Aperçu du dossier

In a decisive ruling from the Western District of Texas, Judge Alan D. Albright dismissed Daedalus Prime, LLC’s patent infringement complaint against Marvell Technology, Inc., closing Case No. 7:25-cv-00413 just 128 days after filing. The court found that Daedalus Prime failed to adequately plead how the accused Octeon 10 microprocessor products satisfied key claim limitations — a pleading deficiency that proved fatal to at least one central infringement count and ultimately to the entire complaint.

The case centered on six U.S. patents spanning memory management, processing architecture, and power optimization technologies, all asserted against Marvell’s commercially significant Octeon 10 processor family. For patent litigators and in-house IP counsel tracking **microprocessor patent infringement** trends in Texas federal courts, this outcome underscores a critical and recurring lesson: asserting patent infringement without sufficiently addressing *how* each functional limitation is met invites early dismissal, regardless of the underlying technology’s merit.

Les parties

Brevets en cause

This case involved six U.S. patents covering fundamental microprocessor technologies, all asserted against Marvell’s Octeon 10 family of products. These patents collectively cover technical areas including cache memory architecture, processor power states, and data processing optimization.

• • US10705960B2 — Cache memory architecture
• • US8984228B2 — Data processing optimization
• • US8769316B2 — Processor power states
• • US10725919B2 — Cache management
• • US10372197B2 — Multiprocessor systems
• • US8775833B2 — Memory access control

Le verdict et l'analyse juridique

Résultat

The court **dismissed Daedalus Prime’s complaint in its entirety**, with specific reasoning articulated around Count 6 — the direct infringement claim concerning the **’228 Patent (US8984228B2)**. No damages were awarded, and no injunctive relief was granted. The basis of termination was a failure to adequately plead direct infringement.

Principales questions juridiques

The court’s dismissal language is instructive and worth examining closely:

“Because Plaintiff fails to address how the limitation’s functionality is met, the Court should dismiss Plaintiff’s claim for direct infringement of the ‘228 Patent (Count 6).”

This ruling turns on a fundamental pleading requirement in patent cases: a complaint must do more than identify an accused product and cite a patent. It must plausibly allege *how* each claim element — particularly functional limitations — is satisfied by the accused product. The court cited two key precedents, ***CPC*, 2022 WL 118955, at *2** and ***De La Vega*, 2020 WL 3528411, at *6**, reinforcing the requirement for functional limitation mapping and addressing the sufficiency threshold for direct infringement pleading.

The failure was not merely technical. Functional limitations in microprocessor patents require careful, element-by-element analysis tying the patent claim language to specific operational features of the accused product. Daedalus Prime’s complaint apparently did not supply this mapping with sufficient specificity for at least one claim — and the deficiency was broad enough to support dismissal of the full complaint.
