Portfolio overview

Westinghouse Electric Company Llc has been granted 367 US utility patents between 2015 and 2025, placing Westinghouse Electric Company Llc at rank #1,161 across all assignees tracked by PlainPatent. This portfolio spans 119 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.8 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a US Corporation, Westinghouse Electric Company Llc is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Westinghouse sits between Enplas Corporation (367 patents, rank #1,157) and GOJO Industries, Inc. (365 patents, rank #1,165) - the closest US assignees by grant volume. The composite Innovation Score of 60.3/100 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 191 grants, compared with 176 in the 2015–2019 window, a +9% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Westinghouse Electric Company Llc's 13.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Westinghouse Electric Company Llc 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.
