`Ex. 1068, p. 1

`
`Declaration of Kushan
`
`I, Jeffrey P. Kushan, make the following Declaration pursuant to 28 U.S.C.
`
`§ 1746:
`
`1.
`
`2.
`
`I am a partner at the law firm of Sidley Austin LLP.
`
`I provide this declaration in connection with the above-identified post
`
`grant review proceeding before the United States Patent and Trademark Office and
`
`initiated by Merck Sharp & Dohme LLC (“Merck”) against Halozyme Inc. under
`
`35 U.S.C. § 321. Unless otherwise stated, the facts stated in this Declaration are
`
`based on my personal knowledge.
`
`3.
`
`For each of the exhibits addressed below, an exhibit label and page
`
`numbers have been added, but no other alterations have been made. Where the
`
`exhibit is a PDF generated from a webpage displayed in a web browser, the PDF
`
`may contain information in the header and footer (e.g., the URL, the title of the
`
`page being displayed, or similar items), which was generated automatically by the
`
`web browser displaying the page.
`
`4.
`
`EX1015 is a document mapping citations in Merck’s Petition to U.S.
`
`Patent No. 12,110,520 (“the ’520 Patent”) to corresponding text in U.S. Patent
`
`Application No. 13/694,731 (“the ’731 Application”). This mapping was prepared
`
`by staff at my law firm working under my supervision, and is true and accurate to
`
`the best of my knowledge.

`5.
`
`Exhibit 1016 is a true and correct copy of a publication by Boris
`
`Steipe titled “Consensus-Based Engineering of Protein Stability: From Intrabodies
`
`to Thermostable Enzymes” (“Steipe”). This paper was published as a chapter in
`
`“Methods in Enzymology,” Vol. 388, on pages 176-186. As the Steipe paper itself
`
`does not include the year in which it was published, I have appended the
`
`publication information at the end of Exhibit 1016, as pages 187-192. Pages 187-
`
`192 of Exhibit 1016 are a true and correct copy of the web page available from the
`
`following URL:
`
`https://www.sciencedirect.com/science/article/abs/pii/S0076687904880169
`
`6.
`
`Exhibit 1045 is a true and correct copy of a redline that I had created
`
`for U.S. Patent Application No. 13/694,731 and U.S. Patent No. 12,110,520 using
`
`Litera Compare in Microsoft Word. To create this redline, the text of U.S. Patent
`
`Application No. 13/694,731 (as published in U.S. Patent Application Publication
`
`2013-0302275) was copied and compared to the text of U.S. Patent No.
`
`12,110,520, both obtained from the USPTO’s Patent Center website. The text of
`
`both documents was pasted into separate Word documents. Any text that appeared
`
`before the “Background/Summary” heading and the claim language was deleted.
`
`The Word document with the text from U.S. Patent Application No. 13/694,731
`
`was designated as the original file and the Word document with the text from U.S.
`
`Patent No. 12,110,520 was designated as the modified file. I saved the redline as a
`
`Petitioner Merck
`Ex. 1068, p. 3
`
`
`
`PGR2025-00017
`
`Declaration of Kushan
`
`PDF and included it here as Exhibit 1045. The redline shows certain differences as
`
`a result of formatting changes (principally in the presentation of tables). In my
`
`review of the redline (with one exception1), I have not identified any substantive
`
`differences between U.S. Patent Application No. 13/694,731 and U.S. Patent No.
`
`12,110,520, and I believe them to be substantively identical.

`The ’520 Patent alters the list of mutations that should be avoided in

`
`enzymatically active PH20 proteins by removing positions 282, 298, and
`
`431 from the list in the ’731 Application. See EX1045, 78; also EX1001,
