What this shows Roof's Innovation Score is 47.2/100 (top 19% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Roof?

Each dot is one of Roof’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Roof’s own 16.5 claims/patent is ABOVE the 9.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Roof's grants concentrate

Roof Asset Management USA, Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 66.7% of grants classified under G01J (Measurement OF Intensity, Velocity, Spectral Content, Polarisation, Phase OR Pulse Characteristics OF Infrared, Visible OR Ultraviolet LIGHT; COLORIMETRY; Radiation Pyrometry). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2020. By volume, Roof sits between Rollease Acmeda, Inc. and Rubicon Products, LLC.

Roof's three-year grant acceleration

Roof Asset Management USA, Ltd. shows 5 grants in 2022–2024 against only 1 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
