20 years from the date of grant
On 21 May 2014, the Brunei Court of Appeal ruled that the “date of patent” under the transitional provisions of Section 115(4)(a) of the Patents Order, should be re-interpreted to mean as “the date of grant.” As a result, patents registered in Brunei under the transitional provisions, originating from Malaysia, Singapore or United Kingdom (including the EU granted patents originating from
the United Kingdom), are now entitled to a term of 20 years from the date of grant of these base patents.
