Portfolio overview

Checkerspot, Inc. has been granted 10 US utility patents between 2021 and 2025, placing Checkerspot, Inc. at rank #26,034 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 29.8 claims per patent with primary concentration in C08G (MACROMOLECULAR COMPOUNDS OBTAINED OTHERWISE THAN BY REACTIONS ONLY INVOLVING UNSATURATED CARBON-TO-CARBON BONDS). As a US Corporation, Checkerspot, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Checkerspot sits between Chagrinovations, Llc (10 patents, rank #26,030) and Chronix Biomedical (10 patents, rank #26,038) - the closest US assignees by grant volume. The composite Innovation Score of 57.9/100 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 2021 through 2025, with 10 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. Checkerspot, Inc.'s 29.8 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Checkerspot, Inc. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
