Further to our previous articles on this website, in which we reported that that the Chilean Law on Industrial Property was finally enacted on 1 December 2005, we can now confirm that the revalidation of foreign granted patents is no longer possible under the new law, as a requirement of absolute novelty has now been introduced. Other provisions of importance in the new law include the broadening of the definition of patentable subject matter and the extension of the term of a patent from 15 years calculated from the registration date to 20 years calculated from the filing date. Annuities are now payable for consecutive ten-yearly periods, after a patent application has been accepted. These provisions apply only to patent applications filed after the date of introduction into force of the new law (1 December 2005). Please let us know if you have any questions in this regard.
