Portfolio overview

KYORAKU CO., LTD. has been granted 150 US utility patents between 2015 and 2025, placing KYORAKU CO., LTD. at rank #2,592 across all assignees tracked by PlainPatent. This portfolio spans 61 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.4 claims per patent with primary concentration in B29C (SHAPING OR JOINING OF PLASTICS; SHAPING OF MATERIAL IN A PLASTIC STATE, NOT OTHERWISE PROVIDED FOR; AFTER-TREATMENT OF THE SHAPED PRODUCTS, e.g. REPAIRING). As a Foreign Corporation, KYORAKU CO., LTD. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 51.6/100 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 88 grants, compared with 62 in the 2015–2019 window — a +42% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. KYORAKU CO., LTD.'s 8.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 61 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark KYORAKU CO., LTD. against peers pursuing similar technology classes.
