What this shows Cydex's Innovation Score is 42.2/100 (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 Cydex?

Each dot is one of Cydex’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). Cydex’s own 24.5 claims/patent is ABOVE the 17.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Cydex's grants concentrate

CyDex Pharmaceuticals, Inc. is a focused PatentsView assignee: 13 CPC subclasses with 92.3% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2020 (9 grants) versus a trough of 2 in 2015. By volume, Cydex sits between Cayenne Medical, Inc. and Deep Science, LLC.

Cydex's three-year grant acceleration

CyDex Pharmaceuticals, Inc. shows 5 grants in 2022–2024 against only 17 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.
