What this shows TDA's Innovation Score is 51.2/100 (top 12% 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 TDA?

Each dot is one of TDA’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). TDA’s own 13.9 claims/patent is ABOVE the 7.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where TDA's grants concentrate

TDA Research, Inc. is a focused PatentsView assignee: 46 CPC subclasses with 32.5% of grants classified under B01D (Separation). Peak complete grant year is 2016 (7 grants) versus a trough of 1 in 2022. By volume, TDA sits between Somos, Inc. and Toyo Gosei Co., Ltd..

TDA's three-year grant acceleration

TDA Research, Inc. shows 9 grants in 2022–2024 against only 10 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.
