Does more volume mean deeper claims for Speedrack?

Each dot is one of Speedrack’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). Speedrack’s own 2.2 claims/patent is at or below the 14.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Speedrack's grants concentrate

Speedrack Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 25% of grants classified under A47B (TABLES; DESKS; Office FURNITURE; CABINETS; DRAWERS; General Details OF Furniture). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2021. By volume, Speedrack sits between Smith Systems Manufacturing Company and Starting Industrial Co., Ltd..

Speedrack's three-year grant acceleration

Speedrack Co., Ltd. shows 6 grants in 2022–2024 against only 1 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.
