  • Combe International Ltd v Dr. August Wolff GmbH & Co. KG Arzneimittel [2020] SGIPOS 3 in which Ruby represented the registered proprietor, Dr August Wolff of the “VAGISAN” mark in an invalidation action brought by Combe International based on its “VAGISIL” mark. Ruby is also acting in the appeal which is pending before the High Court.
  • Teraoka Seiko Co., Ltd v Digi International Inc. [2020] SGIPOS 1 in which Ruby assisted in the successful opposition by Teraoka Seiko to Digi’s application for a similar mark in respect of goods and services related to the Internet of Things (IoT).
  • Ozone Community Corp v Advance Magazine Publishers Inc [2010] SGHC 16 in which Ruby represented Ozone Community Corp in the Trade Marks Registry, High Court and Court of Appeal, where she successfully secured the registration of Ozone’s “HYSTERIC GLAMOUR” trade mark.
  • Pierre Fabre Medicament v Dabur Pharma Limited [2009] SGIPOS 15 in which Ruby successfully represented Pierre Fabre in opposing Dabur’s trade mark application for the “VINELBINE” trade mark. This was a landmark decision as this was the first time that a local tribunal considered the issue of whether a brand which was similar to an International Non-Proprietary Name (the active ingredient “VINORELBINE” in this case) could be registered as a trade mark.
