`
`
`I, Christopher Charles Johns, make the following declaration pursuant to 28
`
`U.S.C. § 1746.
`
`1.
`
`I am an attorney at the law firm Finnegan, Henderson, Farabow,

`
`I provide this Declaration in connection with the above-identified
`
`inter partes review proceeding. Unless otherwise stated, the facts stated in this

`
`3.
`
`On April 4, 2016, I visited
`
`http://www.sciencedirect.com/science/journal/09583947/27 and saved images of it.
`
`Those images are now Exhibit 1022, and refer to Tobler et al, “The application of
`
`dynamic field shaping and dynamic dose rate control in conformal rotational
`
`treatment of the prostate.” I also obtained a copy of Tobler et al, “The application
`
`of dynamic field shaping and dynamic dose rate control in conformal rotational
`
`treatment of the prostate,” which is now Exhibit 1027, by clicking on this link.
