`DECLARATION OF MICHAEL SHAMOS, PH.D., IN SUPPORT OF
`DEFENDANT’S OPENING CLAIM CONSTRUCTION BRIEF
`
`I, Michael Ian Shamos, Ph.D., do hereby declare as follows under penalty of perjury under
`
`the laws of Texas and the United States:
`
`I.
`
`INTRODUCTION
`
`1.
`
`My name is Michael Shamos. I have been retained as an expert witness by
`
`Defendant Visa U.S.A. Inc. (“Visa” or “Defendant”) in this matter.

`
`6.
`
`I currently hold the title of Distinguished Career Professor in the School of
`
`Computer Science at Carnegie Mellon University in Pittsburgh, Pennsylvania. I am a member of
`
`two departments in that School, the Software and Societal Systems Department and the Language
`
`Technologies Institute. I was a founder and Co-Director of the Institute for eCommerce at
`
`Carnegie Mellon from 1998-2004 and from 2004-2018 have been Director of the eBusiness
`
`Technology graduate program in the Carnegie Mellon University School of Computer Science.
`
`Since 2018, I have been Director of the M.S. in Artificial Intelligence and Innovation degree
`
`program at Carnegie Mellon.
`
`7.
`
`I have taught graduate courses at Carnegie Mellon in Electronic Commerce,
`
`including eCommerce Technology, Electronic Payment Systems, Electronic Voting, Internet of
`
`Things, Ubiquitous Computing, Electronic Payment Systems and eCommerce Law and
`
`Regulation, as well as Analysis of Algorithms. Since 2007, I have taught an annual course in Law
`
`of Computer Technology. I currently also teach Artificial Intelligence and Future Markets.
`
`8.
`
`I am the author and lecturer in a 24-hour video course on Internet protocols and
`
`have taught computer networking, wireless communication, and Internet architecture since 1999.

`
`
`
`9.
`
`From 2001-2021, I was a Visiting Professor at the University of Hong Kong, where
`
`I taught an annual course in Electronic Payment Systems. This is one of only a handful of graduate
`
`courses taught on this subject in the world.
`
`10.
`
`I was the Director of Carnegie Mellon’s graduate degree program in eBusiness
`
`Technology from 1999-2018 and am now a faculty member in the Privacy Engineering degree
`
`program at Carnegie Mellon. My course on Law of Computer Technology is required for all
`
`students in that program.
`
`11.
`
`I am a named inventor on the following six issued patents relating to electronic
`
`commerce: U.S. Patent Nos. 7,330,839; 7,421,278; 7,747,465; 8,195,197; 8,280,773; and
`
`9,465,299.
`
`12.
`
`From 1979-1987 I was the founder and president of two computer software
`
`development companies in Pittsburgh, Pennsylvania, Unilogic, Ltd. and Lexeme Corporation.
`
`13.
`
`I am an attorney admitted to practice in Pennsylvania and have been admitted to
`
`the Bar of the U.S. Patent and Trademark Office since 1981. I have been asked to render opinions
`
`in this Declaration as a technical expert. I have not been asked to offer any opinions on patent law
`
`in this proceeding.
`
`14.
`
`I have previously served as an expert in over 360 cases concerning computer
`
`technology. In particular, I have been involved in at least 35 cases involving electronic payment
`
`systems.
`
`III. COMPENSATION
`
`15.
`
`I am being compensated for my work in this case at the rate of $600 per hour. I am
`
`also reimbursed for all reasonable expenses that I incur during the course of this case. My
`
`compensation does not depend upon the results of my analysis or the substance of my testimony,
`
`nor does my compensation depend on the outcome of this or any related proceeding. I have no
`
`-3-
`
`
`
`Case 6:22-cv-00697-ADA Document 41-1 Filed 08/21/23 Page 4 of 98
`
`
`
`personal interest in the outcome of this matter. I have no financial interest in RFCyber Corp.
`
`(“Patent Owner”) or affiliation with any of parties in interest, the Patent Owner or the inventors of
`
`the Patents. It is conceivable that I may own mutual funds whose portfolios include stock in
`
`Defendant’s affiliate Visa, Inc. If this is the case, the value of such holding would not constitute
`
`a material part of my net worth.
`
`16.
`
`The statements made and opinions provided in this Declaration are based on my
`
`own personal knowledge and experience.
`
`17.
`
`In this Declaration, all emphasis in boldface has been added unless otherwise noted.
`
`IV. RELEVANT LEGAL PRINCIPLES
`
`18.
`
`I have been informed by counsel for Visa that the following principles of law are
`
`applicable to claim construction, and I have applied these principles in my analysis.
`
`19.
`
`The claims of a patent define the limits of the patentee’s exclusive rights. In order
`
`to determine the scope of the claimed invention, courts may construe (or define) claim terms when
`
`the meanings are disputed by the parties.
`
`20.
`
`Claim terms should generally be given their ordinary and customary meaning as
`
`understood by one of ordinary skill in the art at the time of the invention after reading the patent
`
`and its prosecution history.
`
`21.
`
`Claims must be construed, however, in light of, and consistent with, the patent’s
`
`intrinsic evidence. Intrinsic evidence includes the claims themselves, the written disclosure in the
`
`patent’s specification, and the patent’s prosecution history, including the prior art that was
`
`considered by the United States Patent and Trademark Office (“PTO”).
`
`22.
`
`The language of the claims helps guide the construction of claim terms. The context
`
`in which a term is used in the claims can be highly instructive.
`
`-4-
`
`
`
`Case 6:22-cv-00697-ADA Document 41-1 Filed 08/21/23 Page 5 of 98
`
`
`
`23.
`
`The specification of the patent is the best guide to the meaning of a disputed claim
`
`term, beyond the wording of the claims themselves. Embodiments disclosed in the specification
`
`help teach and enable those of skill in the art to make and use the invention, and are helpful to
`
`understanding the meaning of claim terms. Nevertheless, in many cases, the limitations of
`
`preferred embodiments and examples appearing in the specification should not be read into the
`
`claims.
`
`24.
`
`In the specification, a patentee may also define his own terms, give a claim term a
`
`different meaning than it would otherwise possess, or disclaim or disavow claim scope. A court
`
`may generally presume that a claim term possesses its ordinary meaning. This presumption,
`
`however, does not arise when the patentee acts as his own lexicographer by explicitly defining or
`
`re-defining a claim term. This presumption of ordinary meaning can also be overcome by
`
`statements, in the specification or prosecution history of the patent, of clear disclaimer or
`
`disavowal of a particular claim scope.
`
`25.
`
`The specification may also resolve any ambiguity if the ordinary and customary
`
`meaning of a claim term lacks sufficient clarity to permit the scope of the claim to be ascertained
`
`from the words of the claim alone.
`
`26.
`
`The prosecution history can be another important source of evidence in the claim
`
`construction analysis. The prosecution history is the record of the proceedings before the PTO,
`
`including communications between the patentee and the PTO. The prosecution history can inform
`
`the meaning of the claim language by demonstrating how the patentee and the PTO understood
`
`the invention and whether the patentee limited the invention in the course of prosecution, making
`
`the claim scope narrower than it would otherwise be. A patentee may also define a term during
`
`the prosecution of the patent. The patentee is precluded from recapturing through claim
`
`-5-
`
`
`
`Case 6:22-cv-00697-ADA Document 41-1 Filed 08/21/23 Page 6 of 98
`
`
`
`construction specific meanings or claim scope clearly and unambiguously disclaimed or
`
`disavowed during prosecution.
`
`27.
`
`Courts can also consider extrinsic evidence when construing claims. Extrinsic
`
`evidence is any evidence that is extrinsic to the patent itself and its prosecution history. Examples
`
`of extrinsic evidence include technical dictionaries, treatises, and expert testimony. I understand
`
`that extrinsic evidence is less significant than the intrinsic record in determining the meaning of
`
`claim language, and that a court should discount extrinsic evidence that is at odds with the intrinsic
`
`record.
`
`28.
`
`I understand that the patent claims can be invalidated for indefiniteness when they
`
`simultaneously claimed a product and a method of using it.
`
`29.
`
`I further understand that if the patent claims, read in light of the specification and
`
`the prosecution history, fail to inform, with reasonable certainty, those skilled in the art about the
`
`scope of the invention, they are invalid for indefiniteness. I understand that “reasonable certainty”
`
`does not require absolute precision in the language of the claims. Rather, the claims must be
`
`precise enough to give clear notice of what is claimed and what is still available in the public
`
`domain. I also understand that when analyzing definiteness, the claims must be interpreted from
`
`the perspective of a person of ordinary skill in the art at the time the invention was made in light
`
`of the specification and prosecution history.
`
`V.
`
`LEVEL OF ORDINARY SKILL IN THE ART
`
`30.
`
`It is my understanding that my analysis of the interpretation of a claim term must
`
`be undertaken from the perspective of what would have been known or understood by a person
`
`having ordinary skill in the art (“POSITA”) at the time of the invention. In determining the
`
`appropriate level of ordinary skill in the art in this case, I have been instructed that various factors
`
`may be considered, including the type of problems encountered in the art, prior art solutions to
`
`-6-
`
`
`
`Case 6:22-cv-00697-ADA Document 41-1 Filed 08/21/23 Page 7 of 98
`
`
`
`those problems, the rapidity with which innovations are made, the sophistication of the technology,
`
`and the educational level of active workers in the field. I have considered these factors in my
`
`analysis.
`
`31.
`
`It is my opinion that a POSITA would have a bachelor’s degree in computer
`
`science, computer engineering, or equivalent, with one year of experience relating to mobile
`
`technology or electronic payment technology. A person of ordinary skill in the art could have less
`
`formal education if that person had additional years of relevant professional experience.
`
`32.
`
`I understand that the Patents claim priority to U.S. Patent Application No.
`
`11/534,653, filed on September 24, 2006, although any given claim of those Patents may not be
`
`entitled to the that date. I also understand that Visa contends that the ’009 Patent is not entitled to
`
`a priority date any earlier than January 16, 2012.
`
`33.
`
`I also understand that RFCyber contends that each of the Patents has a priority date
`
`at least as early as July 1, 2004.
`
`34.
`
`At all times, I have understood and interpreted the claims of the Patents from the
`
`point of view of a POSITA as of the 2006 timeframe with respect to the ’218, ’855, and ’787
`
`Patents, and as of the 2012 timeframe with respect to the ’009 Patent. However, the opinions set
`
`forth in this Declaration would not change if the Court were to determine that one or more of the
`
`Patents were entitled to a priority date as early as 2004.
`
`VI.
`
`TECHNOLOGICAL BACKGROUND
`
`U.S. Patent Nos. 8,118,218, 8,448,855 and 9,189,787
`
`35.
`
`The ’218, ’855, and ’787 Patents share a common specification and describe an e-
`
`purse on a smart card mobile phone or other portable device, which allows the device to conduct
`
`-7-
`
`
`
`Case 6:22-cv-00697-ADA Document 41-1 Filed 08/21/23 Page 8 of 98
`
`
`
`secure payment transactions with a payment server. ’218 Patent at 1:6-22, 1:34-38, Fig. 2.1. The
`
`Patents refer to an e-purse as a “single functional card” having “stored values,” i.e., electronic
`
`money, for performing “micro payment transactions.” Id. at 1:14-17, 1:23-27, 3:51-55, 3:61-63,
`
`4:2-7, 4:62-64. The Patents acknowledge that “[s]ingle functional cards have been successfully
`
`used in enclosed environments such as transportation systems” and highlight the MIFARE card as
`
`having been a widely used e-purse. Id. at 1:13-22. They assert, however, that “such enclosed
`
`systems are difficult to be expanded into other areas such as e-commerce and m-commerce because
`
`stored values and transaction information are stored” in a way that is “protected by a set of keys,”
`
`and “the keys need to be delivered to the card for authentication before data can be accessed during
`
`a transaction.” Id. at 1:23-29. The Patents assert that there is “a need for a mechanism in devices,
`
`especially portable devices, functioning as an electronic purse (e-purse) to be able to conduct
`
`transactions over an open network with a payment server without compromising security.” Id. at
`
`1:34-38.
`
`36.
`
`The Patents’ purported solution is to provide “a mechanism to be embedded” in the
`
`portable device to function as an e-purse and provide the necessary security. Id. at 2:42-46. That
`
`“mechanism” is a smart card. Id. at 2:10-41. A “smart card” is one having a computer processor,
`
`The smart card comes with a preloaded operating system, such as Java Card Open Platform
`
`(“JCOP”), which provides “a general security framework,” such as the GlobalPlatform standard,
`
`for “card personalization.” Id. at 4:8-22, 4:41-46, 4:50-56. The operating system’s security
`
`
`
`1 Because the Asserted Patents share a specification, references to the ’218 patent
`specification and figures encompass the corresponding portions of the other two as well unless
`otherwise specified.
`
`-8-
`
`
`
`Case 6:22-cv-00697-ADA Document 41-1 Filed 08/21/23 Page 9 of 98
`
`
`
`“control[s] the access to the smart card (e.g., an installation of external applications into the smart
`
`card).” Id. at 4:47-50.
`
`37.
`
`The Patents explain that “multiple application smart cards” – including the well-
`
`known SmartMX smart card by Philips – can also come “pre-loaded with an emulator,” such as a
`
`MIFARE emulator, allowing the multi-application smart card to mimic (or “emulate”) single
`
`functional cards such as a MIFARE transit card for use with MIFARE readers. Id. at 2:14, 2:27-
`
`28, 3:51-60, 4:62-64, Fig. 2.
`
`38.
`
`The ’218, ’855, and ’787 Patents teach that a smart card, including an e-purse applet
`
`or emulator in the smart card, can be personalized using a GlobalPlatform card manager to enable
`
`a secure channel to be established between the e-purse and a server. Id. at 4:11-22, 5:50-54.
`
`Personalization involves loading a specific user’s data into the e-purse, e.g., the user’s account
`
`information, “operation keys (e.g., a load key and a purchase key), default PINs, administration
`
`keys (e.g., an unblock PIN key and a reload PIN key), and passwords (e.g., from Mifare).” Id. at
`
`5:54-59. Smart cards that comply with the GlobalPlatform standard have at least one security
`
`domain that “includes three 3DES keys,” which are encryption keys that are “used to generate
`
`session keys for a secured session between two entities,” i.e., a security channel. Id. at 6:29-47,
`
`Fig. 3C. The security domain and encryption keys are “installed by a card issuer.” Id. at 6:48-54.
`
`Another set of keys can also be generated and distributed to the e-purse applet to secure subsequent
`
`operations. Id. at 6:55-7:9, Fig. 3C.
`
`39.
`
`The ’218, ’855, and ’787 Patents also describe a process for funding the e-purse,
`
`which is a necessary step in using it to conduct transactions. Id. at 7:10-13, 8:7-12, Figs. 4A-4C.
`
`After a valid PIN entry, a midlet initiates an over-the-air (“OTA”) “top off request,” sending a
`
`request to the e-purse applet. Id. at 7:22-28, Fig. 4A. The e-purse applet composes a response to
`
`-9-
`
`
`
`Case 6:22-cv-00697-ADA Document 41-1 Filed 08/21/23 Page 10 of 98
`
`
`
`the request, which is sent via the midlet to “a payment network and server over a wireless network.”
`
`Id. at 7:29-32, Fig. 4A. The response is verified and a bank account at a financial institution is
`
`then verified. Id. at 7:35-44, Fig. 4A. A response is then sent back to the midlet, after which
`
`commands are extracted from the response and sent to the e-purse. Id. at 7:45-48, Fig. 4B. The
`
`e-purse verifies the commands and then updates the emulator and transaction logs to reflect the
`
`updated stored value. Id. at 7:48-51, Fig. 4B.
`
`U.S. Patent No. 9,240,009
`
`
`
`40.
`
`The ’009 Patent is a continuation-in-part of the ’218 Patent and describes mobile
`
`devices with “secure elements” that can securely host “an application such as an electronic purse”
`
`for conducting secured transactions over a network. ’009 Patent, at 1:18-24. The ’009 Patent
`
`includes the disclosures found in the shared specification of the ’218, ’855, and ’787 Patents, as
`
`well as additional disclosures and figures.
`
`41.
`
`The ’009 Patent states: “[T]here is a need to provide techniques to personalize a
`
`secure element in a contactless smart card or an NFC-enabled mobile device so that such a device
`
`is so secured and personalized when it comes to financial applications or secure transactions. With
`
`a personalized secure element in an NFC-enabled mobile device, various applications or services,
`
`such as electronic purse or payments, can be realized.” Id. at 2:10-17.
`
`42.
`
`The ’009 Patent teaches that, when a mobile device is obtained, the secure element
`
`(“SE”) “is installed with a set of default keys (e.g., an Issuer Security Domain (ISD) key set by the
`
`SE manufacturer).” Id. at 6:55-58, 8:46-48. “[A] standard-compliant secure element comes with
`
`one issuer security domain (ISD) and an option for one or more supplemental security domains
`
`(SSD). Each of these domains includes a set of keys.” Id. at 7:1-4.
`
`43.
`
`The ’009 Patent explains that the “SE 102 needs to go through a personalization
`
`process before it can be used.” Id. at 7:13-14. “The personalization process can be done either
`
`-10-
`
`
`
`Case 6:22-cv-00697-ADA Document 41-1 Filed 08/21/23 Page 11 of 98
`
`
`
`physically in a service center or remotely via a web portal by a TSM server.” Id. at 7:49-51. A
`
`“TSM, standing for Trusted Service Management, is a collection of services” that can “help service
`
`providers securely distribute and manage contactless services for their customers using the
`
`networks of mobile operators.” Id. at 7:35-39. The default “device information (e.g., ISD) of the
`
`SE” can be used to derive personalized keys to personalize the SE. Id. at 8:57-9:23. “After the
`
`personalization, the SE can only be accessed using the personalized ISD key of the SE issuer.
`
`Depending on the security requirement of each service provider, the TSM can create additional
`
`SSDs for the various providers to personalize their respective applications (e.g., the modules 104
`
`or 106 of FIG. 1A).” Id. at 9:24-29.
`
`44.
`
`The ’009 Patent describes “an e-token enabled device,” such as “a single functional
`
`card or a portable device enabled with an e-purse,” that “may represent e-money, e-coupons, e-
`
`ticket, e-voucher or any other forms of payment tokens in a device.” Id. at 20:44-50. Transactions
`
`using the e-token device may occur in “real time” and “offline (i.e., without the portable device
`
`connecting to a backend POS transaction server.” Id. at 20:51-58; see also id. at Figs. 6A-6D.
`
`Figure 6D depicts “a flowchart illustrating an exemplary process [] of conducting m-commerce
`
`using a portable device.” Id. at 22:48-56, Fig. 6D. The ’009 Patent explains that transactions using
`
`the e-purse may be evaluated against the value stored on the e-purse to determine whether to
`
`approve or deny the transaction or to allow the user to “top-up” and attempt re-processing. Id. at
`
`22:57-23:20, Figs. 6C and 6D.
`
`VII. TERMS IN DISPUTE
`
`45.
`
`I have been asked to provide my opinions on the term addressed below as well as
`
`to respond to RFCyber’s proposed constructions.
`
`A.
`
`“fund” / “fund stored in the emulator”
`
`
`
`-11-
`
`
`
`Case 6:22-cv-00697-ADA Document 41-1 Filed 08/21/23 Page 12 of 98
`
`
`
`46.
`
`I understand that RFCyber’s proposed construction of these terms is “plain and
`
`ordinary meaning except for ‘emulator.’”
`
`47.
`
`However, I also understand that RFCyber has alleged, for example, that
`
`“consumable keys or tokens” can comprise “a fund stored in an emulator.” A person of ordinary
`
`skill in the art at the time of the alleged invention would not understand funds to include
`
`“consumable keys or tokens,” including as the term is used in the shared specification of the
`
`Patents, as discussed further below. The term “funds” refers to money. A key or token is not
`
`money. In the electronic payment context, a token is a substitute for a sensitive data element
`
`(which is a data element, such as a credit card number, that should be kept private or secret). A
`
`token is not funds, which a person of ordinary skill in the art would understand comprise money
`
`or a balance of money, as discussed further below. A token does also not represent funds.
`
`Therefore, in my opinion, RFCyber’s position as to the meaning of “fund” terms is not the plain
`
`and ordinary meaning of those terms.
`
`48.
`
`One of ordinary skill in the art at the time of the alleged invention of the Patents
`
`would have understood the term “fund” (as a noun) to mean a money balance and to “fund” (as a
`
`verb) to mean to add to a money balance. This is summarized with respect to the “fund” terms
`
`below:
`
`Term and Claims
`“fund” / “fund stored in the emulator”
`
`Meaning
`“money balance” / “money balance stored in
`the emulator”

`’218 Patent, Claims 10, 18
`’855 Patent, Claim 1, 4, 13
`
`
`“add / added / adding money balance to”

`
`The terms appear in the following claim language:

`
`Claim Language
`
`’218 Patent, Claims 10 and 18
`
`“the e-purse is funded through a financial institution that
`maintains an account for a user”
`
`’855 Patent, Claims 1 and 9
`
`“A method for funding an e-purse”
`
`“a fund transfer request is initiated by the server to the
`financial institution” / “initiating a fund transfer request by a
`server with a financial institution”
`
`“responding to the fund transfer request”
`
`’855 Patent, Claims 4 and 13
`
`“to regulate or control data exchange between the server and
`the portable device for funding the e-purse therein”
`
`’787 Patent, Claims 1 and 11
`
`“to perform electronic commerce with the e-purse applet
`against a fund stored in the emulator”
`
`“to perform mobile commerce with a payment server via an
`application against the fund stored in the emulator” /
`“performing mobile commerce via a second interface with a
`payment server via an application against the fund stored in
`the emulator”
`
`
`
`50.
`
`The shared specification of the ’218,’855, and ’787 Patents uses the word “fund”
`
`three times, and each time it is in the context of adding money to the balance of the e-purse—not
`
`in making a purchase. The first use of the term is to begin the description of funding the e-purse
`
`from a bank account in connection with a flowchart in FIG. 4: “The user desires to fund the e-
`
`purse from an account associated with a bank.” ’218 Patent at 7:20-22.
`
`51.
`
`The shared specification refers to the process of funding the e-purse as “an OTA
`
`top off request.” This helps to shape my understanding that “fund” means a money balance or
`
`adding to a money balance.
`
`52. More specifically, the shared specification continues on to say that “[a]t 402, the
`
`user enters a set of personal identification numbers (PIN). Assuming the PIN is valid, a purse
`
`manger in the device is activated and initiates a request (also referred to an OTA top off request)

`
`
`Case 6:22-cv-00697-ADA Document 41-1 Filed 08/21/23 Page 14 of 98
`
`
`
`at 404. The midlet in the device sends a request to the e-purse applet at 406, which is illustrated
`
`in FIG. 4C where the e-purse manager midlet 434 communicates with the e-purse applet 436.”
`
`’218 Patent at 7:20-28. A “top off” is the act of refilling the money balance on the card, which is
`
`consistent with my understanding of the term “fund.” Like “topping off” a gas tank, it means to
`
`actually add money to the card; it does not refer to any and every activity that could relate to a card
`
`being used in a transaction.
`
`53.
`
`The next use of the term “fund” is also in the context of adding money to the balance
`
`of the e-purse from the bank account. The shared specification states that “[i]f the account does
`
`exist, a fund transfer request is initiated. At 414, the bank receives the request and responds to
`
`the request by returning a response. In general, the messages exchanged between the payment
`
`network and server and the bank are compliant with a network protocol (e.g., HTTP for the
`
`Internet).” ’218 Patent at 7:29-44. Here again, “fund” means adding a money balance to the
`
`device. The “messages exchanged” between “the payment network and server and the bank” make
`
`clear that the bank can transfer funds to the device. This is also consistent with my understanding
`
`that a fund transfer request is not the same as a request to complete a purchase made using the e-
`
`purse, which is further consistent with the discussion of “fund” below.
`
`54.
`
`Finally, the shared specification concludes the description of the flowchart in FIG.
`
`4, stating: “Although the process 400 is described as funding the e-purse. [sic]Those skilled in
`
`the art can appreciate that the process of making purchasing over a network with the e-purse is
`
`substantially similar to the process 400, accordingly, no separate discussion on the process of
`
`making purchasing is provided.” The specification could not be clearer: “funding” is separate and
`
`distinct from making a purchase.

`
`
`
`55.
`
`In light of the claim language and the specification discussed above, a person of
`
`ordinary skill in the art would understand “fund” to mean adding or storing a money balance.
`
`B.
`
`
`
`

`
`Each Asserted System Claim Is Indefinite for Covering Both an Apparatus
`and a Method of Using the Apparatus
`
`1.
`
`Indefiniteness of ’218 Patent Claims 11-18
`
`It is my opinion that a person of ordinary skill in the art would not understand the
`
`scope and meaning of claim 11 of the ’218 Patent because it claims both a “portable device” and
`
`a method of using the “portable device.” Because claims 12-18 depend from claim 11, it is my
`
`opinion that a person of ordinary skill in the art would also not understand the scope and meaning
`
`of those claims.
`
`57.
`
`Independent claim 11 of the ’218 Patent reads as follows:
`
`11. A system for providing an e-purse, the system comprising:
`
`a portable device including or communicating with a smart card
`pre-loaded with an emulator configured to execute a request from
`and provide a response an e-purse applet is configured to expect,
`the portable device including a memory space loaded with a midlet
`that is configured to facilitate wireless communication between the
`e-purse applet in the smart card and a payment server over a
`wireless network, the portable device further including a
`contactless interface that facilitates communication between the e-
`purse applet in the smart card and the payment server over a wired
`network, wherein the e-purse applet is downloaded from the
`payment server when the smart card is in communication with
`the payment server, and operations of personalizing the e-purse
`applet comprises:
`
`establishing an initial security channel between the smart card and
`the e-purse security authentication module (SAM) to install and
`personalize the e-purse applet in the smart card, and
`
`creating a security channel on top of the initial security channel to
`protect subsequent operations of the smart card with the e-purse
`SAM, wherein any subsequent operation of the emulator is
`conducted over the security channel via the e-purse applet;
`
`the payment server associated with an issuer authorizing the e-
`purse applet; and
`
`the e-purse SAM configured to enable the e-purse applet, wherein
`an SAM is behind the payment server and in communication with
`
`-15-
`
`
`
`Case 6:22-cv-00697-ADA Document 41-1 Filed 08/21/23 Page 16 of 98
`
`
`
`the e-purse applet when the e-purse applet is caused to
`communicate with the payment server via the midlet.
`
`58.
`
`Although the claim is to a “system comprising: a portable device,” the claim also
`
`includes a method step in which the “e-purse applet is downloaded.”
`
`59.
`
`It is my opinion that a person of ordinary skill in the art at the time of the invention
`
`would not know whether infringement occurs when the portable device is manufactured (and
`
`perhaps capable at that point of downloading an e-purse applet from the payment server), or if
`
`infringement occurs only if, or after, the e-purse applet is actually downloaded. The manufacture
`
`and sale of a portable device, such as one claimed in claim 11 of the ’218 Patent, often if not always
`
`occurs prior to the “downloading” of software onto the device at the time of the alleged invention.
`
`Software could and would be loaded onto such devices prior to sale through methods other than
`
`downloads from a network. It would be unclear from the claim to a person of ordinary skill in the
`
`art whether devices as they were typically manufactured and sold would infringe.
`
`60.
`
`The limitation that the downloading occurs “when the smart card is in
`
`communication with the payment server” further confirms that this is a method step that could
`
`(and usually would) occur separately from the manufacture or sale of the device. The specification
`
`describes communication with the payment server occurring “over an open network.” ’218 Patent
`
`at 1:36-37. A person of ordinary skill in the art would have known that communications over an
`
`open network must occur after manufacture and sale of a portable device, and not as part of the
`
`manufacturing process.
`
`61.
`
`The prosecution history also confirms that the downloading is a process step that
`
`makes unclear whether the portable device infringes when made or only infringes after the
`
`downloaded recited process is performed. During prosecution, the applicant pointed to a specific
`
`paragraph of its application as support for adding this limitation. See App. 11/534,653 9/7/2011

`Amendment at 8-9, 12. That corresponding paragraph describes the process when “a user desires
`
`to personalize an e-purse embedded in a device (e.g., a cellphone).” ’218 Patent at 5:60-61. This
`
`indicates that the down
