     InterDigital Announces First Quarter 2007 Financial Results

             Strong Profitability and Cash Flow in Quarter

    KING OF PRUSSIA, Pa.--(BUSINESS WIRE)--May 8, 2007--InterDigital
Communications Corporation (NASDAQ:IDCC) today announced results for
first quarter ended March 31, 2007. Highlights for the first quarter
include:

    --  Revenue of $67.8 million, including $58.5 million of recurring
        revenue

    --  Net income of $17.7 million, or $0.34 per diluted share

    --  Free cash flow(1) of $93.3 million

    --  Repurchase of 4.5 million shares of the company's common stock
        for $147.6 million

    William J. Merritt, President and Chief Executive Officer, stated,
"First quarter 2007 was another good quarter for InterDigital.
Recurring royalties from our core base of existing licensees were
strong, growing significantly both sequentially and on a comparable
quarter basis. We also drove substantial additional earnings through
incremental royalties identified in a routine audit. Further, we
continued to protect our intellectual property, as evidenced by the
actions brought against Samsung in April 2007. We continue to have
dialogue with unlicensed manufacturers and remain focused on growing
our base of 3G licensees."

    "Our product programs also progressed very well," continued Mr.
Merritt. "We are on target to have a dual-mode 2G/3G HSDPA/HSUPA modem
ASIC available in engineering samples by late summer 2007, making
InterDigital one of only a few companies in the world with commercial
terminal unit ASIC products with functioning HSDPA and HSUPA
technologies."

    In addition, in April 2007, the company completed its $350 million
share repurchase program. That program began in March 2006 with the
Board of Directors authorization of $100 million in repurchases which
expanded to $200 million in May 2006 and $350 million in December
2006. Over the course of the program, the company repurchased 11.3
million shares, or approximately 20 percent of the shares outstanding.
Since 2003, InterDigital has expended $436 million repurchasing 16.3
million of its shares.

    First Quarter Summary

    Revenue in first quarter 2007 increased to $67.8 million from
$51.6 million in first quarter 2006. First quarter 2007 revenue
included $58.5 million of recurring patent license royalties and
technology solution sales as well as $9.3 million associated with
prior period sales of Sony Ericsson's covered 2G products identified
in a routine audit. Recurring patent license royalties in first
quarter 2007 increased 16 percent to $57.5 million from $49.6 million
in first quarter 2006. This increase was due largely to higher 2G
royalties from Sony Ericsson, 3G royalties from Panasonic, and a full
quarter's amortization of patent licensing revenue related to an
agreement with LG. Technology solution revenue decreased to $1.0
million in first quarter 2007 from $2.0 million in first quarter 2006
due to the completion of deliverables under an agreement with General
Dynamics and the timing of milestone achievements under a development
agreement with NXP. Licensees that accounted for 10 percent or more of
the $58.5 million of recurring patent license royalties and technology
solution sales were LG (24 percent), Sharp Corporation of Japan (18
percent), NEC Corporation of Japan (16 percent), and Sony Ericsson (15
percent).

    The company's net income in first quarter 2007 increased to $17.7
million, or $0.34 per diluted share, from $12.9 million, or $0.23 per
diluted share, in first quarter 2006. This improvement in net income
was driven by higher revenues offset, in part, by increased operating
expenses.

    First quarter 2007 operating expenses of $43.6 million increased
33 percent when compared to first quarter 2006. This increase
primarily resulted from higher costs related to (i) the company's
acceleration of planned expenditures associated with the development
and fabrication of its dual mode 2G/3G ASIC and related PC card
reference platform (ii) overlapping incentive compensation plans as
well as normal inflation and vacation accruals, and, (iii) increased
patent litigation and arbitration activity. Patent litigation and
arbitration expenses increased to $5.5 million, net of a $1.7 million
insurance recovery, in first quarter 2007 from $3.8 million in first
quarter 2006.

    Net interest and investment income of $2.6 million in first
quarter 2007 increased $1.1 million over first quarter 2006 due mainly
to higher investment balances in first quarter 2007.

    The company's first quarter 2007 effective tax rate was
approximately 34 percent, which takes into account estimated future
tax credits related to 2007 research and development activity. In
first quarter 2006, the company's tax expense included amounts related
to both U.S. statutory federal taxes and foreign withholding tax
payments made in prior years resulting in an effective rate of
approximately 36%.

    During first quarter 2007, the company generated $93.3 million of
free cash flow due largely to the receipt of a $95 million payment
from LG related to its patent license agreement.

    Near-Term Outlook

    Richard J. Fagan, Chief Financial Officer commented, "Consistent
with the company's practice, revenue guidance for second quarter 2007
will be provided following the receipt and review of applicable
royalty reports. Notwithstanding that fact, the reports we have
received to date (which include all of our major licensees) reflect a
trend of strong sales.

    "We currently anticipate that second quarter 2007 operating
expense growth, excluding patent arbitration/litigation costs, will
slow to roughly one third of that experienced between the most recent
two quarters," added Mr. Fagan. "Beyond second quarter 2007, we
anticipate that the quarterly level of expense for product programs
should level off for the remainder of the year, as we will have
reached the level of capability needed to pursue the fabless business.
Further increases in costs would likely be customer specific
acquisition costs that would also be accompanied by revenue.

    "Further, we also currently expect that our patent arbitration and
litigation expenses in second quarter 2007 will be above the $7.2
million (excluding an insurance recovery) experienced in first quarter
2007," continued Mr. Fagan. "The actual level of expense will depend
on the level of activity we experience during the quarter including
any activities associated with newly filed cases involving Samsung in
the U.S. District Court and the U.S. International Trade Commission.
Lastly, our book tax rate throughout the balance of 2007 will be
dependent upon our estimates of the relative proportions of our full
year profitability and level of investment tax credits in 2007, but is
currently estimated to be a 34 percentage effective rate."

corporate bonds. Management views these instruments to be near
equivalents to cash and believes that investors may share this
viewpoint.

    (1) InterDigital defines "free cash flow" as operating cash flow
less purchases of property and equipment and investments in patents. A
detailed reconciliation of free cash flow to GAAP results is provided
at the end of this news release.

    (2) InterDigital adopted FASB Interpretation No. 48 (FIN 48) on
January 1, 2007. Upon adoption, a $2.1 million reserve for uncertain
tax positions was established. Consistent with FIN 48, the beginning
balance of retained earnings was reduced by the $2.1 million increase
in reserves.
