Does more volume mean deeper claims for Zensun?

Each dot is one of Zensun’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). Zensun’s own 14.7 claims/patent is ABOVE the 11.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zensun's grants concentrate

Zensun (Shanghai) Science & Technology, Co., Ltd. is a focused PatentsView assignee: 19 CPC subclasses with 90.9% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2017 (6 grants) versus a trough of 2 in 2015. By volume, Zensun sits between Wi-Charge Ltd. and iUNU, Inc..

Zensun's three-year grant acceleration

Zensun (Shanghai) Science & Technology, Co., Ltd. shows 11 grants in 2022–2024 against only 7 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.
