What this shows Longsand's Innovation Score is 36.4/100 (top 46% 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 Longsand?

Each dot is one of Longsand’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). Longsand’s own 17.4 claims/patent is ABOVE the 15.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Longsand's grants concentrate

Longsand Limited is a focused PatentsView assignee: 12 CPC subclasses with 60% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2015 (9 grants) versus a trough of 1 in 2018. By volume, Longsand sits between KSB SE & Co. KGaA and Maersk Drilling A/S.

Longsand's three-year grant acceleration

Longsand Limited shows 3 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.
