What this shows Rockford's Innovation Score is 33.9/100 (46th 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 Rockford?

Each dot is one of Rockford’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). Rockford’s own 9.7 claims/patent is at or below the 12.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Rockford's grants concentrate

Rockford Corporation is a focused PatentsView assignee: 3 CPC subclasses with 36.4% 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 2024 (4 grants) versus a trough of 1 in 2016. By volume, Rockford sits between Ringers Technologies LLC and RSA Protective Technologies, LLC.

Rockford's three-year grant acceleration

Rockford Corporation shows 4 grants in 2022–2024 against only 2 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.
