Telstra has revealed the addition of almost one million new mobile services in the six months to December 2011, but Sensis revenues plummeted 24 percent in 12 months.
Apple & AT&T have both been hit with patent infringement claims over the iPhone's Visual Voicemail feature that lets users see the full list of voicemail messages on screen and listen to them in any order.
The suits have been filed by the California law firm of Dovel & Luner in a federal court in the Eastern District of Texas on behalf of Klausner Technologies, a company founded by Judah Klausner, the inventor of the PDA and electronic organiser. They relate to Klausner's US patents 5,572,576 and 5,283,818, which, Klausner claims, have already been licensed to various other companies that provide visual voicemail including Time Warner's AOL for its AOL Voicemail services, Vonage Holdings for its Vonage Voicemail Plus services and others.
Greg Dovel of Dovel & Luner claimed that: "With the signing of each new licensee, we continue to receive further confirmation of the strength of our visual voicemail patents." Klausner says it estimates its claims against each of Apple and AT&T to be worth $US360 million based on damages and estimates future royalties. However it has separately filed suits against Apple & AT&T to the same value.
There were suggestions at the time of the iPhone's launch back in January that Apple was heading for trouble with its visual voicemail feature, but from Citrix, not Klausner. The Register UK reported that Citrix had been selling Visual Voicemail software since it acquired Net6 in 2004.
According to Wikipedia visual voicemail technology is used by a number of operators and on a number of devices. "In recent months, several companies in the telecommunications space have integrated a visual element into their voicemail services. The most prominent services to offer this are AT&T Mobility with Apple's iPhone, CallWave's cross-platform Mobile Visual Voicemail and SimulScribe's SimulSays for BlackBerry and Windows Mobile devices. Visual Voicemail-type services are delivered by companies such as SimulScribe, CallWave, GotVoice, PhoneGnome and GrandCentral.
