Portfolio overview

Westinghouse Electric Sweden AB has been granted 25 US utility patents between 2015 and 2024, placing Westinghouse Electric Sweden AB at rank #12,309 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.6 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, Westinghouse Electric Sweden AB is one of the more focused assignees in the PatentsView dataset. By volume, Westinghouse sits between Vungle, Inc. (25 patents, rank #12,305) and Xi'an University Of Architecture And Technology (25 patents, rank #12,313) - the closest US assignees by grant volume. The composite Innovation Score of 36.7/100 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 11 grants, compared with 14 in the 2015–2019 window, a -21% 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. Westinghouse Electric Sweden AB's 14.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Westinghouse Electric Sweden AB 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.
