(Reuters) - Memory card and MP3 music player producer SanDisk said on Thursday a legal battle with MP3 patent holders is ongoing and shrugged off a statement from a patent pool firm claiming a judicial victory.
Sisvel from Italy which collects royalties for audio coding technology used in MP3 players and set top boxes -- also on behalf of other firms like Philips Electronics (PHG.AS) from the Netherlands and France Telecom (FTE.PA) -- has accused SanDisk of not paying for the technology, reports Trend.
SanDisk's MP3 players were seized by German law enforcement agencies at the IFA electronics trade show in Berlin in September.
Sisvel said in a statement that a judge in the German regional criminal court of Berlin had ruled last week that the seizure had been legal and that there had been sufficient grounds for suspicion of deliberate patent infringement.
A Sisvel spokesman said the judge had only ruled on the legality of the seizure, and not on the infringement itself.
SanDisk said it uses different technology and believes it does not have to pay royalties to Sisvel and its partners.
"In a litigation currently pending in the Mannheim District Court, SanDisk is showing that its MP3 players operate a technology which is completely different from a certain audio data transmission and reception techniques that has been patented for Philips (PHG.AS) and others many years ago," SanDisk said in a statement.
"An expert opinion from one of the founders of MP3 digital audio compression substantiates SanDisk's position. SanDisk is not infringing any patent in the pending litigation," it added.
A SanDisk spokeswoman in Europe said a ruling was expected in March or April next year.
SanDisk, which is a distant second to Apple (Nasdaq:AAPL - news) in the digital music player market, is the world's leading maker of flash memory data storage cards used in digital cameras and mobile phones as well as MP3 players.
