iPhone 4 in new patent suit

A new lawsuit takes aim at the accelerometer- and gyroscope-powered abilities of Apple's iPhone 4, alleging the interactive, 3D input methods are in violation of a US patent, writes AppleInsider.

The lawsuit, filed this week by Triton Tech of Texas, names both Apple and Nintendo as defendants.

Triton is the owner of US Patent number 5 181 181 entitled 'computer apparatus input device for three-dimensional information'.

A federal judge in Arizona has ruled in favour of Taser International in a patent lawsuit that pits the maker of electric-shock devices against a rival company, states Bloomberg Business Week.

US District Court judge Mary Murguia entered a final judgement against Stinger Systems, concluding the company violated Taser's patent on the dual-mode, 'shaped pulse' technology in its electronic control device products.

The court found Stinger's flyback quantum technology in its Stinger S-200 electronic control device infringes on Taser's patent.
