`
`PLAINTIFF PROMPTU SYSTEMS CORPORATION’S DISCLOSURE OF ASSERTED
`
`CLAIMS AND PRELIMINARY INFRINGEMENT CONTENTIONS
`
`Plaintiff Promptu Systems Corporation (“Promptu”) serves its Disclosure of Asserted
`
`Claims and Preliminary Infringement Contentions (“Disclosure”) regarding Infringement of US.
`
`Patent No. 7,280,538 (“the ’538 Patent”), US. Patent No. 7,047,196 (“the ”196 Patent”), and
`
`US Patent No. RE44,326 (“the ’326 Patent”). Promptu’s Disclosure is based on its current
`
`knowledge, understanding, and beliefs. Discovery is in its early stages and Promptu has not yet
`
`completed its investigation, collection of information, or analysis of Defendants’ conduct
`
`relevant to the ’538 Patent, the ’196 Patent, and the ’326 Patent. Promptu reserves its right to
`
`amend, revise and/or supplement any part of this Disclosure and/or any accompanying exhibits
`
`in accordance with this Court’s Scheduling Order and/or Federal Rules of Civil Procedure, as
`
`additional documents and information become available and as discovery and investigation
`
`proceed. This Disclosure does not represent, and should not be understood as describing,
`
`Promptu’s position regarding the construction of any claim language in the Asserted Claims of
`
`the ”538 Patent, the ’196 Patent, and the ’326 Patent. Moreover, this Disclosure is made without
`
`Comcast - Exhibit 1017, page 1
`
`Comcast - Exhibit 1017, page 1
`
`

`

`prejudice to any position that Promptu may take with respect to claim construction and Promptu
`
`reserves the right to assert claim constructions different from what may be inferred from this
`
`Disclosure. Promptu further reserves the right to supplement this Disclosure (i) based on claim—
`
`construction positions taken by Defendants and/or (ii) following any claim-construction Order
`
`from this Court, and reserves the right to introduce and use such supplemental materials at trial.
`
`This document represents Promptu’s preliminary infringement contentions. Promptu will serve
`
`its final contentions within a reasonable time after the Court construes the terms and phrases the
`
`parties will propose in a later-served document.
`
`I.
`
`ASSERTED CLAIMS

`
`proceed.
`
`III.
`
`INFRINGEMENT CLAIM CHARTS
`
`Promptu provides the attached Exhibit A, Exhibit B, and Exhibit C, which includes
`
`detailed infringement claim charts. For each Asserted Claim, the charts identify specifically
`
`where each element of each Asserted Claim is found in the Accused Instrumentalities.

`

`

`IV.
`
`THEORIES OF INFRINGEMENT
`
`Promptu asserts that, in addition to direct infringement, Defendants indirectly infringe the
`
`Asserted Claims through contributory infringement and/or induced infringement.
`
`V.
`
`LITERAL AND EQUIVALENT INFRINGEMENT
`
`Promptu asserts that the Accused Instrumentalities literally infringe the Asserted Claims
`
`of the ’538 Patent, the ’196 Patent, and the ’326 Patent. T0 the extent that any of the Accused
`
`Instrumentalities do not literally infringe, Promptu asserts infringement under the doctrine of
`
`equivalents.

`No. 7,260,538 
` 
`[1] A method for providing voice 
`recognition processing at a cable

`cable television network, 
`comprising the steps of: 
`
`Initial Claim Charts Against Accused Instrumentalities 
`
` 
`
`Comcast performs the method for providing voice recognition processing at a head‐end unit for voice‐
`controlled set‐top boxes in a cable television network as per the claim elements below. 
`See, e.g., https://www.xfinity.com/support/cable‐tv/get‐to‐know‐xr11‐remote/ (“The voice remote 
`(XR11) from XFINITY is a remote control that allows XFINITY X1 customers to find what they want faster 
`by using voice commands to change channels, search for shows, get recommendations and more. 
`Customers can use their voice to quickly find their favorite content, tune to channels, search and control 
`their DVR.”) 
`See, e.g., http://corporate.comcast.com/comcast‐voices/comcast‐voice‐remote‐texas‐instruments 
`(“Adding voice requires you to compress the data, send it from the remote via RF to the set‐top box, and 
`then uncompress the data before passing it to the voice recognition engine.”) 
`See, e.g., http://www.ctvnorthsuburbs.org/content/franchise/NSCCFinalReport.pdf (“The headend is the 
`aggregation point for most signals that are transmitted to, and received from, subscribers in the NSCC 
`area, and indeed the entire Twin Cities area that is served by Comcast. From the headend, Comcast uses 
`fiber optic infrastructure to send signals to its hub location in Shoreview, MN. From the headend and 
`hub, Comcast uses fiber optic cable to send and receive signals to/from nodes located in neighborhoods, 
`throughout the NSCC area, where forward (or downstream) signals are transformed from light, on the 
`fiber optic infrastructure, to Radio Frequencies (RF) for insertion onto the coaxial cable infrastructure for 
`ultimate transmission and distribution to residents and businesses served by the particular node. 
`Forward (or downstream) services include all analog, standard definition (SD) digital and high definition 
`(HD) digital channels including Video‐On‐Demand (VOD) and 3DTV channels. Additionally, Internet data, 
`traveling from Comcast’s headend or hub to subscribers, and telephone or voice service to subscribers is 
`carried on the forward/downstream portion of the network. In addition, the nodes receive RF signals 
`from subscribers via the coaxial cable infrastructure which feeds these signals into the node. The node 
`converts these signals to light for transmission, via the fiber optic infrastructure, to Comcast’s headend 
`or hub. Some return signals include upstream data, ordering information for VOD and other video 
`services as well as telephone traffic.”)

`Claim Language from U.S. Patent 
`No. 7,260,538 
` 
`[1A] a television remote control 
`receiving user‐activated indication 
`of a voice command; 
`
` 
`In the figure above, the Comcast XR11 is a television remote control that receives a user‐activated 
`indication of a voice command when a user presses the Microphone button and speaks into the remote. 
`See https://www.xfinity.com/support/cable‐tv/get‐to‐know‐xr11‐remote/  
`See, e.g., https://www.xfinity.com/support/cable‐tv/xr11‐remote‐faqs/ (“How do I use voice control? 
`Press and hold the Microphone (Mic) button while speaking a command into the microphone located at 
`the top of the remote. Be sure to speak one to eight inches away from the microphone. Release the 
`Microphone (Mic) button when you have finished the command.”) 
`Comcast receives voice commands through a microphone within the XR11 remote. 
`See, e.g., https://www.xfinity.com/support/cable‐tv/xr11‐remote‐faqs/ (“How do I use voice control? 
`Press and hold the Microphone (Mic) button while speaking a command into the microphone located at

`The Comcast XR11 remote transmits voice signals to a set‐top box via at least RF. 
`See, e.g., http://corporate.comcast.com/news‐information/news‐feed/comcast‐introduces‐voice‐
`controlled‐tv‐remote (“From a technology perspective, the remote records sound from a microphone 
`when the Mic button is held down and then uses voice‐over‐RF4CE™ ZigBee® technology to compress 
`and transmit that recording over a low bandwidth link to the X1 platform.”)
