Does more volume mean deeper claims for Jast?

Each dot is one of Jast’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). Jast’s own 11.4 claims/patent is ABOVE the 8.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Jast's grants concentrate

Jast Company Limited is a focused PatentsView assignee: 3 CPC subclasses with 60% of grants classified under G09F (DISPLAYING; ADVERTISING; SIGNS; Labels OR NAME-PLATES; Seals). Peak complete grant year is 2024 (3 grants) versus a trough of 2 in 2023. By volume, Jast sits between Japan Marine United Corporation and JCT Solutions Pty Ltd..

Jast's three-year grant acceleration

Jast Company Limited shows 5 grants in 2022–2024 against only 0 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.
