Does more volume mean deeper claims for Tau-pnu?

Each dot is one of Tau-pnu’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). Tau-pnu’s own 8.1 claims/patent is at or below the 14.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tau-pnu's grants concentrate

Tau-pnu Medical Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 47.4% 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 (9 grants) versus a trough of 1 in 2022. By volume, Tau-pnu sits between Takeuchi MFG., Co., Ltd. and THE European Union, Represented BY THE European Commission.

Tau-pnu's three-year grant acceleration

Tau-pnu Medical Co., Ltd. shows 11 grants in 2022–2024 against only 8 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.
