Does more volume mean deeper claims for Chagrinovations?

Each dot is one of Chagrinovations’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). Chagrinovations’s own 7.3 claims/patent is at or below the 10.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chagrinovations's grants concentrate

Chagrinovations, LLC is a focused PatentsView assignee: 4 CPC subclasses with 20% of grants classified under B01F (Mixing, e.g. Dissolving, Emulsifying OR Dispersing). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2021. By volume, Chagrinovations sits between Cerebral Assessment Systems, LLC and Checkerspot, Inc..

Chagrinovations's three-year grant acceleration

Chagrinovations, LLC shows 7 grants in 2022–2024 against only 1 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.
