Portfolio overview

C4 THERAPEUTICS, INC. has been granted 29 US utility patents between 2020 and 2025, placing C4 THERAPEUTICS, INC. at rank #10,568 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.9 claims per patent with primary concentration in C07D (HETEROCYCLIC COMPOUNDS). As a US Corporation, C4 THERAPEUTICS, INC. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 52.9/100 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 2020 through 2025, with 29 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The US 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. C4 THERAPEUTICS, INC.'s 20.9 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark C4 THERAPEUTICS, INC. against peers pursuing similar technology classes.
