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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 5-8 and 17-20 are rejected under 35 U.S.C. 103 as being unpatentable over US 2015/0102685 by Blood et al. (Blood hereinafter) in view of US 2013/0134794 by Lee et al. (Lee hereinafter). Regarding claim 5, Blood discloses the wireless power transmitter of claim 1. Blood fails to disclose wherein the first transmitter antenna comprises: a first antenna portion; and a second antenna portion, and wherein the second transmitter antenna comprises: a third antenna portion; and a fourth antenna portion.

It would have been obvious to a person of ordinary skill in the art before the effective filing date of the Applicant's invention to utilize a multi-portion antenna/coil for wireless power transfer in order to increase efficiency of power transferred to a receiver. Thus, increasing power to the receiver and decreasing energy waste. Regarding claim 6, Blood in view of Lee teaches the wireless power transmitter of claim 5. Lee discloses wherein the first antenna portion comprises one or more first outer turns, wherein the second antenna portion comprises one or more first inner turns that are radially inward from the one or more first outer turns, wherein the third antenna portion comprises one or more second outer turns, and wherein the fourth antenna portion comprises one or more second inner turns that are radially inward from the one or more second outer turns [see at least Figure 5, (421); inner loop and outer loop]. Regarding claim 7, Blood in view of Lee teaches the wireless power transmitter of claim 6. Blood discloses wherein the first antenna portion is in wired electrical connection with (i) the second antenna portion and (ii) the power conditioning system [see at least Figure 11, (32) and (34)], and wherein the third antenna portion is (i) in wireless electrical connection with one or both of the first or second antenna portions and (ii) is in wired electrical connection with the fourth antenna portion [see at least Figure 11, (42) and (41)]. Regarding claim 8, Blood in view of Lee teaches the wireless power transmitter of claim 5. Blood discloses the coupling of the antennas to the circuit and each other. Lee discloses wherein the first antenna portion includes a first terminal and a second terminal, wherein the second antenna portion includes a third terminal and a fourth terminal, wherein the second terminal is in electrical connection with the third terminal of the second antenna portion, wherein each of the first antenna portion and the second antenna portion is configured to couple with one or more other transmitter antennas, receiver antennas, or combinations thereof, wherein the third antenna portion includes a fifth terminal and a sixth terminal, wherein the fourth antenna portion includes a seventh terminal and an eighth terminal, wherein the sixth terminal of the third antenna portion is in electrical connection with the seventh terminal of the fourth antenna portion, wherein each of the third antenna portion and the fourth antenna portion is configured to couple with one or more receiver antennas [see at least Figure 5, (421); considered terminals at the connecting points of the antenna to the transmitter and the inner loop to the outer loop]. Regarding claim 17, Blood discloses the antenna of claim 16. Blood fails to disclose wherein the first transmitter antenna comprises: a first antenna portion; and a second antenna portion, and wherein the second transmitter antenna comprises: a third antenna portion; and a fourth antenna portion. However, Lee discloses this limitation [see at least Figure 5, (421); inner loop and outer loop]. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the Applicant's invention to utilize a multi-portion antenna/coil for wireless power transfer in order to increase efficiency of power transferred to a receiver. Thus, increasing power to the receiver and decreasing energy waste. Regarding claim 18, Blood in view of Lee teaches the antenna of claim 17. Lee discloses wherein the first antenna portion comprises one or more first outer turns, wherein the second antenna portion comprises one or more first inner turns that are radially inward from the one or more first outer turns, wherein the third antenna portion comprises one or more second outer turns, and wherein the fourth antenna portion comprises one or more second inner turns that are radially inward from the one or more second outer turns [see at least Figure 5, (421); inner loop and outer loop].

Regarding claim 20, Blood in view of Lee teaches the antenna of claim 17. Blood discloses further comprising transmitter tuning system that is (i) in electrical connection with first and second terminals of the second transmitter antenna and (ii) not in electrical connection with the power conditioning system [see at least Figure 11, (41)]. Claims 10-12 are rejected under 35 U.S.C. 103 as being unpatentable over US 2015/0102685 by Blood et al. (Blood hereinafter) in view of US 2009/0284220 by Toncich et al. (Toncich hereinafter). Regarding claim 10, Blood discloses the wireless power transfer system of claim 9. Blood fails to disclose wherein the wireless power receiver is configured to (i) electrically connect with a computer peripheral and (ii) provide power to the load associated with the wireless power receiver, and wherein the load is a load of the computer peripheral. However, Toncich discloses this limitation [see at least Figure 17A, (730A); Table 3, “Mouse with a low battery”]. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the Applicant's invention to provide power to a computer peripheral device as it is a commonly used item that is generally wired. Thus, allowing for the elimination of a wire and allow more free movement of the device. Regarding claim 11, Blood in view of Toncich teaches the wireless power transfer system of claim 10. Toncich discloses wherein the computer peripheral is a computer mouse [see at least Figure 17A, (730A); Table 3, “Mouse with a low battery”].
