What this shows Sigvaris's Innovation Score is 36.5/100 (top 46% 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 Sigvaris?

Each dot is one of Sigvaris’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). Sigvaris’s own 15.9 claims/patent is ABOVE the 10.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sigvaris's grants concentrate

Sigvaris AG is a focused PatentsView assignee: 12 CPC subclasses with 85.7% 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 (3 grants) versus a trough of 1 in 2018. By volume, Sigvaris sits between Shinsegae International Inc. and Sita Information Networking Computing USA, Inc..

Sigvaris's three-year grant acceleration

Sigvaris AG shows 4 grants in 2022–2024 against only 5 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.
