What this shows Advanced's Innovation Score is 53.6/100 (top 9% 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 Advanced?

Each dot is one of Advanced’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). Advanced’s own 15.1 claims/patent is at or below the 17.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Advanced's grants concentrate

Advanced Micro-fabrication Equipment Inc. China is a focused PatentsView assignee: 12 CPC subclasses with 91.2% of grants classified under H01J (Electric Discharge Tubes OR Discharge Lamps). Peak complete grant year is 2022 (8 grants) versus a trough of 1 in 2018. By volume, Advanced sits between enVerid Systems, Inc. and Amicro Semiconductor Co., Ltd..

Advanced's three-year grant acceleration

Advanced Micro-fabrication Equipment Inc. China shows 23 grants in 2022–2024 against only 7 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.
