Does more volume mean deeper claims for Sunnylove?

Each dot is one of Sunnylove’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). Sunnylove’s own 13.4 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sunnylove's grants concentrate

Sunnylove Baby Products Zhuhai Co., Ltd is a focused PatentsView assignee: 7 CPC subclasses with 37.5% of grants classified under B62B (Hand-propelled Vehicles, e.g. Hand Carts OR PERAMBULATORS; Sledges). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2017. By volume, Sunnylove sits between SUN Pharmaceutical Industries (AUSTRALIA) PTY Ltd and Suppremol GMBH.

Sunnylove's three-year grant acceleration

Sunnylove Baby Products Zhuhai Co., Ltd shows 1 grants in 2022–2024 against only 4 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.
