Portfolio overview
Spirax-Sarco Limited has been granted 18 US utility patents between 2015 and 2025, placing Spirax-Sarco Limited at rank #16,391 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.6 claims per patent with primary concentration in F16T (STEAM TRAPS OR LIKE APPARATUS FOR DRAINING-OFF LIQUIDS FROM ENCLOSURES PREDOMINANTLY CONTAINING GASES OR VAPOURS). As a Foreign Corporation, Spirax-Sarco Limited is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 38.6/100 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 6 grants, compared with 12 in the 2015–2019 window — a -50% 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. Spirax-Sarco Limited's 17.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Spirax-Sarco Limited against peers pursuing similar technology classes.
