Qualcomm v. Intel (22-1828): Federal Circuit Affirms in Part on Power Tracker Patent
Qualcomm and Intel clashed at the Federal Circuit over the validity of US9608675B2, a patent covering power tracker technology for multiple simultaneous transmit signals — a core component in modern multi-band wireless chipsets. The court issued a split decision, affirming in part and dismissing in part, after 851 days of appellate proceedings.
Qualcomm–Intel power tracker patent dispute reaches split Federal Circuit outcome
Filed on 26 May 2022, Case 22-1828 brought Qualcomm, Inc. as appellant before the Court of Appeals for the Federal Circuit against Intel Corp., challenging an earlier invalidity or cancellation determination concerning US9608675B2. The patent-in-suit claims power tracking technology designed to manage multiple transmit signals sent simultaneously — a capability central to carrier aggregation and multi-antenna transmission architectures used in 4G and 5G chipsets.
The Federal Circuit closed the case on 23 September 2024 with a verdict of ‘Affirmed in Part and Dismissed in Part,’ with the basis of termination recorded as ‘Appeal Dismissed in Part.’ This split disposition means the lower tribunal’s findings on certain claims or grounds were upheld on the merits, while other aspects of Qualcomm’s appeal were dismissed — most likely on procedural or jurisdictional grounds — without reaching the merits of those specific arguments.
An 851-day appellate duration suggests substantive briefing complexity, possibly including supplemental authority exchanges or coordination with parallel IPR proceedings. The public record does not specify which claim groupings were affirmed versus dismissed, nor whether any claims survive for enforcement purposes. Parties operating in the multi-carrier power management space should monitor any subsequent district court activity or reexamination proceedings that may follow from this outcome.

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 ‘Affirmed in Part’ ruling signals that the Federal Circuit found no reversible error in the tribunal below with respect to at least some of the challenged claims or grounds — those portions of the lower decision stand as binding. The ‘Dismissed in Part’ component indicates that certain appeal grounds were not decided on the merits, typically because the appellant lacked standing, the issue was moot, or the procedural prerequisites for review were not met.
Split appellate dispositionQualcomm’s patent faces a weakened but not fully extinguished position
Where the Federal Circuit affirmed the lower tribunal, Qualcomm’s challenges to those invalidity findings were rejected — meaning those claims or grounds remain cancelled or invalidated as determined below. The dismissed portion offers no merits-based relief for Qualcomm on those issues. Overall enforceability of US9608675B2 is likely reduced, though the precise scope of surviving claims, if any, is not determinable from the public appellate record alone.
Enforceability risk elevatedIntel secures partial validation of its invalidity challenge
Intel benefits from affirmance on the merits of at least some of its invalidity positions, providing a stronger defensive posture in any ongoing or future licensing dispute with Qualcomm over this patent family. The dismissed portions do not constitute Intel wins on the merits but do close off those appeal vectors for Qualcomm. Intel’s appellate options at this level are effectively exhausted on the affirmed grounds; further review would require Supreme Court certiorari.
Defensive position strengthenedPower tracker IP landscape shifts following partial affirmance
This outcome suggests that at least some of Qualcomm’s claimed power tracking inventions for simultaneous multi-signal transmission were found vulnerable to invalidity challenge. Competitors and licensees in the carrier-aggregation and multi-band chipset space may now have greater freedom-to-operate arguments against the affirmed-invalid claims. However, related patents in Qualcomm’s broader power management portfolio may still pose licensing exposure, and an FTO review against the surviving claim scope remains advisable.

Official order — verbatim text
The verdict phrasing ‘Affirmed in Part and Dismissed in Part’ is analytically significant. At the Federal Circuit, affirmance applies the substantial-evidence standard to PTAB factual findings and de novo review to legal conclusions such as claim construction. The partial affirmance binds the parties on those grounds with the force of a final appellate judgment. The ‘Dismissed in Part’ component — consistent with the recorded basis of termination — indicates that Qualcomm lacked standing or the predicate for review on the remaining appeal grounds, leaving the lower ruling undisturbed on those issues without merits adjudication.
US9608675B2 — Power tracker for multiple simultaneous transmit signals
US9608675B2, filed under application number US13/764328, protects power tracking circuitry and methods for handling multiple transmit signals sent simultaneously — a capability directly enabling carrier aggregation and MIMO transmission in LTE-Advanced and 5G NR platforms. The patent’s technical contribution centres on coordinating power envelope management across concurrent signal paths, reducing amplifier distortion and improving spectral efficiency in multi-band radio front-end architectures.
For the wireless chipset sector, this patent sits at the intersection of RF power efficiency and multi-band scalability — two commercially critical parameters for smartphone SoC and modem design. Qualcomm’s assertion of this patent against Intel, a direct competitor in baseband and platform solutions, underscores the strategic value of power management IP as a competitive differentiator. The partial invalidation outcome may modestly reduce Qualcomm’s licensing leverage on this specific asset, but related envelope-tracking and power control patents in the Qualcomm portfolio likely preserve broader coverage.
Should your team run an FTO against US9608675B2?
Any company designing or sourcing RF front-end modules, power amplifier management ICs, or baseband modem solutions that handle simultaneous multi-band or multi-carrier transmission should assess residual exposure to US9608675B2. The Federal Circuit’s partial affirmance of invalidity findings reduces — but does not eliminate — the risk that surviving claims could be asserted against carrier-aggregation-capable products. This applies to chipset vendors, OEMs incorporating third-party RF components, and infrastructure equipment manufacturers deploying multi-antenna architectures.

Qualcomm v Intel — key questions answered
The Federal Circuit issued a split decision — affirmed in part and dismissed in part — on 23 September 2024. The court upheld the lower tribunal’s invalidity findings on at least some grounds of US9608675B2 (power tracker for simultaneous multi-signal transmission) and dismissed the remaining appeal grounds, likely on procedural or jurisdictional bases rather than on the merits.
The patent at issue is US9608675B2, filed under application US13/764328. It protects power tracking technology for managing multiple transmit signals sent simultaneously, relevant to carrier aggregation and multi-band wireless transmission architectures used in LTE-Advanced and 5G NR chipsets.
At the Federal Circuit, ‘affirmed in part’ means the court found no reversible error in the lower tribunal’s decision on those specific grounds — those findings stand with binding appellate authority. ‘Dismissed in part’ means the court declined to reach the merits of the remaining appeal grounds, typically due to lack of standing, mootness, or failure to meet jurisdictional prerequisites, leaving those issues unresolved on substance.
Partially. Where the Federal Circuit affirmed invalidity findings, those claims of US9608675B2 are cancelled and no longer pose enforcement risk on that basis. However, the exact scope of surviving claims — if any — is not publicly detailed in the appellate record. Companies producing multi-carrier power management ICs or RF front-end modules should conduct a targeted FTO review against the full claim set and monitor related Qualcomm patents in the same family.
The appeal ran for 851 days, from filing on 26 May 2022 to closure on 23 September 2024. This is a notably extended timeline for a Federal Circuit patent validity appeal, suggesting complex briefing, possibly coordinated proceedings, or supplemental authority submissions. The average Federal Circuit appeal in PTAB-originated cases typically resolves within 18 to 24 months.
