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.
