DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
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 (i.e., changing from AIA to pre-AIA ) 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.
Claims 1-4 & 6 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hayes et al. US Patent Application Publication 2022/0029291.
Regarding Claim 1, Hayes et al. teaches an antenna structure (Figs. 3-6), comprising:
a ground plane (300 Fig. 3 Par. 0042),
a radiator (310 Fig. 3 Par. 0042), being arranged and suspended above the ground plane (Fig. 3);
one or more reflectors (R2, R8, R6, R4 Fig. 3 Par. 0045), forming an angle with the radiator relative to the ground plane (Fig. 3) and being arranged at a distance around the periphery of the radiator (Fig. 3); and
one or more switch elements (410 Fig. 4 Par. 0047, 0048), being respectively arranged between the one or more reflectors and the ground plane to control the connection between the one or more reflectors and the ground plane (“The second switch assembly 410 may include switches that are controllable by the selector module 250 to either ground out the corresponding antenna element” Par. 0048),
wherein the radiator is a dipole antenna radiator (dipole Par. 0005, 0020).
Regarding Claim 2, Hayes et al. teaches wherein the reflectors are symmetrically and equidistantly arranged around the periphery of the radiator with the radiator as a center (Fig. 3).
Regarding Claim 3, Hayes et al. teaches wherein the antenna structure comprises a total of four reflectors and the four reflectors are respectively arranged at positions of 0 degree, 90 degrees, 180 degrees and 270 degrees relative to the radiator (Fig. 3).
Regarding Claim 4, Hayes et al. teaches wherein the length of the radiator ranges from 0.45λ to 0.55λ (½ of the wavelength for dipole Par. 0020), the length of the one or more reflectors ranges from 0.5λ to 0.62λ (implied that length of reflectors would correspond to ½ of the wavelength of the dipole element as in Par. 0020 and would likewise have a similar length).
Regarding Claim 6, Hayes et al. teaches further comprising one or more wave directors (D1, D2, D8 Fig. 3 Par. 0045), wherein the one or more wave directors are arranged and suspended above the radiator (D1, D2 & D8 are suspended above the radiator 310 as seen in Fig. 3).
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.
Claim 5 is rejected under 35 U.S.C. 103 as being unpatentable over Hayes et al. US Patent Application Publication 2022/0029291.
Regarding Claim 5, Hayes et al. teaches wherein the length of the radiator is 0.5λ (½ of the wavelength for dipole Par. 0020).
Hayes et al. is silent on the length of the one or more reflectors is 0.56λ.
However, Hayes et al. teaches extending and shortening the length of the reflectors (Par. 0007, 0008, 0047-0049), and “the driven element 310 may have a length selected to be about a quarter wavelength for the frequency of operation of the radio circuitry” Par. 0042; and “other dimensions are possible for other frequencies of operation” Par. 0051.
In this particular case, selecting the length of antenna elements such as the length of the one or more reflectors to be 0.56λ is common and well known in the antenna art as evident by Hayes et al. based on the frequency band of operation.
Accordingly, it would have been obvious to a person having ordinary skill in the art before the effective filing date to select the length of the one or more reflectors to be 0.56λ based on the teachings of Hayes et al. as a result effect based on the required frequency band of operation.
Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over Hayes et al. US Patent Application Publication 2022/0029291 and Nakajima et al. WO Patent Application Publication WO2021149143 A1 (see attached machine translation for cited references).
Regarding Claim 8, Hayes et al. teaches the antenna structure according to claim 1 as shown in the rejection above.
Hayes et al. is silent on wherein the angle is a 45-degree angle.
However, Nakajima et al. teaches an angle between the reflectors and the base to be within a range of 0 to 90 degrees (Par. 0005-0007).
In this particular case, adjusting the angle between the reflectors and the ground plane to be within a range of 0 to 90 degrees such as 45 degrees is common and well known in the antenna art as evident by Nakajima et al. to reduce variation in the radiation direction of radio waves (Par. 0005-0007).
Accordingly, it would have been obvious to a person having ordinary skill in the art before the effective filing date to adjust the angle of Hayes et al. to be a 45-degree angle based on the teachings of Nakajima et al. as a result effect in order to improve performance by reducing variation in the radiation direction of radio waves.
Claims 9-14 are rejected under 35 U.S.C. 103 as being unpatentable over Hayes et al. US Patent Application Publication 2022/0029291 and Liu et al. US Patent Application Publication 2016/0302081.
