Does more volume mean deeper claims for Stillwater?

Each dot is one of Stillwater’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). Stillwater’s own 7.6 claims/patent is at or below the 17.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Stillwater's grants concentrate

Stillwater Designs and Audio, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 44.4% of grants classified under H04R (Loudspeakers, Microphones, Gramophone Pick-ups OR Like Acoustic Electromechanical TRANSDUCERS; Deaf-aid SETS; Public Address Systems). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2019. By volume, Stillwater sits between Standex International Corporation and Sungard Availability Services, LP.

Stillwater's three-year grant acceleration

Stillwater Designs and Audio, Inc. shows 6 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.
