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 13.3 claims/patent is at or below the 16.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hangzhou's grants concentrate

Hangzhou Silicon-Magic Semiconductor Technology Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 85.7% of grants classified under H10D (Inorganic Electric Semiconductor Devices). Peak complete grant year is 2022 (3 grants) versus a trough of 2 in 2023. By volume, Hangzhou sits between Huaneng Clean Energy Research Institute and Havis, Inc..

Hangzhou's three-year grant acceleration

Hangzhou Silicon-Magic Semiconductor Technology 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.
