What this shows Stealthcase'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 Stealthcase?

Each dot is one of Stealthcase’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). Stealthcase’s own 17.0 claims/patent is ABOVE the 14.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Stealthcase's grants concentrate

StealthCase Oy is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under H01Q (Antennas, i.e. Radio Aerials). By volume, Stealthcase sits between State Grid Beijing Electric Power Company and Steinfurth Mess-Systeme GmbH.

Stealthcase's three-year grant acceleration

StealthCase Oy shows 2 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.
