What this shows Silcart's Innovation Score is 29.6/100 (31st 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 Silcart?

Each dot is one of Silcart’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). Silcart’s own 6.4 claims/patent is at or below the 15.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Silcart's grants concentrate

Silcart SPA is a focused PatentsView assignee: 13 CPC subclasses with 55.6% of grants classified under B32B (Layered Products, i.e. Products Built-up OF Strata OF Flat OR Non-flat, e.g. Cellular OR Honeycomb, Form). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2018. By volume, Silcart sits between Sichuan Haisco Pharmaceutical Co., Ltd. and Simotec Co., Ltd..

Silcart's three-year grant acceleration

Silcart SPA shows 3 grants in 2022–2024 against only 4 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.
