A German court ruled that several Motorola tablets and phones had infringed a method for apps to handle different kinds of user input. Samsung, HTC and others pay a licence to use the technology, but Motorola had resisted.
Google now faces additional sales restrictions on its products in Germany unless it makes significant changes to its Android operating system. It marks the third lawsuit Microsoft has won over Google in recent months in the country.
"We’re pleased this decision builds on previous rulings in Germany that have already found Motorola is broadly infringing Microsoft’s intellectual property," said Microsoft’s deputy general counsel David Howard.
"We will continue to enforce injunctions against Motorola products in Germany and hope Motorola will join other Android device makers by taking a licence to Microsoft’s patented inventions."
A statement from Google said: "We are waiting for the written decision and are evaluating our options, including an appeal."
