The Federal Law on the Protection of Industrial Property came into force on 5 November 2020, replacing the former Industrial Property Law. The new law ushers in a host of changes with respect to patents – for example, it clarifies what is non-patentable; impedes the possibility of double patenting; affords new opportunities for obtaining supplementary protection certificates; and includes a Bolar exemption allowing for the import by third parties of patented active drug ingredients for the purpose of conducting tests in the final three years of patent protection. The reform is an important step towards harmonising Mexican IP law with international standards and gives those protecting their inventions in Mexico greater confidence.
