InterDigital Repositions Organization to Sharpen Focus on Core Wireless
Technology Opportunities; Company Expects to be Cash Flow Positive for Full Year
2004

     KING OF PRUSSIA, Pa.--(BUSINESS WIRE)--April 16, 2004--InterDigital
Communications Corporation (Nasdaq:IDCC), a leading architect, designer and
provider of wireless technology and product platforms, today announced an
internal corporate repositioning to sharpen the Company's focus on technology
opportunities closely aligned to its core competencies as an innovator of
wireless technologies. This repositioning will simultaneously enhance
operational efficiency. As part of this repositioning, the Company has reduced
its global employee work force by approximately 8%, or 25 employees.
     "Our strategic focus has always been centered on the creation and
monetization of highly valuable technology and intellectual property (IPR) that
drives innovation in the wireless industry. To strengthen that focus and ensure
that we are increasingly efficient as a developer of fundamental wireless
technology, we are making operational adjustments to our workforce and
increasing the relative mix of people dedicated to IPR-rich technology
development. We are also reducing our internal investment in the development of
technology elements that have little or no opportunity to differentiate us
through the incorporation of inventive content," said Howard Goldberg, President
and Chief Executive Officer.
     "This adjustment in strategic emphasis reflects our ongoing commitment to
position InterDigital for long-term value creation. We are now more intensely
focused on our differentiated ability to conceptualize and invent new wireless
technology solutions, develop those technologies for commercial application and
license them to equipment producers worldwide. We expect our technology
development programs to continue to enable product options which we will bring
into the marketplace for specific customers and partners. As we focus our
development activities, we are making necessary changes to the mix of skills in
our internal engineering team. In making those changes, we are fully preserving
our ability to respond to targeted opportunities to develop technology and
wireless component products and serve as a value-added partner to equipment
producers," he concluded.
     The work force reduction affects primarily software and implementation
design engineers in the King of Prussia, Pennsylvania and Melville, New York
facilities. As part of the operational improvement, the Company will close its
Munich, Germany office.
     In second quarter 2004, InterDigital expects to record a pre-tax
repositioning charge of approximately $0.7 million, which is primarily related
to severance and other cash benefits associated with the workforce reduction.
     InterDigital expects to be cash flow positive for 2004. The Company expects
annualized pre-tax cost savings of approximately $3.1 million associated with
the repositioning. For 2004, the Company anticipates benefits of approximately
$2.2 million.
     InterDigital will release its first quarter 2004 operating results and hold
its quarterly conference call on May 10, 2004.
