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.

The European Commission has announced a settlement decision in a cartel case that involved ten producers of DRAM memory chips. The fine, which totals €331,273,800 (around £286 million) includes a reduction of 10% for the companies' acknowledgement of the facts. The companies involved were Micron, Samsung, Hynix, Infineon, NEC, Hitachi, Mitsubishi, Toshiba, Elpida and Nanya. Micron was not fined because it revealed the existence of the cartel to the Commission in 2002. Only one of the companies – Infineon – was based in Europe but all sell their products in the European Economic Area (EEA) and must abide by EU law.

Klausner Technologies has filed a lawsuit against HTC, claiming that HTC has infringed its Visual Voicemail patents.

The company owns 25 Visual Voicemail patents in the US, Canada, Europe, Taiwan, Korea and Japan.

Apple has filed a lawsuit against HTC, claiming that HTC has infringed a number of Apple patents related to the iPhone's user interface, underlying architecture and hardware.

The lawsuit has been filed with the US District Court in Delaware and also with the US International Trade Commission, which has the power to block imports of HTC devices if it rules in Apple's favour.
