Does more volume mean deeper claims for 4C?

Each dot is one of 4C’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). 4C’s own 18.3 claims/patent is ABOVE the 16.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where 4C's grants concentrate

4C Medical Technologies, Inc. is a focused PatentsView assignee: 2 CPC subclasses with 95.5% 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 2024 (10 grants) versus a trough of 1 in 2019. By volume, 4C sits between mirOculus Inc. and ACell, Inc..

4C's three-year grant acceleration

4C Medical Technologies, Inc. shows 12 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.
