Portfolio overview

KYOWA HAKKO KIRIN CO., LTD. has been granted 112 US utility patents between 2015 and 2021, placing KYOWA HAKKO KIRIN CO., LTD. at rank #3,328 across all assignees tracked by PlainPatent. This portfolio spans 23 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.8 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a Foreign Corporation, KYOWA HAKKO KIRIN CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 40.9/100 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 3 grants, compared with 109 in the 2015–2019 window — a -97% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. KYOWA HAKKO KIRIN CO., LTD.'s 12.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 23 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark KYOWA HAKKO KIRIN CO., LTD. against peers pursuing similar technology classes.
