What this shows ADX's Innovation Score is 43.8/100 (top 27% 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 ADX?

Each dot is one of ADX’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). ADX’s own 21.8 claims/patent is ABOVE the 12.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where ADX's grants concentrate

ADX Research, Inc. is a focused PatentsView assignee: 9 CPC subclasses with 50% of grants classified under H03F (Amplifiers). By volume, ADX sits between Advanced Manufacture Technology Center, China Academy OF Machinery Science & Technology and Aeolus Tyre Co., Ltd..

ADX's three-year grant acceleration

ADX Research, Inc. shows 2 grants in 2022–2024 against only 1 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.
