Does more volume mean deeper claims for Stroma?

Each dot is one of Stroma’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). Stroma’s own 24.5 claims/patent is ABOVE the 12.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Stroma's grants concentrate

Stroma Medical Corporation is a focused PatentsView assignee: 10 CPC subclasses with 100% 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 2024 (5 grants) versus a trough of 1 in 2021. By volume, Stroma sits between Stokely-Van Camp, Inc. and Sultan Qaboos University.

Stroma's three-year grant acceleration

Stroma Medical Corporation shows 11 grants in 2022–2024 against only 1 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.
