What this shows D.o.r.c.'s Innovation Score is 29.3/100 (30th 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 D.o.r.c.?

Each dot is one of D.o.r.c.’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). D.o.r.c.’s own 9.6 claims/patent is at or below the 16.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where D.o.r.c.'s grants concentrate

D.O.R.C. Dutch Ophthalmic Research Center (International) B.V. is a focused PatentsView assignee: 6 CPC subclasses with 92.3% 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 2019 (4 grants) versus a trough of 1 in 2020. By volume, D.o.r.c. sits between Curbell Medical Products, Inc. and Dashamerica, Inc..

D.o.r.c.'s three-year grant acceleration

D.O.R.C. Dutch Ophthalmic Research Center (International) B.V. shows 6 grants in 2022–2024 against only 7 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.
