Where CTC's grants concentrate

CTC BIO, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2021. By volume, CTC sits between CSAA Insurance Services, Inc. and CXL Ophthalmics, Llc.

CTC's three-year grant acceleration

CTC BIO, Inc. shows 1 grants in 2022–2024 against only 3 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.
