Plant Variety Protection

Chang Tsi & Partners provides full-cycle legal services for plant variety protection (PVP) for breeding companies, research institutions, and individual breeders across Mainland China, Hong Kong SAR, Macao SAR, and Taiwan. We have completed qualification registration with the Ministry of Agriculture and Rural Affairs (MARA) and the National Forestry and Grassland Administration (NFGA), and are authorised to handle variety rights applications for both agricultural and forestry plants. Drawing on our law firm credentials, we also provide comprehensive support in dispute resolution, litigation, and legal advisory.
     
Plant variety protection involves a unique intersection of technical and legal disciplines—DUS testing (distinctness, uniformity, stability) is the core component of variety rights examination, the management and submission of propagating material directly impacts the application process, and seed industry compliance (seed production and marketing permits, variety approval and registration, labelling compliance, import/export quarantine) constitutes a critical legal need for seed enterprises. Our team provides professional legal guidance across all of these areas.
