What this shows Aehr's Innovation Score is 37.5/100 (top 44% 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 Aehr?
Each dot is one of Aehr’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). Aehr’s own 19.2 claims/patent is ABOVE the 14.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Aehr's grants concentrate
Aehr Test Systems is a focused PatentsView assignee: 4 CPC subclasses with 95.6% of grants classified under G01R (Measuring Electric VARIABLES; Measuring Magnetic Variables). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2017. By volume, Aehr sits between Zeltiq Aesthetics, Inc. and APR Beauty Group Inc..
Aehr's three-year grant acceleration
Aehr Test Systems shows 11 grants in 2022–2024 against only 13 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.
