Does more volume mean deeper claims for Shanghai?

Each dot is one of Shanghai’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). Shanghai’s own 12.3 claims/patent is ABOVE the 1.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Shanghai's grants concentrate

Shanghai Liangxin Electrical Co., Ltd. is a focused PatentsView assignee: 1 CPC subclasses with 100% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2020. By volume, Shanghai sits between Shakira Limited and Shenzhen Crazymonkey Technology Co., Ltd..

Shanghai's three-year grant acceleration

Shanghai Liangxin Electrical Co., Ltd. shows 2 grants in 2022–2024 against only 4 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.
