What this shows HK's Innovation Score is 19.1/100 (6th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for HK?

Each dot is one of HK’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). HK’s own 5.6 claims/patent is at or below the 12.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

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.
