Portfolio overview

Nippon Suisan Kaisha, Ltd has been granted 62 US utility patents between 2015 and 2025, placing Nippon Suisan Kaisha, Ltd at rank #5,531 across all assignees tracked by PlainPatent. This portfolio spans 30 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.0 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a Foreign Corporation, Nippon Suisan Kaisha, Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Nippon sits between Medivators Inc. (62 patents, rank #5,527) and Pacific Industrial Co., Ltd. (62 patents, rank #5,535) - the closest US assignees by grant volume. 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 37 grants, compared with 25 in the 2015–2019 window, a +48% 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 Suisan Kaisha, Ltd's 13.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 30 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nippon Suisan Kaisha, 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.
