What this shows Saltworks's Innovation Score is 43.2/100 (top 29% 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 Saltworks?

Each dot is one of Saltworks’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). Saltworks’s own 21.4 claims/patent is ABOVE the 15.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Saltworks's grants concentrate

Saltworks Technologies Inc. is a focused PatentsView assignee: 17 CPC subclasses with 84.6% of grants classified under B01D (Separation). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2018. By volume, Saltworks sits between Rotoliptic Technologies Incorporated and Segmint Inc..

Saltworks's three-year grant acceleration

Saltworks Technologies Inc. shows 1 grants in 2022–2024 against only 1 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.
