The whole deal is rather complicated, because Klausner Technologies filed a patent lawsuit under its visual voicemail patents against Apple and others last year, claiming that Apple’s iPhone Visual Voicemail infringes Klausner Technologies’ U.S. Patents 5,572,576 and 5,283,818. The tricky part is that these patents were already licensed to other companies providing visual voicemail, including AOL, Vonage Holdings, and many others.
Even better(or worse, depends how you look at it), Klausner Technologies claimed that Apple's Newton was covered under an OEM patent license granted by Judah Klausner, the company's founder, over 20 years ago, under his landmark US Patent 4,117,542.
So...what next? I have no idea, to be honest, but I guess they will settle things off-court. What do you think?
