First, you need to decide where the mark is to be protected. If you apply for a trade mark at the Patent Office of the Republic of Poland under the national procedure, it will be protected in Poland. If you register the trade mark with the EUIPO, it will be protected within the EU. If you want to obtain worldwide protection, choose the international procedure carried out by WIPO.
Before registering a trade mark, always make sure that it does not conflict with other registered trademarks on the market.
The registration proceedings need to be held before a suitable authority, depending on the required area of protection (national, EU, or worldwide). In your application, you must always demonstrate the trade mark in the form in which it will be used on the market.
You can find the precise formal requirements on the websites of the Polish Patent Office, EUIPO, and WIPO. Should you have any doubts, contact a patent attorney for a consultation.
