Office Action

§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 . This is the first action on the merits. Election/Restrictions Applicant's election without traverse of Group (I) in the reply filed on May 8, 2026 is acknowledged. Group (I), drawn to compounds of formula (I), and compositions thereof, embraced by claims 1-32 was elected by Applicant. Applicant has not pointed to any errors in the Examiner’s analysis of the classification of the different inventions. The requirement is still deemed proper and is therefore made FINAL. Applicant elected the following species: PNG media_image1.png 163 368 media_image1.png Greyscale and indicated claims 1-8, 10, 12-15, 18-21 and 23-32 read on said species. The elected species was not found during the search. Therefore, the search was expanded. Claims 1-33 and 36-38 are pending. Claims 1-8, 10, 12-15, 18-21 and 23-32 are under examination. Claims 9, 11, 16, 17, 22, 33 and 36-38 are withdrawn based on the species election and restriction requirement. Information Disclosure Statement The applicant has an obligation to call the most pertinent prior art to the attention of the U.S. Patent and Trademark Office in a proper fashion. Burying one reference in one hundred other IDS references is like citing nothing. PENN YAN BOATS, INC. v. SEA LARK BOATS, INC. 175 USPQ 260 (S.D. Fla. 1972). Golden Valley Microwave Foods, Inc. v. Weaver Popcorn Co. Inc., 24 USPQ2d 1801 (U.S. Dist. N. Dist. IN 1992). Priority Applicant's claim for the benefit of a prior-filed application under 35 U.S.C. 119(e) (PROVISIONAL) or 119(a) (FOREIGN) or under 35 U.S.C. 120 (CONT/CIP), 121(DIV), or 365(c) (WO) is acknowledged. Applicant still has not complied with one or more conditions for receiving the benefit of an earlier filing date under 35 U.S.C. 119(e) as follows: The later-filed application must be an application for a patent application (the parent for an invention which is also disclosed in the prior application or provisional application). The disclosure of the invention in the parent application and in the later-filed application must be sufficient to comply with the requirements of the first paragraph of 35 U.S.C. 112. See Transco Products, Inc. v. Performance Contracting, Inc., 38 F.3d 551, 32 USPQ2d 1077 (Fed. Cir. 1994). The disclosure of the prior-filed applications, Application No. 63583602 and Application No. 63486236, fail to provide adequate support or enablement in the manner provided by the first paragraph of 35 U.S.C. 112 for claims 1-8, 10, 12-15, 18-21 and 23-32 of this application. The present formula (I) is not found in these two documents because the variable Ra is defined broader in the present application. There may be other omissions as well. Thus, the effective filing date of the present claims 1-8, 10, 12-15, 18-21 and 23-32 is the immediate filing date of February 21, 2024. Claim Objections Claim 1 is objected to because of the following informalities: a comma is required between the first two groups in the definition of R1, line 2. Appropriate correction is required. Claim Rejections Claims 1-8, 10, 12-15, 18-21 and 23-32 are rejected as each directed to an improper Markush group. These Markush claims are rejected under the judicially approved ‘‘improper Markush grouping’’ doctrine when the claim contains an improper grouping of alternatively useable species. In re Harnisch, 206 USPQ 300 (CCPA 1980). A Markush claim contains an ‘‘improper Markush grouping’’ if: (1) the species of the Markush group do not share a ‘‘single structural similarity,’’ or (2) the species do not share a common use. The species of the present claims do not share a ‘‘single structural similarity. Therefore, a rejection on the basis that the claims contain an ‘‘improper Markush grouping’’ is appropriate. The rejection of the claims will be maintained on the basis that the claims contain an ‘‘improper Markush grouping’’ until the claims are amended to include only species that share a single structural similarity and a common use, or the applicant presents a sufficient showing that the species in fact share a single structural similarity and a common use. Under principles of compact prosecution, the applicant elected a single disclosed species for search and examination (i.e., an election of species). The prior art search did not find the elected species in the prior art, and the search has been extended to those additional species that fall within the scope of a permissible Markush claim. In other words, the search has been extended to the species that share a single structural similarity and a common use. Proper Markush claims will be examined for patentability over the prior art with respect to the elected species or group of indistinct species, as well as the species that share a single structural similarity and a common use with the elected species or group of indistinct species (i.e., the species that would fall within the scope of a proper Markush claim). Federal Register, Vol. 76, No. 27, 02-09-2011, page 7166. Claims 1-8, 10, 12-15, 18-21 and 23-32, directed to the nonelected species, are withdrawn from further consideration. The prior art search will not be extended unnecessarily to cover all nonelected species. The rejection may be overcome by limiting the claims to the elected Markush group, wherein A= pyridine ring, R2= piperdine or piperazine and R3= pyridine ring. 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 and 31 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 pre-AIA the applicant regards as the invention. Regarding claim 1, the cycloalkyl group in the wherein clause in the definition of R1 lacks antecedent basis. See also the objection above where a comma is required in the definition of R1. Claim 31 is vague because claims may not refer to the specification. Verily, claims that refer to the specification are improper. See Ex parte Fressola, 27 USPQ.2d 1608 (BPAI 1993). Claim 31 improperly refers to Table 1. The above-mentioned rejection under 35 U.S.C. § 112, 2nd will be obviated by the following suggestions: inserting the compounds into the claim. The following is a quotation of the fourth paragraph of 35 U.S.C. 112: Subject to the [fifth paragraph of 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claims 13 and 14 are rejected under 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. In said claims, the phrase, “one or more Ra” is broader than claim 1. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Claim 20 is rejected under 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. In said claim, the subformulas PNG media_image2.png 75 198 media_image2.png Greyscale does not further limit claim 1. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. 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 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. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-8, 10, 12-15, 18-21 and 23-32 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Gao et al. (WO 2024240108, filing date of May 19, 2023, cited on the IDS). The reference teaches the elected species: PNG media_image3.png 304 901 media_image3.png Greyscale , see compound 33 on page 6. The compositions are taught on page 47, claim 7. Thus, said claims are anticipated by Gao et al. Claims 1-3, 7, 8, 12-15, 18-21, 26 and 27 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Aurora Fine Chemicials (Chemical Abstracts (STN), Registry number 1794059-51-0, publication date of July 5, 2015). The reference teaches the elected species: PNG media_image4.png 285 882 media_image4.png Greyscale PNG media_image5.png 207 525 media_image5.png Greyscale . Thus, said claims are anticipated by Aurora Fine Chemicals.
