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 16.6 claims/patent is ABOVE the 14.6 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 Xinglu Technologies Co., Ltd is a focused PatentsView assignee: 16 CPC subclasses with 100% of grants classified under C08L (Compositions OF Macromolecular Compounds). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2023. By volume, Hangzhou sits between Haldor Advanced Technologies Ltd and Harbor Innovations, LLC.
Hangzhou's three-year grant acceleration
Hangzhou Xinglu Technologies Co., Ltd shows 8 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.
