Does more volume mean deeper claims for Sichuan?

Each dot is one of Sichuan’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). Sichuan’s own 26.8 claims/patent is ABOVE the 15.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sichuan's grants concentrate

Sichuan Kelun-biotech Biopharmaceutical Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2021 (8 grants) versus a trough of 1 in 2018. By volume, Sichuan sits between Shenzhen Institute OF Terahertz Technology AND Innovation and Stoneridge, Inc..

Sichuan's three-year grant acceleration

Sichuan Kelun-biotech Biopharmaceutical Co., Ltd. shows 12 grants in 2022–2024 against only 12 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.
