Portfolio overview

Ebara Environmental Plant Co., Ltd. has been granted 6 US utility patents between 2023 and 2025, placing Ebara Environmental Plant Co., Ltd. at rank #39,934 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.5 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Ebara Environmental Plant Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Ebara sits between Easydial Inc. (6 patents, rank #39,930) and ECI Technology, Inc. (6 patents, rank #39,938) - the closest US assignees by grant volume. The composite Innovation Score of 45.2/100 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. Historical data spans 2023 through 2025, with 6 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Ebara Environmental Plant Co., Ltd.'s 6.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ebara Environmental Plant 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.
