Portfolio overview

Ebara International Corporation has been granted 9 US utility patents between 2015 and 2018, placing Ebara International Corporation at rank #28,618 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.8 claims per patent with primary concentration in F25J (LIQUEFACTION, SOLIDIFICATION OR SEPARATION OF GASES OR GASEOUS ; OR LIQUEFIED GASEOUS; MIXTURES BY PRESSURE AND COLD TREATMENT ; OR BY BRINGING THEM INTO THE SUPERCRITICAL STATE). As a US Corporation, Ebara International Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Ebara sits between Eagle Outdoor Camping Products Co., Ltd. (9 patents, rank #28,614) and Ecole Centrale DE Nantes (9 patents, rank #28,622) - the closest US assignees by grant volume. The composite Innovation Score of 23.1/100 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 0 grants, compared with 9 in the 2015–2019 window, a -100% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. Ebara International Corporation's 5.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ebara International 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.
