Patent Armory v. AMD: Parallel Signal Processing Suit Dismissed With Prejudice in 170 Days
Patent Armory, Inc. asserted US10803883B1 — a parallel signal processing patent — against semiconductor giant Advanced Micro Devices in the Western District of Texas. The plaintiff voluntarily dismissed the action with prejudice just 170 days after filing, before AMD had filed any answer, with each party bearing its own costs.
Early voluntary exit in a parallel signal processing patent assertion against AMD
On September 6, 2023, Patent Armory, Inc. filed an infringement action against Advanced Micro Devices, Inc. (AMD) in the Western District of Texas — Case No. 6:23-cv-00650 — before Chief Judge Alan D. Albright. The sole patent asserted was US10803883B1, covering a parallel signal processing system and method. AMD is one of the world’s leading semiconductor designers, and the case was assigned to a court historically active in patent litigation.
The case closed on February 23, 2024 — just 170 days after filing — when Patent Armory filed a voluntary notice of dismissal with prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because AMD had not yet answered the complaint or moved for summary judgment at that point, the plaintiff was entitled to dismiss unilaterally without a court order. The with-prejudice designation means Patent Armory is permanently barred from reasserting the same claims against AMD on the same patent.
The resolution at the pre-answer stage is consistent with a pattern seen in patent assertion entity litigation where early settlement or licensing negotiations — rather than full merits adjudication — drive outcomes. The public record does not disclose whether any licensing agreement was reached between the parties; the terms of any such arrangement, if one exists, remain confidential. What is clear is that AMD avoided any public admission of infringement and faces no ongoing liability on this patent from this plaintiff.

Voluntary dismissal with prejudice under FRCP 41(a)(1)(A)(i) — what it means
FRCP 41(a)(1)(A)(i): unilateral dismissal before defendant answers
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice of dismissal before the defendant serves an answer or a motion for summary judgment. AMD had done neither at the time of dismissal, making Patent Armory’s notice legally self-executing. No judicial approval was required or sought.
Self-executing notice — no court order neededWith prejudice: Patent Armory’s claims against AMD are permanently closed
A dismissal with prejudice operates as a final adjudication on the merits — Patent Armory cannot refile the same infringement claims against AMD based on US10803883B1. This contrasts with a dismissal without prejudice, which would preserve the right to refile. By choosing the with-prejudice designation, the plaintiff accepted a permanent bar, suggesting the dispute has been fully resolved between the parties.
Permanent bar on refilingEach party bears its own costs — no fee-shifting under § 285
The dismissal notice stipulates that each party shall bear its own costs, expenses, and attorneys’ fees. In patent cases, fee-shifting under 35 U.S.C. § 285 is available in ‘exceptional cases,’ but no such motion was brought here. The mutual cost-bearing arrangement is typical of negotiated early exits and avoids any public finding of bad faith or frivolous assertion.
No § 285 exceptional case findingDismissal before AMD’s answer limits public record of the dispute
Because the case resolved before AMD filed any responsive pleading, no invalidity arguments, non-infringement positions, or claim constructions entered the public record. This is strategically significant: AMD’s legal theories regarding US10803883B1 remain undisclosed, and there is no court ruling on the patent’s validity or scope that third parties can rely upon.

Stipulation of dismissal — official text
The dismissal notice invokes FRCP 41(a)(1)(A)(i), which permits a plaintiff to dismiss unilaterally before a defendant answers. Patent Armory’s choice of the with-prejudice designation is the critical operative term: it permanently extinguishes all asserted claims against AMD arising from this action. For AMD, the outcome provides full closure with no admission of infringement and no legal costs order. For Patent Armory, the trade-off is the permanent surrender of litigation leverage against AMD on this patent.
US10803883B1 — Parallel Signal Processing System and Method
US10803883B1 (application no. US16/186252) is a US utility patent granted to Patent Armory, Inc. covering a parallel signal processing system and method. The patent sits at the intersection of digital signal processing architecture and parallel computation — technology domains that are foundational to modern CPU, GPU, and DSP design. The parallel processing techniques claimed are relevant to how chips decompose and execute signal workloads across multiple processing units simultaneously, a capability central to high-performance computing and AI acceleration.
The patent’s assertion against AMD — whose core business involves designing processors that execute parallel workloads — suggests the claims may read on architectures or methods used in mainstream semiconductor products. For other chip designers, GPU vendors, and DSP manufacturers, the continued validity and enforceability of US10803883B1 represents a live risk. Patent assertion entities holding such patents have demonstrated willingness to pursue licensing campaigns across an industry vertical, making this patent a candidate for proactive monitoring by any company active in parallel signal processing.
Should your team run an FTO against US10803883B1?
If your company designs, manufactures, or sells products that perform parallel signal processing — including GPUs, DSPs, FPGAs, AI accelerators, or multi-core signal processing pipelines — US10803883B1 warrants direct attention. This patent has already been asserted against one of the world’s largest chip designers. The dismissal with prejudice only protects AMD; every other market participant remains fully exposed to assertion by Patent Armory.

What this case signals for the semiconductor and signal processing IP landscape
A fast pre-answer exit by a patent assertion entity against AMD raises pointed questions about assertion strategy and licensing leverage in the chip sector.
Pre-answer dismissal with prejudice often signals a concluded licensing negotiation
When a plaintiff voluntarily exits with prejudice before any substantive court filings, and the defendant is a well-resourced company like AMD, the pattern is consistent with a confidential licensing or settlement agreement. The with-prejudice designation provides AMD with certainty that this specific claim is extinguished, which is a condition typically demanded in licensing resolutions.
AMD’s legal strategy on this patent remains entirely undisclosed
No answer, IPR petition, or claim construction brief was filed. Companies operating in the parallel signal processing space cannot rely on any public AMD non-infringement or invalidity argument from this case. Any FTO assessment relative to US10803883B1 must be conducted independently — this docket provides no defensive prior art or claim scope analysis to leverage.
