What this shows Dropsa's Innovation Score is 33.8/100 (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 Dropsa?

Each dot is one of Dropsa’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). Dropsa’s own 16.4 claims/patent is ABOVE the 16.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dropsa's grants concentrate

Dropsa S.p.A. is a focused PatentsView assignee: 13 CPC subclasses with 85.7% of grants classified under F16N (Lubricating). Peak complete grant year is 2020 (3 grants) versus a trough of 2 in 2015. By volume, Dropsa sits between Dongguan YIH TEH Electric Products Co., Ltd. and Dataspark, Pte. Ltd..

Dropsa's three-year grant acceleration

Dropsa S.p.A. shows 2 grants in 2022–2024 against only 7 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.
