Pre-existing trademarks are protected against usurpation by geographical indication under section 19(2), which states:
"(2) Where a trademark has been applied for or registered in good faith, or where rights to a trademark have been acquired through use in good faith either:
(a) before the date of entry into force of this Act; or
(b) before the geographical indication is protected in its country of origin;
this Act shall not prejudice the registrability of or the validity of the registration of a trademark, or the right to use a trademark, on the basis that such a trademark is identical with, or similar to, a geographical indication."
