Portfolio overview

Kikusui Seisakusho Ltd. has been granted 24 US utility patents between 2015 and 2025, placing Kikusui Seisakusho Ltd. at rank #12,503 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.1 claims per patent with primary concentration in B30B (PRESSES IN GENERAL). As a Foreign Corporation, Kikusui Seisakusho Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Kikusui sits between Jasco Corporation (24 patents, rank #12,499) and Korea Institute OF Science & Technology Information (24 patents, rank #12,507) - the closest US assignees by grant volume. The composite Innovation Score of 40.3/100 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 19 grants, compared with 5 in the 2015–2019 window, a +280% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Kikusui Seisakusho Ltd.'s 18.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kikusui Seisakusho 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.
