Where Bolton's grants concentrate

Bolton Medical, Inc. is a focused PatentsView assignee: 9 CPC subclasses with 81.8% 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 2023 (20 grants) versus a trough of 4 in 2020. By volume, Bolton sits between Technische Universitaet Dresden and Corteva Agriscience LLC.

Bolton's three-year grant acceleration

Bolton Medical, Inc. shows 49 grants in 2022–2024 against only 17 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.
