Portfolio overview

F-star Therapeutics Limited has been granted 11 US utility patents between 2022 and 2025, placing F-star Therapeutics Limited at rank #24,309 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 21.6 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a Foreign Corporation, F-star Therapeutics Limited is one of the more focused assignees in the PatentsView dataset. By volume, F-star sits between Evolv Technologies, Inc. (11 patents, rank #24,305) and Finis Inc. (11 patents, rank #24,313) - the closest US assignees by grant volume. The composite Innovation Score of 50.9/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Historical data spans 2022 through 2025, with 11 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. F-star Therapeutics Limited's 21.6 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark F-star Therapeutics Limited against peers pursuing similar technology classes.
