Portfolio overview

Mimaki Engineering Co., Ltd. has been granted 348 US utility patents between 2015 and 2025, placing Mimaki Engineering Co., Ltd. at rank #1,222 across all assignees tracked by PlainPatent. This portfolio spans 60 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.3 claims per patent with primary concentration in B41J (TYPEWRITERS; SELECTIVE PRINTING MECHANISMS, i.e. MECHANISMS PRINTING OTHERWISE THAN FROM A FORME; CORRECTION OF TYPOGRAPHICAL ERRORS). As a Foreign Corporation, Mimaki Engineering Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Mimaki sits between Amdocs Development Limited (349 patents, rank #1,218) and Tusimple, Inc. (347 patents, rank #1,226) - the closest US assignees by grant volume. The composite Innovation Score of 55.0/100 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 177 grants, compared with 171 in the 2015–2019 window, a +4% 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. Mimaki Engineering Co., Ltd.'s 10.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 60 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mimaki Engineering 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.
