I have developed 2 electronics products and the manufacturer is in China. I will sell them to some importers/distributors in many countries. Some of them will maybe sell my products with their own brand, some maybe with mine.
My question is, should I invest money to register a trade mark in EU and North America, or it's not necessary?
BTW, how to find customers when you are exporter? Contact many companies which could be interested in each targeted country by email first? Any better options?
