Covarrubias’ life sciences and plant varieties group comprises biotechnologists, pharmaceutical chemists and biochemists, who routinely work alongside the firm’s lawyers. On the regulatory side, the team advises on healthcare-related registrations, as well as the medical-device and food sectors. Patent prosecution is another core strength. Managing partner Arturo Covarrubias is sought out by pharmaceutical and biotechnology corporations to lead patent invalidation and defence actions before Chile’s National Institute of Industrial Property (INAPI) and Industrial Property Court (TDPI). Beyond litigation, Covarrubias’ life sciences and plant varieties practice covers regulatory issues, market access, and the protection of biological and chemical inventions. Providing key support, biochemist and patent group head Matías Valenzuela assists with chemical, pharmaceutical, and biotechnological sector-related protection strategies; promoted to partner in January 2026, his recent experience includes successfully defending a major pharmaceutical client’s invention patent against a nullity action. At associate level, Gabriel Vargas assists with structuring research and development (R&D) agreements and technology transfer protocols for biotech start-ups and research centres.
