What this shows Xi'an's Innovation Score is 43.7/100 (top 27% 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 9.9 claims/patent is at or below the 13.3 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 Institute OF Optics AND Precision Mechanics OF CAS is a focused PatentsView assignee: 9 CPC subclasses with 42.9% of grants classified under G01J (Measurement OF Intensity, Velocity, Spectral Content, Polarisation, Phase OR Pulse Characteristics OF Infrared, Visible OR Ultraviolet LIGHT; COLORIMETRY; Radiation Pyrometry). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2018. By volume, Xi'an sits between X-Bow Launch Systems Inc. and Xlnx, Inc..

Xi'an's three-year grant acceleration

Xi'an Institute OF Optics AND Precision Mechanics OF CAS shows 3 grants in 2022–2024 against only 1 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.
