`bolding) appearing in all quotations herein has been added. For readability
`
`(reducing parenthetical notices), this is not always indicated.

`
`generally abbreviated to just “teach” for readability.

`
`
`
`
`
`1. Overview.
`
`The challenged claims recite a notification event associated with “an action”
`
`that
`
`“requires”
`
`acknowledgement by
`
`the user
`
`(and
`
`receiving
`
`such
`
`acknowledgement). Not all events require acknowledgment by users even if the
`
`user is notified of them. Notifying a user of a stock update, for example, is not
`
`associated with an action that requires user acknowledgement. The Board has
`
`determined on more than one occasion that Bennett does not teach the recited
`
`“notification event” limitations of the claims. The last element of claim 1 is a
`
`notification-event
`
`limitation,
`
`reciting
`
`“receiving,
`
`from
`
`the user,
`
`an
`
`acknowledgement of an action associated with the established notification event.”
`
`The Petition does not argue that Campbell teaches this element—it relies on
`
`Bennett alone. TeleSign’s claims should not be found unpatentable because:
`
`1. the Petition fails to substantively analyze the “action” limitations and
`
`show that they are taught in the prior art (rather, it focuses only on
`
`“notification events”);
`
`2. the Petition fails to distinguish notification events that are associated
`
`with actions that require user acknowledgement from those that do
`
`not;
`
`3. the Petition fatally relies on Bennett alone to show the last element of
`
`claim 1, a notification-event limitation, setting forth no argument at all
`
`8107716
`
`Page 1
`
`
`
`
`
`that Campbell purportedly teaches “receiving, from the user, an
`
`acknowledgement of an action associated with the established
`
`notification event”;
`
`4. Petitioner is not allowed to make additional arguments outside of the
`
`Petition to support its prima facie case;
`
`5. In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1375 (Fed. Cir.
`
`2016), for example, discharges responsibility from and even prevents
`
`the Board from setting forth additional arguments that are not in the
`
`Petition; and
`
`6. skilled artisans would not have been motivated to combine the
`
`teachings of Bennett and Campbell, and thus, Petitioner has failed to
`
`show that any notification-event limitation is taught.
`
`2.
`
`The ’792 Patent.
`
`The ’792 patent describes preventing fraudulent, fake online registrations by,
`
`among other things, first verifying a potential registrant’s submitted information.
`
`Thus, claim 1 recites “completing” a registration of users based on information
`
`received from a user and on a verification of a telephone number by a verification
`
`process. Fraudsters attempt to commit fraud online when they try to create online
`
`accounts using false information for their advantage. This sort of fraud “can
`
`compromise the intended purpose of the registration, create a breach of security
`
`8107716
`
`Page 2
`
`
`
`
`
`and constitute fraud on the web-site owners.” Ex. 1001 at 1:58-60. It includes
`
`attempting to obtain access to an existing account or other information that the
`
`fraudster is not authorized to access.
`
`Fraudsters also try to commit fraud by portraying themselves as legitimate
`
`users. They may try to, for example, withdraw large sums of money or charge
`
`expensive items to credit cards. The ’792 patent also, among other things,
`
`describes and claims transmitting messages to legitimate users upon the occurrence
`
`of notification events. The invention maintains a record of notification events that
`
`are associated with actions that require acknowledgement by the user. It is these
`
`actions that require acknowledgement by the user.
`
`2(A). Problems Addressed by the ‘792 Patent.
`
`The ’792 patent addresses a multifaceted problem:
`
`1. in an online environment, potential registrants often register using
`
`false information;1
`
`2. permitting fraudulent online registrations can create a breach of
`
`security;2
`
`3. security measures need to be rapidly and reliably deployed while still
`
`providing “an additional layer of security”3; and
`
`
`1 Ex. 1001 at 1:56-58.
`
`2 Ex. 1001 at 1:58-60.
`
`3 Ex. 1001 at 8:45-47; 2:17-25.
`
`8107716
`
`Page 3
`
`
`
`
`
`4. legitimate users do not learn about unauthorized activity or attempted
`
`activity soon enough to address it.4
`
`These problems are rooted in computer technology. Brick-and-mortar stores
`
`allow for face-to-face interactions. Online presences do not. Thus, determining
`
`whether remotely provided digital information over the Internet is accurate was
`
`(and is) a problem—a significant technological problem. As mentioned, a key
`
`aspect of fraud explained in the specification relates to identifying potentially
`
`fraudulent website registrations.5
`
`The problem stems from the rise of the Internet and the anonymity of
`
`communicating via remote network connections. Parties exchange data online
`
`without being physically present. Information is received electronically. Users
`
`desire to create online registrations. But users can provide false registration
`
`information.6 And allowing fraudulent (or fake) registrations could “compromise
`
`
`4 Ex. 1001 at 1:61-2:8.
`
`5 The title of the patent includes “Registration.” The specification (including
`
`claims and references to prior applications) refers to some form of “registration,”
`
`“registrant,” “register” or the like 326 times (a word search of “regist” yields 326
`
`hits). Both independent claims recite “completing a registration of the user based
`
`on” recited information. Ex. 1001 at claims 1 and 10.
`
`6 Ex. 1001 at 1:56-58; Ex. 2001 at 5 (Social media website Facebook, for
`
`example, may have over 14 million accounts that are “fakes created for spam” or
`
`
`
`8107716
`
`Page 4
`
`
`
`
`
`the intended purpose of the registration” and lead to security breaches. Ex. 1001 at
`
`1:58-60. But then again, attempting to separate legitimate requests from fraudulent
`
`attempts could take so long that it is not practical. For legitimate users, the
`
`problem of notifying them of unauthorized activity or attempted activity (such as
`
`altering account information)7 in time for it to be addressed existed.
`
`As reflected in more modern literature and consistent with the specification
`
`of the ’792 patent: “Fake accounts operated by low-paid humans or automated
`
`software have become good business, too. They are used to inflate follower counts,
`
`to push spam or malware, and even to skew political discourse. The tactic appears
`
`to be pervasive and growing in sophistication.” Ex. 2002 at 1.
`
`2(B). Solutions.
`
`The
`
`inventors addressed
`
`the
`
`technological problems above with
`
`technological solutions. The ’792 patent contemplates a computing system that
`
`employs software to implement or perform a “verification and notification
`
`method.”8 Ex. 1001 at claims 1 and 10. The solution, as a whole, reduces
`
`fraudulent online registrations in a rapid manner using a combination of hardware
`
`
`other undesired purposes.).

`and software to provide a verification and notification method implemented by a
`
`computing system that helps verify the accuracy of registration information—
`
`completing a registration based on a verified telephone number. Id. at Abstract,
`
`2:29-41, 5:3-7, 12:41-13:2, 13:23-14:17.
`
`Information is received from a user via a computing interface (such as an
`
`online web registration form) presented to the user attempting to access a service.
`
`Id. at 2:42-43, 4:51-55, 5:28-29, 5:57-60, 6:27-29, 7:9-13, 7:47-51, 8:8-12, 9:7-9,
`
`12:43-46, 13:27-30. The received information can include a telephone number
`
`associated with the user. Id. at 4:55-58, 5:28-29, 6:27-29, 7:9-13, 9:9-13, 12:45-
`
`46, 13:29-30. The telephone number is verified; for example, using a verification
`
`code sent in real time to the user, such as via SMS. Id. at Abstract, 7:15-18, 9:25-
`
`28, 9:33-35. A verification code submitted by the user is received via the
`
`computing interface. Id. at 4:63-65; 12:52-53, 13:36-37. The telephone number is
`
`deemed verified if the submitted verification code is the same as the communicated
`
`verification code. Id. at 7:1-7, 12:54-53, 14:1-3.
`
`Registration of the user is completed based on the received information and
`
`verified telephone number, which enables the user to access the service the user
`
`was attempting to access. Id. at Abstract, 9:37-43, 12:57-60, 14:4-7. A record of
`
`notification events is maintained. Id. at Abstract, 2:66-3:3, 12:61-63, 14:8-10. The
`
`notification events are associated with actions that must be acknowledged by the
`
`8107716
`
`Page 6
`
`
`
`
`
`user. Id. at Abstract, 1:65-67; 2:3-8, 10:66-11:4, 11:16-18, 12:61-63, 14:8-10.
`
`When an indication is received that a notification event has occurred, a message
`
`indicating the occurrence of the notification event is transmitted. Id. at Abstract,
`
`3:4-10, 10:2-4; 12:64-67, 14:11-14. An acknowledgement of an action associated
`
`with the notification event is received from the user. Id. at Abstract, 13:1-2, 14:14-
`
`15. This user acknowledgement allows a transaction to occur. Id. at Abstract,
`
`1:65-67; 2:3-8, 10:66-11:10, 11:16-18.

`
`Legal Authority
`
`3(A). That references merely could be combined is insufficient to show
`obviousness based on those references.
`
`Merely determining that two references could be combined is insufficient to
`
`support an obviousness finding: “[T]hat reasoning seems to say no more than that a
`
`skilled artisan, once presented with the two references, would have understood that
`
`they could be combined. And that is not enough: it does not imply a motivation to
`
`pick out those two references and combine them to arrive at the claimed
`
`invention.”9 The Federal Circuit has consistently rejected testimony directed to
`
`whether references could be combined: “Dr. Yanco’s testimony primarily
`
`consisted of conclusory references to her belief that one of ordinary skill in the art

`

`
`8107716
`
`Page 7
`
`
`
`
`
`could combine these references, not that they would have been motivated to do
`
`so.”10 “[T]he expert’s testimony on obviousness was essentially a conclusory
`
`statement that a person of ordinary skill in the art would have known, based on the
`
`‘modular’ nature of the claimed components, how to combine any of a number of
`
`references to achieve the claimed inventions. This is not sufficient and is fraught
`
`with hindsight bias.”11 Expert testimony is also deficient if it “fails to explain why
`
`a person of ordinary skill in the art would have combined elements from specific
`
`references in the way the claimed invention does.”12
`
`3(B). Hindsight is improper.
`
`“Among the difficult challenges of applying the doctrine of obviousness is
`
`avoidance of even a hint of hindsight. Obviousness cannot be based on the
`
`hindsight combination of components selectively culled from the prior art to fit the
`
`parameters of the patented invention.”13 “Without any explanation as to how or

`
`
`
`why the references would be combined to arrive at the claimed invention, we are
`
`left with only hindsight bias that KSR warns against.”14
`
`“Absent some articulated rationale, a finding that a combination of prior art
`
`would have been ‘common sense’ or ‘intuitive’ is no different than merely stating
`
`the combination ‘would have been obvious.’ Such a conclusory assertion with no
`
`explanation is inadequate to support a finding that there would have been a
`
`motivation to combine. This type of finding, without more, tracks the ex post
`
`reasoning KSR warned of and fails to identify any actual reason why a skilled
`
`artisan would have combined the elements in the manner claimed.”15
`
`“The inventor’s own path itself never leads to a conclusion of obviousness;
`
`that is hindsight.”16 “[T]he path that leads an inventor to the invention is expressly
`
`made irrelevant to patentability by statute.”17 The statute says: “Patentability shall
`
`not be negatived by the manner in which the invention was made.”18 “Defining the
`
`problem in terms of its solution reveals improper hindsight in the selection of the

`
`prior art relevant to obviousness…[because] [o]ften the inventive contribution lies
`
`in defining the problem in a new revelatory way.”19 The Federal Circuit has
`
`warned of hindsight where “it appear[ed] that the expert relied on the…patent itself
`
`as her roadmap” because that would amount “to fall[ing] victim to the insidious
`
`effect of a hindsight syndrome wherein that which only the inventor taught is used
`
`against its teacher.”20
`
`One form of improper hindsight is analyzing what merely could have been
`
`done, as discussed above. “[T]he expert’s testimony on obviousness was
`
`essentially a conclusory statement that a person of ordinary skill in the art would
`
`have known…how to combine any of a number of references to achieve the
`
`claimed inventions. This is not sufficient and is fraught with hindsight bias.”21
`
`“[W]e cannot allow hindsight bias to be the thread that stitches together prior art
`
`patches into something that is the claimed invention”.22

`3(C). Failure to articulate an adequate obviousness rationale is
`reversible error.
`
`The Board must make a finding regarding motivation to combine prior art
`
`references when it is disputed (as it is here).23 The Board “must articulate a reason
`
`why a PHOSITA would combine the prior art references.”24 The reasoning must
`
`include an “adequate evidentiary basis” and “a satisfactory explanation . . .
`
`including a rational connection between the facts found and the choice made.”25
`
`Failure to articulate logical and rational reasons for a decision is reversible error.26
`
`“[T]he PTAB’s motivation to combine ‘analysis should be made explicit’”.27
`
`“[K]nowledge of a problem and motivation to solve it are entirely different from
`
`motivation to combine particular references to reach the particular claimed
`
`method.”28

`3(D). In inter partes review, the Petitioner’s burden to show obviousness
`never shifts to the Patent Owner and the Petition must be
`complete.
`
`“In an inter partes review, the burden of persuasion is on the petitioner to
`
`prove ‘unpatentability by a preponderance of the evidence,’ 35 U.S.C. § 316(e),
`
`and that burden never shifts to the patentee.”29 The burdens of persuasion and
`

`
`Petitioner’s evidence supporting its case of obviousness, the Board is to consider
`
`all evidence together to determine whether a prima facie case of obviousness has
`
`been made by the Petitioner. The Federal Circuit has held that rebuttal evidence
`
`produced by the Patent Owner is evaluated, and if it is of “adequate weight,” any
`
`finding of prima facie obviousness is “dissipated.”32 The same court, citing from
`
`an earlier Federal Circuit case, stated
`
`that “The objective evidence of
`
`unobviousness is not evaluated for its ‘separate knockdown ability’ against the
`
`‘stonewall’ of the prima facie case…but is considered together with all other
`
`evidence, in determining whether the invention as a whole would have been
`
`obvious to a person of ordinary skill in the field of the invention.”33 Importantly,
`
`when a conclusion as to obviousness has previously been made and rebuttal
`
`evidence is produced by the Patent Owner, the facts from both the Petitioner and
`
`the Patent Owner should be laid alongside each other for evaluation, without

`
`Arguments herein are applicable to like elements in claims 1 and 10.
`
`The wording of claim elements 1[d], 1[e], and 1[f] (“maintaining,” “upon
`
`receiving,” and “receiving”) is the same as the last three elements of claim 10.
`
`Thus, all arguments and evidence herein directed to the elements of claim 1 apply
`
`with equal force to those of claim 10, but for readability and brevity, such
`
`duplicate references are not repeated throughout this document. In short, all

`
`Acknowledgment of the Board’s claim construction of “notification
`event”
`
`The Institution Decision again construes “notification event” as being “an

`
`stating that “When prima facie obviousness is established and evidence is
`
`submitted in rebuttal, the decision-maker must start over.... An earlier decision
`
`should not, as it was here, be considered as set in concrete, and applicant's rebuttal
`
`evidence then be evaluated only on its knockdown ability. Analytical fixation on
`
`an earlier decision can tend to provide that decision with an undeservedly
`
`broadened umbrella effect.).

`
`event that results in the user being notified that the event occurred.” Dec. at 10.
`
`The Board construed “notification event” in the same way in its two prior
`
`Decisions denying institution of inter partes review of related cases.35 See Ex.
`
`2004, pp. 7-11 and Ex. 2005, pp. 7-11. Thus, in three decisions, for purposes of
`
`inter partes review, the Board has construed “notification event” the same way.
`
`Dec. at 6-7, 10.
`
`Patent Owner’s analysis herein applies that construction. If this construction
`
`changes, Patent Owner would require notice and an adequate opportunity to
`
`substantively address the issues associated with a changed construction to avoid a
`
`due-process violation.

`
`Bennett does not teach the “notification event” limitations.
`
`Even in the related IPRs, the Board made clear that Bennett does not teach a
`
`“notification event,” and even stated that Dr. Shamos’ testimony is “incorrect”
`
`when Dr. Shamos quotes the text of Bennett as stating that the user is notified
`
`and/or verified by the system when a previously established notification event
`
`occurs. See, e.g., Ex. 2004, p. 10.
`
`Bennett does not expressly or inherently disclose the “notification event”
`
`
`35 See IPR2016-00451 (Paper 17) and IPR2016-00450 (Paper 17).

`limitations of the claims. Bennett’s completion code is not sufficient.36 Patent
`
`Owner has explained this in its Preliminary Response in this case and in the
`
`aforementioned two related IPRs.37
`
`As confirmed by the Board: “based on the current record, we are not
`
`persuaded that Bennett discloses, expressly or inherently, the ‘notification event’
`
`limitations of the claims.” Dec. at 17 (further noting that the “Board similarly
`
`found in related Cases IPR2016-00450 and IPR2016-00451 that Petitioner had not
`
`shown that Bennett discloses “notification events.”). The “notification event
`
`limitations” including the following (which are not taught by Bennett):
`
`• “maintaining a record of one or more notification events associated
`
`with actions that require acknowledgement by the user”;38
`
`• “upon receiving an indication of an occurrence of an established
`
`notification event, transmitting a message addressed to the verified

`telephone number indicating the occurrence of the notification

`
`• “receiving, from the user, an acknowledgement of an action

`

`
`7.
`
`First argument: The Petition fails to make out a prima facie case of
`obviousness because it does not show that the “action” limitations are
`taught in the prior art.
`
`The claims recite at least two “action” limitations, in elements 1[d] and 1[f],
`
`as shown below.
`
`Element 1[d]
`
`Element 1[f]
`
`
`
`“maintaining a record of one or more notification events
`associated with actions that require acknowledgement by the
`user.
`
`“receiving, from the user, an acknowledgement of an action
`associated with the established notification event.”
`
`The Petition essentially collapses the recited “action” with a notification-
`
`event itself. It substantively ignores the “associated with [actions]” requirement
`
`and detrimentally focuses only on purported notification events. The Petition
`
`misses the mark by attempting to show acknowledgment of the notification events
`
`themselves rather than of the recited “actions” associated with notification events,
`
`which the claims require. Dr. Nielson confirms that Dr. Shamos similarly
`
`39 Ex. 1001 at 12:64-67 and 14:11-14.
`
`40 Ex. 1001 at 13:1-2 and 14:14-16.
`
`8107716
`
`Page 17
`
`
`
`
`
`repeatedly ignores the “associated with [actions]” requirement of the claims. Ex.
`
`2008 at 9.1-9.4.
`
`As a preliminary matter, the Petition fails to show that Bennett discloses the
`
`notification-event limitations of claim 1. See Section 6. Thus, Bennett does not
`
`disclose maintaining a record of such “actions” associated with “notification
`
`events,” because Bennett does not disclose the recited notification events. An
`
`aspect of the notification-event limitations is that the notification-event limitations
`
`are associated with actions that require acknowledgment (element 1[d]) (which
`
`acknowledgement is received in step 1[f]). The recited notification event and
`
`action are separately recited and different from each other.
`
`Despite its assertion, the Petition does not show that “Campbell teaches
`
`‘notification events associated with actions requiring acknowledgment by the
`
`user.’” Pet. 44. It merely parrots the claim language. At be
