What is an opposition?
Any person who believes thatits rights would be damaged by the registration of a mark may file an opposition with the Trademark Office within a determined period (depending on the national legislation) after the mark is published for opposition.
The notice of opposition can be based on a trademark application or on an earlier registered trademark. The trademarks can be national (or Benelux) trademarks from the country in which you try to obtain a protection for your trademark.
Earlier trademarks constituting basis for an opposition against a Community Trademark Application can be national trademarks from one of the Member States of the European Union (national), international trademarks (registered under the Madrid Agreement and Protocol) or trademarks from the Benelux Trademark Office.
Before certain registers (in particular the Community Trademark Register) it is also possible to base opposition on well-known trademarks protected under Article 6 bis of the Paris Convention (an International Agreement relating to Industrial Property Protection). Finally, opposition can also be based on earlier rights within the EU that are not just applicable to particular localities, provided that the national law governing these rights allows the proprietor to prohibit the use of a subsequent trademark.
