(Trade Mark Protection Act, TmPA)

¹ Where a trade mark is first duly filed in an­oth­er Mem­ber State of the Par­is Con­ven­tion⁵ or with ef­fect in such a Mem­ber State, the ap­plic­ant or suc­cessor in title may claim the date of the first fil­ing for the fil­ing of the same trade mark in Switzer­land, provided the fil­ing in Switzer­land takes place with­in six months of the date of the first fil­ing.

² The first fil­ing in a state that grants re­cipro­city to Switzer­land has the same ef­fect as the first fil­ing in a Mem­ber State of the Par­is Con­ven­tion.
