Where KJ's grants concentrate

KJ Chemicals Corporation is a focused PatentsView assignee: 17 CPC subclasses with 77.8% 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 2020 (3 grants) versus a trough of 1 in 2017. By volume, KJ sits between Kezar Life Sciences, Inc. and Kobo Products. Inc..

KJ's three-year grant acceleration

KJ Chemicals Corporation shows 4 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.
