NeoMedia Technologies patented the technology behind camera phone barcode scanning a decade ago and they are in current litigation with ScanBuy, who saw their copyright infringement charges against NeoMedia dissmissed last year. Currently NeoMedia's Patent Infringement counter-suit against ScanBuy remains pending and will undoubtably be upheld later this year.
NeoMedia has thus far won copyright infringement cases brought against Virgin Entertainment, LScan, and AirClick.
