What this shows Dri-steem's Innovation Score is 38.8/100 (top 40% 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 Dri-steem?

Each dot is one of Dri-steem’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). Dri-steem’s own 11.3 claims/patent is at or below the 16.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dri-steem's grants concentrate

Dri-steem Corporation is a focused PatentsView assignee: 20 CPC subclasses with 100% of grants classified under F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR Currents FOR Screening). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2018. By volume, Dri-steem sits between DNA Script and Dsi-iti, Inc..

Dri-steem's three-year grant acceleration

Dri-steem Corporation shows 3 grants in 2022–2024 against only 3 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.
