Does more volume mean deeper claims for Graymont?

Each dot is one of Graymont’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). Graymont’s own 20.6 claims/patent is ABOVE the 12.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Graymont's grants concentrate

Graymont (PA) Inc. is a focused PatentsView assignee: 14 CPC subclasses with 87.5% of grants classified under B01D (Separation). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2019. By volume, Graymont sits between Grace Manufacturing, Inc. and Green Source Holdings LLC.

Graymont's three-year grant acceleration

Graymont (PA) Inc. shows 2 grants in 2022–2024 against only 6 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.
