Portfolio overview

Rondo Energy, Inc. has been granted 44 US utility patents between 2022 and 2025, placing Rondo Energy, Inc. at rank #7,468 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 31.7 claims per patent with primary concentration in F28D (HEAT-EXCHANGE APPARATUS, NOT PROVIDED FOR IN ANOTHER SUBCLASS, IN WHICH THE HEAT-EXCHANGE MEDIA DO NOT COME INTO DIRECT CONTACT). As a US Corporation, Rondo Energy, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Rondo sits between Pulse Biosciences, Inc. (44 patents, rank #7,464) and Shenzhen Sensetime Technology Co., Ltd. (44 patents, rank #7,472) - the closest US assignees by grant volume. The composite Innovation Score of 62.3/100 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. Historical data spans 2022 through 2025, with 44 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Rondo Energy, Inc.'s 31.7 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 16 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Rondo Energy, Inc. 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.
