Portfolio overview

Sugino Machine Limited has been granted 99 US utility patents between 2015 and 2025, placing Sugino Machine Limited at rank #3,688 across all assignees tracked by PlainPatent. This portfolio spans 47 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.5 claims per patent with primary concentration in B08B (CLEANING IN GENERAL; PREVENTION OF FOULING IN GENERAL). As a Foreign Corporation, Sugino Machine Limited is one of the more focused assignees in the PatentsView dataset. By volume, Sugino sits between National University Corporation KOBE University (99 patents, rank #3,684) and TCI Co., Ltd. (99 patents, rank #3,692) - the closest US assignees by grant volume. The composite Innovation Score of 51.2/100 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 59 grants, compared with 40 in the 2015–2019 window, a +48% 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. Sugino Machine Limited's 9.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 47 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sugino Machine Limited 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.
