What this shows Dualitas'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 Dualitas?

Each dot is one of Dualitas’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). Dualitas’s own 18.6 claims/patent is ABOVE the 13.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dualitas's grants concentrate

Dualitas Ltd is a focused PatentsView assignee: 15 CPC subclasses with 95.3% of grants classified under G03H (Holographic Processes OR Apparatus). Peak complete grant year is 2022 (16 grants) versus a trough of 2 in 2019. By volume, Dualitas sits between Coriant Oy and Focal Point, LLC.

Dualitas's three-year grant acceleration

Dualitas Ltd shows 34 grants in 2022–2024 against only 8 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.
