Does more volume mean deeper claims for Chukyo?

Each dot is one of Chukyo’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). Chukyo’s own 7.9 claims/patent is at or below the 9.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chukyo's grants concentrate

Chukyo Medical Co., Inc. is a focused PatentsView assignee: 3 CPC subclasses with 83.3% 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 2016 (4 grants) versus a trough of 1 in 2018. By volume, Chukyo sits between Chiba Institute OF Technology and Clara Foods Co..

Chukyo's three-year grant acceleration

Chukyo Medical Co., Inc. shows 3 grants in 2022–2024 against only 4 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.
