`
`I, Philip Ou, hereby declare as follows:
`1.
`I am a partner with the law firm Paul Hastings LLP, counsel for the Plaintiff Applied
`Materials, Inc. (“Applied”) in the above captioned matter. I am counsel for Applied’s customers,
`Intel and Samsung, in Demaray’s lawsuits against them in the Western District of Texas. I have
`personal knowledge of the facts contained in the declaration and, if called upon to do so, I could
`and would testify competently to the matters set forth herein. I submit this declaration in support
`of Applied’s Opposition To Demaray LLC’s Motion To Enlarge Time To Respond.
`2.
`In Demaray’s lawsuits against Intel and Samsung, Demaray has alleged that the
`claim required “narrow band rejection filter” can “be located in match circuits, combiners boxes,
`the power source hosing, cables or cable connects, among other locations that are coupled between
`the pulsed DC power supply and the target area” and identified components in certain PVD
`chambers not even in this location (e.g., an RF match connected to the substrate). An example of
`these contentions can be found at Dkt. No. 37-12, Sealed Exhibit C at pgs. 29-30 (Demaray’s
`February 5, 2021 supplemental infringement contentions to Intel for the ’276 patent.) Demaray has
`maintained substantially similar allegations in multiple supplementations to its infringement
`contentions in Texas, including as recently as this month.
`3.
`On January 7, 2022, Applied produced a bill of materials for its PVD chamber types
`having a DC power supply connected to the target and RF bias supply connected to the substrate,
`which Demaray agreed to as the configurations it sought in discovery for Applied’s declaratory
`judgment claims of non-infringement. Applied did not limit this production to PVD chambers sold
`to Intel and Samsung or only ones accused in the Texas customer suits. On March 7, 2022, counsel
`for Demaray sent correspondence to me asking to confirm that the document produced was a
`complete list of those PVD chambers. I responded with confirmation.
`I declare under penalty of perjury that the foregoing is true and correct.
