What this shows Sphere's Innovation Score is 39.6/100 (top 38% 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 Sphere?

Each dot is one of Sphere’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). Sphere’s own 17.3 claims/patent is ABOVE the 16.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sphere's grants concentrate

Sphere Fluidics Limited is a focused PatentsView assignee: 15 CPC subclasses with 83.3% of grants classified under B01L (Chemical OR Physical Laboratory Apparatus FOR General USE). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2019. By volume, Sphere sits between Specialty Conveyor B.V. and SR Systems, LLC.

Sphere's three-year grant acceleration

Sphere Fluidics Limited shows 4 grants in 2022–2024 against only 4 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.
