What this shows Dais's Innovation Score is 37.0/100 (top 45% 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 Dais?

Each dot is one of Dais’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). Dais’s own 16.5 claims/patent is ABOVE the 9.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dais's grants concentrate

Dais Analytic Corporation is a focused PatentsView assignee: 15 CPC subclasses with 50% of grants classified under F28D (Heat-exchange Apparatus, NOT Provided FOR IN Another Subclass, IN Which THE Heat-exchange Media DO NOT Come Into Direct Contact). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2015. By volume, Dais sits between Daewon Precision Industrial Co., Ltd and Darco International, Inc..

Dais's three-year grant acceleration

Dais Analytic Corporation shows 1 grants in 2022–2024 against only 1 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.
