Which South African patent law firms filed the most provisional patents in 2020?

Surprisingly, 2020 didn’t see a significant drop in the number of South African provisional patents filed. Although, the South African Patent Office was closed for a few months during lockdown, the decline in provisional patents simply continued its gradual negative trend.

Adams & Adams remains the top filer of South African provisional patents, S&Z retained its second place for a second year running, while Spoor & Fisher was pushed down another notch, this year by Hahn & Hahn.
