#10 — Патентная чистота и маркетплейсы: как не потерять продажи | Патентование для бизнеса 2026

Lesson 10 of the "Patenting for Business 2026" course. We explore patent purity and why it's important for marketplace sellers to verify products before purchasing large quantities and launching sales. We explain why the argument "I'm not a manufacturer, I'm just selling" usually doesn't protect against patent claims, what rights need to be verified, and how to reduce the risk of having your product page blocked. In this video: — What is patent purity; — Why a product seller can also be liable for patent infringement; — How patent purity differs from patentability; — What rights need to be verified before launching a product; — Why inventions, utility models, industrial designs, and trademarks are important; — Why verification is always tied to a specific territory and date; — How to verify complex products and individual components; — How products are compared with patents and trademarks; — When is a patent purity check especially necessary; — When such a check may be unnecessary; — What to do if a risk is discovered during the check. ▶ Watch the full course:    • Курс "Патентование для бизнеса"   Video navigation: 00:00 — Why marketplaces block patent cards 01:30 — Why the seller responds even if they are not the manufacturer 02:09 — What is patent purity 03:09 — What rights need to be checked: technical solutions, design, and trademarks 04:19 — Features of patent purity: territoriality, date, comprehensiveness 06:23 — How a patent purity check is conducted 08:22 — When a check may be unnecessary 10:00 — Possible consequences of an error 10:48 — What to do if there is no patent purity For questions about patent services and consultations: ✉ [email protected] 📞 +7 (499) 394-38-09, +7 (926) 714-66-07 WhatsApp / Telegram / Max: +79267146607 Our website: https://www.start-patent.ru Telegram channel: https://t.me/startpatent Our team will be happy to help you understand all the intricacies of patenting and protect your intellectual property.
