Portfolio overview

Subsea 7 Limited has been granted 65 US utility patents between 2015 and 2025, placing Subsea 7 Limited at rank #5,324 across all assignees tracked by PlainPatent. This portfolio spans 38 distinct Cooperative Patent Classification (CPC) subclasses, averaging 22.4 claims per patent with primary concentration in F16L (PIPES; JOINTS OR FITTINGS FOR PIPES; SUPPORTS FOR PIPES, CABLES OR PROTECTIVE TUBING; MEANS FOR THERMAL INSULATION IN GENERAL). As a Foreign Corporation, Subsea 7 Limited is one of the more focused assignees in the PatentsView dataset. By volume, Subsea sits between Seven Bridges Genomics Inc. (65 patents, rank #5,320) and Theragun, Inc. (65 patents, rank #5,328) - the closest US assignees by grant volume. The composite Innovation Score of 54.5/100 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 27 grants, compared with 38 in the 2015–2019 window, a -29% 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. Subsea 7 Limited's 22.4 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 38 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Subsea 7 Limited 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.
