It is not enough to have filed and / or registered a mark to be safe from possible counterfeits. The trademark must be watched to make sure others do not attempt to register an identical or similar trademark. So, if that happens, you can stop the attempt. In fact, often the owners of trademarks notice identical or similar marks only after many years from their registration and/or use. This almost always involves having to bear quite high legal costs in order to assert their rights.
It is possible to monitor a registered trademark in every country of the world and the costs of monitoring are extremely limited.
It’s better to take into account that the watching of a trademark is the only possible assurance on it.
