What this shows Delstar's Innovation Score is 47.8/100 (top 18% 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 Delstar?

Each dot is one of Delstar’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). Delstar’s own 19.6 claims/patent is ABOVE the 16.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Delstar's grants concentrate

DelStar Technologies, Inc. is a focused PatentsView assignee: 27 CPC subclasses with 42.9% of grants classified under B01D (Separation). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2017. By volume, Delstar sits between Dataspark, Pte. Ltd. and Digi-Star, LLC.

Delstar's three-year grant acceleration

DelStar Technologies, Inc. shows 5 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.
