`
`INTRODUCTION
`
`I, William T. Plummer, Ph.D. make this declaration on behalf of Ability
`
`Opto-Electronics Technology Co., Ltd. (“Ability”) in connection with Ability’s
`
`petition for inter partes review of U.S. Patent No. 8,988,796 (“’796 patent”)
`
`assigned to Largan Precision Co. Ltd.
`
`2.
`
`I make this declaration based on my personal knowledge. I am over the age
`
`of twenty-one and competent to make this declaration. The statements in this
`
`declaration include my opinions, and the bases for those opinions, regarding the
`
`’796 patent.
`
`3.
`
`I have been asked by Ability to provide my opinion as to whether certain
`
`claims of the ’796 patent were disclosed in certain prior art patents that predate the
`
`’796 patent. This declaration contains my opinions and explains how I arrived at
`
`those opinions.
`
`4.
`
`I am being compensated for my work on this matter at my standard hourly
`
`rate of $520 ($260 for travel). My compensation is in no way dependent on the
`
`outcome of this inter partes review. The opinions expressed in this declaration are
`
`my own.

`II. QUALIFICATIONS
`
`5.
`
`I have been the President of WTP Optics since 2002. WTP Optics provides
`
`consulting services relating to the design, engineering, and manufacture of camera
`
`optical systems.
`
`6.
`
`As set forth below, I have worked in, and taught college-level classes relating
`
`to, the field of optics and optical systems including camera optical systems for more
`
`than 40 years. A copy of my curriculum vitae, detailing my educational
`
`background, professional and teaching experience, patents, and publications is
`
`attached hereto as Appendix A.
`
`7.
`
`I received my B.A. degree in Physics and Mathematics from the Johns
`
`Hopkins University in 1960, and my Ph.D. in Physics from the Johns Hopkins
`
`University in 1965. From 1991 to the present, I have been appointed as Senior
`
`Lecturer in the Mechanical Engineering Department of the Massachusetts Institute
`
`of Technology, and have been a member of various Ph.D. dissertation committees at
`
`MIT from 2004 t
