Office Action

§112
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 . Claims 1-9 are pending in this application. 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 1-9 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. a. Claim 1 and claims dependent thereof are rejected because the term “derivatives” is indefinite. What is covered and what is not? Note that a derivative is a compound that is derived from a similar compound by a chemical reaction or a compound that is imagined to arise from another compound. The examiner recommends that applicants recite the derivatives or delete said term. b. Claim 1 is rejected because the definition of variable R1 in chemical Formula 1 and chemical Formula 2 is not clear. The bond that connects the ring N to the variable R1 in Formula 1 is overlapped with the number 1. PNG media_image1.png 218 306 media_image1.png Greyscale The definition of R1 that includes variables R2 and R3 is also faded. The variable R2 and R3 are fuzzy and appears as Rz or R8. PNG media_image2.png 144 714 media_image2.png Greyscale In Formula 2 as shown below, the variable R1 is not legible. PNG media_image3.png 189 337 media_image3.png Greyscale It is recommended that applicants fix the chemical structures in the claim 1. It is recommended that applicants redraw the chemical structures so that Formula I and Formula II with the variables R1-R3 are legible and not fuzzy. c. Claim 6 is rejected because the phrase “selected from the following group” is not clear. What do applicants mean by “group”? Is the first compound recited part of the group or is it a group by itself? Do applicants mean “selected from the following compounds”, “selected from the following species” or selected from the following”? It is recommended that applicants delete “group” and replace it with “compounds” and also insert “and” before the last compound e.g. “selected from A, B, C and D”. d. In claims 7-9, the phrase “A pharmaceutical composition for the inhibition….” or “A pharmaceutical composition for the preventing or treating diseases….” is indefinite. Literally, it simply states an intention, which is a mental state, not a patentable limitation. Hence the claim is improperly dependent, as it does not further limit the claim on which it depends. That is how the claim has been examined. Alternatively, this may be intended as a method of use claim, in which case, the claim would be garbled, as it begins as a pharmaceutical composition claim, and ends as a method claim. Moreover, as it does not contain any actual step, it would not be a proper process claim. The intended scope of the claim is thus unclear. Specification The disclosure is objected to because of the following informalities: The specification in general is faded and not consistent. For example, at page 8 of the specification shown below, some of the texts are bold and some are faded. PNG media_image4.png 457 677 media_image4.png Greyscale In the specification (pages 1 and 4), the definition of variable R1 in chemical Formula 1 and chemical Formula 2 is not clear. The bond that connects the ring N to the variable R1 in Formula 1 is overlapped with the number 1. The definition of R1 that includes variables R2 and R3 is also faded. The variable R2 and R3 are fuzzy and appears as Rz or R8. It is recommended that applicants replace the specification and also fix the chemical structures in the claims. Appropriate correction is required. Information Disclosure Statement 5. Applicant’s Information Disclosure Statement, filed on 06/07/2024 has been acknowledged. Please refer to Applicant’s copies of the 1449 submitted herewith. Conclusion 6.
