`
`
`
`UNITED STATES PATENT AND TRADEMARK OFFICE
`
`BEFORE THE PATENT TRIAL AND APPEAL BOARD
`
`TWI PHARMACEUTICALS INC.,
`Petitioner,
`v.
`MERCK SERONO SA,
`Patent Owner.
`
`IPR2023-00050 (Patent 8,377,903 B2)
`
`Before ULRIKE W. JENKS, ZHENYU YANG and TINA HULSE,
`Administrative Patent Judges.
`
`PETITIONER’S NOTICE OF FILING UNDER SEAL
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`Petitioner TWi Pharmaceuticals Inc. (“Petitioner”) hereby respectfully
`
`submits this Notice of Filing Under Seal for Exhibit 1041 and portions of Petitioner’s
`
`Reply which reference exhibits for which Patent Owner has previously submitted its
`
`Motion to Seal.
`
`Also submitted with this filing is a redacted version of Exhibit 1045, of which
`
`the sealed, unredacted version was previously filed in support of Petitioner’s Motion
`
`for Additional Discovery.
`
`Exhibit 1041 is a transcript of the deposition of Patent Owner’s witness in a
`
`district court matter, which Patent Owner has designated as confidential and
`
`requested be filed under seal.
`
`Petitioner’s Reply also references, on pages 3-5, Exhibits 1043, 1044, 1045,
`
`2049, and 2050, for which Patent Owner has previously filed a Motion to Seal.
`
`Petitioner opposed the Motion to Seal, which is still pending.
`
`Pursuant to 37 C.F.R. § 42.14, “[a] party intending a document or thing to be
`
`sealed shall file a motion to seal concurrent with the filing of the document or thing
`
`to be sealed.” In this instance, it is Patent Owner who contends the exhibits at issue
`
`should be maintained under seal. Accordingly, to comply with its obligations under
`
`the Default Protective Order, and in an abundance of caution, Petitioner is filing
`
`these materials under seal.
`
`– 1 –
`
`
`
`While Petitioner does not believe the exhibits are in fact confidential,
`
`Petitioner understands it is Patent Owner’s burden as the party that designated the
`
`material as confidential to set forth the reasons why the material is confidential and
`
`should not be made available to the public. Appendix B to Patent Trial and Appeal
`
`Board Consolidated Trial Practice Guide (Nov. 2019) at § (d)(5)(A)(i).
`
`Petitioner will take a position regarding the sealing of the affected documents
`
`following the submission of Patent Owner’s reasons for confidentiality.
