What this shows Corumat's Innovation Score is 42.9/100 (top 29% 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 Corumat?

Each dot is one of Corumat’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). Corumat’s own 31.4 claims/patent is ABOVE the 16.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Corumat's grants concentrate

Corumat, Inc. is a focused PatentsView assignee: 11 CPC subclasses with 100% of grants classified under B29C (Shaping OR Joining OF PLASTICS; Shaping OF Material IN A Plastic State, NOT Otherwise Provided FOR; After-treatment OF THE Shaped Products, e.g. Repairing). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2019. By volume, Corumat sits between Cornell Dubilier Marketing, Inc. and Costruzioni Elettroniche Industriali Automatismi S.p.A. C.E.I.A. S.P.A..

Corumat's three-year grant acceleration

Corumat, Inc. shows 3 grants in 2022–2024 against only 2 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.
