either to admit or deny the allegations of paragraph 62, and on that basis deny each and every allegation in paragraph 62. 63. The Kaiser Permanente Defendants admit that some of them operate automated

telephone systems which contain interactive features. Except as expressly admitted, the Kaiser Permanente Defendants deny each and every remaining allegation in paragraph 63.

68-74. The allegations of paragraph 68-74 are not directed at the Kaiser Permanente Defendants and, therefore, no answer is required or made. REQUEST FOR RELIEF The Kaiser Permanente Defendants deny that RAKTL is entitled to any of the relief

AFFIRMATIVE DEFENSES Without admitting or acknowledging that they bear the burden of proof as to any of them, the Kaiser Permanente Defendants, pursuant to Rule 8(c) of the Federal Rules of Civil Procedure, assert the following affirmative defenses: First Affirmative Defense (Non-Infringement) 68. RAKTL is not entitled to any relief against the Kaiser Permanente Defendants

because the Kaiser Permanente Defendants are not infringing, and have not infringed, either literally or under the doctrine of equivalents, directly, by inducement, contributorily, or in any way, any valid, enforceable claim of the `968, `252, `309, `285, `707, `863, `156, `551, `734, `762, `893, `120, `135, `065, `965, `134, `223 and `360 patents (collectively "the RAKTL asserted patents"). Second Affirmative Defense (Patent Invalidity) 69. The RAKTL asserted patents, and all of their claims, are invalid under one or more

sections of Title 35 of the U.S. Code, including, without limitation, 35 U.S.C. §§ 101, 102, 103 and 112.

Third Affirmative Defense (Scope of the Prior Art) The prior art known before the alleged inventions covered by the RAKTL asserted

patents limits and restricts the scope of the RAKTL asserted patents such that the Kaiser Permanente Defendants do not infringe any claims of the RAKTL asserted patents. Fourth Affirmative Defense (Unclean Hands) Each of RAKTL's claims against the Kaiser Permanente Defendants is barred, in

whole or in part, by the doctrine of unclean hands. Fifth Affirmative Defense (Waiver, Laches, or Estoppel) Each of RAKTL's claims against the Kaiser Permanente Defendants is barred, in

whole or in part, by the doctrine of waiver, laches or equitable estoppel due to RAKTL's unreasonable delay in bringing this suit against them. Sixth Affirmative Defense (Prosecution History Estoppel) On the basis of the prosecution history of each of the RAKTL asserted patents and

related patents, RAKTL's claims against the Kaiser Permanente Defendants are barred, in whole or in part, by prosecution history estoppel. Seventh Affirmative Defense (Prosecution Laches) On the basis of the prosecution history of each of the RAKTL asserted patents and

related patents, RAKTL's claims against the Kaiser Permanente Defendants are barred, in whole or in part, by prosecution laches. Eighth Affirmative Defense (Patent Misuse) RAKTL's claims against the Kaiser Permanente Defendants are barred in whole or

in part because RAKTL has engaged in patent misuse.

Ninth Affirmative Defense (Implied License or Patent Exhaustion) RAKTL's claims against the Kaiser Permanente Defendants are barred in whole or

in part by express or implied license and/or by the doctrine of patent exhaustion. Tenth Affirmative Defense (Statute of Limitations) RAKTL's claims against the Kaiser Permanente Defendants are barred by the

statute of limitations set out in 35 U.S.C. § 286 to the extent the Kaiser Permanente Defendants' alleged infringement occurred more than six years prior to RAKTL filing this action. Eleventh Affirmative Defense (Failure to Provide Notice) RAKTL's claims for damages against the Kaiser Permanente Defendants are

barred by 35 U.S.C. § 287(a) for any alleged infringement that occurred prior to RAKTL giving actual notice of the RAKTL asserted patents to the Kaiser Permanente Defendants. Twelfth Affirmative Defense (Unenforceability) The RAKTL asserted patents are unenforceable, in whole or in part, due to the

inequitable conduct by RAKTL, prior assignees of some of the RAKTL asserted patents, by Ronald A. Katz, and/or by their attorneys and appointed representatives (collectively "Katz") before the United States Patent and Trademark Office ("the PTO") during the prosecution of the RAKTL asserted patents and/or related patents and patent applications. 80. Title 37 of the Code of Federal Regulations ("CFR") § 1.56 and the Manual of

Patent Examination Procedure ("MPEP") § 2000.01, et seq. impose a duty of candor and good faith on each individual associated with the filing and prosecution of a patent application before the PTO, which requires that he or she disclose to the PTO all information that is material to the patentability of the application under examination. Breach of this duty of candor, good faith and honesty with intent to deceive the PTO constitutes inequitable conduct so as to render the affected patents unenforceable.

81.

Upon information and belief, Katz, with the intent to deceive the PTO into issuing

patent claims of a scope beyond any to which Katz was entitled, exercised a pattern and practice of conduct as part of the prosecution of the applications that ultimately led to the RAKTL asserted patents and related applications, upon which the RAKTL asserted patents claim priority and which also contain related and material claimed subject matter, that violated the duty of candor and good faith and honesty owed by patent applicants. 82. Upon information and belief, on multiple occasions as part of the prosecution of

the RAKTL asserted patents and in related patents and/or applications, Katz, with an intent to deceive the PTO (i) failed to disclose material prior art known to Katz; (ii) failed to inform the PTO of inconsistent positions taken during prosecution; (iii) failed to identify and disclose material information from related litigation or proceedings; (iv) failed to inform patent examiners of adverse findings by other examiners; (v) made false claims of priority so as to avoid prior art; and (vi) engaged in a pattern of delaying disclosure of known prior art to the PTO and mischaracterizing the relevance of that prior art. Katz's repeated and intentional violations of the duty of candor, good faith and honesty, which are set forth in detail below, render the RAKTL asserted patents unenforceable. 83. The following patents, some of which are RAKTL asserted patents and some of

which are related to the RAKTL asserted patents, are particularly relevant to showing the unenforceability of the RAKTL asserted patents based on Katz's inequitable conduct: U.S. Patent Nos. 4,792,968 ("the `968 patent"), 4,845,739 ("the `739 patent"), 4,930,150 ("the `150 patent"), 5,014,298 ("the `298 patent"), 5,048,075 ("the `075 patent"), 5,073,929 ("the `929 patent"), 5,218,631 ("the `631 patent"), 5,224,153 ("the `153 patent"), 5,359,645 ("the `645 patent"), 5,365,575 ("the `575 patent"), 5,561,707 ("the `707 patent"), 5,793,846 ("the `846 patent"), 5,835,576 ("the `576 patent"), 6,016,344 ("the `344 patent"), 6,151,387 ("the `387 patent") and 6,335,965 ("the `965 patent"). The relevant related applications include U.S. Patent Application Nos. 06/753,299 ("the `299 application"), now abandoned, 07/342,506 ("the `506 application"), now abandoned, and 07/640,337 ("the `337 application"), now abandoned.

84.

All of the RAKTL asserted patents claim closely related subject matter and share a

common genealogy. The inequitable conduct committed by Katz as part of the prosecution of the above-identified patents, the RAKTL asserted patents, and related patents and applications has infected the RAKTL asserted patents, thus rendering them unenforceable due to inequitable conduct. 85. Upon information and belief, as part of the prosecution of the RAKTL asserted

patents and related patents and applications, Katz repeatedly failed to disclose material references known to Katz with an intent to deceive the PTO, as set forth below. The Barger Patent 86. Upon information and belief, Katz had knowledge of and failed to disclose U.S.

Patent No. 4,071,698 to Barger, et al. ("the Barger patent") to the PTO as part of the prosecution of several of the RAKTL asserted patents and related patents and/or applications. 87. The Barger patent was filed with the PTO on January 10, 1977, eight years before

the effective filing date of Katz's first patent, and is prior art to all of the RAKTL asserted patents. 88. The Barger patent is material to the RAKTL asserted patents. It discloses an

automated interactive voice system for marketing merchandise, such as audio recordings. The customer selects and listens to an audio demonstration and may arrange payment by credit card or other means. The system maintains a complete record of all transactions, including the number of requests for demonstrations by each customer, in order to maintain current inventory records and to determine trends. The system can use this transaction history to determine whether a customer is a "free loader" and limits the customer's access to the system accordingly. 89. The system disclosed in the Barger patent is also capable of assigning a caller to an

operator who obtains required information from the customer that is placed in a database. When the customer requests a specific demonstration, the operator enters the appropriate code into the system and plays it for the customer. Upon completion of the demonstration, the customer is returned to a live operator, who will take the order.

90.

Many features relevant to Katz's claims are disclosed in the Barger patent. For

example, the Barger patent teaches storing data entered by a caller in a record, limiting the number of times a caller can access the system, and entering credit card information. Because the Barger patent discloses many of the central features claimed by Katz, it would have been material to the PTO in deciding whether to allow Katz's then-pending claims. 91. As further evidence of its materiality, the Barger patent has been the basis for third

party requests for reexamination of the `707 patent, which shares a similar specification and subject matter with many of the RAKTL asserted patents. In 2006 the PTO rejected all 207 claims of the `707 patent based, in part, on the Barger patent. Specifically, in Reexamination Numbers 90/007,074 and 90/006,978 (combined proceedings) the examiner rejected claims 9, 12, 22-25, 137, 141, 144-46, 150-151, 154, 156, and 167 of the `707 patent under 35 U.S.C. § 102 in light of the Barger patent. 92. Upon information and belief, Katz became aware of the Barger patent and its

materiality at least as early as January 1989. Upon information and belief, on or about December 1988, the European Patent Office sent a search report for one of Katz's corresponding European patent applications to Katz's European patent attorney, Graham Frederic Coles. The search report identified the Barger patent as being "particularly relevant" to Katz's application. 93. Notwithstanding Katz's knowledge of the Barger patent and of its materiality,

Katz failed to disclose this material prior art to the PTO during prosecution of at least the `739, `150, `298, `929, `153, `965, `252, `734 and `863 patents. Katz also failed to disclose the Barger patent to the PTO as part of the substantive prosecution of the `285 patent; instead Katz withheld the Barger patent from the PTO until after a notice of allowance had issued. 94. Upon information and belief, Katz withheld the Barger patent with an intent to

deceive the PTO into issuing patent claims of a scope beyond which Katz was entitled to in at least the `739, `150, `298, `929, `153, `965, `252, `734, `863 and `285 patents, thereby committing inequitable conduct and rendering those patents unenforceable, all of which are RAKTL asserted patents or patents from which the RAKTL asserted patents claim priority, or patents related to the RAKTL asserted patents.

The inequitable conduct committed by Katz with respect to at least the `739, `150,

`298, `929, `153, `965, `252, `734, `863 and `285 patents taints other related patents, which claim priority to, or are related to these patents and which claim related subject matter to which the Barger patent is material, rendering these related patents unenforceable. 96. At least the `893 patent, which is a RAKTL asserted patent, claims priority from

and/or is related to and claims related subject matter to both the `150 and `285 patents to which the Barger patent is material. Accordingly, at least the `893 patent is likewise rendered unenforceable due to inequitable conduct committed by Katz as part of the prosecution of the `150 and `285 patents. 97. At least the `252, `734, `120 and `223 patents, which are RAKTL asserted patents,

claim priority from and claim related subject matter to either or both of the `739 and `929 patents to which the Barger patent is material. Accordingly, at least the `252, `734, `120, and `223 patents are likewise rendered unenforceable due to inequitable conduct committed by Katz as part of the prosecution of the `929 and `739 patents. 98. Likewise, at least the `252, `734, `120, `223, `965, `134, `156, `135, `863, `762,

`551, `065, `360, `309, `707, `285 and `893 patents, which are RAKTL asserted patents, all claim priority from and claim subject matter related to the `739 patent to which the Barger patent is also material. Accordingly, at least the `252, `734, `120, `223, `965, `134, `156, `135, `863, `762, `551, `065, `360, `309, `707, `285 and `893 patents are likewise rendered unenforceable due to inequitable conduct committed by Katz as part of the prosecution of the `739 patent. The DeBruyn Reference 99. Upon information and belief, Katz withheld European Patent Specification No.

0032410 to DeBruyn, which corresponds with Canadian Patent No. 1,162,336 ("the DeBruyn patent") from the PTO during prosecution of many of Katz's earlier patents. 100. The DeBruyn patent was published on July 22, 1981 and disclosed an interactive

voice system for implementing a lottery. The DeBruyn patent was cited in the same European search report that identified the Barger patent. The European search report also identified the

DeBruyn patent as "particularly relevant." Therefore, Katz was aware of the materiality of the DeBruyn patent at least as early as January 1989. 101. The DeBruyn patent discloses many features relevant to Katz's claims, including

receiving the caller's telephone number automatically from the telephone network, prompting the caller with instructions, receiving data entered via touch-tone keypads, storing caller-entered data, processing caller-entered data, and qualifying callers. 102. As further evidence of its materiality, the DeBruyn patent has been the basis for

third party requests for reexamination of the `023, `309 and `707 patents, which share similar specifications and subject matter with many of the RAKTL asserted patents. The PTO has rejected many of the claims of the `023, `309 and `707 patents under 35 U.S.C. §§ 102 and 103 based on the DeBruyn patent alone or in combination with other references. 103. In Reexamination Numbers 90/006,977 and 90/007,058 (combined proceedings)

the PTO rejected claims 1, 2, 8, 10, 21, 22-25, and 26 of the `023 patent under 35 U.S.C. § 102 in light of the DeBruyn patent. The PTO also rejected claims 5, 6, 20, 22, and 23 of the `023 patent under 35 U.S.C. § 103 in light of the DeBruyn patent in combination with other references. 104. In Reexamination Numbers 90/007,092 and 90/006,976 (combined proceedings)

the PTO rejected claims 23, 25-37, 41-43, 46, 50 and 51 of the `309 patent under 35 U.S.C. § 102 in light of the DeBruyn patent. The PTO also rejected claims 1, 7-12, 14, 20, 32, 38-42, and 5258 of the `309 patent under 35 U.S.C. § 103 in light of the DeBruyn patent in combination with other references. 105. In Reexamination Numbers 90/007,074 and 90/006,978 (combined proceedings)

the PTO rejected claims 1, 4, 9, 12, 22-24, 26, 32-34, 69, 84-86, 88-93, 96-102, 106-108, 115, 119-123, 131-132, 135, 137, 141-147, 150-153, 165-166, 183-190, 196-200, 202-203, and 206 of the `707 patent under 35 U.S.C. § 102 in light of the DeBruyn patent.

Upon information and belief, Katz was aware of the materiality, significance and

relevance of the DeBruyn patent and his failure to disclose it to the PTO during prosecution of at least the `739, `252, `150, `075, `298, `929, `153, `285, `734, `965 and `863 patents was intentional. 107. Upon information and belief, Katz withheld the DeBruyn patent from the PTO

with the intent to deceive the PTO into issuing patent claims of a scope beyond which Katz was entitled in at least the `739, `252, `150, `075, `298, `929, `153, `285, `734, `965 and `863 patents, thereby committing inequitable conduct and rendering those patents unenforceable. The `739, `252, `150, `075, `298, `929, `153, `285, `734, `965 and `863 patents are all RAKTL asserted patents, patents from which the RAKTL asserted patents claim priority, or patents related to the RAKTL asserted patents. 108. At least the `252, `734, `120, `223, `965, `134, `156, `135, `863, `762, `551, `065,

`360, `309, `707, `285 and `893 patents, which are RAKTL asserted patents, all claim priority from and claim subject matter related to the `739 patent to which the DeBruyn patent is also material. Accordingly, at least the `252, `734, `120, `223, `965, `134, `156, `135, `863, `762, `551, `065, `360, `309, `707, `285 and `893 patents are likewise rendered unenforceable due to the inequitable conduct committed by Katz as part of the prosecution of the `739 patent. The Yoshizawa Reference 109. As part of the prosecution of at least the `575, `252, `734 and `965 patents, Katz

failed to disclose a prior art article entitled "Voice Response System For Telephone Betting" by Yoshizawa, et al. ("the Yoshizawa article"). The article appeared in the 1977 issue of Hitachi Review magazine. 110. The Yoshizawa article discloses an automatic off-track betting system. The

system includes a voice response unit, a public telephone network and a central processing unit. Incoming calls are answered by the voice response unit prompting the caller to enter an account number and password, and then select one or more pari-mutuel tickets, for example, a wager on a horse to "show." The entered data is then stored in the caller's account file. Each wager is counted against a preset daily wagering limit. The caller is provided with a registration number

referencing the transaction. Ticket payments are made automatically by deducting the cost of the ticket from the caller's bank account. The article specifically mentions that the system could be used for "winning lot number service", or a lottery. 111. Many features relevant to at least the `575, `252, `734 and `965 patents are

disclosed in the Yoshizawa article. For example, Yoshizawa discloses limiting access and use to a telephone-based gambling or lottery system and qualifying callers based on an account number. 112. Upon information and belief, Katz was aware of the materiality of the Yoshizawa

article at least as early as September 2, 1992, well before the issuance of the `575, `252, `734 and `965 patents, when it was cited in response to interrogatories in the First Data Resources, Inc. v. West Interactive Corp., Civil Action No. 91-4471-TJH (C.D. Cal 1991) litigation. 113. Notwithstanding Katz's knowledge of the Yoshizawa article and its materiality to

at least the `575 patent, upon information and belief, Katz failed to disclose the reference to the PTO as part of the prosecution of at least the `575, `252, `734 and `965 patents in violation of Katz's duty of candor. 114. Upon information and belief, Katz withheld the material Yoshizawa article from

the PTO as part of the prosecution of at least the `575, `252, `734 and `965 patents with intent to deceive the PTO into issuing patent claims of a scope beyond which Katz was entitled, thereby committing inequitable conduct and rendering at least the `575, `252, `734 and `965 patents unenforceable. 115. At least the `135 and `156 patents, which are RAKTL asserted patents, directly

claim priority from and claim subject matter related to the `575 patent to which the Yoshizawa article was material. Accordingly, at least the `135 and `156 patents are likewise rendered unenforceable due to the inequitable conduct committed by Katz as part of the prosecution of the `575 patent. 116. At least the `065, `120, `135, `156, `223, `360, `551, `863 and `893 patents are

are rendered unenforceable by inequitable conduct by Katz's failure to disclose the Yoshizawa article. The Florafax Reference 117. Upon information and belief, during prosecution of the `575 and `576 patent, Katz

had knowledge of and failed to disclose a brochure dated January 22, 1986 and circulated by Florafax at or around that time ("the Florafax brochure"). 118. The Florafax brochure is material to at least the `575 and `576 patents. The

Florafax brochure discloses a service for providing a recorded message in association with the delivery of a floral bouquet. After purchasing a bouquet, the sender receives a card from the florist that includes a telephone number and an ID number. Upon calling the number indicated, the sender is prompted to enter the ID number and record a personal message. When the flowers are delivered, a corresponding card instructs the recipient to call a specified telephone number to hear the sender's personal message. The message may only be played twice before it is automatically erased. The Florafax "talking bouquet" system was test marketed at least as early as December 1985, demonstrating public use of the concepts embodied in the brochure. 119. The Florafax brochure and associated service operation disclose many of the

features claimed in at least the `575 and `576 patents. Upon information and belief, Katz was aware of the materiality of the Florafax brochure at least as early as September 2, 1992, over two years before the issuance of the `575 patent and over seven years before the issuance of the `576 patent, when it was cited in response to interrogatories in the First Data Resources, Inc. v. West Interactive Corp., Civil Action No. 91-4471-TJH (C.D. Cal 1991) litigation. 120. Upon information and belief, notwithstanding Katz's knowledge of the Florafax

brochure and its materiality, Katz failed to disclose it as part of the prosecution of at least the `575 and `576 patents in violation of Katz's duty of candor. 121. Upon information and belief, Katz intentionally withheld the Florafax brochure

from the PTO as part of the prosecution of at least the `575 and `576 patents with an intent to deceive the PTO into issuing patent claims of a scope beyond which Katz was entitled, thereby committing inequitable conduct and rendering at least the `575 and `576 patents unenforceable.

122.

At least the `156 and `135 patents, which are RAKTL asserted patents, claim

priority from and claim subject matter related to the `575 patent to which the Florafax brochure was material. Accordingly, at least the `156 and `135 patents are likewise rendered unenforceable due to the inequitable conduct committed by Katz as part of the prosecution of the `575 patent. 123. At least the `135 patent, which is a patent-in-suit, claims priority from and claims

subject matter related to the `576 patent to which the Florafax brochure was material. Accordingly, at least the `135 patent is likewise rendered unenforceable due to the inequitable conduct committed by Katz as part of the prosecution of the `576 patent. The Katz PCT Reference 124. Upon information and belief, Katz failed to disclose the publication of Katz's own

PCT application, WO 87100375 ("the WO `375 application") during the prosecution of the `285, `863, `156 and `551 patents, which are all RAKTL asserted patents. Upon information and belief, Katz also failed to disclose the WO `375 application as part of the prosecution of at least the related `739 and `929 patents. 125. The WO `375 application was published on January 15, 1987. The WO `375

application would therefore be considered prior art for any claims with a filing date more than a year after the publication date under 35 U.S.C. § 102(b). In particular, the WO `375 application constituted prior art to all claims that incorporated any new subject matter added in these applications, including at least the `739, `929, `285, `863, `156 and `551 patents. 126. The published WO `375 application would have been material to a PTO examiner

in determining what claims, if any, Katz might be entitled to in the `285, `863, `156 and `551 RAKTL asserted patents and the related `739 and `929 patents. The WO `375 application would have been relevant to many of the basic elements claimed in the patents­in-suit, such as prompting the caller with instructions, receiving data entered via touch-tone telephone keypads, storing caller-entered data, processing caller-entered data, and qualifying callers. 127. Upon information and belief, despite Katz's duty to disclose material information

to the PTO, and despite Katz's personal knowledge of the WO `375 application and its

materiality, Katz failed to disclose the WO `375 application to the PTO during the examination of at least the `285, `863, `156, `551, `739 and `929 patents. 128. Upon information and belief, Katz intentionally withheld the WO `375 application

from the PTO during the examination of at least the `285, `863, `156, `551, `739 and `929 patents with an intent to deceive the PTO into issuing patent claims of a scope beyond which Katz was entitled, thereby committing inequitable conduct and rendering the `285, `863, `156, `551, `739 and `929 patents unenforceable. 129. The inequitable conduct committed by Katz in connection with the `285, `863,

`156, `551, `739 and `929 patents taints other related patents which claim priority from those patents and which claim related subject matter to which the WO `375 application was material, rendering these related patents unenforceable. For example, all of the Katz asserted patents, with the exception of the `968 patent, claim priority from and claim subject matter related to the `739 patent to which the WO `375 application was material. Accordingly, at least the `252, `734, `120, `223, `965, `134, `156, `135, `863, `762, `551, `065, `360, `309, `707, `285 and `893 patents are likewise rendered unenforceable due to inequitable conduct committed in the parent `739 patent. The Periphonics References 130. Upon information and belief, Katz intentionally withheld from the Patent and

Trademark Office highly relevant and material prior art by the Periphonics Corporation ("Periphonics") in order to obtain claims to which Katz was not entitled. 131. Upon information and belief, in April of 1993, in connection with First Data

Resources, Inc. v. West Interactive Corp., CV 91-4471TJH, U.S. District Court, Central District of California ("the West case"), materials bearing Bates numbers W72807-W73756 ("the West materials") were provided to Harold Wurst, Esq. of Nilsson, Wurst & Green ("the Nilsson firm"). 132. Upon information and belief, the Nilsson firm was involved in prosecuting many

of Mr. Katz's patent applications, including many of those which would later issue as the RAKTL asserted patents. 133. Upon information and belief, included in the West materials were a number of

Periphonics references, including 1) Bank-From-Home Product Description, Publication

#3000002, January 7, 1980 ("the Bank-From-Home reference") (Bates numbers W73055W73095) and 2) Periphonics VoicePac System with Peritalk/Announce Product Description and user Guide, Publication #3270601C, 1987 ("the VoicePac reference") (Bates numbers W73219-W73302). 134. Upon information and belief, both the Bank-From-Home reference and VoicePac

reference are highly relevant and material to many claims of the RAKTL asserted patents. The Bank-From-Home reference describes such limitations of claims of the RAKTL asserted patents as structures for interfacing, storing, qualifying, switching, processing, voice generation, verifying credit and designating, as related to callers to the disclosed system. The VoicePac reference describes such limitations of claims of the RAKTL asserted patents as interfacing callers to the system and transferring callers to a customer service representative. 135. Upon information and belief, during the prosecution of U.S. Patent Application

No. 08/306,456, which ultimately issued as the `965 patent, Katz stated: "During litigation [of the West case], a voluminous quantity of prior art, that is, some 500 items (including single or plural related documents grouped together), were identified by the defendant. However, during pretrial procedures, the defendant distilled the applied art to 59 separate items (including single or plural related documents)." Paper no. 3, filed November 4, 1994. Katz also stated: "The voluminous quantity of art identified during litigation, excluding the 59 items (Set I), is listed on the second set of forms PTO-1449 (Supplemental I)." Paper no. 3, filed November 4, 1994. 136. Upon information and belief, Katz made the same statements in at least those

applications that later issued as the `285 patent and the `707 patent. 137. Upon information and belief, at least the applications for the `863 and `551 patents

refer the examiner to the references disclosed during the prosecution of the `707 patent. 138. Upon information and belief, while other references in the West materials were

submitted to the PTO during prosecution of the `707, `965, `285, `863 and `551 patents, the BankFrom-Home and VoicePac references were withheld despite knowledge of their materiality. 139. Katz's failure to disclose this material prior art was a violation of the duty of

candor owed to the PTO, and constitutes inequitable conduct.

140.

Due to the inequitable conduct that occurred during the prosecution of their

respective applications, at least the `707, `965, `285, `863 and `551 patents are rendered unenforceable. 141. At least the `065 and `360 patents are related to and claim related subject matter to

the `551 patent to which the Bank-From-Home and VoicePac references were material. Accordingly, at least the `065 and `360 patents are likewise rendered unenforceable due to inequitable conduct committed by Katz during the prosecution of the `551 patent. 142. At least the `893 patent is related to and claims related subject matter to the `285

patent to which the Bank-From-Home and VoicePac references were material. Accordingly, at least the `893 patent is likewise rendered unenforceable due to inequitable conduct committed by Katz during the prosecution of the `285 patent. 143. Thus, Katz's inequitable conduct renders each of the `965, `285, `863, `551, `893,

`065, `707 and `360 patents unenforceable. The Corbett Reference 144. Upon information and belief, Katz had knowledge of and failed to disclose a

reference entitled "Telephone Enquiry System Using Synthetic Speech" by Angela J. Corbett ("the Corbett Reference") as part of the prosecution of at least the `965 and `285 RAKTL asserted patents. Upon information and belief, Katz unreasonably delayed disclosing the Corbett Reference to the PTO and mischaracterized its materiality in connection with the prosecution of at least the `734, `120, `134 and `223 patents. 145. Upon information and belief, Katz had knowledge of the Corbett Reference and its

materiality at least as early as August 13, 1993 when it was disclosed in connection with the First Data Resources Inc. v. West Interactive Corp., et al. Litigation, Civil Action No. 91-4471-TJH, in the United States District Court for the Central District of California. Upon information and belief, First Data Resources (which later became known as RAKTL) had knowledge of the Corbett Reference in connection with West Interactive's motion for summary judgment of invalidity of the Katz patents at issue in that case.
