`
`U.S. Patent No. 7,917,680 (“’680 Patent”)
`
`Accused Products
`Apple products including smartphones, tablets, and computers with Apple A-Series or M-Series SoCs (“Apple Ax/Mx
`System”) infringe at least Claim 1 of the ’680 Patent.
`
`Claim 1
`
`Claim 1
`1[pre]. A method for managing packet-
`based communications in a rules-based
`system, the method comprising:
`
`Apple Ax/Mx System
`To the extent the preamble is limiting, the Apple Ax/Mx System implements a method
`for managing packet-based communications in a rules-based system as claimed.
`For example, the Apple Ax/Mx System includes an ARM AMBA AXI3 or AXI4 or
`similar, such as a PL301 fabric implementing ordering rules, including without
`limitation an “Apple Fabric.”

`The Apple Ax/Mx System includes a packet processor that implements generating a
`protocol-based ordering configuration for passing packet data as a function of protocol
`compliance rules for the rules-based system.
`For example, the Apple Ax/Mx System orders AXI packet data communications
`according to rules set out in the AXI3, AXI4, PL301, and/or other related protocols.
