Portfolio overview

Sumitomo SHI FW Energia Oy has been granted 17 US utility patents between 2018 and 2025, placing Sumitomo SHI FW Energia Oy at rank #17,241 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.1 claims per patent with primary concentration in F23C (METHODS OR APPARATUS FOR COMBUSTION USING FLUID FUEL OR SOLID FUEL SUSPENDED IN ; A CARRIER GAS OR; AIR). As a Foreign Corporation, Sumitomo SHI FW Energia Oy is one of the more focused assignees in the PatentsView dataset. By volume, Sumitomo sits between Speedinnov (17 patents, rank #17,237) and Swimways Corporation (17 patents, rank #17,245) - the closest US assignees by grant volume. The composite Innovation Score of 42.8/100 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 10 grants, compared with 7 in the 2015–2019 window, a +43% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Sumitomo SHI FW Energia Oy's 19.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sumitomo SHI FW Energia Oy against peers pursuing similar technology classes.
