What this shows Plus's Innovation Score is 37.6/100 (top 43% 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 Plus?

Each dot is one of Plus’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). Plus’s own 3.2 claims/patent is at or below the 17.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Plus's grants concentrate

Plus Meditech Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 20% 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 2018 (5 grants) versus a trough of 1 in 2015. By volume, Plus sits between Plessey Semiconductors Ltd and Powerphase International, LLC.

Plus's three-year grant acceleration

Plus Meditech Co., Ltd. shows 4 grants in 2022–2024 against only 0 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.
