisited through alternative IPR or ex parte reexamination strategies.
Power-tracking architecture is now hardened IP for Qualcomm licensing
US9608675B2 covers power tracking for simultaneous multi-signal transmission — a foundational function in modern LTE and 5G carrier-aggregation chipsets. With Federal Circuit affirmance behind it, Qualcomm can deploy this patent more confidently in licensing negotiations and enforcement actions against chipset makers and device OEMs operating in the same technical space.
Intel v Qualcomm — key questions answered
The Federal Circuit affirmed in part and dismissed in part Intel’s appeal challenging the validity of Qualcomm’s US9608675B2, a patent covering power tracking for multiple simultaneous transmit signals. The affirmance means the court found no reversible error in upholding those claims; the partial dismissal disposed of at least one element of Intel’s challenge on procedural grounds without reaching the merits. The case closed on 23 September 2024 after 851 days.
US9608675B2 covers power-tracking architecture for multiple transmit signals sent simultaneously — a function essential to carrier-aggregation and multi-antenna transmission in LTE Advanced and 5G chipsets. Power tracker circuits in this context manage the power envelope across concurrent signal paths to maintain efficiency and meet regulatory output requirements. The patent was filed under application number US13/764328.
The Federal Circuit affirmance confirms that the lower tribunal’s decision upholding the challenged claims was free from reversible error, reinforcing the presumptive validity of those claims. Qualcomm can leverage this appellate record in future licensing negotiations and enforcement actions. The partial dismissal on procedural grounds does not undermine the affirmed claims, though the dismissed grounds may carry different estoppel consequences than a full merits affirmance.
Following a Federal Circuit affirmance, Intel’s options are significantly narrowed. A petition for certiorari to the US Supreme Court is theoretically available but rarely granted in patent validity disputes absent a circuit split. For the dismissed portion, the absence of a merits ruling means estoppel may be less absolute, potentially leaving room for alternative IPR or ex parte reexamination routes depending on the procedural basis for dismissal. Specific strategy would require detailed claim-level analysis.
Intel was represented by Wilmer Cutler Pickering Hale and Dorr LLP, with David Langdon Cavanaugh listed as counsel. Qualcomm was represented by Jones Day, with Matthew Johnson as counsel of record. Both firms have deep Federal Circuit patent appellate practices, consistent with the high-stakes nature of a semiconductor IP validity challenge between two major industry players.
