Qualcomm v. Intel: Federal Circuit Affirms in Part on Power Tracker Patent
Qualcomm appealed an invalidity/cancellation action brought by Intel over US9608675B2, a patent covering power tracker technology for multiple simultaneous transmit signals. The Federal Circuit returned a split ruling — affirming in part and dismissing in part — after 851 days of appellate proceedings.
A split Federal Circuit ruling in a high-stakes Qualcomm–Intel patent dispute
Filed on 26 May 2022, Case No. 22-1826 pits semiconductor giants Qualcomm, Inc. against Intel Corp. before the Court of Appeals for the Federal Circuit. At issue is US9608675B2 — a Qualcomm patent covering power tracker technology designed to manage multiple transmit signals sent simultaneously, a capability central to modern multi-band wireless communications. Intel had pursued an invalidity or cancellation action at the trial level, challenging the patentability of Qualcomm’s claimed technology.
The Federal Circuit issued a verdict of ‘Affirmed in Part and Dismissed in Part’ on 23 September 2024. The affirmance component means the court found no reversible error in the lower tribunal’s decision with respect to those issues it addressed on the merits. The dismissal-in-part component indicates that certain aspects of Qualcomm’s appeal were terminated without a merits ruling — typically for procedural reasons such as lack of standing or jurisdiction over those specific issues.
The 851-day duration is notably longer than the typical Federal Circuit patent appeal, suggesting substantive complexity in the patentability arguments and potentially contested procedural questions around appellate standing. The split outcome — partial affirmance alongside partial dismissal — is analytically significant: it prevents either party from claiming a clean win and leaves portions of the underlying dispute’s legal landscape unsettled. The precise scope of what was affirmed versus dismissed is not fully detailed in the public record, warranting close review of the full opinion.

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 that the Federal Circuit reviewed the merits of certain issues and found no reversible error in the lower tribunal’s decision — those rulings stand. ‘Dismissed in Part’ means the court declined to reach the merits of remaining issues, likely due to procedural barriers such as lack of appellate standing, mootness, or jurisdictional deficiency. Together, the split verdict reflects a court that validated some outcomes below while closing off other appellate avenues entirely.
Partial merits reviewQualcomm’s power tracker patent survives — but not on all fronts
For Qualcomm, the affirmance component preserves the patentability determinations upheld below on the issues the Federal Circuit addressed. US9608675B2 retains enforceability to the extent those affirmed claims remain valid. However, the partial dismissal suggests Qualcomm could not sustain an appellate challenge on all grounds it raised, limiting the full scope of relief it sought. The patent’s commercial value in licensing negotiations and enforcement actions is partially, but not wholly, reinforced by this outcome.
Partial patent survivalIntel avoids full reversal, but the affirmed claims remain a licensing risk
Intel’s invalidity/cancellation challenge succeeded in part — the dismissal of portions of Qualcomm’s appeal effectively ends those issues in Intel’s favour without the Federal Circuit ruling against it on the merits. However, the affirmance of lower-level findings against Intel on the remaining issues means that the claims upheld below continue to stand, potentially sustaining Qualcomm’s leverage in any ongoing licensing or enforcement context. Intel’s appellate options on the affirmed portion are now exhausted at the Federal Circuit level.
Challenge partially successfulPower management IP in wireless remains contested territory post-ruling
A split affirmance in a Qualcomm–Intel dispute over power tracker technology signals that multi-transmit power management patents remain viable enforcement assets, even under aggressive invalidity challenge. For chipmakers and wireless device OEMs operating in the multi-band RF space, the survival of core claims in US9608675B2 elevates the FTO risk profile for competing power tracker architectures. The outcome also suggests that procedural strategy — specifically, which claims are appealed and on what basis — is as critical as substantive patentability arguments at this level.

Official order — verbatim text
The Federal Circuit’s verdict of ‘Affirmed in Part and Dismissed in Part’ reflects a bifurcated appellate review. On the affirmed issues, the court applied its standard of review — likely de novo for legal questions of patentability and clear error for underlying factual findings — and found no reversible error in the lower tribunal’s determination. The dismissal-in-part, by contrast, carries no merits weight: those issues were terminated for procedural reasons, most commonly lack of appellate standing under the doctrine elaborated in cases like JTEKT Corp. v. GKN Automotive. The net effect is that Intel’s cancellation success below is partially preserved, while Qualcomm retains enforceability of the affirmed claims.
US9608675B2 — Power Tracker for Multiple Simultaneous Transmit Signals
US9608675B2, filed under application number US13/764328, protects power tracker technology enabling a single device to manage power envelopes across multiple transmit signals sent simultaneously. This is foundational to carrier aggregation and multi-band LTE/5G implementations where power efficiency and signal fidelity must be maintained in parallel across frequency bands. The patent sits within Qualcomm’s RF front-end portfolio — a strategically critical domain as wireless standards demand ever-higher spectral efficiency.
Power management IP of this type is commercially significant because it underpins chipset design decisions for handset OEMs, base station manufacturers, and IoT device makers. Qualcomm’s enforcement of US9608675B2 against Intel — a direct competitor in the modem and RF chipset space — signals that power tracker architecture is an active battleground. Any party designing multi-carrier transmit chains, envelope tracking modules, or digital pre-distortion systems should treat this patent family as a freedom-to-operate priority.
Should your team run an FTO analysis against US9608675B2?
If your organisation designs or sources chipsets, RF front-end modules, or transceiver architectures incorporating simultaneous multi-band transmission, US9608675B2 presents a live FTO concern. The Federal Circuit’s partial affirmance means that at least a subset of claims survived rigorous invalidity scrutiny — those claims are presumed valid and enforceable. This is particularly relevant for modem designers, envelope tracking suppliers, and OEMs integrating multi-carrier aggregation features into consumer or industrial wireless devices.

What this case signals for the semiconductor and wireless IP landscape
A Federal Circuit split verdict between Qualcomm and Intel over power tracker technology carries broad implications for RF chipset IP strategy.
Power tracker patents remain enforceable assets after Federal Circuit review
The partial affirmance confirms that US9608675B2’s core claims withstood a sophisticated invalidity challenge from Intel. Companies developing multi-band transmitter architectures should treat surviving Qualcomm power tracker claims as live licensing risks, not neutralised prior art.
Procedural standing matters as much as substantive arguments on appeal
The dismissal-in-part component suggests that Qualcomm was unable to sustain appellate standing or jurisdiction on certain claims. This is a recurring Federal Circuit dynamic in IPR appeals: challengers and patent holders alike must carefully audit which grounds survive the standing threshold before committing appellate resources.
Qualcomm v Intel — key questions answered
The Federal Circuit issued a verdict of ‘Affirmed in Part and Dismissed in Part’ on 23 September 2024. The affirmance upheld the lower tribunal’s findings on certain patentability issues without reversible error. The dismissal-in-part terminated remaining appeal grounds without merits review, likely for procedural or standing reasons.
The patent at issue is US9608675B2, filed under application US13/764328. It covers power tracker technology for managing multiple transmit signals sent simultaneously — a core capability in carrier aggregation and multi-band wireless communications systems, including LTE and 5G chipsets.
At the Federal Circuit, ‘Affirmed in Part’ means the court reviewed the merits and found no reversible error in the lower decision for those issues. ‘Dismissed in Part’ means the court declined to reach the merits on remaining issues — typically because the appellant lacked standing, the issue was moot, or the court lacked jurisdiction. The split outcome means neither party achieved a clean appellate win.
The partial affirmance supports ongoing enforceability of the claims upheld by the lower tribunal on the affirmed issues. Qualcomm retains the ability to assert those claims in licensing negotiations and enforcement actions. The partial dismissal limits the scope of full relief Qualcomm sought but does not invalidate the affirmed claims.
