Amazon removes listings when a rights owner files a patent complaint (and runs the APEX patent evaluation program for utility patents). Sellers who sourced a product from a factory catalogue are often surprised. A one-hour check before you order inventory is cheap insurance. This is a research checklist, not legal advice.
1. Look for patent markings on the existing product
Check the product, its packaging, manuals and the brand's website for "Pat.", "Patent No.", "Patent pending" or a "virtual marking" page (often /patents). Write down every number. A US utility number looks like US 11,234,567 B2; a design patent looks like US D987,654 S.
2. Look up each number
Paste the number into Google Patents. Note the status (active, expired, abandoned), the anticipated expiration, and the claims. See how to check if a patent has expired and how to read patent claims.
3. Search by function, not by listing title
Amazon titles ("Upgraded 2026 Collapsible Bottle") won't match patent language. Describe what the product does: "container with telescoping sidewall that collapses axially". Search Google Patents with 3-5 phrasings, filter to recent years, and check the CPC codes of good hits. Our free patent landscapes by product list real publications for 400+ common products to get you started, e.g. kitchen, pets, electronics.
4. Don't forget design patents
Many Amazon complaints are about design patents, which protect the ornamental look. A product can avoid every utility claim and still look substantially the same as a patented design. Search images on Google Patents and read design vs utility patent searches.
5. Check pending applications
Published applications (numbers like US 2025/0123456 A1) can mature into patents. A "patent pending" product today may be enforceable next year. See what "patent pending" means.
6. Decide what to do with what you found
- Nothing close: lower risk, but a search can't prove absence.
- Close but expired: generally the design is free to use, but check related patents in the same family.
- Close and active: change the design or talk to a patent attorney about a freedom-to-operate (FTO) opinion before buying stock.
