Patentability shall not be negated by the manner in which the invention was made. Claim(s) 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Haziza et al.

Response to Arguments “Applicant respectfully traverses the rejections of independent claims 1, 8, and 9. In the rejection of claim 1, the Examiner cites the combination of Haziza and Ting as allegedly teaching the features of claim 1. However, Haziza, at para. [0037], merely describes "[a] top dielectric spacer 305 is generally in the form of a dielectric plate or a dielectric sheet, ... ,thereby causing the desired phase shift in the RF signal." Furthermore, Ting, at p4, lines 40 – 9 and p5, merely describes "a frequency tunable antenna, ... ,so as to better control the alignment of the liquid crystals." Haziza and Ting do not disclose a configuration according to an embodiment of claim 1 in which a liquid crystal, a microstrip line, a dielectric, and a patch antenna element are arranged, and the patch antenna element receives a signal from the microstrip line through electromagnetic bonding, and matches the input impedance by changing the permittivity of the liquid crystal." Thus, Haziza and Ting, alone and in combination, do not disclose "a microstrip line on which a signal is transmitted, provided on liquid crystal and extending in a first direction; a dielectric provided on the microstrip line; a patch antenna element provided on the dielectric, that obtains the signal from the microstrip line through electromagnetic bonding and transmits the signal; and at least one memory storing instructions, and at least one processor configured to execute the instructions to; change permittivity of the liquid crystal based on a voltage applied to the liquid crystal to match an input impedance of the patch antenna at a predetermined frequency." “ Applicant's arguments in regards to claim 1 filed on July 1st 2025 have been fully considered but they are not persuasive. Examiner respectfully disagrees that Haziza and Ting fail to disclose "a microstrip line on which a signal is transmitted, provided on liquid crystal and extending in a first direction; a dielectric provided on the microstrip line; a patch antenna element provided on the dielectric, that obtains the signal from the microstrip line through electromagnetic bonding and transmits the signal; and at least one memory storing instructions, and at least one processor configured to execute the instructions to; change permittivity of the liquid crystal based on a voltage applied to the liquid crystal to match an input impedance of the patch antenna at a predetermined frequency." Paragraph 37-42 of Haziza discloses a delay line 325 serving as a microstrip line that generates a desired delay to cause a desired phase shift in the RF signal wherein the delay in the delay line is controlled by the VDC plate (Liquid crystal layer) whose permittivity can be changed based on a voltage applied to the plate. Haziza further discloses a patch antenna, a dielectric, a memory storing instructions, a processor, and a patch antenna obtains the signal from the microstrip line through electromagnetic bonding and transmits the signal. Paragraphs 14-16 of Ting disclose a liquid crystal layer having a voltage applied to it that changes a permittivity of the layer and thus induces a variable capacitance that helps match the input impedance of a patch antenna at a predetermined frequency of operation. Therefore, by giving claim 1 the broadest reasonable interpretation (BRI) we see that Haziza and Ting do disclose the limitations as recited in claim 1. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US 20150380789 A1 (JAKOBY; Rolf et al.) relates to a configuration of a device that includes a patch antenna with a variable liquid crystal layer and positive and negative electrodes to alter the permittivity. US 20220013902 A1 (Bueno-Baques; Dario et al.) relates to a configuration of an antenna device with a variable liquid layer and a program to control its permittivity as well as help with impedance matching of the antenna structures.
