Does more volume mean deeper claims for Kimpai?

Each dot is one of Kimpai’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). Kimpai’s own 12.0 claims/patent is ABOVE the 10.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kimpai's grants concentrate

Kimpai Lamitube Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under B32B (Layered Products, i.e. Products Built-up OF Strata OF Flat OR Non-flat, e.g. Cellular OR Honeycomb, Form). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2020. By volume, Kimpai sits between Kieran Murphy LLC and Kingtiger Technology (CANADA) Inc..

Kimpai's three-year grant acceleration

Kimpai Lamitube Co., Ltd. shows 2 grants in 2022–2024 against only 3 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.
