What this shows The's Innovation Score is 46.0/100 (top 22% 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 The?

Each dot is one of The’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). The’s own 13.9 claims/patent is ABOVE the 13.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where The's grants concentrate

The Eastern Company is a focused PatentsView assignee: 27 CPC subclasses with 43.9% of grants classified under E05B (LOCKS; Accessories THEREFOR; Handcuffs). Peak complete grant year is 2021 (10 grants) versus a trough of 2 in 2019. By volume, The sits between Tatsuno Corporation and United States Endoscopy Group, Inc..

The's three-year grant acceleration

The Eastern Company shows 14 grants in 2022–2024 against only 18 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.
