Patent Rights

Patent Rights refer to the exclusive rights granted by a state to an inventor or their successor in title for a limited period, as a type of intellectual property. In foreign trade, patent rights are a core subject matter in technology trade, licensing, and joint ventures, often involving patent licensing, patent assignment, infringement litigation, and customs intellectual property protection. Usage scenarios include: when exporting products containing patented technology, it is necessary to confirm whether authorization from the patent holder has been obtained to avoid infringement; importers requiring suppliers to provide patent certificates or authorization letters; stipulating patent ownership, licensing scope, territorial restrictions, and infringement liability in contracts. Precautions: Patent rights are territorial and valid only in the granting country, so the patent status in the target country must be checked before export; patent rights have a time limit and enter the public domain upon expiration; it is necessary to distinguish patent rights from trademark rights and copyrights—the former protects technical solutions, while the latter protect signs or works. Unlike Know-how, patent rights require disclosure of technical content in exchange for protection, whereas Know-how is kept confidential. Foreign trade practitioners should emphasize patent searches and FTO (Freedom to Operate) analyses to prevent infringement risks.
