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 10.6 claims/patent is at or below the 15.3 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 University OF Posts & Telecommunications is a focused PatentsView assignee: 14 CPC subclasses with 27.3% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2022. By volume, Xi'an sits between Wound Care Technologies, Inc. and Xtreme Marine Corporation.
Xi'an's three-year grant acceleration
Xi'an University OF Posts & Telecommunications shows 10 grants in 2022–2024 against only 0 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.
