Portfolio overview

FUJI Seiko Co., Ltd. has been granted 36 US utility patents between 2016 and 2023, placing FUJI Seiko Co., Ltd. at rank #8,798 across all assignees tracked by PlainPatent. This portfolio spans 25 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.8 claims per patent with primary concentration in B29D (PRODUCING PARTICULAR ARTICLES FROM PLASTICS OR FROM SUBSTANCES IN A PLASTIC STATE). As a Foreign Corporation, FUJI Seiko Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, FUJI sits between Fastbrick IP PTY Ltd (36 patents, rank #8,794) and Gibson Brands, Inc. (36 patents, rank #8,802) - the closest US assignees by grant volume. The composite Innovation Score of 33.4/100 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 13 grants, compared with 23 in the 2015–2019 window, a -43% 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. FUJI Seiko Co., Ltd.'s 4.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 25 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark FUJI Seiko 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.
