Office Action

§112
DETAILED ACTION Summary This is the initial Office Action based on the Semi-Automatic Portable Solar Controller filed December 7, 2023. A telephonic call was made and an email was sent to Applicant on December 5, 2025 but did not result in a return call or email. Applicant is encouraged to contact the examiner, Dustin Dam, at (571) 270-5120. Claims 1-6 are currently pending. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-6 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claims 1-6 are rejected as failing to define the invention in the manner required by 35 U.S.C. 112(b) or pre-AIA 35 U.S.C. 112, second paragraph. The claim(s) are narrative in form and replete with indefinite language. The structure which goes to make up the device must be clearly and positively specified. The structure must be organized and correlated in such a manner as to present a complete operative device. The claim(s) must be in one sentence form only. Claims 1-6 are not in the form of one sentence. For example, claim 1 begins with “A semi-automatic portable solar controller comprising:…” and claim 1 also recites in the middle of the claim, “An adjustable mechanism”, “The stabilizing mechanism”, “Multiple U-shaped blocks”, and multiple other capitalized terms rendering the claim not in the form of one sentence. Similarly, claims 2-5 also contain multiple capitalized terms in the middle of the claim rendering the claim not in the form of one sentence. Claim 1 recites the limitation "the other end of the support rod" on line 3. There is insufficient antecedent basis for this limitation in the claim. As there is no previously recited “other end of the support rod”, it is unclear as to what "the other end of the support rod" recited on line 3 of claim 1 is referring to. Dependent claims are rejected for dependency. Amending “the other end of the support rod” to “another end of the support rod” would overcome the rejections. Claim 1 recites, “each adjustable mechanism” on line 6. However, claim 1 previously recites, “An adjustable mechanism” on line 5. It is unclear how many adjustable mechanisms are required in the claim. Dependent claims are rejected for dependency. Claim 1 recites the limitation "The stabilizing mechanism" on line 7. There is insufficient antecedent basis for this limitation in the claim. As there is no previously recited “stabilizing mechanism”, it is unclear as to what "The stabilizing mechanism " recited on line 7 of claim 1 is referring to. Dependent claims are rejected for dependency. Amending “The stabilizing mechanism” to “a stabilizing mechanism” would overcome the rejections. Claim 1 recites the limitation "the inner walls of the two triangular blocks" on line 7-8. There is insufficient antecedent basis for this limitation in the claim.
