In Chile, as most LATAM countries, you have 30 months to file your international PCT patent application, starting to count form the earliest patent priority you claimed.
In Chile, in case you missed this deadline, you have two more months to request a reinstatement of the application. To start this procedure, you will need to pay additional fees, and file a Declaration of Reinstatement of Priority Rights. In this declaration, you have to elaborate on either a non intentional error or the”due care” of the application. The reinstatement is not automatic, and the Chilean patent office can deny it.
If you have a specific concern, please contact us.
