Portfolio overview

NIPPON SOKEN, INC. has been granted 104 US utility patents between 2015 and 2021, placing NIPPON SOKEN, INC. at rank #3,537 across all assignees tracked by PlainPatent. This portfolio spans 74 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.3 claims per patent with primary concentration in Y02T (CLIMATE CHANGE MITIGATION TECHNOLOGIES RELATED TO TRANSPORTATION). As a Foreign Corporation, NIPPON SOKEN, INC. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 47.8/100 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 1 grants, compared with 103 in the 2015–2019 window — a -99% 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 SOKEN, INC.'s 11.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 74 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NIPPON SOKEN, INC. against peers pursuing similar technology classes.
