Motorola Counter-sues Microsoft Over Patents

Motorola has filed a lawsuit against Microsoft, accusing the software giant of violating 16 patents in its Xbox and Windows operating system for PCs, servers and phones.

The lawsuit comes only days after Microsoft filed a lawsuit against Motorola for breaching a contract by overcharging for its patents.

The latest Motorola lawsuit, which was filed in U.S. District Court for the Southern District of Florida and the Western District of Wisconsin, is one of the many mobile phone technology related lawsuits that currently await judgement in US courts.

As the smartphone market grows, companies are using the patents either to slow down rivals or to enforce their own supremacy.

Kirk Dailey, corporate vice president of intellectual property at Motorola Mobility, said in a statement: “Motorola has invested billions of dollars in R&D to create a deep and broad intellectual property portfolio and we will continue to do what is necessary to protect our proprietary technology.”
