                     INTERDIGITAL COMMUNICATIONS CORPORATION

                                 PROXY STATEMENT
                     FOR THE ANNUAL MEETING OF SHAREHOLDERS
                             TO BE HELD JUNE 4, 2001

         The Board of Directors of InterDigital Communications Corporation, a
Pennsylvania corporation (the "Company"), is furnishing you this proxy statement
to solicit proxies on its behalf to be voted at the Annual Meeting of
Shareholders (the "Meeting"). The Meeting will be held at the Hilton Valley
Forge, King of Prussia, Pennsylvania on June 4, 2001. The proxies may also be
voted at any adjournments or postponements of the Meeting. This Proxy Statement
and the accompanying proxy will be first sent or given to shareholders on
approximately May 4, 2001. The principal executive offices of the Company are
located at 781 Third Avenue, King of Prussia, Pennsylvania 19406-1409.


         Only holders of record of shares of Common Stock at the close of
business on April 27, 2001 are entitled to vote at the Meeting or any
adjournments or postponements of the Meeting. On that date there were 53,292,613
shares of the Company's Common Stock outstanding and entitled to vote. Each
share of Common Stock entitles the holder to one vote, and votes may not be
cumulated in the election of directors. Holders of the Company's $2.50
Cumulative Convertible Preferred Stock are not entitled to vote at the Meeting.
Under Pennsylvania law and the By-Laws of the Company, the presence of a quorum
is required for each matter to be acted upon at the Meeting. The presence, in
person or by proxy, of holders of the Common Stock entitled to cast at least a
majority of the votes which all holders of the Common Stock are entitled to cast
will constitute a quorum for purposes of the Meeting. Directors are elected by a
plurality vote and approval of all other matters presented at the Meeting
requires the affirmative vote of a majority of the votes cast by shareholders
present, in person or by proxy, at the Meeting. Votes withheld and abstentions
will be counted in determining the presence of a quorum, but will not be voted
and will have no effect on matters to be voted upon at the Meeting. Broker
non-votes will not be counted as votes cast on a proposal and will have no
effect on matters to be voted upon.

         A form of proxy is enclosed for use at the Meeting. Proxies will be
voted in accordance with shareholders' instructions. If no instructions are
indicated on the proxy, all shares represented by valid proxies received
pursuant to the solicitation (and not revoked before they are voted) will be
voted FOR the election of the nominees named below as directors, and FOR the
ratification of the appointment of Arthur Andersen LLP as independent public
accountants to examine the financial statements of the Company for the year





                                        1


ending December 31, 2001, and by the proxies in their discretion on any other
matters to come before the Meeting. A proxy may be revoked at any time before it
is voted at the Meeting by delivering another later dated proxy, by sending
written revocation to the Secretary of the Company or by attending the Meeting
and voting in person. To be eligible to vote in person at the Meeting, a
shareholder must be the registered owner of the shares or, if the shares are
held in the name of a broker or bank, bring a legal proxy obtained from such
broker or bank.


         The cost of solicitation of proxies by the Board of Directors of the
Company (the "Board") will be borne by the Company. Proxies may be solicited by
mail, electronic mail, personal interview, telephone or telegraph and, in
addition, directors, officers and regular employees of the Company may solicit
proxies by such methods without additional remuneration. In addition, the
Company has retained W.F. Doring & Co. to aid in the solicitation of proxies for
which a fee of approximately $7,000, plus expenses, will be paid. Banks,
brokerage houses and other institutions, nominees or fiduciaries will be
requested to forward the proxy materials to beneficial owners in order to
solicit authorizations for the execution of proxies. The Company will, upon
request, reimburse such banks, brokerage houses and other institutions, nominees
and fiduciaries for their expenses in forwarding such proxy materials to the
beneficial owners of the Company's Common Stock.

                              ELECTION OF DIRECTORS
                                  (Proposal 1)


         The Board presently consists of six members, divided into three classes
each having a term of three years. The Board has nominated two current directors
for election at the Meeting for a term expiring at the year 2004 Annual Meeting
of Shareholders and until their successors are elected and qualified. Unless
authority to vote for the nominees is withheld in the proxy, the persons named
in the accompanying proxy intend to vote the shares represented by the proxy FOR
the election as director of the nominees named below. We have no reason to
believe that the named nominees will be unavailable to serve if elected.
However, if either of the nominees is unavailable to serve for any reason, the
proxies may be voted for another person nominated as a substitute by the Board.
Four incumbent directors will continue to serve as directors following the
Meeting as set forth below, with two directors having a term expiring at the
year 2002 Annual Meeting of Shareholders and two directors having a term
expiring at the year 2003 Annual Meeting of Shareholders.

and Incentive Plan. These options are granted automatically in an amount equal
to 10,000 multiplied by the number of years remaining in the Director's term in
office at an exercise price equal to the fair market value of the Common Stock
on the date of grant. The options vest annually on the date of each year's
Annual Meeting of Shareholders at the rate of 10,000 shares per year commencing
on the date of the Annual Meeting following the Annual Meeting of Shareholders

         In connection with his service and extra commitment of time as Chairman
of the Board during 2000, Mr. Campagna was awarded 40,000 restricted stock units
under the Company's 1999 Restricted Stock Plan (RSUs) in 2000 and 100,000 RSUs
in 2001. In connection with his service on the Board during 2000, Mr. Roath was
awarded 10,000 options to purchase Common Stock in 2000 under the Company's 1997
Stock Option Plan for Outside Directors and 20,000 RSUs in 2001. During 2000
each of the Outside Directors was awarded RSUs in exchange for the
relinquishment of a tax gross-up feature associated with previously granted
restricted stock. The number of such RSUs were as follows: Mr. Campagna, 40,000;
Mr. Colson, 12,000; Mr. Clontz, 12,000; and Mr. Roath, 12,000. The RSUs do not
carry voting rights and, if unvested, they are forfeitable by the grantee upon
his departure from service with the Company. As part of a program to increase
ownership of Common Stock by Board members, the following Outside Directors were
granted four (4) fully-vested options to purchase shares of Common Stock for
each share of stock such directors purchased on the open market from December
21, 2000 to January 10, 2001 as follows: Mr. Campagna, 20,000 options; Mr.
Colson, 52,800 options; Mr. Clontz, 48,000 options; and Mr. Roath, 76,190
options. The aggregate purchase price of shares eligible for the option match
was capped at $100,000 for Outside Directors. In addition, Mr. Colson was
granted 20,000 options under the Company's 2000 Stock Award and Incentive Plan
and 5,000 shares of stock under the Company's 1999 Restricted Stock Plan. The
exercise price of all these options was the fair market value of the Common
Stock on the date of grant.


                          Compliance with Section 16(a)
                     of the Securities Exchange Act of 1934

         Section 16(a) of the Securities Exchange Act of 1934 (the "Exchange
Act") requires the Company's directors and executive officers, and persons who
own more than ten percent of a registered class of the Company's equity
securities, to file with the Securities and Exchange Commission, initial reports
of ownership and reports of changes in ownership of Common Stock and other
equity securities of the Company. Executive officers, directors and greater than
ten percent shareholders (collectively, "Reporting Persons") are additionally
required to furnish the Company with copies of all Section 16(a) forms they
file.

         To the Company's knowledge, based solely on review of the copies of
such reports furnished to the Company and written representations of Reporting
Persons that no other reports were required with respect to fiscal 2000, the
Reporting Persons complied with Section 16(a) filing requirements, with the
exception of one late report filed by Mark Gercenstein.

                             Executive Compensation

             Compensation Committee Report on Executive Compensation

General

The Company's Compensation and Stock Option Committee (the "Committee") has
overall responsibility for the establishment, modification and implementation of
executive compensation and benefit programs of the Company. The Committee's
primary responsibilities include: adopting compensation plans, setting annual
salary, bonus and other direct or indirect benefits of executive officers and
other members of management, and administering Company stock option, restricted
stock and bonus plans including the grant of awards under such plans to all
eligible employees.

Compensation Philosophy

One of the most important duties of the Committee is to determine the
compensation of the Company's executive officers with the goal of ensuring that
shareholder value serves as a primary driver and motivator of executives.
Accordingly, the Committee's philosophy is to ensure that the Company's
executive compensation is shareholder focused, appropriate and competitive.

In determining the amount and composition of executive compensation for the
Named Officers, as defined below, and the Company's Chief Executive Officer, and
in compliance with its independent oversight responsibilities, the Committee is
guided by the following objectives: to assist the Company to attract and retain
qualified executives in a highly competitive industry; to reward executives
consistent with the Company's performance; to recognize individual performance
and responsibility; to strengthen the mutuality of interest between executives




                                        7


and the Company's shareholders; and to drive long-term performance. The
principal elements of executive compensation are: base salaries, annual
incentive compensation and long-term stock-based compensation. Executive
benefits and perquisites have not historically been a significant component of
the Company's executive compensation, although as part of its overall strategy
the Committee is focused on providing competitive benefits to meet the health,
welfare and retirement needs of all employees.

The Company had two Chief Executive Officers during 2000. When Mr. Goldberg was
promoted to Chief Executive Officer, the Committee determined that offering him
a compensation package substantially similar to that given his predecessor best
served the general compensation objectives outlined above - retention,
recognition of performance, strengthening the mutuality of interest of the Chief
Executive Officer with shareholders and driving long-term performance.

Base Salary

The Company's policy is to set base salaries for each executive officer and the
Chief Executive Officer in the upper middle range of scales for equivalent jobs
with other similarly situated industrial employers. Annual base salaries are
reviewed from time to time with the assistance of outside compensation
consultants and available marketplace competitive data.

Annual Performance-Based Compensation

The Committee has instituted a bonus plan which provides for the payment of
annual incentives to employees, including the Named Officers and the Chief
Executive Officer, based on two factors: the Company's results measured against
its pre-set business goals and individual performance ratings. Each executive
officer was assigned a target percentage of salary (targets at 57% of salary in
the case of the Chief Executive Officer and 40% of salary in the case of the
other Named Officers.) Under the plan up to 30% of the executive's bonus may be
paid in shares of Common Stock which is not transferable for a period of two
years. Achievement of all goals results in payment of the target bonus. If
actual results vary from the goals set, the bonus paid will be adjusted up or
down based on a pre-set formula to reflect the variation from goals. The
adoption of this plan was part of an overall strategy to create an environment
of collective effort towards common goals, to give employees a stake in the
performance of the Company and to appropriately reward employees when Company
performance meets its desired objectives.

To promote these ends, the corporate business goals were set at aggressive
levels in 2000 to incent and compensate superior performance. The Company's




                                        8


actual performance in 2000 with respect to meeting certain of the pre-set
business goals resulted in each of the executive officers and the Chief
Executive Officer, Mr. Goldberg, receiving less than the full amount of their
respective target bonuses. In keeping with the Committee's philosophy to give
executives more of a stake in the performance of the Company, while adding an
equity retention feature, the full 30% of each executive's awards were made in
the form of Common Stock. These shares are restricted as to transferability,
generally for a two-year period, but are not forfeitable (except in the event
that employment is terminated during such two-year period due to intentional
wrong doing). The shares have full voting power and the right to receive
dividends. The Committee also provided additional cash compensation in the form
of a tax gross-up to cover each executives' tax liability associated with the
stock payout.

The amount of Mr. Gercenstein's bonus was negotiated in connection with his
termination of employment and did not include a grant of restricted stock.

During 2000, the Committee engaged Pearl Meyer & Partners, Inc. to selectively
provide recommendations for modifying the Company's performance-based
compensation program to ensure the Company could attract, motivate and retain
appropriate personnel to key positions in the Company while ensuring that the
compensation method would drive shareholder value.

Equity Incentives

Stock options, restricted stock, restricted stock units and shares of Common
Stock having restrictions on transferability have been utilized as long-term
incentives. These instruments function both as effective retention mechanisms
over the medium-term and as methods of focusing executives on shareholder value
in that the value of such forms of equity compensation is either derived from
increases in the Company's stock value or is at-risk based on the value of the
Company's stock.

Restricted stock and restricted stock units issued by the Company generally vest
three years from the original grant date and are forfeited if the recipient
leaves the Company during that period. In 2000, the executive officers and the
Chief Executive Officer were granted RSUs in a number equal to the number of
shares of restricted stock previously granted to them in exchange for the
relinquishment of a tax gross-up feature associated with such shares.

As discussed above, the Committee used Common Stock as a component of executive
bonus compensation for 2000. The use of stock, which is restricted from transfer
for two years, serves to further align executive interests with those of the
shareholders and encourage retention. The Committee may elect, from time to




                                        9


time, to grant restricted stock, restricted stock units or Common Stock to
executives under the 2000 Stock Award and Incentive Plan and the 1999 Restricted
Stock Plan.

In 2000, the Committee also adopted a program of annually evaluating and, if
appropriate, granting stock options on a company-wide basis to further align the
financial interests of all employees with the financial interest of the
shareholders. Options are granted at 100% of the fair market value at the date
of grant. The options granted to the Named Executives in 2000 vested in two
equal installments, one at the close of 2000 and the second to vest in June of
2001. Both persons who served as Chief Executive Officer in 2000 received an
option grant upon his appointment to the position.

As part of its philosophy that increased ownership of equity in the Company
facilitates greater alignment of executive interests with shareholder interests,
the Committee, in consultation with outside compensation advisors, instituted a
special short-term program to incentivize executives to purchase the Company's
Common Stock on the open market. For a period of approximately three (3) weeks,
executives (including the Chief Executive Officer) were granted four fully
vested options for each share of Common Stock they purchased. The 4-for-1
matching grant was capped at the point that the aggregate purchase price of
shares bought by an executive reached the executive's then current salary.


Perquisites

Selective perquisites were given to the Chief Executive Officer in 2000. Mr.
Gercenstein was paid allowances for temporary housing expenses and for a car.
Mr. Goldberg, as Chief Executive Officer, has the same car allowance.

In implementing compensation policies, plans, and programs, the Committee will
consider the effects of Section 162(m) of the Internal Revenue Code. Section
162(m) generally disallows a public company's tax deduction for compensation to
its Chief Executive Officer and four other most highly compensated executive
officers in excess of $1 million in any tax year. Under Section 162(m),
compensation that qualifies as "performance-based compensation" is excluded from
the $1 million deductibility cap, and therefore remains fully deductible even
though such compensation may (together with other compensation) exceed $1
million in a given year. The Committee intends to seek to preserve the tax
deductibility of compensation to executive officers, to the extent that this
objective does not impair the operation and effectiveness of the Company's
compensation policies and programs. To this end, the 2000 Stock Award and
Incentive Plan is being submitted to shareholders in order that annual incentive
awards, stock options and certain other awards under the plan can qualify as
"performance-based compensation" that will remain fully deductible by the
Company. The Committee retains the flexibility, however, to enter into
arrangements that may result in non-deductible compensation to executive
officers.

  Officer (7)



(1)    Amounts listed as bonuses in each fiscal year were accrued but not paid
       until the following year for each Named Officer. With the exception of
       Mr. Gercenstein, thirty percent of the bonuses accrued for 2000 were paid
       in shares of Common Stock which may not be transferred for a period of
       two years. 1999 bonus amounts have been adjusted to conform to the 2000
       presentation.




                                       11


(2)    As permitted by rules established by the Commission, no amounts are shown
       with respect to certain "perquisites" where such amounts do not exceed
       the lesser of 10% of bonus plus salary or $50,000. Mr. Gercenstein's
       other annual compensation was comprised of allowances for a car ($11,926)
       and housing ($19,860).

(3)    At December 31, 2000, each of the following Named Officers owned the
       following number of RSVs with the following values: Mr. Goldberg, 20,000
       units, $108,700; Mr. Lemmo, 17,500 units, $94,675; Mr. Tilden, 15,833
       units, $85,657; Mr. Merritt, 15,000 units, $81,150; Mr. Fagan, 15,000
       units, $81,150; Mr. Gercenstein, 5,000; $27,050. The grantees of the
       RSVs have the right to receive dividend equivalents to the extent
       dividends are paid on the Common Stock. Dividends have never been paid on
       the Company's Common Stock nor does the Board have any current intention
       to pay dividends.

(4)    Amounts listed under "All Other Compensation" for 2000 represent the
       dollar value of insurance premiums with respect to term life insurance
       (Mr. Goldberg $719; Mr. Lemmo $313; Mr. Tilden $443; Mr. Merritt $278;
       Mr. Fagan $278) and 401(k) matching (Mr. Goldberg $2,400; Mr. Lemmo
       $2,625; Mr. Tilden $2,523; Mr. Merritt $2,253; Mr. Fagan $2,399; Mr.
       Gercenstein $875); except that the amount listed for Mr. Gercenstein also
       represents a salary continuation payment of $39,774, a vacation pay-out
       of $22,270 and a $100,000 signing bonus.

(5)    Mr. Goldberg served as Interim President of the Company from September
       1999 until November 2000 when he was named Chief Executive Officer. He
       became President in January 2001.

(6)    Mr. Fagan joined the Company as Chief Financial Officer in November 1998.

(7)    Mr. Gercenstein joined the Company as Chief Executive Officer in April
       2000; he left the Company in November 2000. Upon his departure all 25,000
       unvested RSUs granted to him terminated and 125,000 unvested stock
       options terminated.


         Each of the current Named Officers has entered into an employment
agreement with the Company (the "Employment Agreements") that provides severance
pay benefits, among other things, in certain events of termination of
employment. The Employment Agreements (except in the case of the Chief Executive
Officer) generally provide that the Company may enforce up to a one year
covenant not to compete by paying severance of up to one year's salary and one
year's continuation of medical and dental benefits during which time the
individual is subject to non-compete provisions. Such agreements also provide a
one-year covenant-not-to-compete without payment of severance following
termination by the Company for "cause", as defined in the Employment Agreements.
In addition, in the event of a termination within one year after a change of
control, which is defined as the acquisition, including by merger or
consolidation, or by the issuance by the Company of its securities, by one or
more persons in one transaction or a series of related transactions, of more
than fifty percent of the voting power represented by the outstanding stock of
the Company or a sale of substantially all the assets of the Company, the




                                       12


employee would generally receive two years salary, all of his target bonus
(except in the case of the Chief Executive Officer) and the immediate vesting of
all stock options and restricted stock. The Agreements also provide that if any
amount payable to the officers is subject to a federal exise tax imposed on
"excess parachute payments", the officer shall be entitled to a cash payment
sufficient to indemnify him for such tax.

         Under the terms of his Employment Agreement, Mr. Goldberg's service as
director of the company is conditioned upon his retention as Chief Executive
Officer. Mr. Goldberg's agreement also provides for a one-year
covenant-not-to-compete regardless of the reason for termination and independent
of any obligation the Company may have to pay severance.

         In connection with his departure from the Company in November 2000, Mr.
Gercenstein executed a separation and confidentiality agreement. The agreement
provides, in part, for salary continuation ($350,000 per annum) for eighteen
months, a bonus payment which was paid in December 2000 and the continuation of
medical and dental benefits which ceased when he became eligible to participate
in a new employer's plan. Under the terms of Mr. Gercenstein's Employment
Agreement, Mr. Gercenstein is subject to a one-year covenant-not-to-compete
regardless of the reason for termination and independent of any obligation the
Company may have to pay severence.

         The Employment Agreements (originally executed between October 1996 and
November 1998) provide for the payment of annual salaries to said Executive
Officers which may be increased from time to time. Current salaries paid
pursuant to the Employment Agreements are: Mr. Goldberg, $350,000; Mr. Lemmo, $
233,730; Mr. Merritt, $200,340; Mr. Fagan, $200,340; and Mr. Tilden, $211,470.

(1)      Potential Realizable Value is reported net of the option exercise
         price, but before taxes associated with the exercise. These amounts
         represent certain assumed rates of appreciation only and are not
         necessarily reflective of gains actually achievable. Actual gains, if
         any, on stock option exercises are dependent upon the future
         performance of the Company's Common Stock.

(2)      All unvested options (125,000) terminated on the date Mr. Gercenstein
         left the Company. On February 20, 2001, 3,846 of his incentive stock
         options expired. On May 20, 2001, the remaining 21,154 non-qualified
         stock options will expire.

communication between the Board and the Company's independent public
accountants.
