Intellectual Ventures Files Three Patent Lawsuits

Intellectual Ventures, the big investment firm that has bought up 30,000 patents and headed by Microsoft's former chief technology officer Nathan Myhrvold, filed three separate patent infringement suits against nine companies. The three suits cover security software, standard memory and flash memory chips, and field-programmable gate array chips (specialized chips used in products including cellphones, aerospace and defense weaponry, and medical imaging equipment).
