4 Tech Stock Stories Causing Tuesday Turbulence

Google Inc. (NASDAQ:GOOG): Closing price $896.57

On Tuesday, Motorola Mobility told a United States appeals court in San Francisco that a Microsoft Corp. patent that caused an import ban on its phones is the “poster child” for general ideas being applied to new devices and then labeled an invention. Attorney Charles Verhoeven of Quinn Emanuel in San Francisco said that, “Simply saying ‘on a mobile device’ is not an invention” — and that Microsoft’s patent for a manner in which phones synchronize calendars with computers is not really different from techniques employed by the failed Newton personal digital assistant of the 1990s by Apple or Microsoft’s desktop software.

Motorola Mobility ants to invalidate the patent that it admits it has infringed. The International Trade Commission in Washington issued an import ban in May last year after finding that Motorola Mobility devices infringed the patent.
