What this shows Vieworks's Innovation Score is 41.0/100 (top 34% 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 Vieworks?

Each dot is one of Vieworks’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). Vieworks’s own 13.3 claims/patent is at or below the 19.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Vieworks's grants concentrate

Vieworks Co., Ltd. is a focused PatentsView assignee: 20 CPC subclasses with 30.6% of grants classified under G01T (Measurement OF Nuclear OR X-radiation). Peak complete grant year is 2020 (6 grants) versus a trough of 1 in 2015. By volume, Vieworks sits between Vernet and Winklevoss IP, LLC.

Vieworks's three-year grant acceleration

Vieworks Co., Ltd. shows 10 grants in 2022–2024 against only 14 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.
