Portfolio overview
NIHON PLAST CO., LTD. has been granted 80 US utility patents between 2015 and 2025, placing NIHON PLAST CO., LTD. at rank #4,424 across all assignees tracked by PlainPatent. This portfolio spans 31 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.0 claims per patent with primary concentration in B60R (VEHICLES, VEHICLE FITTINGS, OR VEHICLE PARTS, NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, NIHON PLAST CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 43.4/100 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 31 grants, compared with 49 in the 2015–2019 window — a -37% 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. NIHON PLAST CO., LTD.'s 5.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 31 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NIHON PLAST CO., LTD. against peers pursuing similar technology classes.
