Frequently asked questions
The store as a service is class 35: the activity of presenting goods for customers to buy. The goods themselves are not covered, so a brand selling its own products also needs the relevant goods class for product-level protection.
Class 35 covers general business services: management, advertising, bookkeeping and tax preparation. Class 36 covers the financial products themselves: banking, payment processing, lending, insurance and real estate.
Business and marketing research are class 35, but software as a service and technical design work are class 42. An agency that also ships a client-facing platform commonly files both.
