What this shows Petroceramics's Innovation Score is 43.9/100 (top 27% 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 Petroceramics?

Each dot is one of Petroceramics’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). Petroceramics’s own 22.4 claims/patent is ABOVE the 10.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Petroceramics's grants concentrate

Petroceramics S.p.A. is a focused PatentsView assignee: 21 CPC subclasses with 62.5% 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 2016 (2 grants) versus a trough of 1 in 2019. By volume, Petroceramics sits between Peikko Group OY and Phasestor LLC.

Petroceramics's three-year grant acceleration

Petroceramics S.p.A. shows 3 grants in 2022–2024 against only 3 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.
