The verdict
Roof holds 6 US patents across 9 technology areas, rank #42,713 of 50,000 tracked assignees.
Roof Asset Management USA, Ltd. has been granted 6 US utility patents between 2020 and 2024, placing Roof Asset Management USA, Ltd. at rank #42,713 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.5 claims per patent with primary concentration in G01J (MEASUREMENT OF INTENSITY, VELOCITY, SPECTRAL CONTENT, POLARISATION, PHASE OR PULSE CHARACTERISTICS OF INFRARED, VISIBLE OR ULTRAVIOLET LIGHT; COLORIMETRY; RADIATION PYROMETRY). As a US Corporation, Roof Asset Management USA, Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Roof sits between Rollease Acmeda, Inc. (6 patents, rank #42,709) and Rubicon Products, Llc (6 patents, rank #42,717) - the closest US assignees by grant volume. The composite Innovation Score of 47.2/100 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 2020 through 2024, with 6 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. Roof Asset Management USA, Ltd.'s 16.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Roof Asset Management USA, Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Roof's 6 grants land it in the top 19% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
