FAQs
1. What is the typical patent term for pharmaceutical patents in Mexico?
Pharmaceutical patents in Mexico generally have a 20-year term from the filing date, subject to maintenance fees.
2. Can MX2011008922 be challenged for invalidity?
Yes, patents in Mexico can be challenged via legal proceedings citing lack of novelty, inventive step, or inventive activity, often through opposition or nullity actions.
3. How does this patent protect against biosimilar or generic entrants?
Claims that cover specific compounds or formulations can prevent generic equivalents from entering the market without licensing or infringing the patent.
4. Are there restrictions on patenting pharmaceutical processes in Mexico?
Yes, processes involving methods of treatment or surgical procedures are generally not patentable; however, manufacturing processes or chemical synthesis methods are protected.
5. How does the patent landscape influence drug pricing in Mexico?
Patents confer exclusive rights, often leading to higher prices due to lack of competition; patent expiration opens the market for generics, reducing prices.
