What this shows Vocalzoom's Innovation Score is 31.4/100 (38th 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 Vocalzoom?

Each dot is one of Vocalzoom’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). Vocalzoom’s own 16.4 claims/patent is ABOVE the 15.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Vocalzoom's grants concentrate

Vocalzoom Systems Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 66.7% 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 2017 (6 grants) versus a trough of 1 in 2015. By volume, Vocalzoom sits between Vesuvius U S A Corporation and Vatbox, Ltd..

Vocalzoom's three-year grant acceleration

Vocalzoom Systems Ltd. shows 1 grants in 2022–2024 against only 8 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.
