Where Tampro's grants concentrate

Tampro Inc. is a focused PatentsView assignee: 1 CPC subclasses with 16.7% of grants classified under A61F (Filters Implantable Into Blood VESSELS; PROSTHESES; Devices Providing Patency TO, OR Preventing Collapsing OF, Tubular Structures OF THE Body, e.g. STENTS; Orthopaedic, Nursing OR Contraceptive Device). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2021. By volume, Tampro sits between Takazono Corporation and Tangentix Limited.

Tampro's three-year grant acceleration

Tampro Inc. 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.
