Office Action

§101 §102 §112
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 . Status of the Claims This Office Action is in response to Applicant's Restriction Requirement remarks filed on January 30, 2026. Claim(s) 1-4 are pending. Applicant's election of species of compound 5 with traverse of the restriction requirement in the reply is acknowledged. The traversal is based on the examiners grouping of the compounds. Applicant suggested examining formulae 5 and 42-45. Examiner broadened scope of search to embrace compounds 5 and 42-45. The requirement is deemed proper and is therefore made FINAL. Claim(s) 1-4 are examined herein insofar as they read on the elected invention and species. Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 1-4 are rejected under 35 U.S.C. 101 because the claimed recitation of a use (“an application”), without setting forth any steps involved in the process, results in an improper definition of a process, i.e., results in a claim which is not a proper process claim under 35 U.S.C. 101. See for example Ex parte Dunki, 153 USPQ 678 (Bd.App. 1967) and Clinical Products, Ltd. v. Brenner, 255 F. Supp. 131, 149 USPQ 475 (D.D.C. 1966). Claim Rejections - 35 USC § 112-2 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 1-4 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 1-4 provides for the application of the small-molecules recited in claim 1, but, since the claim does not set forth any steps involved in the method/process, it is unclear what method/process applicant is intending to encompass. A claim is indefinite where it merely recites a use without any active, positive steps delimiting how this use is actually practiced. Claim 1 recites the elected compound as formula 5, however the drawings show the same structure labeled as compound 27. Recited compound 27 in the claims is a totally different compound. The examiner cannot ascertain which part of the disclosure supports the claim. Please check numbering of all compounds. Claim Rejections - 35 USC § 102 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 are rejected under 35 U.S.C. 102 (a)(1) as being anticipated by RN 723737-19-7, RN 723737-17-5, RN 925145-95-5, RN 429620-77-9, and RN 428827-30-9. Examiner notes that the limitation regarding "possessing inhibitory behavior” (claim 2) and the ability to “hinder the capacity of the tumor cell…” (claim 3) are considered properties inherent in the disclosed active agent. "Products of identical chemical composition cannot have mutual exclusive properties." Any properties exhibited by or benefits from are not given any patentable weight over the prior art provided the composition is inherent. A chemical composition and its properties are inseparable. Therefore, if the prior art teaches the identical chemical structure, the disclosed properties are necessarily present. In re Spada, 911 F.2d 705,709, 15 USPQ 1655, 1658 (Fed. Cir. 1990). See MPEP 2112.01. The burden is shifted to the applicant to show that the prior art product does not inherently possess the same properties as the instantly claimed product. The following compounds are known in the art. Compound 5 (RN 723737-19-7): PNG media_image1.png 742 846 media_image1.png Greyscale Compound 42 (RN 723737-17-5): PNG media_image2.png 708 952 media_image2.png Greyscale Compound 43 (RN 925145-95-5): PNG media_image3.png 780 868 media_image3.png Greyscale Compound 44 (RN 429620-77-9): PNG media_image4.png 790 880 media_image4.png Greyscale Compound 45 (RN 428827-30-9): PNG media_image5.png 756 760 media_image5.png Greyscale Conclusion Claims 1-4 are not allowed.
