`
`U.S. Patent No. 8,749,251 (“’251 Patent”) for Sony Products
`Exemplary Accused Products
`Sony products, including at least each of the laptop products listed in Sony’s Response to Neodron’s Interrogatory No. 1, infringe at
`least Claims 1, 2, 3, 5, 7, 8, 9, 16, 17, 18, and 20 of the ’251 Patent.
`
`Claim 1
`Claim 1
`
`[pre] An apparatus
`comprising:
`
`[a] a sensing element of
`a touch screen; and
`
`Sony products
`
`The preamble is not a limitation.
`
`Each Sony product comprises a sensing element of a touch screen.
`
`For example, the Xperia XZ3 includes a capacitive touch screen.

`
`
`
`[b] one or more
`computer-readable non-
`transitory storage media
`coupled to the sensing
`element and embodying
`logic that is operable
`
`Each Sony product includes one or more computer-readable non-transitory storage media coupled to the
`sensing element and embodying logic that is operable when executed to perform the claimed method.
`
`For example, the Xperia XZ3 includes one or more touch controllers or system processors with non-
`transitory storage (e.g. Flash, EEPROM, HDD, SDD, etc.) embodying logic executable to perform the
`

`
`
`
`Claim 1
`
`Sony products
`
`when executed to:
`
`steps described below.
`
`
`
`[c] determine an amount
`of time that has elapsed
`since the sensing
`element last detected a
`change of capacitance
`indicative of a key touch
`on the touch screen; and
`
`[d] if the amount of time
`that has elapsed exceeds
`a predetermined time
`duration, then initiate a
`particular function of the
`apparatus.
`
`Each Sony product contains executable logic to determine an amount of time that has elapsed since the
`sensing element last detected a change of capacitance indicative of a key touch on the touch screen.
`
`For example, touching the Xperia XZ3’s touch screen and then removing the touch, thereby causing a
`change of capacitance, can cause the Xperia XZ3 to respond in various ways after a delay, indicating that
`the Xperia XZ3 determines the amount of time elapsed since the touch sensor detected a touch.
`
`See, e.g., analysis and evidence of element 1[d] below.
`
`Each Sony product contains executable logic to, if the amount of time that has elapsed exceeds a
`predetermined time duration, then initiate a particular function of the apparatus.
`
`For example, the capacitive touch sensor in the Xperia XZ3 enters a different sensing mode a
`predetermined amount of time after a user’s finger is removed from the touch screen. This change is
`readily observable using a standard oscilloscope measuring the capacitive drive signals a short distance
`above the Xperia XZ3’s touch screen. There is a distinct difference between the drive signal observed
`while a finger touch is in contact with the drive signal observed after removing that touch. This difference
`likely reflects a power-saving mode initiated after the touch is removed. The change occurs after a
`consistent time offset.

`
`The apparatus of claim

`particular function
`comprises deactivation
`of measurement of
`changes in capacitance
`
`Sony products
`
`Each Sony product comprises an apparatus of claim 1. See, e.g., analysis and evidence of claim 1 above.
`
`For example, in the Xperia XZ3, the particular function comprises deactivation of measurement of changes
`in capacitance by the sensing element. For example, the capacitive touch sensor in the Xperia XZ3 ceases
`measuring capacitance changes for a period of time. For another example, the capacitive touch sensor in the
`Xperia XZ3 has a particular function wherein it measures changes in capacitance only during certain times

`comprises recalibration
`of measurement of
`changes in capacitance
`
`Sony products
`
`Each Sony product comprises an apparatus of claim 1. See, e.g., analysis and evidence of claim 1 above.
`
`For example, in the Xperia XZ3, the particular function comprises recalibration of measurement of changes
`in capacitance by the sensing element. For example, the capacitive touch sensor in the Xperia XZ3 uses a
`different drive signal when the particular function is initiated, which requires recalibrating the measurement
`of changes in capacitance.
