What this shows Union's Innovation Score is 25.0/100 (16th 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 Union?

Each dot is one of Union’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). Union’s own 9.1 claims/patent is at or below the 15.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Union's grants concentrate

Union Optech Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 92.3% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2021. By volume, Union sits between Userzoom Technologies, Inc. and Urugus S.A..

Union's three-year grant acceleration

Union Optech Co., Ltd. shows 3 grants in 2022–2024 against only 6 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.
