What this shows A.'s Innovation Score is 42.9/100 (top 30% 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 A.?

Each dot is one of A.’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). A.’s own 24.0 claims/patent is ABOVE the 17.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where A.'s grants concentrate

A. Duda & Sons, Inc. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under A01H (NEW Plants OR ; NON-TRANSGENIC; Processes FOR Obtaining THEM; Plant Reproduction BY Tissue Culture Techniques). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2018. By volume, A. sits between 2seventy bio, Inc. and ABI Attachments, Inc..

A.'s three-year grant acceleration

A. Duda & Sons, Inc. shows 7 grants in 2022–2024 against only 4 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.
