The Supreme Court of the Philippines has canceled two trademark registrations for the "Lido" brand held by Panciteria Lido Chinese Cuisine Co., ruling that the marks were registered in bad faith. The dispute stems from a split between former business partners who jointly operated the long-established Lido Chinese restaurant under a partnership called Eng Son Co., with one side eventually trading as Lido Cocina Tsina and the other as Salido. The court found that the trademark remains the property of Eng Son Co. — the original partnership — and that the King family heirs who brought the challenge did not automatically become owners of the Lido name, leaving the brand's ultimate ownership unresolved until the old partnership's affairs are formally wound up.
