Portfolio overview

Iris Ohyama Inc. has been granted 137 US utility patents between 2016 and 2025, placing Iris Ohyama Inc. at rank #2,808 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.8 claims per patent with primary concentration in F04D (NON-POSITIVE-DISPLACEMENT PUMPS). As a Foreign Corporation, Iris Ohyama Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Iris sits between GKN Automotive Limited (137 patents, rank #2,804) and Nuovo Pignone SRL (137 patents, rank #2,812) - the closest US assignees by grant volume. The composite Innovation Score of 35.6/100 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 101 grants, compared with 36 in the 2015–2019 window, a +181% 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. Iris Ohyama Inc.'s 1.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Iris Ohyama Inc. 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.
