Portfolio overview

SEKI Press Co., Ltd. has been granted 7 US utility patents between 2018 and 2024, placing SEKI Press Co., Ltd. at rank #37,337 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.1 claims per patent with primary concentration in B21J (FORGING; HAMMERING; PRESSING METAL; RIVETING; FORGE FURNACES). As a Foreign Corporation, SEKI Press Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, SEKI sits between Securly, Inc. (7 patents, rank #37,333) and Seleggt Gmbh (7 patents, rank #37,341) - the closest US assignees by grant volume. The composite Innovation Score of 30.4/100 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 4 grants, compared with 3 in the 2015–2019 window, a +33% 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. SEKI Press Co., Ltd.'s 11.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SEKI Press Co., Ltd. against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
