`
`I am a partner with the law firm of Gemini Law LLP.
`
`I am an experienced litigation attorney. I have been practicing law
`
`since 2012 and have extensive experience litigating patent infringement cases in
`
`many different courts across the United States.
`
`5. My experience in patent litigation matters includes patent bench trials,
`
`patent summary judgment proceedings, and other patent-related hearings and
`
`pleadings concerning, inter alia, patent validity and infringement issues. I have
`
`also represented clients’ appeals before the Court of Appeals for the Federal
`
`Circuit resulting from cases I tried and in other cases.
`
`6.
`
`I have an established familiarity with the subject matter at issue in this
`
`proceeding. I have reviewed the Petition and accompanying exhibits filed in this
`
`proceeding and all other papers associated with this proceeding, and have studied
`
`the ’069 patent. I am additionally involved in IPR2022-00258, pertaining to
`
`related subject matter.
`
`7.
`
`I am a member in good standing of the Bar of the State of New York
`
`2
`
`
`
`and am admitted to practice before the United States District Courts for the
`
`Southern District of New York and the Eastern District of New York, and the
`
`United States Court of Appeals for the Second and Federal Circuits.
`
`8.
`
`I have never been suspended or disbarred from practice before any
`
`court or administrative body.
`
`9. No application of mine for admission to practice before any court or
`
`administrative body has ever been denied.
`
`10.
`
` No sanctions or contempt citations have been imposed against me by
`
`any court or administrative body.
`
`11.
`
` I have read and will comply with the Office Patent Trial Practice
`
`Guide and the Board’s Rules of Practice for Trials set forth in part 42 of 37
`
`C.F.R.
`
`12.
`
` I understand that I will be subject to the USPTO Code of Professional
`
`Conduct set forth in 37 C.F.R.§§ 11.101 et seq. and disciplinary jurisdiction under
`
`37 C.F.R. §11.19(a).
`
`13.
`
`I have not applied to appear pro hac vice before the Office in the last
`
`three years.
`
`3
`
`
`
`I hereby declare under penalty of perjury under the laws of the United States of
`
`America that the foregoing is true and correct to the best of my knowledge.
