Portfolio overview

Nippon Kayaku Kabushiki Kaisha has been granted 201 US utility patents between 2015 and 2025, placing Nippon Kayaku Kabushiki Kaisha at rank #1,992 across all assignees tracked by PlainPatent. This portfolio spans 67 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.2 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, Nippon Kayaku Kabushiki Kaisha is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Nippon sits between Tokuyama Corporation (202 patents, rank #1,988) and Valve Corporation (201 patents, rank #1,996) - the closest US assignees by grant volume. The composite Innovation Score of 54.9/100 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 101 grants, compared with 100 in the 2015–2019 window, a +1% 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. Nippon Kayaku Kabushiki Kaisha's 11.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 67 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nippon Kayaku Kabushiki Kaisha against peers pursuing similar technology classes.
