Portfolio overview

Asahi Seiko Co., Ltd. has been granted 43 US utility patents between 2015 and 2025, placing Asahi Seiko Co., Ltd. at rank #7,517 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.3 claims per patent with primary concentration in G07D (HANDLING OF COINS OR VALUABLE PAPERS, e.g. TESTING, SORTING BY DENOMINATIONS, COUNTING, DISPENSING, CHANGING OR DEPOSITING). As a Foreign Corporation, Asahi Seiko Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Asahi sits between Aiphone Co., Ltd. (43 patents, rank #7,513) and Anumana, Inc. (43 patents, rank #7,521) - the closest US assignees by grant volume. The composite Innovation Score of 44.3/100 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 22 grants, compared with 21 in the 2015–2019 window, a +5% 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. Asahi Seiko Co., Ltd.'s 10.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Asahi 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.
