Does more volume mean deeper claims for Keystone?

Each dot is one of Keystone’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). Keystone’s own 18.0 claims/patent is ABOVE the 9.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Keystone's grants concentrate

Keystone Technologies, LLC is a focused PatentsView assignee: 5 CPC subclasses with 62.5% of grants classified under G09F (DISPLAYING; ADVERTISING; SIGNS; Labels OR NAME-PLATES; Seals). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2022. By volume, Keystone sits between Kerley & Co. Ltd. and KinnexA, Inc..

Keystone's three-year grant acceleration

Keystone Technologies, LLC 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.
