What this shows Chdi's Innovation Score is 43.4/100 (top 28% 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 Chdi?

Each dot is one of Chdi’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). Chdi’s own 20.0 claims/patent is ABOVE the 12.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chdi's grants concentrate

Chdi Foundation, Inc. is a focused PatentsView assignee: 11 CPC subclasses with 92% of grants classified under C07D (Heterocyclic Compounds). Peak complete grant year is 2018 (10 grants) versus a trough of 1 in 2020. By volume, Chdi sits between BeiGene, Ltd. and CSIR.

Chdi's three-year grant acceleration

Chdi Foundation, Inc. shows 12 grants in 2022–2024 against only 13 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.
