Does more volume mean deeper claims for Calderys?

Each dot is one of Calderys’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). Calderys’s own 20.0 claims/patent is ABOVE the 13.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Calderys's grants concentrate

Calderys France is a focused PatentsView assignee: 3 CPC subclasses with 100% 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). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2016. By volume, Calderys sits between C7th Limited and Camozzi Automation S.P.A..

Calderys's three-year grant acceleration

Calderys France shows 1 grants in 2022–2024 against only 0 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.
