What this shows Sparq's Innovation Score is 54.0/100 (top 8% 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 Sparq?

Each dot is one of Sparq’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). Sparq’s own 15.5 claims/patent is ABOVE the 11.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sparq's grants concentrate

Sparq Systems Inc. is a focused PatentsView assignee: 14 CPC subclasses with 81.5% of grants classified under H02M (Apparatus FOR Conversion Between AC AND AC, Between AC AND DC, OR Between DC AND DC, AND FOR USE With Mains OR Similar Power Supply SYSTEMS; Conversion OF DC OR AC Input Power Into Surge Output POWER;). Peak complete grant year is 2017 (7 grants) versus a trough of 1 in 2015. By volume, Sparq sits between Siteimprove A/S and Suominen Corporation.

Sparq's three-year grant acceleration

Sparq Systems Inc. shows 8 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.
