What this shows San-apro's Innovation Score is 33.9/100 (46th 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 San-apro?

Each dot is one of San-apro’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). San-apro’s own 10.5 claims/patent is at or below the 14.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where San-apro's grants concentrate

San-apro Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under C07C (Acyclic OR Carbocyclic Compounds). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2015. By volume, San-apro sits between Safran Data Systems and Sappi Netherlands Services B.V..

San-apro's three-year grant acceleration

San-apro Ltd. 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.
