This application represents a software product and hosted service strategy (Classes 9 + 42) — the standard dual-class approach for SaaS brands, filed in July 2020, during the USPTO's pandemic-era filing surge. The 2-class strategy is typical of brands that sell both a product and operate their own retail or digital channel.
