             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Participants and Plan Administrator
InterDigital Communications Corporation Savings and Protection Plan

         We have audited the accompanying  statement of net assets available for
benefits of the InterDigital  Communications  Corporation Savings and Protection
Plan as of December  31,  2003,  the related  statement of changes in net assets
available  for benefits for the year ended  December 31, 2003.  These  financial
statements are the responsibility of the Plan's management.

         We  conducted  our audit in  accordance  with  standards  of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain  reasonable  assurance about whether the
financial  statements  are free of  material  misstatement.  An  audit  includes
examining,  on a test basis,  evidence supporting the amounts and disclosures in
the  financial  statements.  An audit also  includes  assessing  the  accounting
principles  used  and  significant  estimates  made  by  management,  as well as
evaluating the overall  financial  statement  presentation.  We believe that our
audit provides a reasonable basis for our opinion.

         In our opinion,  the  financial  statements  referred to above  present
fairly, in all material  respects,  the net assets available for benefits of the
Plan as of  December  31,  2003,  and the  changes in net assets  available  for
benefits  for the year then ended,  in  conformity  with  accounting  principles
generally accepted in the United States of America.

         Our audit was made for the  purpose  of  forming an opinion on the 2003
basic financial statements taken as a whole. The supplemental schedule of assets
(held at end of year) as of December  31, 2003 is  presented  for the purpose of
additional  analysis  and is not a  required  part of the 2003 basic financial
statements,  but is  supplemental  information  required  by the  Department  of
Labor's Rules and  Regulations  for Reporting and Disclosure  under the Employee
Retirement  Income  Security  Act of 1974.  The  supplemental  schedule has been
subjected  to the  auditing  procedures  applied  in the audit of the 2003 basic
financial  statements  and, in our opinion,  is fairly  stated,  in all material
respects, in relation to the 2003 basic financial statements taken as a whole.

             Report of Independent Registered Public Accounting Firm

To  the  Participants  and  Administrator  of  the  InterDigital  Communications
Corporation Savings and Protection Plan:

In our opinion, the accompanying statements of net assets available for benefits
and the  related  statement  of  changes in net assets  available  for  benefits
present fairly, in all material respects,  the net assets available for benefits
of  InterDigital  Communications  Corporation  Savings and Protection  Plan (the
"Plan") at December  31, 2002 and for the year then ended,  in  conformity  with
accounting principles generally accepted in the United States of America.  These
financial  statements  are the  responsibility  of the  Plan's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.  We conducted our audits of these  statements in accordance with the
standards of the Public  Company  Accounting  Oversight  Board (United  States).
Those standards  require that we plan and perform the audit to obtain reasonable
assurance   about  whether  the  financial   statements  are  free  of  material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the  amounts  and  disclosures  in  the  financial  statements,   assessing  the
accounting  principles  used and significant  estimates made by management,  and
evaluating the overall  financial  statement  presentation.  We believe that our
audits provide a reasonable basis for our opinion.

Our audits  were  conducted  for the  purpose of forming an opinion on the basic
financial  statements  taken as a whole.  This  supplemental  schedule of assets
(held at end of year) is presented for the purpose of additional analysis and is
not a  required  part of the basic  financial  statements  but is  supplementary
information  required by the  Department  of Labor's Rules and  Regulations  for
Reporting and Disclosure  under the Employee  Retirement  Income Security Act of
1974. This supplemental schedule is the responsibility of the Plan's management.
The supplemental  schedule has been subjected to the auditing procedures applied
in the audit of the basic financial  statements  and, in our opinion,  is fairly
stated in all material  respects in relation to the basic  financial  statements
taken as a whole.

NOTE 1--DESCRIPTION OF PLAN

The following description of the InterDigital Communications Corporation Savings
and Protection Plan, (the "Plan"), is provided for general information purposes.
Participants should refer to the Plan agreement for a more complete  description
of the Plan's provisions.

GENERAL

The Plan is a defined  contribution  401(k) plan for  employees of  InterDigital
Communications  Corporation and its  participating  subsidiaries (the "Company")
over the age of 18 and who have  completed  one month of  service.  The Plan was
established effective February 1, 1985 and restated January 1, 1997. The Plan is
subject to the  provisions  of the Employee  Retirement  Income  Security Act of
1974, as amended ("ERISA"). Reliance Trust Company is the trustee of the Plan.

CONTRIBUTIONS

All participant  contributions  are made on a before-tax basis. Each participant
may  invest  from 1 percent  to 15  percent  of annual  compensation  as a basic
contribution.  The  total of the  basic and  supplemental  contributions  cannot
exceed IRS limitations for each plan year. For the 2003 and 2002 plan years, the
total IRS limit was $12,000 and $11,000, respectively. If a participant's annual
contributions  exceed the dollar  limitation set by the IRS, thereby requiring a
distribution  of such excess  contributions,  the  participant  will forfeit any
employer  matching  contributions  related to the distribution  amount.  Amounts
forfeited will be used to reduce future employer contributions.

The Company may, at its sole discretion, contribute to the Plan through matching
contributions  and/or  discretionary  contributions.  Beginning  July 2001,  the
Company matches 50 percent of each participant's  contribution,  up to a maximum
of 6 percent of the employees pretax annual basic  compensation,  as defined. 50
percent of the Company  match  consists of cash and the other 50 percent is paid
in the form of the  Company's  Common  Stock.  Discretionary  contributions  are
lump-sum  payments made to the Plan as determined from time to time by the Board
of  Directors  of the  Company.  The  Company  did not  make  any  discretionary
contributions in 2003 and 2002.

The law limits the  amount of pay that may be used to  determine  contributions.
The limit was $200,000 in each of 2003 and 2002.  The law also limits the amount
of all  contributions  that can be made for or by a participant to the Plan in a
given year. The limit is the lesser of 100 percent of pay or $40,000 for each of
2003 and 2002. Employee rollover  contributions from other qualified  retirement
plans are  permitted;  such  contributions  are  subject to the  conditions  and
procedures set forth in the Plan.

PARTICIPANT ACCOUNTS

Each participant's account is credited with that participant's contributions and
allocations of the Company's  matching and discretionary  contributions and Plan
earnings and losses.  Allocations of discretionary  contributions are based on a
participant's  annual  compensation  relative to the total  compensation  of all
other  participants.  The  benefit to which a  participant  is  entitled  is the
benefit that can be provided from the participant's vested account.  Terminating
participants forfeit unvested Company contributions. Forfeitures are used to pay
Plan expenses or reduce employer contributions.

VESTING

Participants  are  immediately  vested in their  salary  deferral  and  rollover
contributions.  Vesting in Company  contributions is based on length of service.
Participants  vest 33-1/3 percent on each of their first three  anniversaries of
employment.


                                       7


PARTICIPANT LOANS

Any  participant who is an active employee may apply for a secured loan provided
the  request  does not exceed the lesser of 50 percent of their  vested  account
balance  or  $50,000.  The  minimum  loan  amount is  $1,000.  Only one loan per
participant  may be made every 365 days and all loans are subject to approval by
the Plan  Administrator.  Loan terms are limited to five years. Upon termination
of employment  the  outstanding  principal and interest  balance is  immediately
payable.  Interest rates are determined by the loan  administrator in accordance
with  prevailing  market rates on similar types of loans,  ranging  between 4.00
percent and 11.00 percent at December 31, 2003. Interest paid by the participant
is credited to the  participant's  account.  If a participant's  balance remains
unpaid for more than 90 days after it is due, the loan will be in default on the
outstanding loan amount and the participant's  vested account will be reduced by
the amount of the unpaid principal and interest. The unpaid amount is treated as
a taxable withdrawal and is subject to federal income taxes.

When a  participant  receives  a  distribution  from the Plan,  any  outstanding
principal  plus  accrued  interest  will be  deducted  from  the  amount  of the
distribution.  A  participant  may  then  either  default  on the  loan  or make
arrangements to continue loan  repayments  beyond when they become entitled to a
distribution  as long as their  remaining  interest  in the Plan  exceeds  their
outstanding loan balance.

PAYMENT OF BENEFITS

If a participant  retires,  dies,  becomes  permanently  disabled,  or otherwise
separates  from the Company,  the  participant or  participant's  beneficiary is
entitled  to the  vested  amount of their  account  as valued on the  applicable
valuation  date. In the event of a  participant's  death,  distribution of their
account will be made as soon as administratively practicable upon the receipt of
appropriate  documentation from their designated beneficiary.  Distributions for
reasons of retirement,  permanent  disability or  termination  will be made upon
written request.  Distributions from a participant's account are typically made,
subject to certain limitations, using a single installment or deferred payment.

PLAN TERMINATION

The Company may amend or suspend the Plan and may terminate the Plan at any time
subject to the  provisions of ERISA;  although  there is no present intent to do
so. However,  no such action may cause the Plan's assets to be used for purposes
other than the exclusive benefit of the participants and their beneficiaries. If
the Plan is  terminated,  all such  participant's  accounts  shall  become fully
vested  and  all  accounts  of  participants  shall  be  distributed  as soon as
administratively possible.

INVESTMENT OPTIONS

All  investments  are  participant  directed  except for 50 percent of the match
contribution,  which by the terms of the Plan, is directed by the Company to the
InterDigital  Stock Fund.  Participants  may change the investment of their Plan
account at any time except for that portion of a participant's Plan account that
is attributable to the Company's matching  contribution(s) made after June 2001.
During the plan years ending December 31, 2003 and 2002,  participants were able
to allocate their  contributions,  in 1 percent increments,  among the following

PLAN AMENDMENTS

In June 2001, the Company's  Compensation & Stock Option Committee authorized an
amendment to the Plan to include increasing the Company's matching  contribution
from 25 percent to 50 percent of the first 6 percent of a  participant's  annual
compensation that a participant  contributes to the Plan, (paying the additional
25 percent  matching  contribution  in the Company's  Common Stock),  adding the
Company's  Common  Stock  to  the  selection  of  investments  under  the  Plan,
permitting an  additional  discretionary  year-end  matching  contribution  and,
effective for employees hired on or after January 1, 2002, extending the vesting
period  of  the  Company's   matching   contributions  to  36  months  from  the
commencement of employment. The prior vesting policy permitted immediate vesting
of 33 percent upon  commencement of employment and vesting of 67 percent and 100
percent on the first and second  anniversaries  of  commencement  of employment,
respectively. Under the current vesting policy, participants vest 33-1/3 percent
on each of their first three anniversaries of employment.

In August 2001,  400,000 shares of the Company's  authorized but unissued Common
Stock were reserved for issuance to the account of  participants  in the Plan as
matching  contributions.  An agreement was entered into between the Company,  on
behalf of the Plan, and Web401(k).com and Fidelity Investments to serve as third
party administrator and custodian, respectively, of the InterDigital Stock Fund.

NOTE 2--SUMMARY OF ACCOUNTING POLICIES

The following  accounting  policies,  which conform with  accounting  principles
generally accepted in the United States of America,  have been used consistently
in the preparation of the Plan's financial statements:

BASIS OF ACCOUNTING

Accounting  records  are  maintained  by the  custodian  on the  cash  basis  of
accounting.   The  financial   statements  of  the  Plan  reflect  all  material
adjustments  to  place  the  financial   statements  on  the  accrual  basis  of
accounting.

USE OF ESTIMATES

The  preparation  of  financial   statements,   in  conformity  with  accounting
principles  generally  accepted  in  the  United  States  of  America,  requires
management to make estimates and assumptions that affect the reported amounts of
assets and  liabilities  and disclosure of contingent  assets and liabilities at
the date of the financial  statements,  as well as reported amounts of additions
and  deductions  during the reporting  period.  Actual results could differ from
those estimates.

INVESTMENT VALUATION AND INCOME RECOGNITION

Investments  in pooled  separate  accounts  are stated at fair value.  Shares of
registered  investment  companies  are  valued at  quoted  market  prices  which
represent  the net  asset  value of  shares  held by the Plan at  year-end.  The
InterDigital  Stock Fund and The Principal  Financial Group,  Inc. Stock Account
are valued at their  year-end  unit  closing  price  (comprised  of common stock
market price plus  uninvested cash  position).  Participant  loans are valued at
cost, which approximates fair value.

Purchases and sales of investments are recorded on a trade-date basis.  Interest
income is accrued when earned.  Dividend  income is recorded on the  ex-dividend
date. Capital gain distributions are included in dividend income.

PAYMENT OF BENEFITS
Benefits are recorded when paid.

FORFEITED ACCOUNTS

At December  31, 2003,  forfeited  non-vested  accounts  totaled  $7,820.  These
forfeited  accounts  were fully  utilized  to reduce  future  employer  matching
contributions with respect to 2003.


                                       11



NOTE 3--INVESTMENT CONTRACT WITH INSURANCE COMPANIES

The Guaranteed  Interest Account (the "Account")  provides a guaranteed interest
rate for a two year and five year  period.  The rate  credited to the Account is
the rate in  effect on the day each  deposit  is  directed  to the  Account.  To
simplify  reporting  to  Plan  participants,  all  rates  credited  during  each
twelve-month period are averaged into a single composite rate.

The  guarantees  made with regard to the Account  are  supported  by the general
account of The Principal  Financial Group,  Inc. The general account is invested
mostly  in  private  placement  bonds,  commercial  mortgages,  and  residential
mortgages.  The Account  promises  contract value for a benefit event,  however,
there is a market  adjustment  when funds are withdrawn prior to their maturity.
Thus, the Account is not considered benefit responsive.

NOTE 4--INVESTMENTS

During  2003 and 2002,  the Plan's  investments,  including  gains and losses on
investments  bought  and sold,  as well as held  during  the  year,  appreciated
(depreciated) in value as follows:

                                      2003          2002

NOTE 6--RELATED PARTY TRANSACTIONS

The  Plan  invests  in  shares  of  the  Company's   Common  Stock  through  the
InterDigital  Stock Fund and in Pooled Separate Account and Guaranteed  Interest
Account  investments with The Principal  Financial Group,  Inc.  Transactions in
such investments qualify as party-in-interest  transactions that are exempt from
the prohibited transaction rules.

NOTE 7--PLAN EXPENSES

All costs and expenses incurred in the administration of the Plan (i.e., trustee
and recordkeeper fees) are currently paid by the Company.


NOTE 8--TAX STATUS

The Internal  Revenue  Service has determined and informed the Company by letter
dated July 8, 2002 that the Plan satisfies the qualification  requirements under
Internal  Revenue Code ("IRC")  Section 401(a) and that the trust  maintained in
connection with the Plan satisfies the  requirements for exemption under Section
501(a) of the IRC.  The Company  believes  the Plan is designed and is currently
being operated in compliance with the applicable requirements of the IRC.

NOTE 9 - SUBSEQUENT EVENT

Effective January 1, 2004, the Plan appointed  Diversified  Investment  Advisors
("Diversified")   to  replace   Principal  as  the  custodian  and  third  party
administrator  for the majority of Plan Assets.  Also effective January 1, 2004,
Diversified  replaced  Web401k  and  Fidelity  Investments  as the  third  party
administrator and custodian,  respectively, of InterDigital Common Stock held by
the Plan.

On December 31, 2003,  Principal converted a portion of the Plan's holdings into
cash in preparation for the transfer of funds to Diversified.  In January, 2004,
Principal   transferred   approximately   $13.9  million  cash  to  Diversified.
Diversified invested these funds into investment options offered by Diversified,
in  accordance  with the  instructions  of each  participant.  In January  2004,
Principal and Fidelity (as  custodians)  also  transferred  InterDigital  Common
Stock with a total fair value of approximately $1.8 million,  as of December 31,
2003, to Diversified.
