Case Overview
The Parties
⚖️ Plaintiff
Software company holding patents directed to electronic design automation (EDA) tooling methodologies—technologies used in semiconductor chip development.
🛡️ Defendant
Major U.S.-based semiconductor foundry and one of the world’s largest chip manufacturers, offering integrated process design kits and EDA-compatible open platform technologies.
Patents at Issue
This case centered on EDA software patents, which are critical to the design rule checking (DRC) and verification processes for semiconductor chip development. These patents are registered with the U.S. Patent and Trademark Office (USPTO).
- • US 7,685,545 — Software architectures for processing and verifying integrated circuit design data.
- • US 8,266,571 — Methodologies for normalizing, parsing, and digesting design rule data used in EDA workflows.
- • US 9,032,346 — (Also listed among patents of interest in the case record).

Litigation Timeline & Procedural History
Oasis Tooling filed its complaint on March 9, 2022, in the U.S. District Court for the District of Delaware—a preferred venue for patent litigation. A First Amended Complaint (D.I. 59) was subsequently filed, refining the asserted claims.
The case proceeded through standard district court litigation milestones over approximately 28 months, including discovery, motion practice, and claim construction proceedings. GlobalFoundries mounted a multi-front defense that ultimately crystallized into a Motion for Summary Judgment of Patent Ineligibility Under 35 U.S.C. § 101 (D.I. 493, 494).
On July 2, 2024, the court granted that motion in full. Final Judgment (D.I. 495) was entered on July 10, 2024, closing the case. All remaining motions were denied as moot, and GlobalFoundries’ remaining defenses and counterclaims—including its declaratory judgment counterclaims on invalidity—were dismissed without prejudice given the § 101 ruling fully resolved the dispute.
The Verdict & Legal Analysis
Outcome
The court entered final judgment of invalidity on all asserted claims of both the ‘545 and ‘571 patents on the ground of patent ineligibility under 35 U.S.C. § 101. GlobalFoundries prevailed on all counts. No damages were awarded to Oasis Tooling. No injunctive relief was issued. The case terminated at the district court level without trial.
§ 101 Eligibility Analysis
The § 101 ruling invokes the now-familiar two-step *Alice/Mayo* framework. Under *Alice Corp. v. CLS Bank International* (2014), software patent claims are ineligible if they are directed to an abstract idea and lack an “inventive concept” sufficient to transform that abstract idea into patent-eligible subject matter.
The asserted claims of the ‘545 and ‘571 patents—centered on parsing, normalizing, digesting, and reporting design rule data within an EDA software architecture—are precisely the type of functional software processes that courts have scrutinized intensely post-*Alice*. The court found that GlobalFoundries met its burden of demonstrating, as a matter of law, that the claimed methods were directed to abstract ideas without a sufficiently inventive application.
Legal Significance
This ruling reinforces several critical principles:
- • § 101 can terminate complex software patent cases before trial. Despite two-plus years of litigation, GlobalFoundries avoided trial entirely through a successful eligibility challenge.
- • EDA software patents face heightened § 101 scrutiny. Claims involving parsing, normalizing, and processing design rule data closely resemble abstract data manipulation—a recurring § 101 problem area.
- • Declaratory judgment counterclaims on invalidity were rendered moot, demonstrating that § 101 rulings can be outcome-dispositive even where other validity grounds (§ 102, § 103, § 112) exist.

Oasis Tooling asserted claims from U.S. Patent Nos. 7,685,545 and 8,266,571, covering EDA software architectures involving parsing, normalization, and design rule data processing. A third patent, U.S. Patent No. 9,032,346, also appeared in the case record.
The Delaware District Court granted GlobalFoundries’ Motion for Summary Judgment on July 2, 2024, finding all asserted patent claims ineligible under 35 U.S.C. § 101, applying the *Alice/Mayo* two-step framework for software patent eligibility.
The ruling reinforces that functional EDA software patents lacking concrete, non-abstract implementations face significant § 101 vulnerability. Patent holders in this space should reassess assertion strategies and prosecution approaches accordingly.
This ruling confirms that § 101 eligibility challenges remain a powerful and effective tool to terminate complex software patent cases, especially those involving abstract data processing steps, before reaching trial.
