RENO, Nev. -- January 10, 2013

Unwired Planet, Inc. (NASDAQ: UPIP) (“Unwired Planet” or the “Company”), the
inventor of the mobile Internet, today announced that it has entered into a
patent purchase agreement with Ericsson (NASDAQ:ERIC) whereby Ericsson will
transfer to Unwired Planet 2,185 issued US and international patents and
patent applications.

The transferred patents significantly broaden Unwired Planet’s Mobile
Internet-focused portfolio and include 753 United States issued patents
related to 2G, 3G and LTE technologies. Under the terms of the transaction,
Ericsson will also contribute 100 additional patent assets annually to Unwired
Planet commencing in 2014 through 2018. Unwired Planet will compensate
Ericsson with certain ongoing rights in future revenues generated from the
enlarged patent portfolio. Unwired Planet will also grant Ericsson a license
to the Company’s enlarged patent portfolio.

The combined portfolio reflects decades of significant investment in research
and development and the companies’ respective roles as pioneers in the
development of technology critical to Telecommunications Infrastructure and
the Mobile Internet. The contributed Ericsson portfolio includes patented
inventions relating to global telecommunication technologies, such as GSM,
GPRS, EDGE, WCDMA and LTE, as well as many other patented inventions that are
widely implemented in many popular wireless devices and mobile industries.

Following the transaction, Unwired Planet will execute a strategy as a
long-term industry platform for the realization of intellectual property value
across the global telecoms and mobile handset markets.

“Ericsson and Unwired Planet teamed in the late 1990’s at the dawn of the
mobile Internet to define an industry and develop technology at the cutting
edge of mobile communications. Our mobile heritage reflects decades of
pioneering new technology, supported by billions of dollars in research and
development. Our inventions have delivered massive social value and this
transaction with Ericsson reflects our commitment to protecting and realizing
value from this innovation,” said Mike Mulica, Chief Executive Officer of
Unwired Planet. “We look forward to leveraging a strong, multi-dimensional
patent portfolio and furthering discussions with key industry players who are
interested in licensing these inventions to protect and further build their
product strategies.”

“In 1997, Ericsson and Unwired Planet introduced the Wireless Application
Protocol that brought Internet access to mobile devices,” said Kasim Alfalahi,
Chief Intellectual Property Officer, Ericsson. “Following this transaction,
Unwired Planet’s portfolio will reflect decades of invention at the forefront
of mobile infrastructure, handset technologies and over-the-top services. We
are pleased to have concluded this business deal with Unwired Planet as an
alternative channel for IP licensing.”

Further details of the transaction are included in a Form 8-K to be filed by
Unwired Planet with the United States Securities and Exchange Commission.
