All trademark applications go for a 30 day period of opposition where the mark is published in the Official Gazette. This means that anyone (another person or company) can oppose the registration of an application. The trademark opposition process is to give third parties a chance to oppose an application that the trademark office would have otherwise registered.
If you receive a notice of opposition you must respond. If you do not, a default judgment will be entered against you and your application will be canceled or abandoned by the trademark office.
AMD LAW has successfully defended and negotiated settlements of trademark oppositions. For more information about oppositions or to receive a quote, contact AMD LAW at firstname.lastname@example.org.
