Does more volume mean deeper claims for Campvalley?

Each dot is one of Campvalley’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). Campvalley’s own 13.7 claims/patent is at or below the 15.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Campvalley's grants concentrate

Campvalley (Xiamen) Co., Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 69% of grants classified under E04H (Buildings OR Like Structures FOR Particular PURPOSES; Swimming OR Splash Baths OR POOLS; MASTS; FENCING; Tents OR Canopies, IN General). Peak complete grant year is 2019 (11 grants) versus a trough of 1 in 2023. By volume, Campvalley sits between Chongqing Jinkang NEW Energy Vehicle Co., Ltd. and Danfoss Micro Channel Heat Exchanger (JIAXING) Co., Ltd..

Campvalley's three-year grant acceleration

Campvalley (Xiamen) Co., Ltd. shows 8 grants in 2022–2024 against only 13 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.
