NEW YORK Inventor Judah Klausner's company has clinched technology license agreements with Yahoo, Panasonic, Avaya Inc and Qwest Communications, ending its legal battles with those companies.
Klausner Technologies Inc had sued the four companies and other big technology firms for infringing patents covering visual voicemail, which shows who has left voicemails and allows phone users to choose which messages they want to hear.
Klausner, which already has licensing agreements with companies such as Apple Inc and Google, said on Thursday that it was still engaged in legal cases against BlackBerry maker Research In Motion and Cisco Systems.
Qwest, a telecommunications service provider, was bought by CenturyLink Inc earlier this month. Avaya Inc is a privately held provider of telecommuniations equipment.
