What this shows Alto's Innovation Score is 31.0/100 (36th percentile 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 Alto?

Each dot is one of Alto’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). Alto’s own 11.4 claims/patent is at or below the 16.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Alto's grants concentrate

Alto Memory Technology Corporation is a focused PatentsView assignee: 4 CPC subclasses with 78.6% of grants classified under G11C (Static Stores). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2018. By volume, Alto sits between Allprofessional MFG. Co., Ltd. and Amphenol Assembletech (XIAMEN) Co., Ltd.

Alto's three-year grant acceleration

Alto Memory Technology Corporation shows 7 grants in 2022–2024 against only 6 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.
