What this shows HDT's Innovation Score is 53.5/100 (top 9% 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 HDT?

Each dot is one of HDT’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). HDT’s own 30.9 claims/patent is ABOVE the 11.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where HDT's grants concentrate

HDT Bio Corp. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2023 (6 grants) versus a trough of 2 in 2024. By volume, HDT sits between Hangzhou Silan Microelectronics Co., Ltd. and Heraeus Quartz North America LLC.

HDT's three-year grant acceleration

HDT Bio Corp. shows 13 grants in 2022–2024 against only 0 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.
