What this shows Chaei's Innovation Score is 38.2/100 (top 41% 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 Chaei?

Each dot is one of Chaei’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). Chaei’s own 10.1 claims/patent is ABOVE the 7.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chaei's grants concentrate

Chaei Hsin Enterprise Co., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 50% of grants classified under B29C (Shaping OR Joining OF PLASTICS; Shaping OF Material IN A Plastic State, NOT Otherwise Provided FOR; After-treatment OF THE Shaped Products, e.g. Repairing). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2016. By volume, Chaei sits between Centro De Investigación En Alimentación Y Desarrollo, A.C. (CIAD) and Chattem, Inc..

Chaei's three-year grant acceleration

Chaei Hsin Enterprise Co., Ltd. shows 4 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.
