What this shows Salunda's Innovation Score is 44.6/100 (top 25% 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 Salunda?

Each dot is one of Salunda’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). Salunda’s own 21.8 claims/patent is ABOVE the 10.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Salunda's grants concentrate

Salunda Limited is a focused PatentsView assignee: 24 CPC subclasses with 40% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2015. By volume, Salunda sits between Roivios Limited and Shanghai Research Center FOR Wireless Communications.

Salunda's three-year grant acceleration

Salunda Limited shows 4 grants in 2022–2024 against only 9 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.
