NTP Incorporated – co-founded by the late Thomas J Campana, who invented many of the technologies used in wireless email – has filed lawsuits against Apple, Google, HTC, LG Electronics, Microsoft and Motorola in the United States District Court for the Eastern District of Virginia. The company says eight of its patents, which relate to the wireless delivery of electronic mail, have been infringed.

NTP is probably best-known for a lengthy legal case with Research in Motion that's now been settled. The US government was forced to intervene after RIM was ordered to stop infringing the patents, which would have shut down BlackBerry email in the United States.

A report today from comScore reveals that iPhone owners consume more mobile media than people with other handsets. (Admittedly some might argue it's not much of a revelation because the iPhone has been designed for this purpose).

The Apple iPhone has just 4% market share in the UK, France, Germany, Spain and Italy, although iPhone users represent 12% of all mobile media users. comScore's report says 94% of iPhone owners use mobile media, 87% use applications and 85% browse the mobile internet. The average for all smartphones is 65% mobile media, 53% web browsing and 53% app usage.

Google has made its Google Voice web-based telephone service available to consumers across the USA. It offers a single number that can reach fixed-line and mobile phones according to the user's preset rules, along with a visual interface for voicemail and free calls within the US & Canada. The service had previously only been available to invited guests. Google Voice is currently free except for international phone calls.

Apple's new terms of service for application developers (released this week) appear to prohibit iPhone developers from sharing advertising data with AdMob and its new owner Google.

Although an "independent advertising service provider whose primary business is serving mobile ads" is permitted access to user data, others – such as "an advertising service provider owned by or affiliated with a developer or distributor of mobile devices, mobile operating systems or development environments other than Apple" – would not be allowed.
