What this shows Alfa's Innovation Score is 30.8/100 (36th percentile 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 Alfa?

Each dot is one of Alfa’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). Alfa’s own 18.8 claims/patent is ABOVE the 14.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Alfa's grants concentrate

Alfa Laval Vicarb SAS is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under F28D (Heat-exchange Apparatus, NOT Provided FOR IN Another Subclass, IN Which THE Heat-exchange Media DO NOT Come Into Direct Contact). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2018. By volume, Alfa sits between Alesi Surgical Limited and Allergan Holdings France S.A.S..

Alfa's three-year grant acceleration

Alfa Laval Vicarb SAS shows 2 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.
