Does more volume mean deeper claims for Roman?

Each dot is one of Roman’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). Roman’s own 20.2 claims/patent is ABOVE the 15.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Roman's grants concentrate

Roman Cement, LLC is a focused PatentsView assignee: 7 CPC subclasses with 95% of grants classified under C04B (Lime, MAGNESIA; SLAG; CEMENTS; Compositions Thereof, e.g. Mortars, Concrete OR Like Building MATERIALS; Artificial Stone ; Ceramics ; REFRACTORIES; Treatment OF Natural Stone).

Roman's three-year grant acceleration

Roman Cement, LLC shows 5 grants in 2022–2024 against only 7 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.
