How can i protect trademark around the world?
If you want to protect your trademark around the world you should keep in mind one thing - trademarks are territorial. The registration of your trademark in one country doesn’t mean protection in the whole world. If you want your mark protected worldwide you have to register it in each country of the world but this is such an expensive and long process.
The most cost-effective decision will be the registration of your mark in the countries where you already have or plan to have your business.
Also, there are some opportunities for those who want to register their brand in the European Union countries - a EU trademark which includes the registration of your mark in all 28 European Union countries. One more advantage is that applying for a EU trademark is much cheaper than for each EU country separately. But you should remember that your registered trademark must be used in commerce, otherwise, it can be canceled.
