Does more volume mean deeper claims for Tianjin?
Each dot is one of Tianjin’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). Tianjin’s own 27.8 claims/patent is ABOVE the 12.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Tianjin's grants concentrate
Tianjin Hemay Pharmaceutical Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2020. By volume, Tianjin sits between Thrane & Thrane A/S and TIV, Inc..
Tianjin's three-year grant acceleration
Tianjin Hemay Pharmaceutical Co., Ltd. shows 4 grants in 2022–2024 against only 1 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.
