As a member of the Paris Convention, complete applications may claim priority to local or foreign applications within 12 months of the earliest priority date and as a member of the Patent Cooperation Treaty, the patent office accepts national phase applications up to 34 months from the earliest priority date.

Trade marks

The trade marks office accepts applications for trade marks in relation to goods and services as well as certification and collective trade marks. A trade mark is viewed as any sign capable of being represented graphically and may include word marks, device, patterns, signatures, sounds etc.

Both functional and aesthetic designs may be registered in South Africa. The deadline for claiming priority from a foreign design application is 6 months from the priority date.
