Portfolio overview

Nippon Shokubai Co., Ltd. has been granted 277 US utility patents between 2015 and 2025, placing Nippon Shokubai Co., Ltd. at rank #1,502 across all assignees tracked by PlainPatent. This portfolio spans 98 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.8 claims per patent with primary concentration in C08F (MACROMOLECULAR COMPOUNDS OBTAINED BY REACTIONS ONLY INVOLVING CARBON-TO-CARBON UNSATURATED BONDS). As a Foreign Corporation, Nippon Shokubai Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Nippon sits between Rapid7, Inc. (278 patents, rank #1,498) and Fuji Jukogyo Kabushiki Kaisha (275 patents, rank #1,506) - the closest US assignees by grant volume. The composite Innovation Score of 55.5/100 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 123 grants, compared with 154 in the 2015–2019 window, a -20% 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. Nippon Shokubai Co., Ltd.'s 11.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 98 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nippon Shokubai Co., Ltd. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
