DETAILED ACTION
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
RESPONSE TO AMENDMENT
Claim rejections based on prior arts
Applicant's arguments filed on 12/30/2025 with respect to claims 1-20 have been fully considered but are not persuasive.
With respect to claim limitation “wherein the Rx.Detect procedure and the identification of the orientation and the configuration lane are performed without a power delivery (PD) controller or a type-C port controller (TCPC)”, see fig. 2 of Sugumar, which doesn’t specifically disclose a ‘power delivery (PD) controller’. Note, a negative limitation such as this can be confusing because the performances can be done without a lot of things, close to an infinite number of things. Also, a location of a power delivery (PD) controller or a type-C port controller (TCPC) being part of the host, system is not recited. Claim limitation “wherein the Rx.Detect procedure and the identification of the orientation and the configuration lane are performed without a power delivery (PD) controller or a type-C port controller (TCPC)” is also confusing because the claim doesn’t previously disclose ‘performing’ a configuration lane.
Note, even though prosecution is now closed, to help expedite any further potential prosecution of this application, Applicant is encouraged to contact the Examiner to discuss the invention, and a potential allowance.
OBJECTIONS TO THE CLAIMS
Claims 1-20 are objected to as being indefinite for failing to particularly point out and distinctly claim the subject matter which applicant regards as the invention.
As per claim 1, claim limitation “wherein the Rx.Detect procedure and the identification of the orientation and the configuration lane are performed without a power delivery (PD) controller or a type-C port controller (TCPC)” is confusing because the claim doesn’t previously disclose ‘performing’ a configuration lane. Claims 9 and 17 have the same problem. Correction is needed.
Claim 20 is objected to because of the following informalities:
As per claim 20, ‘an procedure’ in line 3 seems to be typo. Correction is needed
REJECTIONS BASED ON PRIOR ART
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
1. Claims 1, 2, 4-11 and 13-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Sugumar et al. (US pub. # 2019/0236037), hereinafter, “Sugumar”.
At the outset, Applicant is reminded that claims subject to examination will be given their broadest reasonable interpretation in light of the supporting disclosure. In re Morris, 127 F.3d 1048, 1054-55, 44 USPQ2d 1023,1027-28 (Fed. Cir. 1997). With this in mind, the discussion will focus on how the terms and relationships between the terms in the claims are met by the references.
2. As per claim 1, Sugumar discloses a universal serial bus (USB) host (computing device 201 of fig. 2) comprising: a USB port (USB Type-C interface 236) to couple with a USB device (a USB PD source, as discloses in paragraph 0072) by a USB cable and communicate with the USB device in accordance with a USB protocol (see fig. 2 and paragraphs 0019 and 0022); and a USB host controller (PMIC 204 of fig. 3) communicatively coupled with the USB port by a first data lane and a second data lane [see paragraph 0044, which discloses “If a USB 2.0 device is coupled to a USB-C adapter or cable that is inserted, then only the USB 2.0 signals are used, which include D+ and D− data signals (one of the two USB 2.0 D+/D− signal pair will be connected, depending on the orientation). The presence of a USB 2.0 device will be detected by USB 2.0 detection block 304, which also is used to provide communication with TCPC 214a and charger controller 212”], wherein the USB host controller is to: perform
a far-end receiver termination detection (Rx.Detect) (note, ‘a far-end receiver termination detection (Rx.Detect)’ is not a well-known term in the art) procedure on both of the first and second data lanes (see paragraph 0044, which teaches detection of connection on D+ and D- lanes, the function called by ‘Rx.Detect’); identify that the Rx.Detect procedure was successful on only one of the first and second data lanes (see paragraphs 0044 and 0089); identify, based on which of the first and second data lanes the Rx.Detect procedure was successful on, an orientation of a USB cable in the USB port (see paragraphs 0041, 0042 and 0067); and identify, based on the orientation, a configuration lane for communication with the USB device via the USB cable in accordance with the USB protocol (see paragraphs 0041 and 0042), wherein the Rx.Detect procedure and the identification of the orientation and the configuration lane are performed without a power delivery (PD) controller or a type-C port controller (TCPC) [see fig. 2, which doesn’t specifically disclose a ‘power delivery (PD) controller’. Note, a negative limitation such as this can be confusing because the performances can be done without a lot of things, close to an infinite number of things. Also, a location of a power delivery (PD) controller or a type-C port controller (TCPC) being part of the host, system is not recited].
3. As per claim 2, Sugumar discloses “The USB host of claim 1” [See rejection to claim 1 above], wherein the USB host controller is further to: identify, if the Rx.Detect procedure is successful on the first data lane, the first data lane as the configuration lane; and identify, if the Rx.Detect procedure is successful on the second data lane, the second data lane as the configuration lane (see paragraphs 0041, 0042 and 0067).
4. As per claims 4 and 13, Sugumar discloses wherein the USB port is a USB Type-C port (see paragraph 0036).
5. As per claims 5 and 14, Sugumar discloses wherein the USB host controller is further communicatively coupled with the USB port by at least two data lanes (see fig. 3).
6. As per claims 6 and 16, Sugumar discloses wherein the Rx.Detect procedure is performed without a power delivery (PD) controller (see paragraph 0040) or a type-C port controller (TCPC).
7. As per claim 7, Sugumar discloses wherein the USB host further includes a first communication channel (CC1) [first configuration channel (CC1)] and a second communication channel (CC2) [second configuration channel (CC2)] coupled with the USB port, wherein CC1 and CC2 are different from the first and second data lanes (see fig. 3).
8. As per claim 8, Sugumar discloses wherein the USB host controller is further to perform the Rx.Detect procedure subsequent to a reset procedure (see paragraph 0020).
9. As per claim 9, Sugumar discloses a universal serial bus (USB) host (computing device 201 of fig. 2) comprising: a USB port (USB Type-C interface 236) to couple with a USB device (a USB PD source, as discloses in paragraph 0072) by a USB cable and communicate with the USB device in accordance with a USB protocol (see fig. 2 and paragraphs 0019 and 0022); and a USB host controller (PMIC 204 of fig. 3); and a USB host controller (PMIC 204 of fig. 3) communicatively coupled with the USB port by a first configuration channel (CC1) [first configuration channel (CC1)] and a second communication channel (CC2) [second configuration channel (CC2)], wherein the USB host controller is to: identify a voltage change on one of CC1 or CC2 (see paragraphs 0041 and 0042), wherein the voltage change is based on the USB cable being plugged into the USB port (see paragraphs 0041 and 0042); identify, based on which of CC1 and CC2 the voltage change was identified on, an orientation of a USB cable in the USB port [see paragraph 0042, which discloses “a pinout diagram 320 shows the various signals of a USB-C interface (shown with pin numbers A1-A12 and B1-B12 in FIG. 2). The USB-C interface is symmetrical, enabling a USB-C cable connector to be inserted into a USB-C port in one of two orientations (referred to a “right-side up” or “upside down”). The orientation is detected by CC logic block 302 by measuring voltage levels for signals CC1 and CC2 for pins CC1 and CC2. The detection process is initiated in response to insertion of a USB-C cable or device plug, which will result in the VBUS voltage level detected by VBUS detection block 300 and voltage levels for CC1 and CC2 being detected by CC logic block 302. Prior to insertion of the USB-C cable or plug, the path depicted from battery charger 221 to the VBUS pin will be open. As a result, if the USB device is a DC power source, a positive VBUS voltage level produced by the USB power source will be detected. If the USB device is a sink, the detected VBUS voltage level will be ground”]; and identify, based on the orientation, a configuration lane for communication with the USB device via the USB cable in accordance with the USB protocol (see paragraph 0042), wherein the Rx.Detect procedure and the identification of the orientation and the configuration lane are performed without a power delivery (PD) controller or a type-C port controller (TCPC) [see fig. 2, which doesn’t specifically disclose a ‘power delivery (PD) controller’. Note, a negative limitation such as this can be confusing because the performances can be done without a lot of things, close to an infinite number of things. Also, a location of a power delivery (PD) controller or a type-C port controller (TCPC) being part of the host, system is not recited].
10. As per claim 10, Sugumar discloses wherein the voltage change is based on a voltage provided by the USB device to the USB cable (see paragraph 0043).
11. As per claim 11, Sugumar discloses wherein the USB host controller is further to identify, based which of CC1 and CC2 the voltage change was identified on, CC1 or CC2 as the configuration lane (see paragraphs 0042 and 0043).
12. As per claim 15, Sugumar discloses wherein: if the voltage change is identified on CC1, the USB host controller is to identify the first data lane as the configuration lane; and if the voltage change is identified on CC2, the USB host controller is to identify the second data lane as the configuration lane (see paragraphs 0041 and 0042).
13. As per claim 17, Sugumar discloses a universal serial bus (USB) system (architecture 200 of fig. 2) comprising: a USB port (USB Type-C interface 236) to couple with another electronic device (a USB PD source, as discloses in paragraph 0072) by a USB cable and communicate with the other electronic device in accordance with a USB protocol (see fig. 2 and paragraphs 0019 and 0022); and a USB dual-role controller (PMIC 204 of fig. 3) communicatively coupled with the USB port by a first data lane, a second data lane, a first communication channel (CC), and a second CC (see fig. 3), wherein the USB dual-role controller is to: identify, based on a previously input setting, whether the system is to act in accordance with a USB host functionality or a USB device functionality (see paragraph 0043); and alter one or more switches related to a Type-C state machine to enact the USB host functionality or the USB device functionality based on the previously input setting (see paragraph 0039), wherein the Rx.Detect procedure and the identification of the orientation and the configuration lane are performed without a power delivery (PD) controller or a type-C port controller (TCPC) [see fig. 2, which doesn’t specifically disclose a ‘power delivery (PD) controller’. Note, a negative limitation such as this can be confusing because the performances can be done without a lot of things, close to an infinite number of things. Also, a location of a power delivery (PD) controller or a type-C port controller (TCPC) being part of the host, system is not recited].
14. As per claim 18, Sugumar discloses wherein alteration of the switches changes to which of a device-related resistor and host-related resistor the first CC and the second CC are coupled (see fig. 3).
15. As per claim 19, Sugumar discloses wherein, if the system is to act in accordance with the USB host functionality, the USB dual-role controller is further to: identify a voltage change on one of the first CC or the second CC, wherein the voltage change is based on the USB cable being plugged into the USB port; identify, based on which of the first CC and the second CC the voltage change was identified on, an orientation of a USB cable in the USB port; and identify, based on the orientation, a configuration lane for communication with the USB device via the USB cable in accordance with the USB protocol (see paragraphs 0042 and 0043).
16. As per claim 20, Sugumar discloses wherein, if the system is to act in accordance with the USB host functionality, the USB host/device controller is further to: perform
a far-end receiver termination detection (Rx.Detect) an procedure on both of the first and second data lanes; identify that the Rx.Detect procedure was successful on only one of the first and second data lanes; identify, based on which of the first and second data lanes the Rx.Detect procedure was successful on, an orientation of a USB cable in the USB port; and identify, based on the orientation, a configuration lane for communication with the USB device via the USB cable in accordance with the USB protocol (see paragraphs 0042-0044).
Claim Rejections - 35 USC § 103
17. In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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.
18. Claims 3 and 12 are rejected under 35 U.S.C. 103(a) as being unpatentable over Sugumar et al. (US pub. # 2019/0236037), hereinafter, “Sugumar”, in view of Lin et al. (US pub. # 2020/0012614), hereinafter, “Lin”.
19. As per claims 3 and 12, Sugumar discloses “The USB host of claim 1” [See rejection to claim 1 above], but fails to expressly discloses wherein the USB protocol is a USB 3.2 protocol.
Lin discloses wherein the USB protocol is a USB 3.2 protocol (see paragraph 0027).
It would have been obvious to one having ordinary skills in the art before the effective filling date of the claimed invention to incorporate Lin’s teaching of adjusting a signal transmission direction in a cable that’s configured to be electrically coupled between a first interface port and a second interface port, into Sugumar’s teaching of a Power Management Integrated Circuit (PMIC) of a host device to perform various functions, such as battery management, voltage regulation, and charging functions, for the ability/benefit of having the USB Type-C plug connector and receptacle connector connected bi-directionally, introducing a dual-role capability.
