`
`
`THE REPLY DOES NOT CURE THE SHORTCOMINGS OF
`PETITIONER’S ALLEGED MOTIVATION TO COMBINE
`(ELEMENT 1[a])
`
`Petitioner ignores its burden to expressly articulate the motivation
`for modifying Ording’s computer hardware to store “the e-mail
`program of Abiko”
`As explained in the Response (p. 14), the Petition relied upon three distinct
`
`modifications to Ording’s computer followed by two further modifications to the
`
`resulting system. The Reply, for the first time, argues that the alleged motivation
`
`for the first modification (altering Ording’s computer hardware to provide
`
`Abiko’s “wireless capabilities”) thereafter opens the door for Petitioner to freely
`
`select the entirely different second modification (altering Ording’s software
`
`store/execute Abiko’s “e-mail program”) without any articulated motivation for
`
`doing so. Reply, 5 (“which it does not”). This is legal error.
`
`Petitioner ignores the mandatory authority imposing the burden upon
`
`Petitioner to expressly demonstrate motivation/articulated reasoning for distinct
`
`modifications to different parts of a primary reference to achieve different claim
`
`elements. Reply, 4-5. Nothing in the Petition’s analysis of the preamble element
`
`(“wireless capabilities”) necessitated the distinct modification assumed for
`
`Element 1[a] (further modifying Ording’s computer to have a particular species of
`
`email program). Petitioner’s hindsight alone demanded it. Nothing else.
`
`1
`
`
`
`The Federal Circuit’s holding in Polaris Indus., Inc. v. Arctic Cat, Inc.
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`required that a petitioner must prove separate motivations to modify based on the
`
`secondary reference when different claim limitations require different (further)
`
`modifications to the primary reference. 882 F.3d 1056, 1069 (Fed. Cir. 2018).
`
`The Polaris court held that the Board properly assessed a first “motivation” to
`
`modify the primary reference to achieve a particular “four-wheel-drive” claim
`
`element in claim 1. Id. at 1070-71. Critically, for subsequent claim elements that
`
`required distinct modifications to the primary reference (e.g., a specific location of
`
`the “front driveshaft,” and an altered location of a “fuel tank”), the Polaris court
`
`separately analyzed whether the petitioner had proven distinct motivations to
`
`justify those further modifications. Id. at 1066-68. Based on this requirement that
`
`the petitioner must articulate distinct motivations for the distinct modifications to
`
`different parts of a primary reference, the court held there was a sufficient showing
`
`to achieve the “four-wheel drive” modification and the “front drive shaft”
`
`modification, but an insufficiently alleged motivation for the “fuel tank”
`
`modification. Id. at 1068-71.
`
`This understanding of Polaris is no secret to the Board. Previously, the
`
`Board analyzed Polaris and its requirement that a petitioner must separately prove
`
`motivations to combine in these circumstances. Stingray Digital Group Inc. v.
`
`Music Choice, IPR2017-01191, Paper 38 (PTAB Oct. 11, 2018). Facebook now
`
`2
`
`
`
`erroneously contends that, contrary to Polaris and Stingray, if its first motivation
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`(for “wireless capabilities”) is sufficient to justify modifying Ording’s computer
`
`based upon a secondary reference’s teaching for wireless device, then it is no
`
`longer burdened to justify subsequent modifications to Ording’s computer based
`
`upon that secondary reference. The Board must avoid Facebook’s invitation for
`
`error.
`
`The Reply incorrectly asserts that Patent Owner “cites no authority”—oddly
`
`ignoring the Response’s citations to the Polaris, Lee and Cutsforth decisions. In
`
`Cutsforth, the petitioner proposed several distinct modifications to the primary
`
`reference for achieving different claim elements, including a “mounting block
`
`[that] includes a spring” and a “mounting block [that] includes a movable portion.”
`
`Cutsforth v. Motivepower, 636 Fed. Appx. 575, 577-79 (Fed. Cir. 2016). Much
`
`like the Polaris case, the Federal Circuit separately analyzed whether sufficient
`
`motivations to combine were articulated with respect to each proposed
`
`modification to the primary reference, not whether there was one motivation to
`
`combine the references generally. Id.; In re Lee, 277 F.3d 1338, 1343-44 (Fed.
`
`Cir. 2002); In re Kotzab, 217 F.3d 1365, 1371 (Fed. Cir. 2000) (“particular
`
`findings must be made as to the reason the skilled artisan, with no knowledge of
`
`the claimed invention, would have selected these components for combination in
`
`the manner claimed” (emphasis added)).
`
`3
`
`
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`Finally, the Reply’s assumed starting point—for the POSITA being “already
`
`armed with Ording and Abiko” (p. 5)—also highlights another error rooted in
`
`Petitioner’s gravity toward hindsight. Not only is such an argument plainly
`
`contrary to the tact taken by the Federal Circuit in Polaris, Cutsforth, and Kotzab
`
`(cited above), but this is the exact error in PersonalWeb that led to a reversal of a
`
`PTAB final written decision. 848 F.3d 987, 993-94 (Fed. Cir. 2017) (“But that
`
`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.” (emphasis added)); Response, 21-22 (citing PersonalWeb).
`
`Simply put, a mere showing of a motivation to provide “wireless
`
`capabilities” in the analysis of the preamble (Pet., 31) does not unburden Petitioner
`
`from articulating a motivation for distinct (further) modifications to Ording’s
`
`computer, such as storing/executing Abiko’s particular species of “e-mail
`
`program.” (Pet., 33-34). It was a fatal error for the Petition to assume otherwise,
`
`and the Reply cannot cure it at this late stage. See Response, 16 (“subsequently
`
`backfilling”).
`
`
`
`The Reply belatedly attempts to recast its original purported
`motivations for incorporating “wireless capability” (Preamble) or
`modifying Ording’s “icon” display (Element 1[c]) into a distinct
`showing for modifying Ording’s computer to store/execute the “e-
`mail program of Abiko” (Element 1[a]).
`A straightforward review of pages 33-35 of the Petition (analysis of Element
`
`4
`
`
`
`1[a]) demonstrates the lack of any articulated reasoning as to why a POSITA
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`would have been motivated to modify Ording’s computer to store/execute Abiko’s
`
`particular species of “e-mail program.” The Reply does not dispute this
`
`deficiency, acknowledging that “those pages were devoted to simply laying out
`
`and explaining the combination itself.” Reply, 3, fn. 2. Of course, the Petition
`
`then proceeds to Element 1[b] where the result of this modification is now
`
`assumed—Ording’s computer executing Abiko’s particular species of email
`
`software with the “sender table.” Pet., 35-36. This was not enough. Response, 19
`
`(“by the time the Petition reaches the end of its analysis of Elements 1[a]-1[b]”).
`
`Now, the Reply belatedly attempts to recast “other disclosures in the
`
`Petition” as providing motivation for the modification of Element 1[a]. Reply, 3.
`
`Critically, however, those “other disclosures” are directed to other distinct
`
`modifications (necessary to Petitioner’s alleged modifications in the preamble and
`
`1[c]), and assume Ording’s computer has already been modified to incorporate
`
`Abiko’s software. Federal Circuit precedent shows why such newly shifted
`
`theories at this late stage should be disregarded. Henny Penny Corp. v. Frymaster
`
`LLC, 938 F.3d 1324, 1330-1331 (Fed. Cir. 2019) (“may not raise in reply ‘an
`
`entirely new rationale’”); Intelligent Bio-Systems, Inc. v. Illumina Cambridge, Ltd.,
`
`821 F.3d 1359, 1369 (Fed. Cir. 2016) (“utmost importance”); In re Magnum Oil
`
`Tools Int’l, 829 F.3d 1364, 1378-81 (Fed. Cir. 2016) (“could have been included in
`
`5
`
`
`
`a properly drafted petition, but was not”).
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`First, the Reply argues that the first motivation to provide Ording with
`
`“wireless communication capabilities” (Pet., 31 (analysis of Preamble)) is “not
`
`only relevant to” modifying Ording’s computer to provide wireless capabilities, but
`
`also to modifying Ording’s computer to incorporate Abiko’s email program.
`
`Reply, 3. The Petition, however, never made this connection. Henny Penny, 938
`
`F.3d at 1330-1331. This part of the Petition explains (and emphasizes in
`
`Petitioner’s italics) that the proposed combination modifies Ording’s computer to
`
`provide “wireless communication capabilities.” Pet., 31. It never proposes
`
`modifying Ording’s computer to store/execute the particular species of Abiko’s
`
`email program, and never offers any alleged motivation for doing so. Pet., 31-33.
`
`Moreover, Petitioner’s assertion of “expectation of success” is directed to this
`
`“wireless” capability, not storing/executing Abiko’s email software, further
`
`highlighting the Petition’s exclusive focus on “wireless communication
`
`capabilities” in the analysis of the preamble. Pet., 33.
`
`In this same vein of relying upon the Petition’s analysis of the preamble, the
`
`Reply also cites to page 32 of the Petition for the contention that the wireless
`
`capabilities provided “a convenience that was ‘particularly advantageous in the
`
`context of electronic messaging, as it allows users to send and receive messages on
`
`the go, as Abiko expressly confirms. (Petition at 32).’” But page 32 of the Petition
`
`6
`
`
`
`plainly relates to modifying Ording’s computer hardware to be a “wireless
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`communication device,” not an articulated reason for storing/executing a particular
`
`species of email program on Ording’s computer. At best, it is directed to types of
`
`suitable computing devices—namely, “wireless” devices that allowed users to send
`
`and receive messages “on the go.” Pet., 32 (“pertinent to identifying the types of
`
`computing devices that can be used in Ording” (emphasis added)). Indeed, page
`
`32 explains why “the user interface techniques in Ording,” not in Abiko, would be
`
`used in the resulting system. Id. (emphasis added).
`
`Second, the Reply argues for the first time that the modification proposed in
`
`the Petition’s analysis of Element 1[a] would have been motivated by Abiko’s
`
`ability to automatically display messages “by sender.” Reply, 8-9; see also 5
`
`(“based on their senders”). The Reply alleges that the motivation can be found
`
`under the “Rationale and Motivation to Combine” headings of the Petition, but
`
`review of each instance of this heading confirms the Petition’s analysis was
`
`directed to modifications of Ording’s icon display (and then further proposed
`
`alterations to Abiko’s sender table in the resulting system), not the initial
`
`modification of Ording’s computer to store/execute the particular species of email
`
`program of Abiko. Pet., 43-49. Indeed, the Petition states these “Motivation to
`
`Combine” sections are expressly tethered to “this claim limitation” in Element
`
`1[c], not Element 1[a]. Pet., 45 (“in connection with this claim limitation”
`
`7
`
`
`
`(emphasis added)); 43 (“With respect to this limitation” (emphasis added)). The
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`Reply cannot rewrite these pages of the Petition.
`
`Likewise, before the Reply, even Petitioner’s declarant did not consider the
`
`purported “sender-centric” motivation for the modification proposed in Element
`
`1[c] to be tethered to the analysis of Element 1[a]. When asked about Element 1[a]
`
`before the Reply, Dr. Chatterjee indicated Element 1[a] was addressed in the
`
`section with the Element 1[a] heading, and in the preceding “analysis related to the
`
`preamble as well as the summary of the prior art,” never referring to subsequent
`
`analysis related to the claim limitation in Element 1[c]. EX2017, 31:3-10; see also
`
`30:21-31:2.
`
` Even if the purported motivation to “automatically display
`messages by sender” was tethered to the Petition’s modification
`proposed in Element 1[a] (which it was not), it fails to satisfy
`Petitioner’s burden
`The Response noted the Petition’s original reliance on Ording’s mention of
`
`the genus of “email applications,” but the Petition’s analysis of Element 1[a] (Pet.,
`
`33-34) never provided a specific reasoning why a POSITA would have selected
`
`Abiko’s particular species from the mere mention of a genus. Response, 18. The
`
`Reply’s new theory suffers the same shortcoming. It describes a generic benefit
`
`provided by a wide swath of email applications at the time, not a specific reason to
`
`select Abiko’s particular species from the genus. The only documentary evidence
`
`8
`
`
`
`of such common email applications used on Ording’s Apple Macintosh computer
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`at the time—the Apple Mail1 program—demonstrates exactly why these
`
`conventional email applications already achieved a solution to “automatically
`
`display messages by sender.” For example, Petitioner and its declarant never
`
`dispute Dr. Surati’s testimony that “the POSITA in 2003 already knew of the
`
`‘Apple Mail’ solution prevalent” on such Apple Macintosh computer. EX2013,
`
`¶47. Worse yet, Petitioner never addresses the fact that Apple Mail, much like
`
`others in Ording’s genus of “email applications” used at the time (and now),
`
`
`1 Petitioner demands consideration of the prevalence of Apple Macintosh
`
`computers using Ording’s userbar “for almost two decades” (Pet., 14), but then
`
`inconsistently dismisses the ubiquitous Apple Mail software bundled with those
`
`same computers as “irrelevant” (Reply, 6). This ignores the law and the burden
`
`imposed on Petitioner. Evidence of the predominant email program on Ording’s
`
`Apple Macintosh computer must be considered here just as a POSITA would have
`
`done so back in 2003. Arctic Cat Inc. v. Bombardier Recreational Prods. Inc., 876
`
`F.3d 1350, 1363 (Fed. Cir. 2017) (“Evidence suggesting reasons to combine cannot
`
`be viewed in a vacuum apart from evidence suggesting reasons not to combine”);
`
`Infra, Section II.B.
`
`9
`
`
`
`includes “buttons” that automatically sort on selected parameters, including by
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`sender (i.e. “From”):
`
`
`EX2014, 21 (color added); see also EX1110, 45 (showing inbox sort “buttons”).
`
`Petition’s declarant confirmed Apple Mail’s capability to automatically sort using
`
`column header “buttons.” EX2018, 20:18-21:5.
`
`Petitioner identifies “numerous other email programs” in use in 2003, yet
`
`does not address the functionality of these programs, and does not allege that any
`
`of these programs lacked the capability to automatically display messages by
`
`sender. In fact, Petitioner’s declarant indicated these traditional email programs,
`
`such as Microsoft Exchange (depicted at EX2013, 45), included this standard
`
`inbox sort-by-sender capability. EX2018, 18:13-20 (“click on that, the column
`
`header and it would sort based on the received time stamp.”); 20:18-22:4 (“it may
`
`have allowed to press the column title or some other means to sort the messages
`
`10
`
`
`
`below that.”); 23:9-21.
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`Ultimately, the uncontroverted documentary evidence confirms that
`
`Petitioner’s belated motivation relates to a generic feature—“automatically display
`
`messages by sender”—which was a benefit of Ording’s genus of “email
`
`applications,” not a specific reason to select Abiko’s particular species from that
`
`genus back in 2003. Petitioner’s newly concocted motivation is thus “not enough”
`
`because it fails to provide a reason for a POSITA to select Abiko’s particular
`
`species from the genus. Knauf Insulation, Inc. v. Rockwool Int’l A/S, 788 Fed.
`
`Appx. 728, 733 (“It is not enough, even after KSR, to support a determination of
`
`obviousness that a reference includes a broad generic disclosure and a common
`
`utility to that in the claims and other prior art references—there must be some
`
`reason to select a species from the genus.” (emphasis added)).
`
`Moreover, Petitioner’s assertion that “Patent Owner does not contest the
`
`benefits of this feature” (Reply, 6 and 9) attempts to impermissibly shift its burden
`
`to Patent Owner—an erroneous theory the Board cannot adopt. Magnum Oil, 829
`
`F.3d at 1378 (“improperly shifted the burden to [Patent Owner] to disprove
`
`obviousness.”). Petitioner had the burden of establishing a reason why a POSITA,
`
`starting from Ording’s computer and without hindsight, would have been
`
`motivated to make the unique sequence of modifications demanded by the Petition.
`
`Id.
`
`11
`
`
`
`The Petition failed. The original obviousness theory of Element 1[a] was
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`not enough and supported only by an insufficient “ipse dixit declaration.” TQ
`
`Delta, LLC v. Cisco Sys., 942 F.3d 1352, 1362-63 (Fed. Cir. 2019); Response, 22.
`
` THE REPLY DOES NOT CURE THE PETITION’S FAILURE TO
`SATISFY ITS BURDEN OF DEMONSTRATING WHY A POSITA
`WOULD HAVE MODIFIED ORDING’S ICON (ELEMENT 1[c])
` Dr. Surati’s testimony regarding the significance of numbers in
`the first column of Abiko’s FIG. 8 is uncontroverted.
`There is no dispute that the rows of “dots” in Abiko’s FIG. 8 signify the
`
`presence of additional rows of data in the list. Reply, 10. Such additional rows
`
`were not shown on Abiko’s suggested initial screen, and instead required the user
`
`to manually scroll down to see the later information. Id.; see also EX2017, 76:18-
`
`78:4. Critically, the Reply likewise never actually disputes Dr. Surati’s testimony
`
`that these teachings suggest the unimportance of Abiko’s final row. EX2013,
`
`¶¶53-55 (“the final row of Abiko’s sender menu was buried at the end of the
`
`listing”).2 Yet, despite Abiko’s indication of relative unimportance of the final row
`
`compared to the preeminence of initial rows in the sender menu, the Petition
`
`
`2 The Reply does not dispute Dr. Surati’s testimony that [0099] of Abiko is
`
`contrary to Petitioner’s assertion that a number of unread messages might be more
`
`valuable than a number of all messages. EX2013, ¶56.
`
`12
`
`
`
`assumes that a POSITA would have plucked only the last row number from Abiko
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`for the pinnacle importance of being superimposed as a notification on Ording’s
`
`userbar icon. Id. Such an assumption is classic hindsight guided by the map of
`
`claim 1, which is highlighted by the Petition’s present-day speculation being
`
`copied verbatim into the paragraphs of an “ipse dixit declaration.” Response, 27-
`
`28 (citing TQ Delta, 942 F.3d at 1362-63).
`
`Petitioner assumes that “in the context of Abiko and its overriding purpose
`
`of organizing email by sender, the total message count (e.g., ‘37’) would have been
`
`less significant to a user of such the Abiko system.” Reply, 12. But Petitioner here
`
`again fails to address that Abiko belies this assumption. Abiko itself displays the
`
`total message counts for each sender and elevates the row number with the highest
`
`total message count. According to Abiko, the final number for Abiko’s last row is
`
`not worthy of initially displaying to the user, and may never be displayed without
`
`additional manual scrolling by the user. Patent Owner fails to square the relative
`
`unimportance of a number in the last sender row of Abiko, with Petitioner’s
`
`assertion that “the number of senders who sent unread messages might be more
`
`valuable to certain users than a simple count of new messages.” Reply, 12.3
`
`
`3 Petitioner fails to reconcile its purported count of “four” senders/“37” messages
`
`13
`
`
`
`Trial was instituted in part based on a finding that “Patent Owner’s
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`arguments thus, at this juncture, do not address the significance of the number to a
`
`person of ordinary skill in the art and how the tracking mechanism would report
`
`the total number of senders in the sender table.” Decision, 22. Both of these issues
`
`have been addressed in detail by Dr. Surati, and the level of insignificance of the
`
`final row number is not disputed. See, e.g. EX2013, ¶55; Reply, 10; EX2017,
`
`76:18-78:4.
`
`
`
`Petitioner ignores “tradeoffs” without properly analyzing the
`prior art’s stated preferences and evidence of reasons not to
`modify Ording’s numeral.
`The Reply notes the “existence of such tradeoffs” without fulfilling
`
`Petitioner’s burden of actually weighing those specific “tradeoffs.” (Reply, 10.
`
`Petitioner’s theory that “tradeoffs” may not prevent a finding of obviousness is not
`
`license to entirely ignore its burden to provide evidence weighing those tradeoffs.

`Winner Int’l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 (Fed. Cir. 2000)
`
`(tradeoffs “should be weighed against one another”); Arctic Cat, 876 F.3d at 1363
`
`(“Evidence suggesting reasons to combine cannot be viewed in a vacuum apart
`
`from evidence suggesting reasons not to combine”). Petitioner impermissibly flips
`
`

`
`additional numbered items in the list.”

`

`the burden, attempting to place upon Patent Owner the burden of demonstrating
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`that the “tradeoffs” weigh against the proposed combination. Reply, 13; 16; 17.
`
`The Board should avoid this error. Magnum Oil, 829 F.3d at 1378.
`
`With respect to Dvorak, Petitioner assumes Dvorak’s complaints about
`
`email would be resolved by Petitioner’s hindsight proposal of presenting a numeric
`
`character identifying the number of senders of unread messages (Reply, 12-13),
`
`without citing anything in Dvorak describing use of a “number of senders” or
`
`otherwise suggesting any solution at all. Worse, the Reply dismisses Dvorak’s
`
`complaints that do not support Petitioner’s modification, such as “mail storms,” as
`
`merely confirming “the existence of tradeoffs” for potential approaches. Reply,
`
`13. The Petition, however, never actually weighed these tradeoffs to address why
`
`they would have led to Petitioner’s sequence of modifications. Petitioner failed to
`
`meet this burden.
`
`Likewise, Petitioner attempts to explain away its improper focus on what
`
`“might” or “could” be done (Response, 25-26), without providing the proper
`
`analysis of whether a POSITA “would have been” motivated to modify Ording in
`
`the manner proposed in view of the tradeoffs. Reply, 9-10. Without identifying
`
`what “category of users” allegedly “might” have preferred Petitioner’s unique
`
`sequence of modifications to Ording’s computer back in 2003, Petitioner’s
`
`assertion reduces to a non-sequitur. Petitioner takes no position as to whether such
`
`15
`
`
`
`users existed or would have been motivated to make the proposed modification,
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`only that this “might” be the case.4
`
`Lacking any analysis of the “tradeoffs” a POSITA would have faced,
`
`Petitioner’s analysis reduces to bare assertions that the proposed modifications
`
`were feasible—mere combinability. Response, 25-29. This is insufficient to
`
`demonstrate motivations for the unique sequence of modifications to Ording’s
`
`original computer. Winner, 202 F.3d at 1349 (Fed. Cir. 2000) (“Trade-offs often
`
`concern what is feasible, not what is, on balance, desirable. Motivation to combine
`
`requires the latter.”).
`
` THE REPLY DOES NOT CURE THE PETITION’S FAILURE TO
`DEMONSTRATE WHY A POSITA WOULD HAVE FURTHER
`MODIFIED ABIKO IN THE PROPOSED MANNER (ELEMENT 1[c])
` The Reply fails to cure errors in the Petition’s further
`modifications to Abiko’s e-mail program based on Crumlish’s
`description of “Pegasus mail” (Element 1[c])
`Petitioner’s dismissal of Crumlish’s teachings as “mere subjective opinions”
`
`to be ignored introduces legal error. Reply, 15. The Federal Circuit has made
`
`clear that a cited reference’s “statements regarding preferences are relevant to a

`
`shortcomings of Petitioner’s “obvious to try” theory, essentially waiving its

`position.

`
`Instead of properly addressing Crumlish’s stated preferences, Petitioner
`
`attempts to dismiss them as “having nothing to do with the proposed combination.”
`
`Reply, 14; 15 (“merely identifying the author’s personal preferences”). Petitioner
`
`speculates that Crumlish’s teachings for managing mailboxes “could,” contrary to
`
`Crumlish’s express statements, be followed “after an email message has been read
`
`and automatically moved to the Main mail folder.” Reply, 15. Petitioner’s
`
`configuration, however, highlights the very problem that Crumlish was concerned
`
`with—forgetting about a message before the user “replied to it.” Response, 36-38.
`
`According to Crumlish’s concern, a user in the habit of looking at the default
`
`folder (“New Mail folder”) would more easily forget about the read-but-never-
`
`replied-to messages because they were automatically moved out of view. EX2013,
`
`17
`
`
`
`¶¶61-62.5 Crumlish identified this problem and explicitly suggested it should be
`
`Case IPR2019-00925
`Attorney Docket No: 21828-0048IP1
`
`
`avoided. Petitioner ignored it, and thus ignored Petitioner’s burden.
`
`The Reply also does not cure the Petition’s failure to address Crumlish’s
`
`solutions of indicating new mail, which are not taught to suffer from the problems
`
`of Pegasus mail. The Reply merely asserts that such solutions do “not teach away”
`
`from the “separate folder technique of Pegasus Mail.” Reply, 16. But even if
`
`discussion of these solutions did not rise to explicitly “teaching away,” Petitioner
`
`still had a burden to address the common sol
