Portfolio overview
CMC Materials LLC has been granted 29 US utility patents between 2021 and 2025, placing CMC Materials LLC at rank #10,576 across all assignees tracked by PlainPatent. This portfolio spans 19 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.6 claims per patent with primary concentration in C09G (POLISHING COMPOSITIONS ; SKI WAXES). As a US Corporation, CMC Materials LLC is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 51.8/100 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 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. CMC Materials LLC's 15.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 19 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CMC Materials LLC against peers pursuing similar technology classes.
