# Prior Use Product Guide — All 45 Nice Classes

Sorted by top-player net profit margin (highest first). Lowest-cost single branded product per class for a sole proprietor working from a home office. Goal: one real sale per class to establish prior use in commerce.

**Branding method for most goods:** Buy unbranded product, print adhesive label at home (Avery labels + home printer, ~$0.10/unit), affix to product or packaging, sell one unit across state lines (Etsy, eBay, or direct invoice). Photograph everything.

**Bona fide use requirement:** USPTO requires real transactions with real customers who actually wanted the product. Selling one unit is fine. Fabricating fake sales or selling to yourself is fraud on the USPTO. Keep specimens: photos of the branded product as sold, receipts, shipping records.
