Portfolio overview
DORF KETAL CHEMICALS FZE has been granted 29 US utility patents between 2021 and 2025, placing DORF KETAL CHEMICALS FZE at rank #10,592 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.1 claims per patent with primary concentration in C09K (MATERIALS FOR MISCELLANEOUS APPLICATIONS, NOT PROVIDED FOR ELSEWHERE). As a Foreign Corporation, DORF KETAL CHEMICALS FZE is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 55.0/100 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 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. DORF KETAL CHEMICALS FZE's 11.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 22 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark DORF KETAL CHEMICALS FZE against peers pursuing similar technology classes.
