Portfolio overview

Ansaldo Energia Switzerland Ag has been granted 179 US utility patents between 2017 and 2023, placing Ansaldo Energia Switzerland Ag at rank #2,189 across all assignees tracked by PlainPatent. This portfolio spans 56 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.9 claims per patent with primary concentration in F05D (INDEXING SCHEME FOR ASPECTS RELATING TO NON-POSITIVE-DISPLACEMENT MACHINES OR ENGINES, GAS-TURBINES OR JET-PROPULSION PLANTS). As a Foreign Corporation, Ansaldo Energia Switzerland Ag is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Ansaldo sits between Olympus Medical Systems Corporation (180 patents, rank #2,185) and CSMC Technologies FAB2 Co., Ltd. (179 patents, rank #2,193) - the closest US assignees by grant volume. The composite Innovation Score of 51.8/100 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 49 grants, compared with 130 in the 2015–2019 window, a -62% 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. Ansaldo Energia Switzerland Ag's 13.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 56 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ansaldo Energia Switzerland Ag 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.
