`Re:
`
`Solas OLED Ltd. v. LG Display Co., Ltd., LG Electronics, Inc., & Sony
`Corporation, Case No. 6:19-cv-00236-ADA
`
`Dear Philip:
`
`Defendants LG Display Co., Ltd., LG Electronics, Inc., & Sony Corporation hereby
`stipulate that, if the Patent Trial and Appeal Board (“PTAB”) institutes the pending inter partes
`review petition in IPR2020-01055 challenging the patentability of claims 1, 9, 10, 11, 15, 36, 37,
`and 39 of U.S. Patent Number 7,907,137, then Defendants will not pursue the instituted
`invalidity grounds in the above-captioned litigation, 6:19-cv-00236.
`• For convenient reference, the proposed invalidity grounds in IPR2020-01055 are:
`Claims 1, 10, 11, 36 and 37 are unpatentable under 35 U.S.C. § 103 over
`Miyazawa (U.S. Appl. Publ. No. 2005/0116902), alone or with Childs (Int’l Pat.
`Publ. No. WO 2005/069267).
`• Claims 9, 15 and 39 are unpatentable under 35 U.S.C. § 103 over Miyazawa,
`alone or with Childs, and Kasai (U.S. Appl. Pub. No. 2005/0156837).
`
`To avoid any doubt, if the PTAB declines institution of IPR2020-01055, Defendants
`reserve the right to pursue these invalidity grounds in the parallel litigation.
`
`Best Regards,
`
