What this shows Unique's Innovation Score is 30.4/100 (34th percentile 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 Unique?

Each dot is one of Unique’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). Unique’s own 11.2 claims/patent is at or below the 14.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Unique's grants concentrate

Unique Materials Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 90.9% of grants classified under C09K (Materials FOR Miscellaneous Applications, NOT Provided FOR Elsewhere). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2021. By volume, Unique sits between UST Global (Singapore) Pte. Limited and Universidade Federal Do Parana.

Unique's three-year grant acceleration

Unique Materials Co., Ltd. shows 2 grants in 2022–2024 against only 7 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.
