What this shows DHK's Innovation Score is 42.5/100 (top 31% 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 DHK?

Each dot is one of DHK’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). DHK’s own 12.6 claims/patent is ABOVE the 11.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where DHK's grants concentrate

DHK Storage, Inc. is a focused PatentsView assignee: 7 CPC subclasses with 70.6% of grants classified under H10N (Electric Solid-state Devices NOT Otherwise Provided FOR). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2015. By volume, DHK sits between DD Karma LLC and Dong-a Pencil Co., Ltd..

DHK's three-year grant acceleration

DHK Storage, Inc. shows 7 grants in 2022–2024 against only 3 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.
