Does more volume mean deeper claims for Hangzhou?

Each dot is one of Hangzhou’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). Hangzhou’s own 15.3 claims/patent is ABOVE the 7.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hangzhou's grants concentrate

Hangzhou Qulian Technology Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 80% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2022. By volume, Hangzhou sits between H2vr HoldCo, Inc. and HD Networks, LLC.

Hangzhou's three-year grant acceleration

Hangzhou Qulian Technology Co., Ltd. shows 9 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.
