Opposition (Q25-Q30)
25. Q: What is the valid period for filing an opposition?

An opposition should be filed within three (3) months from the date of publication of a preliminarily approved trademark. (For example, if a trademark is published on March 7, 2000, an opposition, if any, should be filed before June 6, 2000.)
No extension of time can be obtained for filing an opposition.
