`
`Petitioner and Dr. Goodman erroneously allege that tho “terminology in
`
`Boer” supports or “implies” tho use of a masterfslave system. (See Paper 4 at 16-
`
`1?; Ex. 1220 at 1192-96.) The Petition’s hollow analysis begins with a comparison
`
`of two figures in which one is rotated to make “striking similarities” between the
`
`two. Paper 4 at 1?. Such analysis is disingenuous and completely ignores the

`
`in the art would have appreciated that the general discussion of CSMAICD in
`
`Upendeeroopman (for which the random backofi' is a form of “collision
`
`avoidance” as the designator “CA” is used in Boer), would apply when
`
`considering the technology described in Boer.

`“[A] master controls the initiation of its own
`transmission to the tribs and permits transmission
`from a trib only when that trib has been selected.”
`‘580 Patent, 4:7-9
`
`“…any unilateral transmission by a trib that has not
`been addressed by the master transceiver will violate
`the multipoint protocol.”
`
`‘580 Patent, 5:4-6
`
`“At the end of trailing sequence 38, trib 26a transmits
`training sequence 42 to initiate a communication
`session with master transceiver 24. Because master
`transceiver 24 selected trib 26a for communication as
`part of training sequence 34, trib 26a is the only
`modem that will return a transmission. Thus, trib 26a
`transmits data 44 destined for master transceiver 24
`followed by trailing sequence 46 to terminate the
`communication session.”
`
`‘580 Patent, 4:27-34
`
`18
`
`Master/Slave
`
`“In this protocol [Master/slave polling], a centrally
`assigned master periodically sends a polling message
`to the slave nodes, giving them explicit permission to
`transmit on the network.”
`
`“This protocol is ideal for a centralized data-
`acquisition system where peer-to-peer communication
`and global prioritization are not required. However,
`the single point-of-failure from the master node (or
`the cost of installing redundant master hardware) is
`often unacceptable. Additionally, the polling process
`consumes considerable bandwidth regardless of
`network load (poor efficiency).”

`“The law in an inter partes review is clear: a “claim term will not receive its
`ordinary meaning if the patentee acted as his own lexicographer and clearly set
`forth a definition of the disputed claim term in either the specification or
`prosecution history.” Cisco Systems, Inc. v. AIP Acquisition, LLC, 2014 WL
`2364452, at *6 (Patent Tr. & App. Bd., May 27, 2014) (emphasis added) quoting
`CCS Fitness, 288 F.3d at 1366 (Fed. Cir. 2002); accord Advanced Fiber Techs.
`Trust v. J&L Fiber Servs., 674 F.3d 1365, 1374 (Fed. Cir. 2012); Macronix Int’l¸
`IPR2014-00106 (Paper 13 at 6, Apr. 24, 2014). Thus, the patentee’s definition in
`either the specification or prosecution history governs.”
`
`“Further, in Abbott Labs. v. Novopharm Ltd., 323 F.3d 1324 (Fed. Cir. 2003), the
`Federal Circuit held that a patent specification’s use of the letters “i.e.” (Latin for
`“that is”) in conjunction with a claim term typically connotes a binding
`definition. 323 F.3d 1324, 1330 (Fed. Cir. 2003).”

`

`

`Conclusion
`
`• Petition fails to show that the
`alleged combination renders the
`claims obvious:
`− Dr. Goodman’s failure to read
`and fully understand the art
`upon which he relies
`− No motivation to combine
`Master/Slave with Boer
`− One of skill in the art would
`not combine a master/slave
`protocol with Boer
`
`• Alleged combination fails to
`disclose every element of the
`claims:
`− As properly construed, Boer
`does not disclose “two types
`of modulation methods”
`− DBPSK and DQPSK are not
`different “types” of
`modulation
`− PPM is an encoding
`technique, not a modulation
`technique that varies the
`carrier wave
