What this shows Unirac's Innovation Score is 57.9/100 (top 5% 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 Unirac?

Each dot is one of Unirac’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). Unirac’s own 12.7 claims/patent is ABOVE the 12.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Unirac's grants concentrate

Unirac, Inc. is a focused PatentsView assignee: 20 CPC subclasses with 56.9% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2024 (21 grants) versus a trough of 2 in 2015. By volume, Unirac sits between Polar Electro Oy and Aledia.

Unirac's three-year grant acceleration

Unirac, Inc. shows 46 grants in 2022–2024 against only 17 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.
