What this shows Unilumin's Innovation Score is 47.7/100 (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 Unilumin?

Each dot is one of Unilumin’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). Unilumin’s own 7.2 claims/patent is at or below the 16.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Unilumin's grants concentrate

Unilumin Group Co., Ltd is a focused PatentsView assignee: 21 CPC subclasses with 44.2% of grants classified under G09F (DISPLAYING; ADVERTISING; SIGNS; Labels OR NAME-PLATES; Seals). Peak complete grant year is 2018 (10 grants) versus a trough of 1 in 2015. By volume, Unilumin sits between Tsudakoma Kogyo Kabushiki Kaisha and Vaccinex, Inc..

Unilumin's three-year grant acceleration

Unilumin Group Co., Ltd shows 17 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.
