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 11.3 claims/patent is ABOVE the 10.0 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 LHD Institute OF NEW Energy, LLC is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under F03B (Machines OR Engines FOR Liquids). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, Hangzhou sits between Hangzhou Canaan Intelligence Information Technology Co., Ltd and Hangzhou Sicco Art-technology Co., Ltd.

Hangzhou's three-year grant acceleration

Hangzhou LHD Institute OF NEW Energy, LLC shows 3 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.
