MoneyGram has won an appeal against a patent infringement judgement that saw it ordered to pay rival outfit Western Union $16.53 million.
Western Union filed a suit in May 2007, claiming MoneyGram Payment Systems' "FormFree" offering infringed patents related to its own "Money Transfer By Phone" service.
Last September a federal jury in Texas awarded Western Union $16.53 million in damages from its smaller rival.
However, MoneyGram says that the United States Court of Appeals for the Federal Circuit has now issued a ruling in its favour.
According to a statement, the court found that "on the grounds of obviousness, certain patents relating to enabling customers to send transactions without the use of written send forms were invalid".
