`
`I.
`
`QUALIFICATIONS AND PROFESSIONAL EXPERIENCE
`
`4.
`
`I received a bachelor degree (with Honors) in 1989 from the Indian
`
`Institute of Technology, Kharagpur, and M.S. and Ph.D. degrees in 1991 and 1994
`
`from Rice University, Houston, TX, all in electrical engineering.
`
`5.
`
`I was a Research Associate at the Wireless Information Network
`
`Laboratory (“WINLAB”), Department of Electrical & Computer Engineering,
`
`Rutgers University, between 1994 and 1996. In September 1996, I joined the
`
`faculty of Department of Electrical & Computer Engineering at Rutgers where I
`
`became Associate Professor in 2001, Professor in 2003, and Distinguished
`
`Professor in 2014. I also served as the Peter D. Cherasia Endowed Faculty Scholar
`
`at Rutgers University from 2010 to 2014. Currently, I also serve as Associate
`
`Director at WINLAB where I conduct research in various aspects of wireless
`
`systems and networks. I teach courses at Rutgers on the topics of Wireless
`
`System Design, Wireless Communication Technologies, Wireless Revolution,
`
`Detection and Estimation Theory and Introduction to Computing for Engineers. I
`
`was a visiting faculty fellow in the Department of Electrical Engineering,
`
`Princeton University in Fall 2002 and a visiting faculty at the Indian Institute of
`
`Science in Spring 2003.
`
`3
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`
`6. My research focuses on wireless networks and communications, and I
`
`have worked on various aspects of networking and wireless devices. Over the last
`
`25 years, I have published a wide range of articles on various aspects of wireless
`
`systems including techniques for data transmission, resource allocation strategies,
`
`mathematical modeling, and performance analysis. Using constructs from game
`
`theory, communications and networking, my work has focused on system
`
`modeling and performance, signal processing as well as radio resource
`
`management for enabling wireless technologies to support various applications. I
`
`have coauthored 2 books on wireless networks (Principles of Cognitive Radio,
`
`Cambridge (2012) and Wireless Networks: Multiuser Detection in Cross-Layer
`
`Design, Springer (2005)), 6 book chapters and published over 200 papers in
`
`prestigious international journals and conferences. I have also given numerous
`
`invited presentations at a variety of industry, government, and academic forums.
`
`7.
`
`Specifically, I have been doing precompetitive research in various
`
`aspects of wireless data transmission for over 25 years addressing PHY, MAC and
`
`Network layer issues. I have made seminal research contributions to wireless data
`
`communications on issues ranging from the systems level (such as power control,
`
`capacity evaluation, protocol design, medium access control, and radio resource
`
`management) to the physical layer (such as detection and estimation). My
`
`4
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`expertise includes cellular systems such as for 2G, 3G and 4G and I have published
`
`papers on a wide variety of topics related to the design and operation of
`
`GSM/TDMA, CDMA and LTE based systems. During this time, I have also
`
`worked extensively on wireless local area network (WLAN) technologies as well
`
`as wireless ad-hoc and sensor networks, and as such I am quite familiar with
`
`802.11 and Bluetooth.
`
`8.
`
`I also teach both graduate and undergraduate courses at Rutgers where
`
`I introduce students to the wide area network (WAN) cellular and local area
`
`network (LAN) technologies mentioned above. I have also served as a technical
`
`consultant since its inception in 2002 to the company Mojo Networks Inc., a world
`
`leader in enterprise network security for WLANs that offers the next generation of
`
`intelligent edge, secure, and flexible WiFi solutions. I am familiar with the early
`
`developments in the area of Bluetooth technology and have served on graduate
`
`thesis defense committees even as early as the year 2000.
`
`9.
`
`I have received several prestigious awards relating to my research on
`
`wireless networks and communications: the 2015 IEEE COMSOC Advances in
`
`Communications Award for seminal work on power control in wireless data
`
`networks (this is the highest paper award given by the IEEE Communications
`
`Society), the 2014 IEEE Donald G. Fink Award (recognizes the most outstanding
`
`5
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`tutorial paper across all IEEE publications) for the paper titled “Frontiers of
`
`Wireless and Mobile Communications” that discusses the historical and future
`
`landscape of both WAN and LAN wireless technologies, and the Fred W. Ellersick
`
`Prize from the IEEE Communications Society in 2009 for work on dynamic
`
`spectrum access models and spectrum policy. I also received the Peter D. Cherasia
`
`Faculty Scholar Award from Rutgers University in 2010, the National Science
`
`Foundation Career Award in 1998, and the Institute Silver Medal from the Indian
`
`Institute of Technology, Kharagpur in 1989.
`
`10.
`
`I have served as an Editor for the journals IEEE Communication
`
`Letters (1999- 2002) and IEEE Transactions on Wireless Communications (2002-
`
`2004). I have also served as a guest editor of the IEEE JSAC Special Issues on
`
`Adaptive, Spectrum Agile and Cognitive Radio Networks (2007) and Game
`
`Theory in Communication Systems (2008). I was elected Fellow of the IEEE for
`
`“contributions to wireless data transmission.” I have also served as a
`
`Distinguished Lecturer of the IEEE Communications Society. My curriculum
`
`vitae is attached to this declaration.
`
`II. RELEVANT LEGAL STANDARDS
`
`11. My understanding of the relevant legal standards is based on
`
`information given by Patent Owner’s counsel. I understand from counsel that in
`
`6
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`the inter partes review proceeding, such as this one, the claims of a patent are
`
`construed from the perspective of one of ordinary skill in the art at the time of the
`
`claimed invention and are given their broadest reasonable construction consistent
`
`with the specification.
`
`12.
`
`It is my understanding that an invention is unpatentable if the
`
`differences between the invention and the prior art are such that the subject matter
`
`of the invention as a whole would have been obvious at the time the invention was
`
`made to a person having ordinary skill in the art. I further understand that
`
`obviousness is determined by evaluating: (1) the scope and content of the prior art,
`
`(2) the differences between the prior art and the claim, (3) the level of ordinary
`
`skill in the art, and (4) secondary considerations of nonobviousness. To establish
`
`obviousness based on a combination of the elements disclosed in the prior art, it is
`
`my understanding that a petitioner must identify a specific combination that
`
`teaches all limitations and establish that a person of ordinary skill in the art at the
`
`time of the claimed invention would have found it obvious to make that
`
`combination.
`
`13. To guard against hindsight and an unwarranted finding of
`
`obviousness, I understand that an important component of any obviousness inquiry
`
`is whether the petitioner has identified any teaching, suggestion or motivation that
`
`7
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`would have prompted a person of ordinary skill in the art to make the claimed
`
`combination and have a reasonable expectation of success in doing so. I
`
`understand that this test should not be rigidly applied, but can be an important tool
`
`to avoid the use of hindsight in the determination of obviousness.
`
`14.
`
`I further understand that the teaching, suggestion, or motivation may
`
`be found explicitly or implicitly: (1) in the prior art; (2) in the knowledge of those
`
`of ordinary skill in the art that certain references, or disclosures in those references,
`
`are of special interest or importance in the field; or (3) from the nature of the
`
`problem to be solved. Additionally, I understand that the legal determination of
`
`the motivation to combine references allows recourse to logic, judgment, and
`
`common sense. In order to resist the temptation to read into prior art the teachings
`
`of the invention in issue, however, it should be apparent that “common sense”
`
`should not be conflated with what appears obvious in hindsight.
`
`15.
`
`I understand that if the teachings of a prior art reference would lead a
`
`person of ordinary skill in the art to make a modification that would render another
`
`prior art device inoperable, then such a modification would generally not be
`
`obvious. I also understand that if a proposed modification would render the prior
`
`art invention being modified unsatisfactory for its intended purpose, then there is
`
`no suggestion or motivation to make the proposed modification.

`
`
`
`III. DEFINITION OF THE PERSON OF SKILL IN THE ART
`
`16. Dr. Kiaei and Petitioner have alleged a person of ordinary skill in the
`
`art in the field of the invention claimed in the ’033 patent, would have had a
`
`Master’s of Science Degree (or a similar technical Master’s Degree, or higher
`
`degree) in an academic area emphasizing electrical engineering, computer
`
`engineering, or computer science with a concentration in communication and
`
`networking systems or, alternatively, a Bachelor’s Degree (or higher degree) in an
`
`academic area emphasizing electrical or computer engineering and having two or
`
`more years of experience in communication and networking systems. For the
`
`purposes of my opinions, I have used this definition.
`
`17.
`
`I am familiar with the knowledge and capabilities of one of ordinary
`
`skill in the field of the ’033 Patent in 2001, at the time of the filing of the patent
`
`application leading to the ’033 Patent, based on my experience (1) with
`
`collaboration with the industry, (2) with undergraduate and post-graduate students,
`
`(3) with colleagues from academia, and (4) with my role as Associate Director of
`
`WINLAB at Rutgers. Unless otherwise stated, my statements made herein refer to
`
`the knowledge of one of ordinary skill in the field of the invention claimed in the
`
`’033 Patent.

`Patent 7,039,033
`
`
`
`IV.
`
` THE ’033 PATENT
`
`18. The ’033 Patent is directed to “a system that accesses information
`
`from a wide area network (‘WAN’), such as the Internet, and local wireless devices
`
`in response to short-range radio signals.” Ex. 1001, 4:8–11; Abstract. The system
`
`includes a wireless gateway device that is coupled to the WAN and to a personal
`
`area network (“PAN”). Id. at Abstract; FIG. 1. The wireless gateway device
`
`allows devices connected on the PAN to connect to the WAN. The wireless
`
`gateway device also includes software components that allow devices on the PAN
`
`to communicate and share services, and includes the ability to provide security to
`
`the network.
`
`19. Figure 1 provides an illustration of the system described in the ’033
`
`Patent and is depicted below:
`
`Figure 1: ’033 Patent, Figure 1
`
`
`
`10
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`
`
`The Gateway Device 106 communicates with one or more terminals 107 to form a
`
`personal area network (“PAN”) using short-range radio signals 110. Id. at 4:16-21.
`
`The PAN is implemented using local wireless technology such as Bluetooth or
`
`802.11, which is commonly referred to as Wi-Fi. Id. at 4:25-35. The Gateway
`
`Device 106 is coupled to cellular network 105 and can communicate with, for
`
`example, Server 101 and Server 102 via carrier backbone 104. Id. at 4:36-59. In
`
`so doing, Servers 101 and 102 can provide information, such as web pages or
`
`application software components, to terminals 107 in the WLAN by way of the
`
`Gateway Device 106. Id. at 4:49-54.
`
`20. The software components described in the ’033 Patent are what
`
`enables the Gateway Device to connect the terminals on the PAN to the WAN and
`
`offer network management and security functions. As part of the architecture, the
`
`Gateway Device includes a “service repository software component 704.” The
`
`service repository software component “allows applications 406, which run on a
`
`gateway device 106 or terminals 107, to discover what services are offered by a
`
`PAN, and to determine the characteristics of the available services.” Id. at 12:11-
`
`14.
`
`21. The Gateway Device 106 also includes a “plug and play component.”
`
`The “plug and play” capability of Gateway Device 106 allows it to identify a new
`
`11
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`terminal and determine the necessary software required to support the new
`
`terminal. Id. at 10:11-37; Fig. 7. Terminals connecting to the PAN are not
`
`necessarily readily supported by the Gateway Device 106. For example, the ’033
`
`Patent identifies the introduction of “thin” terminals to the PAN as an example of
`
`utilizing the “plug and play” capability of the Gateway Device 106. Id. at 10:18-
`
`35. Thin terminals do not have embedded application code or data. Id. In order to
`
`support these types of devices, the “plug and play component” uses the terminals’
`
`identification to find, download, and execute the software necessary for the
`
`Gateway Device 106 to support the terminal. Id. at 10:11-37.
`
`V. OPINION ON CLAIM CONSTRUCTION
`
`22.
`
`It is my understanding that in this inter partes review proceedings, the
`
`claim terms are to be given their broadest reasonable interpretation consistent with
`
`the specification and file history of the ’033 Patent, as understood by one of
`
`ordinary skill in the art. I understand that claim construction is the common
`
`terminology used to describe the interpretation of claim terms.
`
`23.
`
`It is also my understanding that Petitioner argues that claim language:
`
`“identifies whether the service is available at a particular time,” found in claim 4 of
`
`the ’033 Patent, should be construed to encompass “the service being registered.”
`
`Paper 2, 9. Consistent with my understanding of claim interpretation, my review
`
`12
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`of the specification, and as one of ordinary skill in the art at the time of the
`
`invention, I disagree with Petitioner that the identified claim language needs a
`
`construction. Further, I disagree that a person of ordinary skill in the art would
`
`have understood the language “identifies whether the service is available at a
`
`particular time” to encompass “the service being registered.”
`
`24.
`
` It is my opinion that the claim language of claim 4 would have been
`
`understood by a person of ordinary skill in the art without the need for claim
`
`construction. Claim 4 states:
`
`The system of claim 1, wherein the service repository software
`component identifies whether the service is available at a particular
`time.
`
`Ex. 1001, 16:4-6 (emphasis added). It is my opinion that in light of the
`
`specification of the ’033 Patent, a person of ordinary skill in the art would have
`
`understood the language of claim 4 without a construction and that person’s
`
`understanding would not encompass “the service being registered.”
`
`25.
`
`It is clear from the specification of the ’033 Patent that the service
`
`repository software component 704 is capable of identifying whether a service is
`
`available at a particular time. The specification states:
`
`In an embodiment of the present invention, service repository
`component 704 describes the terminals and the services that are
`available at a particular time, but service repository software
`component 704 does not describe the current status of the service.
`
`13
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`Ex. 1001, 13:5-9 (emphasis added). This action is separate and distinct from
`
`registering a service.
`
`26. A person of ordinary skill in the art would have understood that
`
`“identifying whether a service is available at a particular time” necessarily occurs
`
`after a service has been registered and is not the same process. In fact, the ’033
`
`Patent describes that the service repository software component offers a plurality
`
`of functions and identifies service registration as the first function. The ’033
`
`Patent states “[f]irst, service repository software component 704 provides service
`
`registration of a service offered by application, or a hardware capability offered by
`
`terminal driver.” Ex. 1001, 12:35-37. A service must be registered before it can
`
`be identified.
`
`27. The distinction between the service registration and service
`
`identification is further illustrated by Figure 7 of the ’033 Patent. Below, I have
`
`included an annotated version of Figure 7. As shown below, the service repository
`
`704 separately identifies “service registration and unregistration” and “service
`
`enumeration.” A person of ordinary skill in the art would have recognized that
`
`these are two separate functions.

`
`VI. BACKGROUND OF TECHNOLOGY
`
`A. Bluetooth
`
`28. Bluetooth is a local wireless technology that connects devices using
`
`short-range radio signals. Ex. 2305, p. 41. The Bluetooth system provides a point-
`
`to-point connection, if only two devices are connected, or a point-to-multipoint
`
`connection, if more than two devices are connected. This is illustrated below:
`
`15
`
`
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`Figure 3: Ex. 2305, Figure 1.2
`
`
`
`Section (a) in the figure above depicts a point-to-point connection of two devices.
`
`When two or more devices are connected they share the same “channel” using
`
`frequency hopping. “Two or more units sharing the same channel form a piconet.”
`
`Id. The piconet depicted in Section (b) in the figure above depicts a point-to-
`
`multipoint connection of four devices. A piconet can be formed by up to eight
`
`devices. Id. at 42.
`
`29.
`
`In each piconet, one Bluetooth device acts as the master and the
`
`remaining units act as slaves. Id. at 41-42. “The piconet is synchronized by the
`
`system clock of the master.” Id. at 87. Slave devices use a timing offset to adapt
`
`their native clocks to match the master clock. Id. As depicted above, the master
`
`16
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`device establishes the connection between the slave devices. The master device
`
`controls all communication in a piconet. There is no direct communication
`
`between slave devices on the piconet channel.
`
`30. A Bluetooth device may participate concurrently in two or more
`
`piconets. When multiple piconets are connected in this manner, they form a
`
`scatternet. Id. at 42. A scatternet is depicted in Section (c) of the figure above.
`
`Each piconet can only have one master device. A master device in one piconet can
`
`be a slave device in another piconet. I have depicted an example of this below:
`
`
`
`Figure 4: Illustration of a Bluetooth Scatternet
`
`31.
`
`In the figure above, the laptop computer is the master (MA) of piconet
`
`A, with the mobile phone (SA) and the printer (SA) as slave devices in piconet A.
`
`The mobile phone is the master of piconet B (MB), with only the laptop (SB) as its
`
`17
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`slave device. Both the laptop and the mobile phone simultaneously act as master
`
`and slave devices on independent piconets, with piconet B, being a “sub-piconet”
`
`within piconet A.
`
`VII. THE COMBINATION OF MARCHAND, NURMANN, AND
`VILANDER
`
`A. Marchand
`
`32. Marchand2 (PCT Publication Number WO 2000/041529 and U.S.
`
`Patent Application No. 09/541,529) is directed at a Bluetooth piconet that has been
`
`extended into an Internet Protocol (IP) wireless local area network implementing
`
`JINI java technology in order to utilize JINI technology for sharing services
`
`between devices in the piconet. Ex. 1005, Abstract; 5:23-25; 6:25-27.
`
`Additionally a mobile phone connected to the piconet is configured to act as a
`
`gateway to provide a call control interface between the wireless IP network and
`
`other devices in the piconet. Ex. 1005, Abstract.

`
`Underlying Technology
`
`33. A person of ordinary skill in the art would have understood that the
`
`operation of the network and the devices described in Marchand are dependent on
`
`the underlying technology. Specifically, when evaluating Marchand, a person of
`
`

`
`and Marchand Priority that affect my analysis.

`
`
`
`ordinary skill in the art would have considered the implementation of Bluetooth
`
`wireless technology extended into an IP wireless LAN and JINI java technology.
`
`Marchand makes clear that the use of a Bluetooth piconet extended into an Internet
`
`Protocol (IP) wireless LAN implementing JINI java technology is essential to the
`
`operation of the network and devices described in Marchand. Marchand explains
`
`that in order for devices in the Bluetooth piconet to share services each device
`
`must be Bluetooth compliant and JINI/Java capable. Ex. 1005, 7:9-11.
`
`34. Marchand states that to be Bluetooth compliant, each device would
`
`include a Bluetooth chipset. Ex. 1005, Abstract; 2:11-16. Further, each device
`
`operates using a specific protocol stack. The protocol stack is defined in Marchand
`
`and illustrated in Marchand’s Figure 2, as shown below:
`
`
`Figure 5: (Ex. 1005) Marchand, Figure 2
`
`35. As shown in Figure 2, each device in Marchand’s Bluetooth piconet
`
`includes a physical layer 15 and a link layer 16, identified as Bluetooth layers of
`
`19
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`the protocol stack. Ex. 1005, Fig. 2. In addition, each device includes a network
`
`transport (IP) layer 17, an operating system layer 18, a Java technology layer 19,
`
`and a JINI technology layer 20. Ex. 1005, 6:14-22.
`
`36. Marchand describes that the underlying technology used to create the
`
`local area network is Bluetooth wireless technology. Ex. 1005, Abstract; 2:7-25;
`
`FIGs. 1-4. Marchand states that “Bluetooth wireless technology allows users to
`
`make effortless, wireless, and instant connections between various communication
`
`devices such as mobile phones and desktop and laptop computers.” Ex. 1005, 2:7-
`
`9. Marchand includes an overview of how Bluetooth devices connect and operate.
`
`Id. at 2:7-26. Specifically, two or Bluetooth devices more devices connect to form
`
`a piconet. Id. When a piconet is established one device acts as the master while
`
`the rest of the devices are slaves, and all of the devices have the same priority
`
`synchronized. As discussed above in Section VI.A, all of the devices are
`
`synchronized to the master devices clock. Ex. 2305, p. 87. The devices connect in
`
`point-to-point and point-to-multipoint connections. Ex. 1005, 2:20-21. These
`
`types of connections are supported because the master device is connected to each
`
`of the slave devices and all of the communications pass between the slave devices
`
`and the master. Slave devices on the same piconet cannot communicate directly
`
`20
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`with one another. Marchand also identifies that devices may be connected to more
`
`than one piconet. See Ex. 1005, 2:25-26.
`
`37.
`
`In Marchand, JINI technology is used to allow devices in its described
`
`network to share services. JINI technology is “a Java-technology-centered,
`
`distributed software system for simplicity, flexibility and federation.” Ex. 1005,
`
`2:27-28, Abstract. “The JINI architecture provides mechanisms for machines or
`
`programs to enter into a federation where each machine or program offers
`
`resources to other members of the federation and uses resources as needed. Ex.
`
`1005, 2:28-31. A person of ordinary skill in the art would have understood, at
`
`least, the general operation of JINI technology.
`
`38. The JINI architecture exploits the ability to move java language code
`
`from machine to machine, to allow various connected devices to use services
`
`offered by other devices in the network. Ex. 1005, 2:28-31. JINI technology relies
`
`on the use of a JINI lookup service (LUS) to offer and share services. Ex. 1009, p.
`
`23. The JINI LUS contains a list of all services offered on a network and allows
`
`devices to share those services. Ex. 1005, 3:11-12. There are a wide variety of
`
`services that can be offered through JINI technology including, “devices such as
`
`printers, displays, or disks; software such as applications or utilities; information
`
`such as databases and files; and users of the system.” Ex. 1009, pp. 79-80.
`
`21
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`Without the JINI LUS, devices on Marchand’s network would not be able to share
`
`and use services.
`
`39. When a device implementing JINI technology joins a JINI-Java
`
`network, the devices undergo a discovery and join process. Ex. 1009, p. 23.
`
`Through this process, the joining device discovers a JINI Lookup service (LUS)
`
`and publishes the services that it can offer to the network. Id. As part of
`
`publishing its service, the joining device transfers java code to the JINI LUS. Id.
`
`The java code is referred to a proxy object or java object. Id. This java language
`
`code is a small amount of code used to identify the services the device offers and
`
`to establish an interface with that service. Id.; see also Ex. 1005, 3:13-14. The
`
`JINI Lookup service stores this java object and creates a list of all of the services
`
`available on the network. Ex. 1009, pp. 22-23; Ex. 1005, 3:11-12.
`
`40. When a JINI java capable device on the network would like to use a
`
`service offered by another device in the network, it sends a request to the JINI
`
`LUS. Ex. 1009, p. 22. The JINI LUS then transfers the java code necessary to
`
`access that service. Id. at p. 23. For example, if a printer joins a network utilizing
`
`JINI technology, the printer will publish its printing service to the network by
`
`transferring java code to the JINI LUS. Id. at 22. The java code includes the
`
`printer’s information and a method to implement its printer interface. Ex. 1009,
`
`22
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`23. When another device in the network needs to print, the device will ask the
`
`JINI LUS if any printer services are available. Id. The JINI LUS provides the
`
`printer’s java code to the requesting device, which will automatically download
`
`that java code from the JINI LUS, if it was not previously downloaded. Id. at 24.
`
`The device can send the printer requests by invoking the methods provided by the
`
`java code to implement the printer interface. Id.
`
`41. When the client issues the printer request it invokes the methods
`
`established by the proxy object. Id. The proxy object, now contained on the
`
`device, communicates with the printer as it needs to in order to execute the
`
`requests. Id. A person of ordinary skill in the art would have appreciated that JINI
`
`technology does not define the protocol between the proxy object on the device
`
`and the printer. Id. at 24-25. The protocol is defined by printer and the proxy
`
`object. Id.
`
`2. Operation of Marchand’s Network and Devices
`
`42. Operating in accordance with the underlying technology, Marchand
`
`describes that the devices are able to connect to form a Bluetooth piconet. Each
`
`device includes the protocol stack described above that allows the Bluetooth
`
`piconet to be extended into an IP wireless LAN and implement JINI and Java
`
`23
`
`
`
`IPR2015-01444
`Patent 7,039,033
`
`
`
`technologies. This allows the devices on Marchand to share services with one
`
`another.
`
`43. While identifying the various services that can be used, Marchand
`
`particularly describes the protocol for implementing a call control service offered
`
`by the mobile phone. The call control service is the only service that Marchand’s
`
`mobile gateway is described as providing.
`
`44. Marchand describes that the mobile phone is able to connect to the
`
`piconet and act as a gateway between the other devices and a wireless IP network.
`
`Id. at 10:15-16, 12:6-10, 7:12-14. This gateway mobile phone “publishes” its call
`
`control service to the LUS allowing other devices in the piconet to detect and
`
`utilize this service. Id. at 8:11-15; FIG. 3. The other Bluetooth devices on the
`
`piconet perform JINI defined “discovery and join” protocols “to locate the LUS
`
`and upload all of its services’ interfaces, including call control services.” Id. at
`
`8:12-20. Through this process, other Bluetooth devices are able to utilize the call
`
`control client of the gateway mobile phone to connect to the wireless IP network.
