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 . Priority 2. PNG media_image1.png 222 656 media_image1.png Greyscale Status of Claims 3. Claims 1-25 are pending and under consideration in the instant application. Claim Objections 4. Claims 2-14, 16-20, and 22-24 are objected to for depending on a rejected base claim. Claim Rejections - 35 USC § 112 5. 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. 6. Claim 25 is 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. 7. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 25 recites the broad recitation “carcinomas, melanomas, blastomas, sarcomas, lymphomas and leukemias,” and the claim also recites “including without limitation….” which is the narrower statement of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. 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 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. 8. The following is a quotation of the appropriate paragraphs of pre-AIA 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. 9. Claims 1, 15, and 21 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by CAS Registry Number: RN 1252594-64-1. [Database Registry Chemical Abstracts Service, Columbus, Ohio, Accession No. RN 1252594-64-1. Entered STN: 10 Nov 2010]. PNG media_image2.png 470 560 media_image2.png Greyscale Registry number 1252594-64-1 is available as prior art as of 10 Nov 2010, the date it was indexed into the CAS database. Registry number 1252594-64-1 anticipates compounds of formula I wherein R1, R1 is -C(O)-R9, R9 is piperidine, Ra is NR10R11, R10 and R11 are taken together to form morpholine, Rc is H, R2, R3, R5 are H, M is a bond, R4 is H. Regarding the compositions of claim 21, comprising the anticipatory compounds and an excipient, the Registry entry for Registry no. 1252594-64-1 discloses a mass solubility of 3 g/L, in unbuffered water at pH 9.151. This teaching of water anticipates the claimed composition, wherein the compounds are present with an excipient (i.e., water). See MPEP 2128: ELECTRONIC PUBLICATIONS AS PRIOR ART Status as a "Printed Publication" An electronic publication, including an on-line database or Internet publication, is considered to be a “printed publication” within the meaning of 35 U.S.C. 102(a) and (b) provided the publication was accessible to persons concerned with the art to which the document relates. See In re Wyer, 655 F.2d 221, 227, 210 USPQ 790, 795 (CCPA 1981) Since this date represents the date that each compound entered the CAPlus database on STN, this represents the date that each compound was made accessible to the public. The aforementioned compounds anticipate the instantly claimed compounds: It is further noted that for the purposes of determining if a reference is a “printed publication” for the purposes of 102(b), MPEP 2128 states the following: PNG media_image3.png 99 480 media_image3.png Greyscale where “prior art disclosures…on an on-line database are considered to be publicly available as of the date the item was publicly posted.” Since each of the database entries above lists the date that each compound was entered into the on-line database, the compounds were made publicly available as of that date in each citation, and the claims are anticipated. Conclusion 10. No claims allowed. 11.
