The failure of the billionaire’s ice cream chain to win its ‘Blizzard’ dispute shows that a formidable IP enforcement strategy still needs to be backed by solid evidence, finds Muireann Bolger.

Owners of large brands have the might and means to assail smaller companies with a flurry of lawsuits if they detect any sign of trademark infringement and/or dilution.

This week, it emerged that US office supplier WB Mason prevailed against Warren Buffett’s American Dairy Queen (ADQ), after a district court of Minnesota ruled that it had not infringed by using the Blizzard name on its bottled spring water.
