InterDigital Receives Initial Determination in USITC Patent Infringement
Investigation of Nokia, Huawei and ZTE

WILMINGTON, Del., June 28, 2013 (GLOBE NEWSWIRE) -- InterDigital, Inc.
(Nasdaq:IDCC), a wireless research and development company, today announced
that it has received notice that the Administrative Law Judge (ALJ) overseeing
the U.S. International Trade Commission (ITC or Commission) Investigation No.
337-TA-800 of Nokia, Huawei and ZTE has issued an initial determination (ID)
finding no violation of Section 337 of the Tariff Act of 1930. The ALJ found
that one of InterDigital's asserted patents was infringed, but the asserted
claims of that patent were found to be invalid in light of prior art. He
further found that four of InterDigital's patents were not proven invalid but
are not infringed, and that the remaining two asserted patents were invalid
and not infringed.

Importantly, the ALJ indicated that the respondents have not prevailed on any
equitable, FRAND, or license defense. The ALJ also determined that
InterDigital satisfied the domestic industry requirement as to all asserted

"We strongly disagree with the ALJ's determinations with regard to
noninfringement and invalidity. We will petition the ITC for review of the ID,
and we are confident that the strength of our portfolio will, in due course,
result in a favorable outcome," said William J. Merritt, President and Chief
Executive Officer of InterDigital.

InterDigital will promptly file for review by the full Commission. The
Commission has established a date of October 28, 2013 for issuing a final
determination, and has been active in reviewing ALJ initial determinations.

The company will be hosting a conference call to discuss the ID on Tuesday,
