Each dot is one of Taizhou’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). Taizhou’s own 5.5 claims/patent is at or below the 12.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Taizhou Xiaotanglang Infant and Child Products Co., Ltd. is a focused PatentsView assignee: 1 CPC subclasses with 25% of grants classified under A47K (Sanitary Equipment NOT Otherwise Provided FOR ; Toilet Accessories).

Taizhou's three-year grant acceleration

Taizhou Xiaotanglang Infant and Child Products Co., Ltd. shows 7 grants in 2022–2024 against only 0 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.
