U.S. Patent No. 8,253,706 (“’706 Patent”)

Exemplary Accused Products

Renesas products, including at least each of the following products (and their variations) infringe at least Claim 1 of the ’706

Patent: Renesas RX microcontrollers with capacitive touch, such as RX113, RX231, RX230, and RX130. The infringement chart 

below is based on the RX113 microcontroller (“RX113 MCU”), which is exemplary of the infringement of the ’706 Patent.

Claim RX113 MCU

[1pre] A method comprising: The RX113 MCU provides capacitive touch sensing functionality, including in noisy 

and moist environments.

For example, the RX113 MCU controlled touch sensor may exhibit noise sources 

impacting signal to noise (SNR) parameters. RX113 MCU utilizes multiple 

measurements to filter effects of the noise sources.

[1a] acquiring a first response from an 

output line of a matrix touch screen, the 

first response being a capacitively 

induced signal derived from a rising edge 

of a pulse applied to an input line of the 

matrix touch screen;

The RX113 MCU acquires a first response from an output line of a matrix touch screen, 

the first response being a capacitively induced signal derived from a rising edge of a 

pulse applied to an input line of the matrix touch screen.

For example, the RX113 MCU controlled touch sensor acquires a first signal from the 

matrix touch sensor during the rising edge of the conversion clock.

The RX113 MCU acquires a second response from the output line of the matrix touch 

screen, the second response being a capacitively induced signal derived from a falling 

edge of the pulse applied to the input line of the matrix touch screen.

of the matrix touch screen; and

For example, the RX113 MCU acquires a second signal during the falling edge of 

conversion clock.

[1c] manipulating the first response and 

the second response to reject noise at 

frequencies less than a frequency 

associated with the pulse.

The RX113 MCU manipulates the first response and the second response to reject noise 

at frequencies less than a frequency associated with the pulse.

For example, the RX113 MCU manipulates current (noised) measurements which 

include the first and second responses to reject noise having low or at the touch sensor’s 

operational frequency.
