If one country opposes your trademark application, it generally does not result in the forfeiture of your entire trademark application. Oppositions to trademark applications are typically handled on a country-by-country basis, meaning that the opposition will apply to the specific country where the opposition was filed.
Trademark oppositions occur when a third party believes that your trademark application conflicts with their existing rights or is not eligible for registration based on certain grounds. The opposition process allows the opposing party to present their arguments and evidence to the trademark office, explaining why they believe your application should be refused.
If an opposition is successful in a specific country, it means that the trademark application may be refused or rejected in that country. However, it does not automatically affect the application in other countries where you have applied for trademark registration. The examination and registration processes in different countries are separate and independent.
Therefore, if one country opposes your trademark application, it is important to address the opposition specifically for that country. You may need to respond to the opposition, present counterarguments, negotiate a resolution, or seek legal assistance to protect your rights and continue with the registration process in that specific country. The outcome of the opposition in one country should not impact the applications and registration processes in other countries where you have applied for trademark protection.
