Does more volume mean deeper claims for Guangdong?
Each dot is one of Guangdong’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). Guangdong’s own 16.6 claims/patent is ABOVE the 6.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Guangdong's grants concentrate
Guangdong Raynovent Biotech Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 92.3% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2021. By volume, Guangdong sits between Greater Shine Limited and Guilin University OF Technology.
Guangdong's three-year grant acceleration
Guangdong Raynovent Biotech Co., Ltd. shows 4 grants in 2022–2024 against only 7 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.
