The Brazilian Patent and Trademark Office has published new regulations which modify the evidentiary and procedural aspects of forfeiture actions against patents and trademark registrations on the grounds of non-working and non-use, respectively.
The provisions common to both patent and trademark forfeiture actions include the following:
2) Evidence of working or use must be submitted by the owner of the patent or the trademark registration within 60 days of the notification; documentation which is illegible or which contains erasures will not be accepted.
3) Forfeiture actions may be withdrawn at any time prior to a decision in the first instance.
In addition to the above, the regulations contain the following provisions relating specifically to patents and trademarks:
1) Forfeiture petitions will only be considered if two years have elapsed since the grant of a compulsory license.
2) It is a defense to a forfeiture action that the patent has been worked in Brazil by the patentee or a licensee whose license has been registered with the Patent Office.
Trademarks
1) Actions may not be filed until 2 years after the date of the registration.
2) The registrant or licensed user of the mark may defend the action by proving that the mark was used
a) within the 2-year period following the date of registration; or
b) within the 2-year period prior to the date the forfeiture action was commenced;
or by showing that there were justified reasons for not using the mark within the required periods.
3) In accordance with a previous regulation, the Brazilian Patent and Trademark Office expressly stated that evidence of use by a licensee may be admissible even though the license has not been recorded against the trademark registration.
