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 10.2 claims/patent is ABOVE the 10.0 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 Asymchem Pharmaceuticals Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 55.6% of grants classified under C07D (Heterocyclic Compounds). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2020. By volume, Tianjin sits between Thorium Power, Inc. and Tmaxtibero Co., Ltd..

Tianjin's three-year grant acceleration

Tianjin Asymchem Pharmaceuticals Co., Ltd. shows 1 grants in 2022–2024 against only 2 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.
