HTC recently made similar claims, unsurprisingly since HTC and Via have worked together multiple times.
The complaint, filed with the ITC and the U.S. district court, claims that all Apple devices using iOS and the A4/A5 processors are infringing on 'microprocessor functionality, namely “method and apparatus for double operand load” (6253312) and “instruction set for bi-directional conversion and transfer of integer and floating point data” (6253311 and 6754810),' said Xbit.
Adds Via:
Via has built up an extensive IP portfolio consisting of over 5000 patents as a result of significant investments in world class technology research and development. We are determined to protect our interests and the interests of our stockholders when our patents are infringed upon.
