How many trademarks can a single company have?

Trademark in Vietnam

However, there are some point to have in mind:

The registration of highly similar trademarks is a waste of time and money. The trademark is protected not only against the use of Identical marks, but also against the use of similar Marks. So if you use the trademark in three different colours, you should register only black-and-white trademark, as the protection will be given to all the colourful uses of the mark.

Review your trademark portfolio from time to time. Some trademark might not be relevant anymore. So you should not renew the marks and pay all the renewal or registration fees for such marks that no longer exists in the market.

The more different trademarks you own, the stronger competitive power you have. You can limit the possibility of your competitors to use in all the brand names and similar names that you have the registration. So the broader TM portfolio is, the less choices are left to the competitors. Also, if you lose one trademark later on, it will not be a tragic situations, because you will have other protected marks. However, if you have a single mark registered and someone cancels it, you will be in very unfavourable situation.

The trademark is registered only in a country where you filed the registration. Which means, if you have a US trademark, you still do not have any protection in the EU market. If you want to have protection in EU, you must file a new European application.
