What this shows CSE's Innovation Score is 48.8/100 (top 16% 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 CSE?

Each dot is one of CSE’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). CSE’s own 18.8 claims/patent is ABOVE the 18.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where CSE's grants concentrate

CSE Co., Ltd. is a focused PatentsView assignee: 22 CPC subclasses with 25% of grants classified under F25D (REFRIGERATORS; Cold ROOMS; ICE-BOXES; Cooling OR Freezing Apparatus NOT Otherwise Provided FOR). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2020. By volume, CSE sits between Crunchfish AB and Cubic Tech Corporation.

CSE's three-year grant acceleration

CSE Co., Ltd. shows 4 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.
