What this shows Pfeiffer's Innovation Score is 53.5/100 (top 9% 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 Pfeiffer?

Each dot is one of Pfeiffer’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). Pfeiffer’s own 14.6 claims/patent is at or below the 15.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Pfeiffer's grants concentrate

Pfeiffer Vacuum is a focused PatentsView assignee: 33 CPC subclasses with 36.2% of grants classified under F04D (Non-positive-displacement Pumps). Peak complete grant year is 2022 (10 grants) versus a trough of 2 in 2016. By volume, Pfeiffer sits between Nextiva, Inc. and Phoenix Industries Pty Ltd.

Pfeiffer's three-year grant acceleration

Pfeiffer Vacuum shows 20 grants in 2022–2024 against only 12 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.
