Portfolio overview
NISSEI PLASTIC INDUSTRIAL CO., LTD. has been granted 52 US utility patents between 2015 and 2025, placing NISSEI PLASTIC INDUSTRIAL CO., LTD. at rank #6,473 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.0 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, NISSEI PLASTIC INDUSTRIAL CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 46.9/100 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 26 grants, compared with 26 in the 2015–2019 window — a +0% 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. NISSEI PLASTIC INDUSTRIAL CO., LTD.'s 10.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NISSEI PLASTIC INDUSTRIAL CO., LTD. against peers pursuing similar technology classes.
