What this shows DSP's Innovation Score is 61.5/100 (top 3% 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 DSP?

Each dot is one of DSP’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). DSP’s own 21.1 claims/patent is ABOVE the 6.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where DSP's grants concentrate

DSP Group Ltd. is a focused PatentsView assignee: 40 CPC subclasses with 25.8% of grants classified under H04B (Transmission). Peak complete grant year is 2015 (18 grants) versus a trough of 3 in 2019. By volume, DSP sits between Berlin Packaging, LLC and Immunolight, LLC.

DSP's three-year grant acceleration

DSP Group Ltd. shows 24 grants in 2022–2024 against only 15 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.
