Portfolio overview

KOYO Machine Industries Co., Ltd. has been granted 11 US utility patents between 2016 and 2023, placing KOYO Machine Industries Co., Ltd. at rank #24,642 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.8 claims per patent with primary concentration in F16D (COUPLINGS FOR TRANSMITTING ROTATION; CLUTCHES; BRAKES). As a Foreign Corporation, KOYO Machine Industries Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, KOYO sits between Korea Fuel-tech Corporation (11 patents, rank #24,638) and KWAI Inc. (11 patents, rank #24,646) - the closest US assignees by grant volume. The composite Innovation Score of 27.1/100 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 3 grants, compared with 8 in the 2015–2019 window, a -62% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. KOYO Machine Industries Co., Ltd.'s 5.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark KOYO Machine Industries 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.
