General Remarks

We may only represent applicants who are citizen of a member state of the European Patent Convention (EPC) or having its residence or place of business in a member state of the EPC.

For obtaining one or more patents on an international patent application (PCT application) it is necessary to enter into a national, e.g. German, or regional, e.g. European, phase before the expiry of a 30 months time limit of the earliest priority date (PCT, Art. 22(1)). For Luxembourg the old time limit of 20 months of the earliest priority date and for Tanzania and Uganda an old time limit of 21 months of the earliest priority date is applicable (status of Nov. 5, 2014). Some states have fixed longer time limits. For a European phase there a 31 months time limit of the earliest priority date.

Costs, required documents and information for entering into a German phase and an European phase can also be obtained on this homepage.

In case you want to speed up the proceeding for one or more states, you may want to enter into the national and / or regional phase(s) long before the expiration of the 30 months time limit and request immediate processing to PCT, Art. 23(2) or 40(2) of the national and / or regional phase(s).
