Where D&b's grants concentrate
D&B Audiotechnik GMBH & Co. KG is a focused PatentsView assignee: 3 CPC subclasses with 50% 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 2022 (2 grants) versus a trough of 1 in 2020. By volume, D&b sits between Cytel Inc. and D.H.M. Innovation.
D&b's three-year grant acceleration
D&B Audiotechnik GMBH & Co. KG shows 5 grants in 2022–2024 against only 1 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.
