What this shows Amprius's Innovation Score is 34.2/100 (47th 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 Amprius?

Each dot is one of Amprius’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). Amprius’s own 20.2 claims/patent is ABOVE the 11.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Amprius's grants concentrate

Amprius, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2018 (6 grants) versus a trough of 1 in 2022. By volume, Amprius sits between Airlite Plastics Co. and Archem Inc..

Amprius's three-year grant acceleration

Amprius, Inc. shows 1 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.
