What this shows Xi'an's Innovation Score is 50.5/100 (top 13% 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 Xi'an?

Each dot is one of Xi'an’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). Xi'an’s own 12.1 claims/patent is at or below the 15.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Xi'an's grants concentrate

Xi'an Novastar Tech Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 80% of grants classified under G09G (Arrangements OR Circuits FOR Control OF Indicating Devices Using Static Means TO Present Variable Information). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2018. By volume, Xi'an sits between Werlatone, Inc. and Xylem Water Solutions Zelienople LLC.

Xi'an's three-year grant acceleration

Xi'an Novastar Tech Co., Ltd. shows 12 grants in 2022–2024 against only 4 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.
