When should we register a trademark?

You want to register your trademark AS SOON as you realize that you would fight not to lose it. The cost of registration will be negligible compared to the cost of having to prove in court that your brand is your brand. A registered trademark pushes the burden of proof onto the other side, so it would make it very expensive to prove that your trademark is not rightfully yours.

We published two cartoons about this:

Hope it helps,
