Does more volume mean deeper claims for Waldemar?

Each dot is one of Waldemar’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). Waldemar’s own 16.6 claims/patent is ABOVE the 12.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Waldemar's grants concentrate

Waldemar Link GmbH & Co. KG is a focused PatentsView assignee: 15 CPC subclasses with 74.5% 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 2022 (9 grants) versus a trough of 1 in 2015. By volume, Waldemar sits between University OF Leicester and AIC Innovations Group, Inc..

Waldemar's three-year grant acceleration

Waldemar Link GmbH & Co. KG shows 21 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.
