Does more volume mean deeper claims for Touchstone?
Each dot is one of Touchstone’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). Touchstone’s own 15.8 claims/patent is ABOVE the 15.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Touchstone's grants concentrate
Touchstone International Medical Science Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2022 (7 grants) versus a trough of 1 in 2017. By volume, Touchstone sits between The Nisshin OilliO Group, Ltd. and Universiteit Twente.
Touchstone's three-year grant acceleration
Touchstone International Medical Science Co., Ltd. shows 13 grants in 2022–2024 against only 9 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.
