What this shows Corentec's Innovation Score is 26.2/100 (20th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Corentec?

Each dot is one of Corentec’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). Corentec’s own 12.5 claims/patent is at or below the 17.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Corentec's grants concentrate

Corentec Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 81.5% 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 2021 (10 grants) versus a trough of 1 in 2015. By volume, Corentec sits between Clariant Corporation and Denso Electronics Corporation.

Corentec's three-year grant acceleration

Corentec Co., Ltd. shows 6 grants in 2022–2024 against only 18 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.
