Opposition may be filed by any interested party who
considers his rights adversely affected. The term to
file an opposition is 60 days counted from the publication
date. The publication for opposition is made only after
formal examination. The term to oppose a trademark application
can not be extended. Although not necessarily completely
developed, all arguments must be submitted on filing
an opposition.
If an opposition is filed and the applicant does not
take any action before the Office, the applied trademark
is rejected by the office only after studying the merits
of the opposition.
