Each dot is one of Flex-chem’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). Flex-chem’s own 20.1 claims/patent is ABOVE the 15.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Flex-chem's grants concentrate

Flex-Chem Holding Company, LLC is a focused PatentsView assignee: 3 CPC subclasses with 93.3% of grants classified under C09K (Materials FOR Miscellaneous Applications, NOT Provided FOR Elsewhere). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2015. By volume, Flex-chem sits between FemtoDx, Inc. and Fornia Biosolutions, Inc..

Flex-chem's three-year grant acceleration

Flex-Chem Holding Company, LLC shows 8 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.
