Shatterprufe (Baker Street Trust): frequently asked questions
What should Shatterprufe (Baker Street Trust) consider for its trademarks?
- Where to file next: its goods sell strongly in Zimbabwe, Tanzania and Nigeria – markets where South African exports of the same goods are large or growing, and where S&Z files at its own all-in prices (see “Shatterprufe (Baker Street Trust) – relevant export countries”).
- Fewer new brands: new brand names fell from 2.2 to 0.2 a year – worth reviewing whether planned launches are being protected early enough.
- Renewals and use: keep track of the ten-year renewal dates and of marks that are no longer used – unused marks can be challenged after five years, and some may no longer be worth renewing.
