Portfolio overview
SHIMA SEIKI MFG., LTD. has been granted 28 US utility patents between 2015 and 2024, placing SHIMA SEIKI MFG., LTD. at rank #11,065 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.3 claims per patent with primary concentration in D04B (KNITTING). As a Foreign Corporation, SHIMA SEIKI MFG., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 34.3/100 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 9 grants, compared with 19 in the 2015–2019 window — a -53% 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. SHIMA SEIKI MFG., LTD.'s 7.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SHIMA SEIKI MFG., LTD. against peers pursuing similar technology classes.
