Portfolio overview

Mikuni Corporation has been granted 113 US utility patents between 2015 and 2025, placing Mikuni Corporation at rank #3,308 across all assignees tracked by PlainPatent. This portfolio spans 48 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.1 claims per patent with primary concentration in F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; DEVICES FOR VENTING OR AERATING). As a Foreign Corporation, Mikuni Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Mikuni sits between Georgia State University Research Foundation (113 patents, rank #3,304) and Sekisui Medical Co., Ltd. (113 patents, rank #3,312) - the closest US assignees by grant volume. The composite Innovation Score of 53.0/100 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 77 grants, compared with 36 in the 2015–2019 window, a +114% 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. Mikuni Corporation's 9.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 48 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mikuni Corporation 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.
