Does more volume mean deeper claims for Anpac?
Each dot is one of Anpac’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). Anpac’s own 35.1 claims/patent is ABOVE the 13.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Anpac's grants concentrate
AnPac Bio-Medical Science Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 85.7% of grants classified under B01L (Chemical OR Physical Laboratory Apparatus FOR General USE). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2019. By volume, Anpac sits between Ameranth, Inc. and Aon Global Operations SE, Singapore Branch.
Anpac's three-year grant acceleration
AnPac Bio-Medical Science Co., Ltd. shows 3 grants in 2022–2024 against only 5 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.
