Does more volume mean deeper claims for Otos?

Each dot is one of Otos’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). Otos’s own 6.8 claims/patent is at or below the 13.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Otos's grants concentrate

Otos Wing Co., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 65.8% 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 (7 grants) versus a trough of 1 in 2016. By volume, Otos sits between National Chain Company and PaloDEx Group Oy.

Otos's three-year grant acceleration

Otos Wing 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.
