Portfolio overview

REN FUEL K2B AB has been granted 6 US utility patents between 2018 and 2022, placing REN FUEL K2B AB at rank #42,558 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.7 claims per patent with primary concentration in C07G (COMPOUNDS OF UNKNOWN CONSTITUTION). As a Foreign Corporation, REN FUEL K2B AB is one of the more focused assignees in the PatentsView dataset. By volume, REN sits between Regina Catene Calibrate S.p.a. (6 patents, rank #42,554) and Repnow Inc. (6 patents, rank #42,562) - the closest US assignees by grant volume. The composite Innovation Score of 31.9/100 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 3 grants, compared with 3 in the 2015–2019 window, a +0% 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. REN FUEL K2B AB's 18.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark REN FUEL K2B AB 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.
