`
`I.
`
`BACKGROUND
`I, William C. Messner, make this Declaration in connection with the Patent
`
`Owner’s Motions to Amend U.S. Patent 8,769,747 (the ’747 Patent) and U.S. Patent
`
`9,737,154 (the ’154 Patent). Specifically, this Declaration is submitted with the
`
`Patent Owner’s Revised Motion to Amend in Case No. IPR2019-00497 involving
`
`the ’747 Patent and the Reply in Support of Patent Owner’s Motion to Amend in
`
`Case No. IPR2019-00500 involving the ’154 Patent. To that end, I hereby declare as
`
`follows:
`
`1.
`
`I am over the age of 21 years and am fully competent to make this
`
`Declaration. I make the following statements based on personal knowledge and, if
`
`called to testify to them, could and would do so. I have been retained on behalf of
`
`Sleep Number Corporation to opine on certain issues raised in the above-identified
`
`proceedings concerning the ’747 Patent and the ’154 Patent. My fee is not contingent
`
`on the outcome of any matter or on any of the technical positions that I explain in
`
`this Declaration. I have no financial interest in Sleep Number Corporation, nor the
`
`’747 and ’154 Patents.
`
`2.
`
`This Declaration is intended to be read with my prior declarations in
`
`support of the Patent Owner’s Responses (Exs. 2001 and 2025 in IPR2019-00497
`
`and Exs. 2001 and 2025 in IPR2019-00500; “Companion Declarations”). In my
`
`Companion Declarations, I address many topics, including my background and
`
`1
`
`Sleep Number Corp.
`EXHIBIT 2079
`IPR2019-00500
`Page 3
`
`

`

`
`
`qualifications, the level of skill in art, a background on the technology of the patents
`
`at issue, claim construction, and many other topics. I maintain all of the opinions and
`
`explanations expressed in my Companion Declarations, and all that I testified to in
`
`those documents applies equally here.
`
`3.
`
`In preparing this declaration, and in addition to the information I
`
`reviewed when preparing my Companion Declarations, (see, e.g., Ex. 2025 at ¶¶ 15-
`
`16), I have reviewed Patent Owner’s Motion to Amend in IPR2019-00500 and
`
`Patent Owner’s Revised Motion to Amend in IPR2019-00497. I have also reviewed
`
`Petitioner’s Oppositions to Patent Owner’s Motions to Amend in both IPR2019-
`
`00497 and -00500 (“Opp.”) and the supporting evidence submitted therewith as well
`
`as the transcript from the deposition of ANM’s expert, Dr. Phinney, from February
`
`20, 2020 (Ex. 2080). I have also reviewed the Board’s preliminary guidance in both
`
`IPR2019-00497 and -00500.
`
`II. THE UNDERSTANDINGS APPLIED TO MY ANALYSIS
`4.
`Based upon my review of the Petitions and Oppositions to Patent
`
`Owner’s Motions to Amend that were filed by Petitioner, it is my understanding that
`
`at least Gifft, Mittal, and Pillsbury are used to argue the proposed substitute claims
`
`are unpatentable. Specifically, I understand that Petitioner relies upon at least Gifft,
`
`Mittal, and Pillsbury (requiring Ebel for most of its combination) to argue the
`
`proposed substitute claims in IPR2019-00500 are unpatentable. I further understand
`
`2
`
`Sleep Number Corp.
`EXHIBIT 2079
`IPR2019-00500
`Page 4
`
`

`

`
`
`that because Patent Owner is filing a Revised Motion to Amend in IPR2019-00497,
`
`Petitioner is not confined to using these same references in its Opposition to Patent
`
`Owner’s Revised Motion to Amend. However, given Dr. Phinney’s admission that
`
`other than Ebel’s purported disclosures he is unaware of any art that discloses use of
`
`a multiplicative offset, I expect Petitioner will continue to use the same combinations
`
`in its Opposition to Patent Owner’s Revised Motion to Amend.
`
`5.
`
`In addition to the understandings outlined in my Companion
`
`Declarations (¶¶17-26 of Ex. 2001 in IPR2019-00497 and IPR2019-00500), Counsel
`
`has informed me that claims must be enabled by the original disclosure of the patent.
`
`For the claims to be enabled, the information contained in the disclosure must be
`
`sufficient to inform those skilled in the relevant art how to make and use the claimed
`
`invention without undue experimentation. I do not offer any opinions in this
`
`Declaration concerning enablement, and merely note my understanding of the
`
`concept to support the following discussion.
`
`6.
`
`Counsel has informed me that the original disclosure must contain a
`
`written description of the claimed invention. The written description requirement is
`
`separate and distinct from the enablement requirement I discussed above. To satisfy
`
`the written description requirement, the original disclosure must describe (in writing
`
`or drawings) the claimed invention in sufficient detail that one skilled in the art can
`
`reasonably conclude the inventor had possession of the claimed invention. In other
`
`3
`
`Sleep Number Corp.
`EXHIBIT 2079
`IPR2019-00500
`Page 5
`
`

`

`
`
`words, the question is whether one of skill can discern from the original disclosure
`
`that the named inventor actually invented the subject matter later claimed.
`
`III. THE CHALLENGED PATENTS
`7.
`The ’154 Patent is a continuation of the ’747 Patent. These two patents
`
`share an identical specification. The shared specification is gleaned from a priority
`
`international patent application—PCT/US2008/059409 (Ex. 2081; the ’409
`
`Application)—filed April 4, 2008. The analysis in my Companion Declarations
`
`references the ’747 Patent and the ’154 Patent, respectively. On the other hand, my
`
`written description analysis of this declaration will often refer to the ’409
`
`Application with an understanding that the international application represents the
`
`original disclosure of both patents.
`
`IV. THE AMENDED CLAIMS OF THE CHALLENGED PATENTS
`8.
`As noted in my Companion Declarations, Petitioner has challenged the
`
`validity of many claims. The following claims of the ’747 Patent and the ’154 Patent,
`
`in IPR2019-00497 and IPR2018-00500 are relevant to this analysis:
`
` ’747 Patent: claims 1-6 and 10-16
`
` ’154 Patent: claims 1, 3-5, 7-10, 12-22

`V. WRITTEN DESCRIPTION SUPPORT OF THE SUBSTITUTE
`CLAIMS
`10. Table 2A below and my subsequent discussion of certain claim
`
`elements demonstrate that substitute claims 20-32 at issue in IPR2019-00497
`
`(the ’747 Patent proceeding) are fully supported by the ’409 Application’s

`
`
`disclosure. 1 By “fully supported,” I mean that I have considered each of the
`
`substitute claims as a whole, and I have determined that the disclosure of the ’409
`
`Application makes clear the inventors possessed (i.e., invented) the subject matter
`
`recited in the substitute claims. The analysis and citations (which are meant to be
`
`exemplary, not necessarily exhaustive) in Table 2A indicate where the ’409
`
`Application addresses the features of each claim element.
`
`Claim Element
`
`20.P - A method for adjusting
`pressure within an air bed

`
`26.P - A method for adjusting
`pressure within an air bed

`would understand there was support for an
`air bed pressure adjustment system and

`
`incorporated by reference; and I have done so.

`My analysis:
`Based on the citations to the ’409
`Application provided below, a POSITA
`would understand there was support for an
`(i) air bed including an air chamber and a
`pump housing; and (ii) the
`step/functionality of selecting a desired
`setpoint for the air chamber, e.g., from an
`input device like a remote control.
`Citations to the ’172 Patent further support
`the substitution of “pump housing” for
`“valve enclosure” and “air chamber” for
`“air bladder.” A POSITA would have
`understood that these are synonymous
`terms. The substitution does not change the
`meaning or scope of the claims.2
`
`20.1-20.2 - providing or receiving
`an air bed, the air bed including an
`air bladder and a pump having a
`valve enclosure; selecting a desired
`pressure setpoint for the air bladder;
`
`26.1-26.2 - providing or receiving
`an air bed, the air bed including
`plurality of air bladders and a pump
`having a valve enclosure; selecting
`a desired pressure setpoint for at
`least one of the plurality of air
`bladders;
`
`32.1-32.3 –
`an air bladder;
`
`2 I understand the Motion to Amend has universally implemented the replacement
`
`of these synonymous terms throughout the proposed amended claims based upon
`
`citations to the ’172 Patent. Rather than repeat the citations to the ’172 Patent for

`adjustment factor that was used to calculate
`a pressure target for deflation by
`multiplying/dividing the multiplicative
`pressure adjustment factor and the desired
`pressure setpoint; and (3) that an inflate
`pressure target would be used when the
`initial pressure within the valve enclosure
`is less than the desired pressure setpoint
`and that a deflate pressure target would be
`used when the initial pressure within the
`valve enclosure is greater than the desired
`pressure setpoint.
