Portfolio overview

UBE Industries, Ltd. has been granted 220 US utility patents between 2015 and 2025, placing UBE Industries, Ltd. at rank #1,838 across all assignees tracked by PlainPatent. This portfolio spans 80 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.0 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, UBE Industries, Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, UBE sits between WHG Properties, Llc (221 patents, rank #1,834) and The Regents Of The University Of Colorado (219 patents, rank #1,842) - the closest US assignees by grant volume. The composite Innovation Score of 52.2/100 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 43 grants, compared with 177 in the 2015–2019 window, a -76% 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. UBE Industries, Ltd.'s 12.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 80 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark UBE Industries, 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.
