In June 2021, S&Z became the third largest patent law firm in South Africa.

Most South African patent firms are filing applications electronically, with S&Z adopting a new patent filing and management system that significantly increased efficiency of South African patent filings and reduced costs. 2021 will likely see stiff competition for market-share based on cost.

Why extend your patent to South Africa?

The deadline for filing South African national phase patent applications is 34 months (free extension offered by GlobalIPCo). Since South Africa does not examine patent applications, grant typically takes 12 months at a total cost of $469 (discount available to attorneys).
