`
`Headwater Research LLC v. Samsung Electronics Co., Ltd. et al., Case No. 2:23-cv-
`00103 (E.D. Tex.)
`
`
`Dear Counsel:
`
`Samsung Electronics Co., Ltd. (“Samsung”) has filed an inter partes review (IPR) petition
`(IPR2024-00010) with the Patent Trial and Appeal Board (PTAB) to address the validity of
`claims 1-9, 11-13, and 15 of U.S. Patent No. 9,615,192 (“the ’192 Patent”). The tables in
`attached Appendix A list all grounds, challenged claims, and references asserted in IPR2024-
`00010.
`
` I
`
` write to inform you that Samsung hereby stipulates that, if the PTAB institutes IPR2024-00010,
`Samsung agrees not to pursue any grounds raised in the IPR, any grounds raised within
`Samsung’s invalidity contentions that were raised or could have been raised in the IPR, or any
`grounds Samsung could have reasonably raised before the PTAB, in this district court litigation
`or any parallel proceeding. Sotera Wireless, Inc. v. Masimo Corp., Case IPR2020-01019, Paper
`12 (PTAB Dec. 1, 2020). Samsung reserves the right to assert in the District Court proceedings
`prior art that is not eligible for PTAB consideration, e.g., the system art noted in Appendix B
`below and the system art identified in Samsung’s invalidity contentions.1 Samsung’s reservation
`is consistent with a Sotera stipulation because the grounds listed in Appendix B are based on
`prior art that is ineligible for consideration before the PTAB, and that could not have been raised
`before the PTAB.
`
`
`
`1 Samsung notes that discovery in the District Court proceedings is currently ongoing and
`Samsung expects Google, Apple, Blackberry, OpenWave, Nokia, and Microsoft to produce
`additional materials and/or testimony relating to the system art listed in Appendix B below. For
`the avoidance of doubt, Samsung reserves the right to rely on such forthcoming productions in
`the District Court proceedings.

`
`For the sake of clarity and to avoid any doubt, if the PTAB declines to institute IPR2024-00010,
`Samsung reserves the right to assert any grounds of invalidity in the District Court proceedings
`against the ’192 Patent.
`
