Where HK's grants concentrate

HK Marketing LC is a focused PatentsView assignee: 3 CPC subclasses with 22.2% of grants classified under E04C (Structural ELEMENTS; Building Materials). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2016. By volume, HK sits between Histologics LLC and Horticulture Innovation Australia Limited.

HK's three-year grant acceleration

HK Marketing LC shows 1 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.
