Microsoft is suing Motorola alleging it has infringed
nine patents in its Android phones.
The giant software maker said Motorola phones that use
Google’s Android software are based on Microsoft technology.
The functions include synchronizing e-mail, calendars and
Microsoft filed its lawsuit in a federal court as well as
filing one with the International Trade Commission.
Microsoft said Motorola licensed some of its mobile
technology from 2003 to 2007 but continued to use the technology without
renewing the license.
Its court filing specifically mentions the Motorola Droid
2 and the Motorola Charm smartphones, but Microsoft claims that the
infringements were not limited to those devices.
It is the latest development in a web of legal actions in
the smartphone business.
A Motorola spokeswoman said the company has not yet
received a copy of the suit, but based on its strong intellectual property
portfolio, plans to “vigorously defend itself”.
The suit is the latest in a complicated web of legal actions
between various phone makers and software firms over who owns patents to the
technology used in smartphones.
Nokia began by suing Apple last year, and Apple
subsequently sued handset maker HTC.
Oracle has filed a lawsuit against Google, accusing the
search engine giant of infringing patents on its technology.
Oracle says Google infringed patents on its Java software
while developing its Android operating system.
