`
`Dear Mr. Edward H. Moura,
`
`We are contacting you, as the agent for service of process for
`Alladvantage.com (see Attachment A), to inform you of the ongoing inter
`partes reviews (IPR2015-01956 and IPR2015-01957) of United States
`Patent No. 6,519,581 B1, titled “Collection of Information Regarding a
`Device or a User of a Device Across a Communication Link” (“the ’581
`patent,” Attachment B). These proceedings are before the Patent Trial and
`Appeal Board of the United States Patent and Trademark Office, and are
`currently awaiting a final written decision from the Board regarding the
`patentability of claims in the ’581 patent. The final written decisions are
`expected to be issued by April 18, 2017.
`
`In both proceedings, Petitioners, Old Republic General Insurance Group,
`Inc.; Old Republic Insurance Company; Old Republic Title Insurance
`Group, Inc.; and Old Republic National Title Insurance Company
`(collectively “Old Republic”), filed petitions on September 28, 2015
`challenging the patentability of claims in the ’581 patent. The petitions filed
`in IPR2015-01956 and IPR2015-01957 are enclosed (Attachments C and D).
`
`On April 18, 2016, the Patent Trial and Appeal Board instituted inter partes
`review proceedings in both IPR2015-01956 and IPR2015-01957. The
`Decision to Institute in IPR2015-01956 and IPR2015-01957 are also
`enclosed (Attachments E and F).
`
`Until recently, Intellectual Ventures I LLC has participated in IPR2015-
`01956 and IPR2015-01957 as the purported Patent Owner of the ’581 patent.
`However, in related litigation between Intellectual Ventures I LLC and Old
`Republic, the United States Court of Appeals for the Federal Circuit issued a
`decision on March 7, 2017 that affirmed a district court’s dismissal of
`
`P.O. Box 1450, Alexandria, Virginia 22313-1450 – WWW.USPTO.GOV
`
`
`

`

`Intellectual Ventures I LLC’s patent infringement claims based on the ’581
`patent (Attachment G). On pages 4 through 12 of the enclosed copy of this
`Decision, the Federal Circuit determined that an assignment agreement
`between Alladvantage.com and Alset, Inc. “did not convey any rights to the
`’581 patent.” As such, Alladvantage.com may have ownership rights in the
`’581 patent.
`
`If Alladvantage.com plans to participate in IPR2015-01956 and IPR2015-
`01957, please contact the Board within seven (7) business days after
`receipt of this notification. The Board will issue the final written decisions
`in IPR2015-01956 and -01957 by April 18, 2017. To contact the Board,
`please email Trials@uspto.gov and include “IPR2015-01956 and IPR2015-
`01957” and the patent number in the subject line.

`ABSTRACT
`
`A system is provided for collecting information regarding a
`device or a user of a device. Information is collected from
`a discovery agent residing on the computer system. At
`certain times, the agent may be activated to collect the
`information. A sender transmits a discovery rule across a
`communication link to a computer system. The discovery
`agent and the discovery rule are separate code sequences or
`separate programs. The discovery rule is then applied to the
`information received from the discovery agent and the
`resulting information is returned back to the sender. Where
`the sender receives a user request, such as regarding the
`computer system, the discovery rule may be transmitted and
`the sender may use the resulting information to respond to
`the user request.

`
`FIELD OF THE INVENTION
`
`The present invention relates to information collection

`device.

`BACKGROUND

`information. Instead, the discovery agents communicate the
`collected information to a discovery engine, which receives
`collected data from the discovery agents and applies dis(cid:173)
`covery rules to the collected data. The discovery rules
`s determine what, if any, action is to be taken based on the
`collected data.
`In one embodiment, the discovery rule is transmitted
`across a communication link to a computer system and the
`resulting information, e.g. analysis and collected
`10 information, is received back from the computer system
`through the link. In some instances, the sending of the
`discovery rule may be due to a user request. At times, the
`sender of the request is a remote individual. For example, the
`request may be a request for assistance made to a technical
`15 support representative or sales representative. In this case,
`the collected information/analysis information may be used
`to provide a respond to the user request.
`In still other embodiments, the discovery rule is transmit(cid:173)
`ted automatically, when the computer system establishes a
`20 connection with a server.
`In particular embodiments of the invention receives infor(cid:173)
`mation from a discovery agent, which collects information
`when activated. The discover agents may be periodically
`25 activated to collect information. The invention determines a
`discovery rule to be applied to the information received from
`the discovery agent. The discovery rule is then applied to the
`information received from the discovery agent. The discov(cid:173)
`ery agent and the discovery rule are separate code
`30 sequences.
`BRIEF DESCRIPTION OF THE DRAWINGS
`
`Different types of systems and procedures are available
`for collecting or retrieving information from a device or a
`user of a device. The collected information may be used to
`analyze system performance, identify existing problems, or
`identify potential problems. If a problem or potential prob(cid:173)
`lem is identified, a user or administrator of the system is
`notified of the problem and can take an appropriate action.
`Existing procedures for collecting or retrieving informa(cid:173)
`tion are typically contained in a software application or a
`built-in diagnostic routine that performs one or more pro(cid:173)
`cedures to monitor specific portions of a system. Generally,
`these procedures are included in a single application or a
`diagnostic routine that retrieves information about the sys(cid:173)
`tem and analyzes the retrieved information. Therefore, these
`procedures retrieve a particular set of information and
`perform a particular analysis on the information.
`These existing applications or diagnostic routines are not
`easily modified if a user or administrator wants to change the
`information retrieved or change the analysis performed on
`the retrieved information. To make such a change requires
`modifying the application source code or modifying the
`built-in diagnostic routine, both of which can be compli-
`cated and time-consuming.
`Additionally, many existing applications are invoked and
`operated by a user of the system. Instead of running auto(cid:173)
`matically or running in a "background" mode, these appli(cid:173)
`cations are executed at the direction of the user. Thus, to 45
`retrieve data about the system using this type of application,
`the user must install the application and know how to
`operate and command the application. If the application is
`used infrequently (e.g., only when a problem occurs), the
`user is not likely to be proficient when operating the appli- 50
`cation. In this situation, the user may need to re-learn the
`operation of the application before retrieving and analyzing
`data about the system.
`It is therefore desirable to provide a system that collects
`information automatically while requiring minimal interac(cid:173)
`tion with the user of the system. Additionally, it is desirable
`to provide an information collection system that is easily
`modified to collect different types of data and perform
`different operations on the collected data.

`SUMMARY OF THE INVENTION
`Embodiments of the present invention provide a system
`for passively and actively collecting information about a
`device, such as a computing device and/or the user of the
`device. The system uses one or more discovery agents to 65
`collect information about a device or its user. The discovery
`agents do not have intelligence to understand the collected
`
`DETAILED DESCRIPTION

`The following detailed description sets forth numerous
`specific details to provide a thorough understanding of the
`invention. However, those of ordinary skill in the art will

`specific details. In other instances, well-known methods,
`procedures, protocols, components, algorithms, and circuits
`have not been described in detail so as not to obscure the
`invention.
`The present invention provides a system for passively and
`actively collecting information about a device, such as a
`computing device and/or the user of the device. The system
`uses one or more discovery agents (implemented using
`individual programs or code sequences) to collect informa(cid:173)
`tion about a device or its user. The discovery agents them(cid:173)
`selves have no intelligence regarding how to interpret or act
`on the collected data. Instead, the discovery agents merely
`communicate the collected data to a discovery engine, which
`is a central control module for the information collection
`system. The discovery engine receives collected data from
`the discovery agents and applies one or more discovery rules
`to the collected data. The discovery rules determine what, if
`any, action is to be taken based on the collected data. As
`discussed below, the discovery rules may be a series of
`Boolean operations, mathematical equations, or other com- 20
`parisons or evaluations of the collected data.
`The discovery agents are separate programs (or code
`sequences) from the discovery rules, and there is no par(cid:173)
`ticular relationship between the discovery agents and the
`discovery rules. A particular discovery agent may collect 25
`data that is used by one or more discovery rules. Similarly,
`a particular discovery rule may use data collected by one or
`more discovery agents. Thus, if a particular piece of data
`collected by a discovery agent is used by multiple discovery
`rules, that data need only be collected once, rather than 30
`retrieving the required data multiple times (once for each
`discovery rule requiring the information). The discovery
`engine is responsible for determining what data is required
`by a particular discovery rule and activating the appropriate
`discovery agents to collect the required data.
`Since the discovery agents and the discovery rules are not
`linked to one another, new discovery agents can be gener(cid:173)
`ated and existing discovery agents can be modified without
`necessarily requiring a corresponding change to the existing
`discovery rules. Similarly, an existing discovery rule can be
`changed or an additional rule added without necessarily
`making any changes to the existing discovery agents. For
`example, a new discovery rule may be created that uses data
`from existing discovery agents. In this situation, no addi- 45
`tional discovery agents are required to implement the new
`discovery rule. Thus, the operation of the information col(cid:173)
`lection system can be modified without requiring a revision
`of all agents and rules contained in the system.
`The updating of discovery agents and discovery rules can
`be accomplished by downloading agents or rules from a
`server or other device, or installed from a diskette or other
`storage medium. In one embodiment of the invention, new
`or revised agents and rules are downloaded automatically
`from a server to the device when the device establishes a 55
`connection with the server. This embodiment updates the
`agents and rules without requiring any user interaction or
`user control. Since the discovery agents and discovery rules
`are separate programs or code sequences, individual agents
`and rules can be communicated across a common data 60
`communication link, without requiring a high-speed or
`high-bandwidth communication link.
`Particular embodiments of the invention allow an
`individual, such as a technical support representative or a
`sales representative, to download a particular discovery
`agent or discovery rule to a client across a communication
`link, without requiring action by the user of the client. In a

`particular example, the user of a client requests assistance
`from a technical support representative. The technical sup(cid:173)
`port representative can then download discovery agents and
`discovery rules that collect and analyze information about
`the client system. This collected information and analysis is
`communicated back to the technical support representative
`for use in providing assistance to the user of the client.
`FIG. 1 illustrates an embodiment of a client 10 and a
`server 12 capable of implementing the teachings of the
`10 present invention. Client 10 includes multiple discovery
`agents 14a, 14a, 14c, and 14d. Although FIG. 1 illustrates
`four discovery agents, a particular client may include any
`number of discovery agents. Each discovery agent 14a-4d is
`coupled to a discovery engine 16 and is capable of commu-
`15 nicating information from the discovery agent to the dis(cid:173)
`covery engine. Discovery agents 14a-14d collect informa(cid:173)
`tion about the client or the user of client 10. The information
`collected may include the hardware and software configu(cid:173)
`ration of client 10 and the hobbies or personal interests of the
`user of client 10. As discussed in greater detail below,
`discovery engine 16 is responsible for activating particular
`discovery agents, thereby causing the activated agents to
`collect data about client 10 or the user of client 10. The
`information collected by discovery agents 14a-4d is com-
`municated to discovery engine 16. A particular set of dis(cid:173)
`covery agents may be installed on client 10 by the manu(cid:173)
`facturer as part of the manufacturing process. Additional
`discovery agents can be downloaded or otherwise installed
`on the client in the future to perform additional data collec-
`tion operations. Similarly, additional discovery rules can be
`installed on the client in the future to perform additional
`analysis.
`Client 10 also contains multiple discovery rules 18a, 18b,
`18c, and 18d. Although four discovery rules are illustrated in
`FIG. 1, a particular client 10 may include any number of
`discovery rules. Additionally, the number of discovery rules
`need not correspond to the number of discovery agents. As
`discussed above, the discovery rules and the discovery
`agents are independent of one another. Discovery engine 16
`40 receives data collected from one or more discovery agents
`14a-14d and uses the received data to execute one or more
`discovery rules 18a-18d. A particular discovery rule may
`require one or more data elements retrieved from one or
`more discovery agents 14a-14d. As discussed below, a
`discovery rule may compare the collected data to a prede(cid:173)
`termined value or threshold value, or may compare one
`collected data value to another collected value. A particular
`discovery rule may contain Boolean expressions, math(cid:173)
`ematical equations or other data operation or data com pari-
`50 son. The result of a particular discovery rule may store the
`received data, invoke another discovery rule, or combine the
`received data with previously stored data (e.g., performing
`data averaging). An exemplary discovery rule is provided

`Additionally, the result of a particular discovery rule may
`trigger one or more activities or events. For example, a
`65 particular discovery rule may generate a warning to the user
`of client 10 if the available disk space or available memory
`falls below a particular threshold. In this situation, the

`discovery rule will receive collected data regarding the
`available disk space and the available memory in client 10.
`That data is initially collected by discovery engine 16 from
`one or more discovery agents 14a-14d. The discovery rule
`then compares the collected data to its predetermined thresh-
`olds. If the available disk space or the available memory
`falls below the predetermined threshold, then a warning is
`generated and displayed or otherwise provided to the user of
`client 10. If the available disk space and the available
`memory are above the predetermined threshold, then the rule 10
`may complete execution without causing the occurrence of
`any particular activity or operation.
`Client 10 also includes a storage mechanism 20 coupled
`to discovery engine 16. Storage mechanism 20 can be used
`to store various tables and other configuration information 15
`used by discovery engine 16 during its regular operation.
`Additionally, storage mechanism 20 may store data gener(cid:173)
`ated during execution of one or more discovery rules.
`Client 10 is coupled to server 12 using a communication
`link 22. Communication link 22 can be any type of com- 20
`munication link using any type of communication medium.
`In a particular embodiment of the invention, client 10 and
`server 12 are coupled to one another across a network, such
`a local area network (LAN), a wide area network (WAN), or
`the Internet. Server 12 includes one or more discovery 25
`agents 24, one or more discovery rules 26, and a storage
`mechanism 28. Although server 12 contains discovery
`agents 24 and discovery rules 26, the server does not
`necessarily activate the discovery agents or execute the
`discovery rules. Instead, the server stores various discovery 30
`agents 24 and discovery rules 26 for transmission to one or
`more clients, which are then activated or executed by the
`discovery engine contained in the client.
`Storage device 28 in server 12 can be used to store various
`information regarding the clients coupled to the server and 35
`the various discovery rules and discovery agents already
`installed on each client. In a particular embodiment of the
`invention, storage device 28 also maintains the particular
`version of each discovery agent and discovery rule installed
`on each client. A typical server 12 is coupled to multiple 40
`clients 10. Although multiple clients 10 may be coupled to
`server 12, only particular clients may contain discovery
`agents, discovery rules and a discovery engine for coordi(cid:173)
`nating the collection of data. Any number of clients 10
`coupled to server 12 may be capable of implementing the 45
`information collection system of the present invention. A
`particular client 10 may be coupled to multiple servers 12
`and may receive discovery agents and discovery rules from
`multiple servers.
`FIG. 1 illustrates a particular embodiment of a client 50
`capable of implementing an information collection system
`as described herein. Similarly, server 12 is one embodiment
`of a server capable of distributing discovery agents and
`discovery rules to one or more clients. Particular compo(cid:173)
`nents of client 10 and server 12 are not shown in FIG. 1, for 55
`purposes of simplifying the illustration. For example,
`processors, memory devices, printing devices, and other
`components and devices commonly used in computer
`devices are not shown in FIG. 1. However, those of ordinary
`skill in the art will appreciate that these additional campo- 60
`nents can be added to client 10 or server 12 without affecting
`the operation of the invention.
`FIG. 2 illustrates an embodiment of a discovery engine 16
`that receives data collected by one or more discovery agents
`and applies the collected data to one or more discovery rules. 65
`Discovery engine 16 includes a table of discovery agents 40,
`which contains information about the various discovery
`
`6
`agents contained in the client. Table 40 includes, for
`example, the name (or other unique identifier) of the dis(cid:173)
`covery agent, the data collected by the discovery agent when
`the agent is activated, and the typical time interval between
`activations of the discovery agent. An exemplary table of
`discovery agents 40 is illustrated in FIG. 3, and discussed
`below.
`Discovery engine 16 also includes a table of discovery
`rules 42. Table 42 contains the name (or other unique
`identifier) of each discovery rule contained in the client, and
`information regarding the data required to execute each
`discovery rule. As discussed above, a particular discovery
`rule may require one or more data elements, which are
`collected by one or more discovery agents. An exemplary
`table of discovery rules 42 is illustrated in FIG. 4, and
`discussed below.
`Discovery engine 16 also includes a scheduler module 44.
`Particular discovery agents may require activation and peri(cid:173)
`odic time intervals (e.g., activated once every two seconds
`or once every minute). Scheduler module 44 maintains the
`information regarding the periodic activation of the discov(cid:173)
`ery agents contained in the client. The scheduler module
`may maintain its own table or register of information
`regarding the next activation of each discovery agent, or that
`information may be stored in the table of discovery agents
`40. When a particular discovery agent is scheduled to be
`activated, scheduler module 44 causes a discovery agent
`activation module 46 to perform the steps necessary to
`activate the discovery agent. Additionally, discovery agent
`activation module 46 may receive requests to activate a
`particular discovery agent from an external source (such as
`an activity or an event) other than the expiration of a time
`interval. These external activities or events may be received
`from another device coupled to a common network.
`Additionally, the external activities or events can be gener(cid:173)
`ated by the local system (i.e., the device implementing the
`information collection system). Module 46 is able to deter(cid:173)
`mine whether or not a particular discovery agent should be
`activated when an activation signal is received from sched(cid:173)
`uler module 44 or another event.
`In certain situations, the scheduler module 44 or other
`event may indicate that a discovery agent should be acti(cid:173)
`vated. However, discovery agent activation module 46 may
`override the activation request based on other factors. For
`example, the data collected by a particular discovery agent
`may not be required by any currently active discovery rule.
`In this situation, although a discovery agent may be sched(cid:173)
`uled to be activated, any data collected by the discovery
`agent would not be used. Therefore, the activation of the
`discovery agent is unnecessary, and module 46 prevents the
`activation of the discovery agent.
