Neither Apple nor Unwired Planet immediately responded to a request for comment. Google declined to comment, beyond noting that it has not as of yet been served with the lawsuit papers.

Unwired Planet is requesting a jury trial for both cases.

Prior to changing its name to Unwired Planet earlier this year, Openwave focused on providing technologies for mobile handsets. It pioneered early mobile data technologies such as the widely used WML (Wireless Markup Language) and WAP (Wireless Access Protocol). Founded in 1994, the company has changed its name several times, and has been known as phone.com, Libris and Unwired Planet (now twice). The company went public in 1999, and for its fiscal 2001 reported more than US$465 million in revenue. In recent years, however, Unwired Planet's revenue has fallen dramatically, prompting it to look for additional sources of income, such as patent licensing. For fiscal 2012, which ended in June, the company reported revenue of $15.05 million, all from its patents.
