`
`The ‘095 Patent issued May 22, 2001 from Application No. 09/003,541
`
`(“‘541 Appln.”), which was filed Jan. 6, 1998. The ‘541 Appln. is a divisional
`
`application of the 08/595,014 Application, filed Jan. 31, 1996, which claims
`
`priority to Provisional Application No. 60/004,510, filed Sep. 29, 1995.
`
`Accordingly, the earliest possible date to which the ‘095 Patent could claim
`
`priority (hereinafter the “earliest effective filing date”) is September 29, 1995.
`
`Further, Petitioner does not concede that the ‘095 Patent is entitled to this
`
`priority date, but has elected not to argue the issue in the Petition because all prior
`
`art references identified in the Grounds presented below pre-date the earliest
`
`possible priority date for the ‘095 Patent. However, Petitioner explicitly reserves the
`
`right to present such an argument in this proceeding or other proceedings involving
`
`the ‘095 Patent.
`
`Hawkes was published in 1990 by BSP Professional Books. Ex. 1003. The
`
`Ishiguro patent application was published on March 23, 1994. Ex. 1004. The
`
`Bannon, Priven, Dreifus, and Halpern patents were each issued/published by the
`
`35414971.1
`
`
`
`-5-
`
`
`
`
`
`United States Patent and Trademark Office more than one year before the earliest
`
`priority date of the ‘095 Patent. Ex. 1005 – Ex. 1009. Therefore, the Hawkes,
`
`Ishiguro, Bannon, Priven, Dreifus, and Halpern references of Grounds 1-7 are
`
`available as prior art under 35 U.S.C. §102(b). Davis was filed on June 9, 1994,
`
`which is more than one year before the earliest effective filing date of the ‘095
`
`Patent. Therefore, the Davis reference of Grounds 1-3 and 7 is available as prior art
`
`under 35 U.S.C. § 102(e).
`
`IV. REASONS FOR THE RELIEF REQUESTED UNDER 37 C.F.R. §§
`42.22(A)(2) AND 42.104(B)(4)
`
`A. Background
`
`
`1.
`
`The ‘095 Patent
`
`The ‘095 Patent is directed to an electronic module capable of exchanging
`
`encrypted information with a service provider’s equipment to facilitate secure
`
`transactions. Ex. 1001, Abstract. The electronic module may be incorporated into
`
`an articulatable item, such as a credit card, a ring, a watch, a wallet, a purse, a
`
`necklace, jewelry, an ID badge, a pen, a clipboard, a token, etc. Ex. 1001, 32:15-20.
`
`As illustrated in FIG. 1 of the ‘095 Patent, reproduced below, the electronic module
`
`includes a microprocessor, a clock, a math coprocessor, memory circuitry, an
`
`input/output circuit, and an energy circuit. Ex. 1001, 2:34-67, 3:1-9.
`
`35414971.1
`
`
`
`-6-
`
`
`
`
`
`
`
`The math coprocessor is designed to perform known mathematics operations
`
`for RSA encryption and decryption (e.g., public/private key encryption/decryption)
`
`that would not otherwise be handled by the microprocessor. Ex. 1001, 2:34-67, 3:1-
`
`9. The memory circuity may include read-only-memory and non-volatile random-
`
`access-memory. Ex. 1001, 2:34-67, 3:1-9. The input/output circuit enables
`
`bidirectional communication between the electronic module and an external device,
`
`and may include a one-wire interface. Ex. 1001, 2:34-67, 3:1-9. The energy circuit
`
`may consist of a battery, capacitor, R/C circuit, photovoltaic cell, or any other
`
`equivalent energy producing circuit or means. Ex. 1001, 2:34-67, 3:1-9.
`
`In the described mode of operation representative of the operations of the
`
`claims at issue, the ‘095 Patent discloses that the electronic module is programmed
`
`by a service provider to operate as digital cash dispenser or a cash reservoir that
`
`35414971.1
`
`
`
`-7-
`
`
`
`
`
`allows the end user to make payments for goods and services using the electronic
`
`module. Ex. 1001, 7:66-8:8. The electronic module initially contains a locked
`
`money object containing a given cash value. Ex. 1001, 8:9-19. The electronic
`
`module generates certificates on demand, where the certificates are signed
`
`documents attesting to the fact that the amount of money requested (e.g., for a
`
`purchase) was subtracted from the value of the money object. Ex. 1001, 8:9-19.
`
`The memory of the electronic module stores a transaction count object, a private
`
`key, and other information. Ex. 1001, 9:13-67.
`
`After the electronic module has been programmed by the service provider, the
`
`electronic module may be provided to an end user, who uses the electronic module
`
`to make purchases. Ex. 1001, 9:13-67. To prevent “replays” (i.e., duplication) of
`
`transactions, a challenge/response mode is used whereby a payee (e.g., a merchant)
`
`generates a random challenge number and provides it to the electronic module. Ex.
`
`1001, 8: 20-29. In addition to the challenge number, the payee also provides the
`
`amount of a purchase to the electronic module. Ex. 1001, 9:41-49. The electronic
`
`module, upon receiving the challenge number and the amount of the purchase,
`
`subtracts the amount of the purchase from the money object, and generates a signed
`
`certificate (e.g., using the private key stored in the memory) that includes the
`
`challenge number, the value of the transaction counter object, and the purchase
`
`amount. Ex. 1001, 8:35-43, 9:36-67. The payee, upon receiving the certificate from
`
`35414971.1
`
`
`
`-8-
`
`
`
`
`
`the electronic module, verifies the challenge number and the purchase amount match
`
`the challenge number and purchase amount sent to the electronic module, and, upon
`
`determining a match, delivers the purchased goods to the payer. Ex. 1001, 9:58-62.
`
`The payee provides the certificate received from the electronic module to the
`
`payee’s bank to receive payment in the amount of the purchase from the payee’s
`
`bank. Ex. 1001, 9:63-10:16.
`
`B. Relevant Prosecution History
`
`The ‘095 Patent was filed on January 6, 1998 and assigned U.S. Patent
`
`Application No. 09/003,541 (hereinafter “the ‘541 Application”). The ‘541
`
`Application, as originally filed, included 28 claims. Claims 1-15 were canceled in a
`
`preliminary amendment. Ex. 1010 January 6, 1999 Preliminary Amendment at 1.
`
`Claim 1 of the ‘095 Patent resulted from the prosecution of claim 21 of the ‘541
`
`Application. Further, claims 2-6 of the ‘095 Patent correspond to originally filed
`
`claims 23-27.
`
`Claim 21, as originally filed, recited:
`
`An apparatus for receiving and transmitting encrypted
`data, comprising:
`an input/output interface;
`a microprocessor circuit connected to said input/output interface;
`a coprocessor circuit, connected to said microprocessor circuit,
`for performing encryption and decryption algorithms, said
`apparatus being adapted to encrypt a data packet using a
`key and to transmit said encrypted data packet out of said
`input/output interface.
`
`35414971.1
`
`
`
`-9-
`
`
`
`
`
`A first Office Action was mailed on June 18, 1998, which rejected the claims
`
`under 35 U.S.C. § 102 and 35 U.S.C. § 103. Ex. 1010 June 18, 1999 Office Action.
`
`In the response filed on October 18, 1999, claims 17 and 22 were canceled, new
`
`claims 29-33 were added, of which claims 29 and 30 correspond to claims 7 and 8 of
`
`the ‘095 Patent, and claim 21 was amended as follows:
`
`An apparatus for receiving and transmitting encrypted
`data, comprising:
`an input/output interface for receiving a challenge number from
`an electronic device;
`a microprocessor circuit connected to said input/output interface;
`a coprocessor circuit, connected to said microprocessor circuit,
`for performing encryption and decryption algorithms, said
`apparatus being adapted to encrypt a data packet using a
`key and to transmit said encrypted data packet out of said
`input/output interface;
`a first memory connected to said microprocessor circuit, said
`first memory for storing a first data object; and
`a second memory connected to said microprocessor circuit, said
`second memory including instructions readable by said
`microprocessor
`circuit
`to
`thereby
`cause
`said
`microprocessor circuit to:
`initiate generation of a certificate, said certificate
`including said challenge number and a second data
`object; and
`adjust said first data object according to said second data
`object responsive to a verification signal from said
`electronic device.
`
`Ex. 1010 October 18, 1999 Response at 2 and 3. Thus, claim 21 was broadened to
`
`no longer require that the coprocessor circuit performs encryption and decryption
`
`algorithms, and to no longer require that the coprocessor circuit be adapted to
`
`encrypt a data packet and transmit the encrypted data packet via the input/output
`-10-
`
`35414971.1
`
`
`
`
`
`interface. A second Office Action was mailed on January 4, 2000 where claims 21,
`
`23, and 26-30 continued to be rejected under 35 U.S.C. § 102. Ex. 1010 January 4,
`
`2000 Office Action. In response to the second Office Action, a response after final
`
`was filed, and, in the response, claims 16, 18-20, 28, and 31-33 were canceled, and
`
`claim 21 was amended as follows:
`
`An apparatus for receiving and transmitting encrypted
`data, comprising:
`an input/output interface for receiving a challenge number from
`an electronic device;
`a microprocessor circuit connected to said input/output interface;
`a coprocessor circuit, connected to said microprocessor circuit;
`a timing circuit connected to the microprocessor, the timing
`circuit for generating a time stamp;
`a first memory connected to said microprocessor circuit, said
`first memory for storing a first data object; and
`a second memory connected to said microprocessor circuit, said
`second memory including instructions readable by said
`microprocessor
`circuit
`to
`thereby
`cause
`said
`microprocessor circuit to:
`initiate generation of a certificate, said certificate
`including said challenge number and a second data
`object; and
`adjust said first data object according to said second data
`object responsive to a verification signal from said
`electronic device;[[.]]
`store a transaction script, the transaction script including at
`least a representation of the time stamp generated
`by the timing circuit.
`
`Ex. 1010 April 4, 2000 Response. In the response filed on April 4, 2000, Applicant
`
`argued that the cited art did not disclose the timing circuit as in amended claim 21.
`
`An Advisory Action was mailed on April 11, 2000, and indicated that the limitation
`
`35414971.1
`
`
`
`-11-
`
`
`
`
`
`of “store a transaction script, the transaction script including at least a representation
`
`of the time stamp generated by the timing circuit” raised a new issue requiring
`
`further search and consideration. Ex. 1010 April 11, 2000 Advisory Action. An
`
`RCE requesting entry of the previously filed amendment was filed on May 4, 2000,
`
`and a Notice of Allowance was mailed on July 17, 2000. Ex. 1010 May 4 2000
`
`Response, and July 17, 2000 Notice of Allowance. In the Notice of Allowance, the
`
`Examiner indicated that the ‘541 Application had been allowed because the prior art
`
`does not consider the possibility of “creating within the session key a transaction
`
`script that includes a time stamp generated by a timing circuit for each transaction.”
`
`Ex. 1010 July 17, 2000 Notice of Allowance mailed at 2. The ‘541 Application was
`
`issued on May 22, 2001 as U.S. Patent No. 6,237,095. Ex. 1001. Patent Owner has
`
`disclaimed claim 7 of the ‘095 Patent. CBM 2015-00102, Ex. 2003.
`
`Nowhere in the prosecution history of the ‘541 Application did the Examiner
`
`appear to be aware of using a timing circuit to generate time stamps that are applied
`
`to messages and/or records of transactions. However, generating time stamps using
`
`a timing circuit and applying the time stamps to messages and/or records of
`
`transactions stored was well known to a person of ordinary skill in the art at the time
`
`the ‘541 Application was filed. Ex. 1002 at 43. As an example, Hawkes, which was
`
`published in 1990, teaches that it is necessary to include time stamps in transaction
`
`messages to avoid “replays” of transactions, and further discloses that time stamps
`
`35414971.1
`
`
`
`-12-
`
`
`
`
`
`were used in call detail records to indicate the duration and time of the call(s). Ex.
`
`1003, pages 70, 85, and 86.
`
`C. Claim Construction (37 C.F.R. § 42.104(b)(3))
`
`In an inter partes review, a claim in an unexpired patent is given the “broadest
`
`reasonable construction in light of the specification of the patent in which it
`
`appears.” 37 C.F.R. § 42.100(b). Alternatively, a claim term in an expired patent is
`
`construed according to its ordinary and customary meaning, as understood by one of
`
`ordinary skill in the art. See Ex. 1009 Paper 12 at 3 and 4, and Paper 17 at 2 and 3.
`
`Petitioner notes that the 20 year patent term for the ‘095 Patent will expire prior to a
`
`final written decision in this proceeding. Below, Petitioner provides constructions
`
`for certain claim terms in accordance 37 C.F.R. § 42.104(b)(3). Petitioner
`
`respectfully submits that the constructions provided below would be the same under
`
`both the broadest reasonable interpretation standard, which is used to construe claim
`
`terms in an unexpired patent, and the ordinary and customary meaning standard,
`
`which is used to construe claim terms in an expired patent. The following
`
`summarizes how certain claim phrases of the ‘095 Patent should be construed for
`
`purposes of this Inter Partes Review:
`
`1.
`
`“coprocessor”: The claim term “coprocessor” should be construed as
`
`a processor that works with another processor. Ex. 1002 at 30.
`
`2.
`
`“transaction counter”: A transaction counter is a data object that
`
`35414971.1
`
`
`
`-13-
`
`
`
`
`
`stores a count representative of a number of transactions, and that is stored in a
`
`memory. Ex. 1002 at 31.
`
`3.
`
`“timing circuit”: The claim term “timing circuit” should be construed
`
`as continuously running clock circuitry that tracks time. Ex. 1002 at 32.
`
`4.
`
`“memory means for storing a predetermined program, said
`
`memory means being connected to said microprocessor”: The ‘095 Patent
`
`states:
`
`The memory circuitry 20 may contain both read-only memory and non-
`volatile random-access-memory. Furthermore, one of ordinary skill in
`the art would understand that volatile memory, EPROM, SRAM and a
`variety of other types of memory circuitry could be used to create an
`equivalent device.
`
` ‘095 Patent, 2:34-59. Therefore, the claim term “memory means for storing a
`
`predetermined program,
`
`said memory means being connected
`
`to
`
`said
`
`microprocessor” should be construed to construed to be a memory that is connected
`
`to a processor and that stores a program. Ex. 1002 at 33.
`
`D.
`
`Summary of the Prior Art
`
`
`
` Hawkes 1.
`
`Hawkes describes various design aspects of integrated circuit (IC) cards, tags,
`
`and tokens, and describes various applications for which such devices may be used.
`
`Ex. 1003, Preface, pages ix-xi, pages 1-11, Table 1.4. For example, Hawkes teaches
`
`that the tokens or smart cards may be operated as an electronic wallet capable of
`
`35414971.1
`
`
`
`-14-
`
`
`
`
`
`storing and dispensing data transferred value (e.g., electronic money) in connection
`
`with the purchase of goods or services. Ex. 1003, Preface, page x, pages 7, 36, 37,
`
`65, 69-70.
`
`An exemplary configuration of a token is shown in FIG. 6.3, reproduced
`
`below.
`
`
`
`The token of FIG. 6.3 includes input/output interface (e.g., serial I/O); a
`
`microprocessor circuit (e.g., control processor) connected to the input/output
`
`interface; a coprocessor circuit (e.g., RSA processor) connected
`
`to
`
`the
`
`microprocessor circuit; a timing circuit (e.g., clock) connected to the microprocessor
`
`circuit; a first memory (e.g., data memory shown) connected to the microprocessor
`
`circuit; and a second memory (e.g., program memory) connected to the
`
`microprocessor circuit. See Ex. 1002 at 36-45.
`-15-
`
`35414971.1
`
`
`
`
`
`
`
`A side-by-side comparison of the token illustrated in FIG. 6.3 of Hawkes
`
`(left) and the electronic module illustrated in FIG. 1 of the ‘095 Patent (right) is
`
`shown below.
`
`As can be seen in the side-by-side comparison above, the token of Hawkes contains
`
`the same basic hardware elements (e.g. processor, math coprocessor, memory, clock,
`
`I/O circuitry) as the electronic module disclosed in the ‘095 Patent. See Ex. 1002 at
`
`
`
`45.
`
`Additionally, Hawkes teaches that the token may be powered by a battery
`
`and/or via power supplied by a terminal. Ex. 1003, pages 86 and 88; Ex. 1002 at 46.
`
`Hawkes teaches that tokens or smart cards may be programmable. See Ex. 1002 at
`
`51. For example, Hawkes teaches that the RSA processor is programmed to perform
`
`RSA encryption calculations, and all remaining functions of the IC card are
`
`35414971.1
`
`
`
`-16-
`
`
`
`
`
`performed by programs executed by the control processor. Ex. 1003, pages 86-87.
`
`Additionally, Hawkes indicates that it is advantageous to use both a control
`
`processor and an RSA processor. See Ex. 1002 at 46. For example, use of different
`
`processors for applications and encryption allows the two processor to work in
`
`parallel, which reduces and/or hides the encryption calculation time. Ex. 1003,
`
`pages 86-87. Ex. 1002 at 46. Additionally, such a configuration enables the control
`
`processor to be programmed using a high-level programming language. Ex. 1003,
`
`pages 86-87. Ex. 1002 at 46.
`
`Hawkes further teaches that the integrity of transaction messages that control
`
`the movement of funds between the token user and retailer accounts is of significant
`
`importance, and teaches that the token may utilize an encryption techniques to
`
`generate signed transaction messages. Ex. 1003, pages 83, 84, 146-151. Ex. 1002 at
`
`47. To further enhance the integrity of transactions, Hawkes indicates that, during a
`
`transaction, a terminal may generate a random challenge number that may be
`
`provided to the token, and, in response, the token may generate a signed reply by
`
`signing the challenge number using an encryption technique, where the signed reply
`
`is used for identity verification. Ex. 1003, page 84, FIG. 6.1; Ex. 1002 at 47. To
`
`avoid “replays” of transactions, Hawkes teaches that a time and date field must be
`
`included in messages (e.g., transaction messages) exchanged between the token and
`
`the terminal. Ex. 1003, page 85, FIG. 6.2; Ex. 1002 at 47. Additionally, Hawkes
`
`35414971.1
`
`
`
`-17-
`
`
`
`
`
`teaches that sequence numbers are applied to transaction messages to deter message
`
`reuse, and that details of transactions which the token participates in are stored in the
`
`data memory of the token. Ex. 1003, pages 70, 86, 153; Ex. 1002 at 47.
`
`
`2.
`
`Davis
`
`Davis discloses a transaction system and method of conducting a transaction
`
`between in integrated circuit (IC) card and a transaction terminal. Ex. 1004,
`
`Abstract. In Davis, the IC card includes a microprocessor, memory (e.g., random
`
`access memory and non-volatile memory), and a plurality of electrical contacts to
`
`facilitate an electrical connection between the IC card and a terminal. Ex. 1004,
`
`3:21-41; Ex. 1002 at 52. The memory stores programs, a transaction count, a serial
`
`number, instructions for generating a random number, and at least one electronic
`
`purse that enables the IC card to be used for the purchase of goods and/or services,
`
`whereby cash value stored in the electronic purse is transferred from the IC card to a
`
`terminal in communication with the IC card. Ex. 1004, 3:37-67, 4:16-38, 11:36-64.
`
`During a purchase, a dual-challenge procedure, illustrated in FIGs. 3A-3C, is
`
`used to establish a secure session between the IC card and the terminal (e.g., a point
`
`of sale terminal). Ex. 1004, 10:21-26, 13:6-22, and FIGs. 3A-3C; Ex. 1002 at 53. If
`
`the dual-challenge procedure is successful (i.e., the random number encrypted by the
`
`IC card matches the random number provided by the terminal, and vice-versa), the
`
`IC card is authorized to execute the desired value transfer to complete the purchase.
`
`35414971.1
`
`
`
`-18-
`
`
`
`
`
`Ex. 1004, 13:23-14:51, FIGs. 3A-3C; Ex. 1002 at 53. Davis indicates that executing
`
`the value transfer includes deducting a transaction amount from an available cash
`
`value balance stored in the memory of the IC card, encrypting, by the IC card, the
`
`transaction amount to produce a verification certificate that is provided from the IC
`
`card to the terminal where it is stored in a memory of the terminal . Ex. 1004, 6:13-
`
`51, 14:22-55, FIG. 3C; Ex. 1002 at 53.
