What this shows HK's Innovation Score is 36.9/100 (top 45% 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 14.4 claims/patent is ABOVE the 14.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where HK's grants concentrate

HK Army Inc. is a focused PatentsView assignee: 9 CPC subclasses with 64.3% of grants classified under F41B (Weapons FOR Projecting Missiles Without USE OF Explosive OR Combustible Propellant CHARGE; Weapons NOT Otherwise Provided FOR). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2017. By volume, HK sits between Hanwha Land Systems Co., Ltd. and Huaneng Clean Energy Research Institute.

HK's three-year grant acceleration

HK Army Inc. shows 5 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.
