Overall rank by patents
#705
Across all tracked assignees
USPTO PatentsView assignee record - 645 granted patents across 139 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F01D (NON-POSITIVE DISPLACEMENT MACHINES OR ENGINES, e.g. STEAM TURBINES).
The verdict
Siemens holds 645 US patents across 139 technology areas, rank #705 of 50,000 tracked assignees.
Siemens Energy, Inc. has been granted 645 US utility patents between 2015 and 2025, placing Siemens Energy, Inc. at rank #705 across all assignees tracked by PlainPatent. This portfolio spans 139 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.3 claims per patent with primary concentration in F01D (NON-POSITIVE DISPLACEMENT MACHINES OR ENGINES, e.g. STEAM TURBINES). As a US Corporation, Siemens Energy, Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Siemens sits between CITY University OF HONG KONG (646 patents, rank #701) and S. C. Johnson & SON, Inc. (640 patents, rank #709) - the closest US assignees by grant volume. The composite Innovation Score of 59.9/100 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 102 grants, compared with 543 in the 2015–2019 window, a -81% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Siemens Energy, Inc.'s 15.3 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 Siemens Energy, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Siemens's 645 grants land it in the top 4% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
