First, a five-phase lifecycle view of the supply chain is presented, tracking how risks shift from design to procurement, manufacturing, distribution, and sales. The following sections apply the framework to the five phases of the supply chain, integrating real-world cases handled by Jiaquan IP Law with broader industry lessons. Phase 2: Procurement – detecting hidden risks in supply networksProcurement is a critical vulnerability where counterfeit goods, infringing components, and supplier opportunism can undermine an entire supply chain. Effective detection requires forensic testing, supplier audits, contractual IP warranties, and monitoring of supplier IP activity. This confirms the need for companies to record rights with customs, supply authorization documents, and work closely with logistics providers.
