Klausner Technologies and Apple. iPhone's Visual Voicemail System.
At December 5th of this year Klausher Technologies Company gave a lawsuit on 360.000.000$. The reason was Visual Voicemail, which included iPhone.
For understanding this question you may looking to the picture on the right. If you have a iPhone, Visual Voicemail enables you to look over a list of voicemails and choose what message to listen now. And one of the main advantages of this system is possibility directly moving to message that you want, without needing to sift through prior messages.
Klausner Company in it’s suit saying that Apple's Visual Voicemail infringes upon a some patents. They perfectly knew what is needed to do. U.S. Court for the Eastern District of Texas is well-known as body, which have jury, that given a high priority of success to patents owners. And Klausner Technologies filed its lawsuit there.
This was not a first example of Klausher’s and Apple’s confrontation in the court. In the 1990s the first one sued Apple over different patents involving the Apple Newton. Eventually, some time later Apple agreed to a licensing deal with Klausner and this suit was closed.
For today this question was ended on the words of Greg Dovel - plaintiff by the California law firm Dovel & Luner: "We have litigated this patent successfully on two prior occasions”. And it’s said in the statement of Klausner.
