`
`Re: Nokia Corporation, et al. v. Amazon.com, Inc., et al., C.A. No. 23-cv-1236-GBW
`
`Dear Judge Williams:
`
`Per the Court’s Oral Order (D.I. 26), Plaintiffs identify the following cases as most similar to the
`patents at issue:
`
`For 6,950,469; 7,280,599; and 8,036,273, Nokia identifies Cal. Inst. of Tech. v. Broadcom Ltd.,
`25 F.4th 976, 988 (Fed. Cir. 2022) (U.S. Patent No. 7,916,781, Claim 13). Like in Cal. Inst. of
`Tech., these patents do not claim “mathematical formula[s] as such.” Id. Rather, the claims
`provide improved methods of interpolation in video coding.
`
`For 7,724,818 (cl. 1), Nokia identifies Packet Intelligence LLC v. NetScout Sys., 965 F.3d 1299,
`1309-10 (Fed. Cir. 2020). Even more concrete than the “granular, nuanced, and useful
`classification of network traffic” in Packet Intelligence, the ’818 Patent claims a granular,
`nuanced, and useful data structure: a hierarchical parameter set structure requiring sequence and
`picture parameter sets with at least one picture parameter value in the slice header. See also
`Enfish LLC v. Microsoft Corp., 822 F.3d 1327, 1339 (Fed. Cir. 2016) (“a specific type of data
`structure designed to improve the way a computer stores and retrieves data in memory” was not
`directed to an abstract idea).
`
`For 6,968,005 and 8,144,764, Nokia identifies Koninklijke KPN N.V. v. Gemalto M2M GmbH, 942
`F.3d 1143 (Fed. Cir. 2019). Like KPN, these patents provide an improvement upon conventional
`technology by including additional “check data” for error detection—here, an indicator to
`differentiate between missing reference and non-reference pictures. Id. at 1150. See also Enfish
`LLC v. Microsoft Corp., 822 F.3d 1327 (Fed. Cir. 2016) (“a specific type of data structure designed
`to improve the way a computer stores and retrieves data in memory” was not directed to an abstract
`idea).
