Does more volume mean deeper claims for Chemtor?

Each dot is one of Chemtor’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). Chemtor’s own 20.6 claims/patent is ABOVE the 10.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chemtor's grants concentrate

Chemtor, LP is a focused PatentsView assignee: 21 CPC subclasses with 66.7% of grants classified under C07C (Acyclic OR Carbocyclic Compounds). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2015. By volume, Chemtor sits between Ceribell, Inc. and Chobani LLC.

Chemtor's three-year grant acceleration

Chemtor, LP shows 3 grants in 2022–2024 against only 2 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.
