What this shows Alexza's Innovation Score is 47.3/100 (top 19% 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 Alexza?

Each dot is one of Alexza’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). Alexza’s own 15.1 claims/patent is at or below the 18.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Alexza's grants concentrate

Alexza Pharmaceuticals, Inc. is a focused PatentsView assignee: 18 CPC subclasses with 88% of grants classified under A61M (Devices FOR Introducing Media Into, OR Onto, THE Body ; Devices FOR Transducing Body Media OR FOR Taking Media From THE Body ; Devices FOR Producing OR Ending Sleep OR Stupor). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2021. By volume, Alexza sits between Agena Bioscience, Inc. and Apex Microelectronics Co., Ltd..

Alexza's three-year grant acceleration

Alexza Pharmaceuticals, Inc. shows 9 grants in 2022–2024 against only 5 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.
