What this shows Ultramemory's Innovation Score is 27.3/100 (23rd 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 Ultramemory?

Each dot is one of Ultramemory’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). Ultramemory’s own 8.1 claims/patent is at or below the 13.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ultramemory's grants concentrate

Ultramemory Inc. is a focused PatentsView assignee: 8 CPC subclasses with 82.4% of grants classified under G11C (Static Stores). Peak complete grant year is 2020 (6 grants) versus a trough of 2 in 2019. By volume, Ultramemory sits between Ubtech North America Research AND Development Center Corp and Universal Global Scientific Industrial Co., Ltd..

Ultramemory's three-year grant acceleration

Ultramemory Inc. shows 4 grants in 2022–2024 against only 11 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.
