Does more volume mean deeper claims for Ennis-flint?

Each dot is one of Ennis-flint’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). Ennis-flint’s own 18.4 claims/patent is ABOVE the 17.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ennis-flint's grants concentrate

Ennis-Flint, Inc. is a focused PatentsView assignee: 21 CPC subclasses with 63.6% of grants classified under C09D (Coating Compositions, e.g. Paints, Varnishes OR LACQUERS; Filling PASTES; Chemical Paint OR INK REMOVERS; INKS; Correcting FLUIDS; WOODSTAINS; Pastes OR Solids FOR Colouring OR PRINTING; USE OF Materi). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2020. By volume, Ennis-flint sits between EnerAllies, Inc. and Erwin Junker Maschinenfabrik GmbH.

Ennis-flint's three-year grant acceleration

Ennis-Flint, Inc. shows 6 grants in 2022–2024 against only 4 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.
