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

Exemplary Accused Product

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

Patent: Capsense enabled Cypress products, including MBR3, CY8CMBR2110, CY8CMBR2044, CY8CMBR2016, CY8CMBR2010,

CY8CMBR3XXX, and Capsense-enabled PSoC. The infringement chart below is based on the Cypress PSoC with CapSense

(“CapSense”), which is exemplary of the infringement of the ’706 Patent.

Claim CapSense 

[1pre] A method comprising: The CapSense touchcontroller provides capacitive touch sensing functionality, 

including in noisy and moist environments.

For example, a CapSense-enabled touch sensor may exhibit noise sources impacting 

signal to noise (SNR) parameters. CapSense utilizes capacitor raw capacitor charge 

counts to distinguish touch from noise.

[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 CapSense touchcontroller 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, CapSense-enabled touch sensor acquires a first signal from the matrix 

touch sensor during the rising edge of the switching clock.

[1b] acquiring 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; and

The CapSense touchcontroller 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. 

For example, CapSense senses the sourced current Ics sourced from the capacitor the 

sensor capacitor.

[1c] manipulating the first response and 

the second response to reject noise at 

frequencies less than a frequency 

associated with the pulse.

The CapSense touchcontroller manipulates the first response and the second response to 

reject noise at frequencies less than a frequency associated with the pulse. 

For example, CapSense manipulates the row count responses which include the first and 

second responses (i.e. IDAC sinking and sourcing mode responses) to reject noise 

having low or at the touch sensor’s operational frequency.
