Portfolio overview

KEMIRA OYJ has been granted 230 US utility patents between 2015 and 2025, placing KEMIRA OYJ at rank #1,769 across all assignees tracked by PlainPatent. This portfolio spans 75 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.7 claims per patent with primary concentration in D21H (PULP COMPOSITIONS; PREPARATION THEREOF NOT COVERED BY SUBCLASSES D21C OR D21D; IMPREGNATING OR COATING OF PAPER; TREATMENT OF FINISHED PAPER NOT COVERED BY CLASS B31 OR SUBCLASS D21G; PAPER NOT OTHERW). As a Foreign Corporation, KEMIRA OYJ is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 59.9/100 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. Between 2020 and 2025 the company received 140 grants, compared with 90 in the 2015–2019 window — a +56% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. KEMIRA OYJ's 16.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 75 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark KEMIRA OYJ against peers pursuing similar technology classes.
