`Case IPR 2016-01567 for
`U.S. Patent No. 5,894,441
`
`Patent Owner Limestone Memory Systems LLC (“Limestone”) hereby files
`
`its Mandatory Notices pursuant to 37 C.F.R. §42.8(a)(2) for the above-captioned
`
`proceeding.
`
`I.
`
`Real Parties-In-Interest Under 37 C.F.R. §42.8(b)(1)
`
`The real parties-in-interest are Limestone Memory Systems LLC and Acacia
`
`Research Group LLC.
`
`
`
`II. Related Matters Under 37 C.F.R. §42.8(b)(2)
`
`Patent Owner notes the following matters that may affect or be affected by a
`
`decision in this proceeding:
`
`A. Related Administrative Matters
`
`There are no U.S. patent applications that claim priority to U.S. Patent No.
`
`5,894,441 (“the ‘441 patent”), and the ‘441 patent does not claim priority from
`
`another U.S. patent or patent application. There are no pending U.S. patent
`
`applications related to the ‘441 patent.
`
`Petitioner Apple has filed two concurrent IPR petitions against patents
`
`owned by Limestone. The patents at issue in each of these concurrent proceedings
`
`are unrelated except by their common assignment to Limestone and by having
`
`been asserted in lawsuits involving Limestone and Petitioner. In addition to the
`
`current matter, these matters include the following case numbers and patents:
`
`
`
`1
`
`

`
`Case IPR 2016-01567 for
`U.S. Patent No. 5,894,441
`
`
`Patent No.
`U.S. Patent No. 6,233,181 (“the ‘181 patent”)
`U.S. Patent No. 5,894,441 (“the ‘441 patent”)
`
`Case No.
`IPR 2016-01561
`IPR 2016-01567
`
`
`The ‘441 patent was subject of a prior IPR petition, filed by Micron
`
`Technology, Inc. (“Micron”) on October 27, 2015 as IPR2016-00094. That Micron
`
`petition was one of five concurrent IPR petitions filed against patents owned by
`
`Limestone, which are similarly unrelated except by their common assignment to
`
`Limestone and by having been asserted in lawsuits involving Limestone and
`
`Micron.
`
`Case No.

`IPR 2016-00095
`IPR 2016-00096
`IPR 2016-00097
`
`
`Patent No.
`U.S. Patent No. 5,805,504 (“the ‘504 patent”)
`U.S. Patent No. 5,894,441 (“the ‘441 patent”)
`U.S. Patent No. 5,943,260 (“the ‘260 patent”)
`U.S. Patent No. 6,233,181 (“the ‘181 patent”)
`U.S. Patent No. 6,697,296 (“the ‘296 patent”)
`
`Limestone filed preliminary responses in which it disclaimed certain claims of the
`
`‘441 patent and the ‘296 patent. Upon review of Micron’s petitions and
`
`Limestone’s preliminary responses, the Board denied Micron’s petitions at least in
`
`part as to the ‘504 patent, the ‘441 patent, and the ‘181 patent. To avoid delay from
`
`inter partes review arising from Micron’s petitions, Limestone filed statutory
`
`disclaimers as to certain claims of the ‘260 patent, the ‘181 patent, and the ‘296
`
`
`
`2
`
`

`
`Case IPR 2016-01567 for
`U.S. Patent No. 5,894,441
`
`patent; which ultimately terminated inter partes review of these claims. Limestone
`
`continues to assert the remaining claims from the ‘504 patent, the ‘441 patent, and
`
`the ‘181 patent against Micron and other defendants, including Petitioner, in
`
`related District Court Litigation discussed below.
`
`With respect specifically to the ‘441 patent, Micron’s petition in IPR2016-
`
`00094 asserted two grounds of invalidity, as follows:
`
`Claims
`1–3, and 5
`
`3, and 6–15
`
`
`
`Alleged Grounds for Invalidity
`35 U.S.C. § 102(b) as anticipated by U.S. Patent No.
`5,270,975, to McAdams (“McAdams”),
`35 U.S.C. § 103 as obvious over McAdams in view
`of Japanese Patent Application No. H06-052696
`(“Minami”)
`
`In its preliminary response, Limestone disclaimed claims 1–3, and 5 of the ‘441
`
`patent. The Board subsequently denied Micron’s petition as to claims 6–15.
`
`Further, the Board denied Micron’s subsequent request for rehearing as to claims
`
`6–15.
`
`B. Related Judicial Matters
`
`The patent at issue in the current matter, U.S. Patent 5,894,441 (“the ‘441
`
`patent”), is asserted in the following pending lawsuits:
`
`
`
`3
`
`

`
`CV-00658 (filed April 23, 2015 C.D. Cal.) (asserts the ‘504, ‘441, ‘181, and

`
` Limestone Memory Systems LLC v. Apple, Inc., No. 8:15-CV-01274 (filed
`
`August 10, 2015 C.D. Cal.) (asserts the ‘504, ‘441, ‘181, and ‘296 patents).
`
`The Patent Owner has filed additional lawsuits, which assert some of the
`
`same patents that are subject of the five concurrent IPR petitions filed by the
`
`Petitioner (listed above). These lawsuits are unrelated to the current matter except
`
`to the extent they involve Limestone and certain accused products in the cases are
`
`manufactured by the Petitioner. The ‘441 patent is not asserted in these additional
`
`lawsuits:
`
` Limestone Memory Systems LLC v. PNY Technologies, Inc., No. 8:15-CV-
`
`00656 (filed April 23, 2015 C.D. Cal.) (asserts the ‘260 patent); and

` Limestone Memory Systems LLC v. Transcend
`
`Information,
`
`Inc.
`
`(California), No. 8:15-CV-00657 (filed April 23, 2015 C.D. Cal.) (asserts
`
`the ‘260 patent).
