`
`I, Thomas F. La Porta, declare as follows:
`
`I have personal knowledge of the facts stated in this declaration, and
`
`could and would testify to these facts under oath if called upon to do so.
`
`I.
`
`INTRODUCTION AND QUALIFICATIONS
`A. Engagement Overview
`3.
`I have been retained by counsel by Cisco Systems, Inc. (“Petitioner”)
`
`in this case as an expert in the relevant art. I previously provided a declaration in
`
`related cases (2016-01259, -01261, -0162, 0163) in support of the Petition setting
`
`forth my opinions regarding the state of the art and invalidity of the challenged
`
`claims. I am being compensated for my work at the rate of $550 per hour. No part
`
`of my compensation is contingent upon the outcome of this petition.
`
`4.
`
`I was asked to study the Patent Owner’s April 3, 2017 Contingent
`
`Motion to Amend in Inter Partes Review of U.S. Patent No. 8,457,113 (“the ‘113
`
`patent”), and its exhibits including the declaration of Regis J. “Bud” Bates dated
`
`April 2, 2017 (Ex. 2040), and to render opinions based on the testimony of Mr.
`
`Bates contained in his declaration (Id.) and in the transcripts of Mr. Bates’
`
`deposition taken on May 8-9, 2017 (Ex. 1148; Ex. 1149).
`
`5.
`
`After studying the Response, its exhibits including the declaration of
`
`Mr. Bates (Ex. 2040), the transcripts of his deposition (Ex. 2058; Ex. 2059, the
`
`
`
`
`

`
`

`

`
`
`‘113 patent (Ex. 1101), its file history (Ex. 1108) and the file history of related
`
`U.S. Patent No. 7,764,777 (“the ‘777 patent”) (Ex. 1108), the prior art, and
`
`considering the subject matter of the claims of the ‘113 patent in light of the state
`
`of technical advancement in the area of telephony in circuit-switched and packet-
`
`switched networks in May 2000, I reached the conclusions discussed herein.
`
`6.
`
`This declaration, and the conclusions and opinions herein, provide
`
`support for the Opposition to Patent Owner’s Contingent Motion to Amend filed
`
`by Petitioners in this case. I have reviewed the Opposition in its entirety as well as
`
`its corresponding exhibits.

`
`Summary of Opinions
`
`As set forth in my June 24, 2016 Declaration in the related cases
`
`(2016-01259, -01261, -0162, 0163), it is my opinion that claims 1, 2, 8, 11, 15-19,
`
`94, 95, 102, 109-113, 128, 163, 164, 166-168, 175, 179, 180, 181 of the ‘113
`
`patent are obvious over Archer in view of the knowledge of a person of ordinary
`
`skill in the art (“POSA”). As also set forth in my June 24, 2016 Declaration, it is
`
`also my opinion that claims 1, 2, 8, 11, 15-19, 94, 95, 102, 109-113, 128, and 168
`
`of the ‘113 patent are obvious over Archer in view of Chang and the knowledge of
`
`a POSA. My opinions are unchanged.
`
`8.
`
`As set forth herein, it is my opinion that Patent Owner has not made
`
`
`
`
`
`2
`
`Cisco Systems, Inc., EX 1157 Page 5
`
`

`

`
`
`the required showing that Substitute Claim 184 is patentable over the cited art in
`
`the Petition.
`
`9.
`
`As set forth herein, it is my opinion that Patent Owner cannot show
`
`that Substitute Claim 184 is patentable over newly cited U.S. Patent No. 6,442,169
`
`to Lewis (“Lewis”) (Ex. 1146) and U.S. Patent No. 6,333,931 to LaPier (“LaPier”)
`
`(Ex. 1147).
`
`C. Materials Considered
`10. My analysis is based on my education and experience as set out in my
`
`in my curriculum vitae (Ex. 1158), including the documents I have read and
`
`authored and systems I have developed and used since then.
`
`11.
`
`I have reviewed the following in forming my opinions:

`
`II. LEGAL PRINCIPLES USED IN THE ANALYSIS
`12.
`In addition to the legal principles set forth in my June 24, 2016
`
`Declaration in this case related cases (2016-01259, -01261, -0162, 0163) (Ex.
`4
`
`
`
`
`
`Cisco Systems, Inc., EX 1157 Page 7
`
`

`

`
`
`1156, ¶¶25-38), attorneys for the Petitioners explained additional legal principles
`
`to me that I have relied upon in forming my opinions set forth in this declaration.
`
`A. Legal Standards for Anticipation and Obviousness
`13.
`I have been provided the following instruction from the Model Patent
`
`Jury Instructions for the Northern District of California (July 16, 2014) for
`
`anticipation, and the Federal Circuit Bar Association Model Instructions regarding
`
`obviousness, which are reproduced in part below. I apply this understanding in my
`
`analysis, with the caveat that I have been informed that the Patent Office will find
`
`a patent claim invalid in Inter Partes Review if it concludes that it is more likely
`
`than not that the claim is invalid (i.e., a preponderance-of-the- evidence standard),
`
`which is a lower burden of proof than the “clear-and- convincing” standard that is
`
`applied in United States district court (and described in the jury instruction below):
`
`4.3a1 ANTICIPATION
`
`A patent claim is invalid if the claimed invention is not new. For the
`claim to be invalid because it is not new, all of its requirements must
`have existed in a single device or method that predates the claimed
`invention, or must have been described in a single previous
`publication or patent that predates the claimed invention. In patent
`law, these previous devices, methods, publications or patents are
`called “prior art references.” If a patent claim is not new we say it is
`“anticipated” by a prior art reference.
`5
`
`
`
`
`
`Cisco Systems, Inc., EX 1157 Page 8
`
`

`

`The description in the written reference does not have to be in the
`same words as the claim, but all of the requirements of the claim must
`be there, either stated or necessarily implied, so that someone of
`ordinary skill in the field of [identify field] looking at that one
`reference would be able to make and use the claimed invention.
`
`Here is a list of the ways that [alleged infringer] can show that a
`patent claim was not new [use those that apply to this case]:
`
`[– if the claimed invention was already publicly known or publicly
`used by others in the United States before [insert date of conception
`unless at issue];]
`
`[– if the claimed invention was already patented or described in a
`printed publication anywhere in the world before [insert date of
`conception unless at issue]. [A reference is a “printed publication” if it
`is accessible to those interested in the field, even if it is difficult to
`find.];]
`
`[– if the claimed invention was already made by someone else in the
`United States before [insert date of conception unless in issue], if that
`other person had not abandoned the invention or kept it secret;]
`
`[– if the claimed invention was already described in another issued
`
`U.S. patent or published U.S. patent application that was based on a
`patent application filed before [insert date of the patent holder’s
`application filing date] [or] [insert date of conception unless at issue];]
`
`6
`
`
`
`
`
`
`
`Cisco Systems, Inc., EX 1157 Page 9
`
`

`

`
`
`[– if [named inventor] did not invent the claimed invention but instead
`learned of the claimed invention from someone else;]
`
`[– if the [patent holder] and [alleged infringer] dispute who is a first
`inventor, the person who first conceived of the claimed invention and
`first reduced it to practice is the first inventor. If one person conceived
`of the claimed invention first, but reduced to practice second, that
`person is the first inventor only if that person (a) began to reduce the
`claimed invention to practice before the other party conceived of it
`and (b) continued to work diligently to reduce it to practice. [A
`claimed invention is “reduced to practice” when it has been tested
`sufficiently to show that it will work for its intended purpose or when
`it is fully described in a patent application filed with the PTO].]
`
`[Since it is in dispute, you must determine a date of conception for the
`[claimed invention] [and/or] [prior invention]. Conception is the
`mental part of an inventive act and is proven when the invention is
`shown in its complete form by drawings, disclosure to another or other
`forms of evidence presented at trial.]
`
`Model Patent Jury Instructions for the Northern District of California at 30-31, §
`
`4.3a1 (July 16, 2015).
`
`4.3a2 STATUTORY BARS
`
`A patent claim is invalid if the patent application was not filed within
`the time required by law. This is called a “statutory bar.” For a patent
`claim to be invalid by a statutory bar, all of its requirements must have
`
`7
`
`
`
`
`
`Cisco Systems, Inc., EX 1157 Page 10
`
`

`

`been present in one prior art reference dated more than one year
`before the patent application was filed. Here is a list of ways [alleged
`infringer] can show that the patent application was not timely filed:
`[choose those that apply]
`
`[– if the claimed invention was already patented or described in a
`printed publication anywhere in the world before [insert date that is
`one year before effective filing date of patent application]. [A
`reference is a “printed publication” if it is accessible to
`those
`interested in the field, even if it is difficult to find.];]
`
`[– if the claimed invention was already being openly used in the
`United States before [insert date that is one year before application
`filing date] and that use was not primarily an experimental use (a)
`controlled by the inventor, and (b) to test whether the invention
`worked for its intended purpose;]
`
`[– if a device or method using the claimed invention was sold or
`offered for sale in the United States, and that claimed invention was
`ready for patenting, before [insert date that is one year before
`application filing date]. [The claimed invention is not being [sold] [or]
`[offered for sale] if the [patent holder] shows that the [sale] [or] [offer
`for sale] was primarily experimental.] [The claimed invention is ready
`for patenting if it was actually built, or if the inventor had prepared
`
`drawings or other descriptions of the claimed invention that were
`sufficiently detailed to enable a person of ordinary skill in the field to
`make and use the invention based on them.];]
`8
`
`
`
`
`
`
`
`Cisco Systems, Inc., EX 1157 Page 11
`
`

`

`
`
`[– if the [patent holder] had already obtained a patent on the claimed
`invention in a foreign country before filing the original U.S.
`application, and the foreign application was filed at least one year
`before the U.S. application.]
`
`For a claim to be invalid because of a statutory bar, all of the claimed
`requirements must have been either (1) disclosed in a single prior art
`reference, (2) implicitly disclosed in a reference to one skilled in the
`field, or (3) must have been present in the reference, whether or not
`that was understood at the time. The disclosure in a reference does not
`have to be in the same words as the claim, but all the requirements
`must be there, either described in enough detail or necessarily implied,
`to enable someone of ordinary skill in the field of [identify field]
`looking at the reference to make and use the claimed invention.
`
`Model Patent Jury Instructions for the Northern District of California at 32, § 4.3a2
`
`(July 16, 2015).
`
`4.3c OBVIOUSNESS
`
`Even though an invention may not have been identically disclosed or
`described before it was made by an inventor, in order to be patentable,
`the invention must also not have been obvious to a person of ordinary
`skill in the field of technology of the patent at the time the invention
`was made.
`
`[Alleged infringer] may establish that a patent claim is invalid by
`showing, by clear and convincing evidence, that the claimed invention
`9
`
`
`
`
`
`Cisco Systems, Inc., EX 1157 Page 12
`
`

`

`would have been obvious to persons having ordinary skill in the art at
`the time the invention was made in the field of [insert the field of the
`invention].
`
`In determining whether a claimed invention is obvious, you must
`consider the level of ordinary skill in the field [of the invention] that
`someone would have had at the time the [invention was made] or
`[patent was filed], the scope and content of the prior art, and any
`differences between the prior art and the claimed invention.
`
`Keep in mind that the existence of each and every element of the
`claimed invention in the prior art does not necessarily prove
`obviousness. Most, if not all, inventions rely on building blocks of
`prior art. In considering whether a claimed invention is obvious, you
`may but are not required to find obviousness if you find that at the
`time of the claimed invention [or the patent’s filing date] there was a
`reason that would have prompted a person having ordinary skill in the
`field of [the invention] to combine the known elements in a way the
`claimed invention does, taking into account such factors as (1)
`whether the claimed invention was merely the predictable result of
`using prior art elements according to their known function(s); (2)
`whether the claimed invention provides an obvious solution to a
`known problem in the relevant field; (3) whether the prior art teaches
`or suggests the desirability of combining elements claimed in the
`invention; (4) whether the prior art teaches away from combining
`elements in the claimed invention; (5) whether it would have been
`
`10
`
`
`
`
`
`
`
`Cisco Systems, Inc., EX 1157 Page 13
`
`

`

`obvious to try the combinations of elements, such as when there is a
`design need or market pressure to solve a problem and there are a
`finite number of identified, predictable solutions; and (6) whether the
`change resulted more from design incentives or other market forces.
`To find it rendered the invention obvious, you must find that the prior
`art provided a reasonable expectation of success. Obvious to try is not
`sufficient in unpredictable technologies.
`
`In determining whether the claimed invention was obvious, consider
`each claim separately. Do not use hindsight, i.e., consider only what
`was known at the time of the invention [or the patent’s filing date].
`
`In making these assessments, you should take into account any
`objective evidence (sometimes called “secondary considerations”) that
`may shed light on the obviousness or not of the claimed invention,
`such as:
`(a) Whether the invention was commercially successful as a result of
`the merits of the claimed invention (rather than the result of design
`needs or market-pressure advertising or similar activities);
`(b) Whether the invention satisfied a long-felt need;
`(c) Whether others had tried and failed to make the invention;
`(d) Whether others invented the invention at roughly the same time;
`(e) Whether others copied the invention;
`(f) Whether there were changes or related technologies or market
`needs contemporaneous with the invention;
`(g) Whether the invention achieved unexpected results;
`
`11
`
`
`
`
`
`
`
`Cisco Systems, Inc., EX 1157 Page 14
`
`

`

`
`
`(h) Whether others in the field praised the invention;
`(i) Whether persons having ordinary skill in the art of the
`invention expressed surprise or disbelief regarding the invention;
`(j) Whether others sought or obtained rights to the patent from
`the patent holder; and
`(k) Whether the inventor proceeded contrary to accepted wisdom
`in the field.
`Federal Circuit Bar Association Model Jury Instructions §4.3c (2014)..
`
`14.
`
`I am also informed that the United States Patent Office supplies its
`
`examining corps with a Manual of Patent Examining Procedure that provides
`
`exemplary rationales that may support a conclusion of obviousness and I apply
`
`these principles in my analysis below, including:
`
`(a) Combining prior art elements according to known methods to
`yield predictable results;
`(b) Simple substitution of one known element for another to
`obtain predictable results;
`(c) Use of known technique to improve similar devices (methods, or
`products) in the same way;
`(d) Applying a known technique to a known device (method, or
`product) ready for improvement to yield predictable results;
`(e) “Obvious
`to
`try” – choosing from a finite number of
`identified, predictable solutions, with a reasonable expectation of
`success;
`(f) Known work in one field of endeavor may prompt variations of it
`12
`
`
`
`
`
`Cisco Systems, Inc., EX 1157 Page 15
`
`

`

`
`
`for use in either the same field or a different one based on design
`incentives or other market forces if the variations are predictable to
`one of ordinary skill in the art; or
`(g) Some teaching, suggestion, or motivation in the prior art that
`would have led one of ordinary skill to modify the prior art reference
`or to combine prior art reference teachings to arrive at the claimed
`invention.
`
`MPEP § 2143.
`

`15.
`
`Legal Standards for Claim Interpretation
`I have been informed and understand that, in Inter Partes Review, the
`
`claim terms are to be given their broadest reasonable interpretation (BRI) in light
`
`of the specification.
`
`C. Legal Standards for a Motion to Amend
`16.
`I have been informed and understand that, in Inter Partes Review, the
`
`patent owner has the burden to show its entitlement to the proposed claim
`
`amendments, including written description support in the original disclosure and
`
`patentability over the prior art.
`
`III. SUMMARY OF THE INSTITUTED GROUNDS AND MR. BATES’S OPINIONS
`17.
`I understand that the Patent Trial and Appeal Board (“Board”)
`
`instituted this Inter Partes review (“IPR”) on Ground 1 (Burger (Ex. 1103) in view
`
`of the knowledge of a POSA), Ground 2 (Burger (Ex. 1103) in view of Alexander
`
`
`
`
`
`13
`
`Cisco Systems, Inc., EX 1157 Page 16
`
`

`

`
`
`(Ex. 1106)), and Ground 3 (Archer (Ex. 1104) in view of the knowledge of a
`
`POSA), as to claims 143-147, 149, 150, 163, and 176-178 of the ‘113 patent.
`
`18. With respect to Grounds 1 and 3, in his declaration in support of
`
`Patent Owner’s Response, Mr. Bates opined that Burger and Archer do not
`
`disclose a “web-enabled processing system” for several reasons:
`
`(a) There is no disclosure that Archer’s server processor 128 or
`
`Burger’s ESP 60 performs the step of establishing voice communications between
`
`two networks nor how this step is performed; and
`
`(b)
`
` There is no disclosure of a call processing system coupled to a
`
`switching facility/tandem switch because Burger or Archer’s gateways are edge
`
`devices not switching facilities (and thus are necessarily connected to a PSTN edge
`
`switch).
`
`19.
`
`In his declaration in support of Patent Owner’s Contingent Motion to
`
`Amend, Patent Owner, Mr. Bates’s opinions overlap with his opinions in his
`
`declaration in support of Patent Owner’s Response regarding Burger and Archer
`
`with respect to substitute Claim 184. In his declaration in support of Patent
`
`Owner’s Contingent Motion to Amend, Mr. Bates opines that Claim 184 is
`
`patentable over all cited art (including Burger and Archer) because the cited art
`
`either discloses a tandem access controller or “TAC” (call processing system)
`
`
`
`
`

`

`

`
`
`external to the PSTN and thus necessarily connected to an edge switch of the
`
`PSTN, or (2) discloses a TAC (call processing system) internal to the PSTN that
`
`does not receive call requests or initiate call requests to establish a call.
`
`20. Thus, Mr. Bates’s opinions regarding the patentability of Claim 143 of
`
`the ‘113 patent and substitute Claim 184 largely overlap.
`
`IV. SUMMARY OF SUBSTITUTE CLAIM 184
`21.
`In its Motion to Amend, Patent Owner proposes to amend current
`
`Claim 143 of the ‘113 patent by making the following amendments:
`
`(a)
`
` Adding the limitation that the first communication network is
`
`the PSTN network and the second communication network is a VOIP.
`
`(b) Changing “controller” to “tandem access controller.”
`
`(c) Adding the limitations that the PSTN telecommunications
`
`network includes “a plurality of edge switches connected to telephones on one side
`
`and PSTN tandem switches on the other side”, “wherein the PSTN tandem
`
`switches includes the particular PSTN tandem switch”, “wherein the PSTN tandem
`
`switches are not the edge switches”, and “wherein the PSTN tandem switches are
`
`not directly connected to any of the telephones.”
`
`(d) Adding the limitation “wherein communications between the
`
`tandem access controller and the particular PSTN tandem switch occur without
`
`
`
`
`
`15
`
`Cisco Systems, Inc., EX 1157 Page 18
`
`

`

`
`
`passing through any edge switches.”
`
`(e) Adding the limitation of “initiating a second call request to
`
`establish a second call . . . without yet answering the first incoming call,”
`
`“answering the first incoming call at the tandem access controller when the second
`
`call is answered,” and “enabling communication between the first call and the
`
`second call by the tandem access controller when the second call is anwered by
`
`connecting the first call to the second call.” Mot. To Amend, Paper 26, 2-4.
`
`V. MR. BATES’S OPINIONS REGARDING THE PATENTABILITY OF SUBSTITUTE
`CLAIM 184
`
`22.
`
`In Patent Owner’s Motion to Amend, Mr. Bates opined that the prior
`
`art of record and prior art known to him and the Patent Owner should be grouped
`
`into two categories, external art (EXT Art) and internal art (INT Art). Ex. 2040,
`
`¶¶63-64.
`
`23.
`
`In his declaration in support of the Motion to Amend, Mr. Bates
`
`opined that EXT Art teaches “devices external to the PSTN must send or receive
`
`call requests via the PSTN through an edge switch first, not a tandem switch.” Ex.
`
`2040, ¶117. Mr. Bates also opined that INT Art teaches “a closed system, such
`
`that its tandem switches and SCPs are not even capable of processing a call that is
`
`sent over a network other than the PSTN.” Ex. 2040, ¶¶141-142.
`
`24.
`
`In his declaration in support of the Motion to Amend, Mr. Bates stated
`
`
`
`
`
`16
`
`Cisco Systems, Inc., EX 1157 Page 19
`
`

`

`
`
`that he “did not believe Petitioners have come forward with a single document that
`
`shows something akin to a TAC connected to a tandem switch that does not
`
`communicate call requests through an edge switch.” Ex. 2040, ¶145. Mr. Bates
`
`also stated that he was “not aware of any such system.” Id.
`
`25.
`
`In his declaration, Mr. Bates also provides testimony regarding the
`
`state of the art in May 2000 and what third parties were developing, including the
`
`“Baby Bells”, but does not provide factual support for any of this testimony. Id..,
`
`¶¶146-149. Mr. Bates’s opinion that Substitute Claim 184 is patentable over the
`
`prior art is focused on the following two features that Mr. Bates opines are not
`
`known or suggested in any known prior art:
`
`(a) The TAC communicates, including communication related to
`
`call requests, with the tandem switch without passing through an edge switch (the
`
`“First Added Feature”). Ex. 2040, ¶152.
`
`(b) The TAC performs the steps initiating a second call without yet
`
`answering the first incoming call and answering the first incoming call when the
`
`second call is answered. (the “Second Added Feature”). Id.
`
`26. However, in my opinion, these two features are present in the prior art
`
`already of record in the Petition in this IPR, as well as newly cited art that I discuss
`
`below. Specifically, it is my opinion that Burger and Archer, includes both of
`
`
`
`
`
`17
`
`Cisco Systems, Inc., EX 1157 Page 20
`
`

`

`
`
`these features. Likewise, it is my opinion that the newly cited art of U.S. Patent
`
`No. 6,442,169 to Lewis (“Lewis”) (Ex. 1146) and U.S. Patent No. 6,333,931
`
`(“LaPier”) (Ex. 1147) both disclose these two features.
`
`VI. ARCHER DISCLOSES THE FIRST AND SECOND ADDED FEATURES
`27.
`In his declaration, Mr. Bates opines that Archer’s gateway 126
`
`interconnecting the PSTN 118 (136) to a packet network 130 must be connected to
`
`an edge switch. Ex. 2040, ¶¶84-86, 120. I disagree with his opinion.
`
`28. Server processor 128 in conjunction with database 138 and gateway
`
`1261 coupled to a tandem switch in PSTN 118 (136) as described in Archer as the
`
`
`
` 1
`
` Mr. Bates incorrectly states that Archer doesn’t use the term “gateway” with
`
`respect to component 126 (or 132) is inaccurate. See Ex. 1104, 5:34-35
`
`(“Converter 126 can also be referred to as a gateway.”), 5:59-60 (“In general
`
`PSTN-to-IP network gateway (i.e. converter 126) . . .”). Moreover, Mr. Bates’s
`
`reliance on Archer’s other nomenclature for the same component (“converter”) as
`
`indicating that gateway 126 only converts signals between analog and digital
`
`formats is also incorrect as Archer explicitly discloses that gateway 126 may
`
`“convert” or “translate” circuit-switched digital voice (PCM) into multiple
`
`
`
`
`
`18
`
`Cisco Systems, Inc., EX 1157 Page 21
`
`

`

`
`
`claimed “call processing system coupled to a switching facility.” Ex. 1156, ¶¶158-
`
`164. It is my opinion that these same components also correspond to the newly
`
`claimed “tandem access controller (TAC) coupled to the particular PSTN tandem
`
`switch” that includes the two newly added features identified above.
`
`B. Arches Discloses the First Added Feature
`29.
`In my opinion, a POSA would understand that Archer discloses the
`
`First Added Feature as server processor 128 communicates with the tandem switch
`
`in PSTN 118 (136) via gateway 126 and without passing through an edge switch.
`
`As I outline below, a POSA would understand that Archer’s gateway 126 is not an
`
`edge device or an edge switch and communicates on the PSTN using SS7 signaling
`
`and a digital voice protocol used by PSTN tandem switches.
`
`30.
`
`In my opinion, Archer discloses that gateway 1262, passes information
`
`
`
`encoding schemes and digital packets suitable for packet networks (e.g. IP
`
`packets). See id., 5:27-28; 5:59-62; 6:7-9; 8:18-21; 9:14-15; 11:23-25.
`
`2 During his deposition, which I attended, Mr. Bates acknowledged that there is no
`
`such thing as an “edge switch” in IP networks. Ex. 1148, 110:9-13; 114:17-20;
`
`178:21-24. Thus, in my opinion, gateway 126 (which clearly has an IP address
`
`
`
`
`
`19
`
`Cisco Systems, Inc., EX 1157 Page 22
`
`

`

`
`
`(e.g. voice and signaling) through it, and sends and receives such information in
`
`digital formats3 (e.g. PCM voice and IP voice packets). Ex. 1104, 5:10-11
`
`(“Circuit-switched network 118 can be . . . a digital network”); 5:23-27 (“[T]he
`
`heart of most telephone networks today is digital.”); 5:33-35; 5:42-46; 5:59-62
`
`(“PSTN-to-IP network gateway (i.e. converter 126) should be able to support the
`
`translation of PCM to multiple encoding schemes to interwork with software from
`
`various vendors.”); Ex. 1156, ¶¶133-165, 174-178, 189-192.
`
`31.
`
`In my opinion, a POSA would understand that gateway 126
`
`communicates both VoIP and PSTN signaling (i.e. SS7) over PSTN 118 (136) and
`
`IP network 130 such as, for example, when it receives VoIP call notification
`
`messages from server processor 128, and translates such messages into
