DETAILED ACTION
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 1-10 and 12-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Park (US 2022/0206625) in view of Jung (US 2018/0150168).
Regarding claim 1, Park discloses a method for increasing a touch response speed (para. 227), applied to an electronic device (fig. 1), wherein the electronic device comprises a touchscreen (see TSP in fig. 3), a touch chip (310, fig. 3B), and an application processor (320, fig. 3B), the touchscreen comprises a plurality of transmit channels (TE_TX in fig. 3B) and a plurality of receive channels (TE_RX in fig. 3B), and the method comprises:
scanning, by the touch chip, one transmit channel group to obtain a touch data set (para. 191), wherein a quantity of transmit channels comprised in the transmit channel group is less than a quantity of all transmit channels of the touchscreen (para. 192-193), and the touch data set comprises parameters of equivalent capacitances between all receive channels and currently scanned transmit channels (para. 193, 105, 120-121);
transmitting by the touch chip, the touch data set to the application processor (para. 193, 195), until all transmit channel groups are scanned (para. 196, 202); and
sequentially receiving, by the application processor, touch data sets corresponding to the transmit channel groups (see fig. 9 and para. 202-203), until the touch data sets corresponding to all the transmit channel groups are received, and then obtaining touch location information corresponding to a touch operation on the touchscreen (para. 103, 161, 217).
Park fails to disclose wherein scanning the next transmit channel group partially overlaps with a touch transmission period of the touch data set.
Jung discloses transmitting, by the touch chip, the touch data set to an application processor while scanning (see transmitting S30-1 while scanning S10-2 in fig. 6), by the touch chip a next transmit channel group (S10-2 in fig. 6) until all transmit channel groups are scanned (see Groups 1-3 in fig. 10), wherein the scanning the next transmit channel group (S10-2, fig. 6) and the transmitting the touch data set (S30-1, fig. 6) are performed in parallel such that a scanning period of the next transmit channel group at partially overlaps with the touch data transmission period of the touch data set (see fig. 6 wherein S30-1 and S10-2 partially overlap).
When the invention was made (pre-AIA ) or before the effective filing date of the claimed invention (AIA ), it would have been obvious to one of ordinary skill in the art to include the teachings of Jung in the device of Park. The motivation for doing so would have been to have the data transmitting and touch scanning to reduce noise (Jung; para. 123) a to reduce the amount of time to determine a touch (Jung; para. 124). Ultimately to determine touch input puts more accurately and more efficiently.
