Office Action

§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 . 1. Formal Matters Claims 12-20 are pending and are the subject of this Office Action. 2. Specification A. According to 37 CFR 1.821(d) (MPEP § 2422), where the description or claims of a patent application discuss a sequence listing that is set forth in the "Sequence Listing" in accordance with paragraph (c) of this section, reference must be made to the sequence by use of the assigned identifier, in the text of the description or claims, even if the sequence is also embedded in the text of the description or claims of the patent application. Sequences appear on page 12, line 15, of the specification, but are not identified by SEQ ID NO as required. B. The specification has not been checked to the extent necessary to determine the presence of all possible minor errors, embedded hyperlinks, or improperly referenced trademarks. Applicants’ cooperation is requested in correcting any errors of which Applicants may become aware. 3. Claim Objections A. Though not incorrect, it is noted that claim 15 does not need to recite that the amino acid sequence is set forth in SEQ ID NO:3 since this is recited in claim 12, from which claim 15 depends. B. Though not incorrect, the syntax of claims 15 and 18 can be improved by replacing “the amino acid sequence” with, for example, “and the amino acid sequence” or “wherein the amino acid sequence”. 4. Claim Rejections - 35 USC § 112(a) – scope of enablement The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 12-20 are rejected under 35 U.S.C. 112, first paragraph, because the specification, while being enabling for the treating pancreatic cancer, does not reasonably provide enablement for preventing pancreatic cancer. The specification does not enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make the invention commensurate in scope with these claims. In In re Wands, 8USPQ2d, 1400 (CAFC 1988) page 1404, the factors to be considered in determining whether a disclosure would require undue experimentation include (1) the quantity of experimentation necessary, (2) the amount of direction or guidance presented, (3) the presence or absence of working examples, (4) the nature of the invention, (5) the state of the prior art, (6) the relative skill of those in the art, (7) the predictability or unpredictability of the art, and (8) the breadth of the claims. The breadth of the claims is excessive with regard to claiming preventing pancreatic cancer, as well as for pharmaceutical compositions for its prevention, as this is an intended use. The Examiner has interpreted “preventing” as a condition will not occur in 100% of the subjects administered the intended compound. Applicants provide no guidance or working examples of achieving this, nor is it predictable to one of ordinary skill in the art how to prevent pancreatic cancer from occurring in 100% of the subjects. Applicants may, without adding new matter, consider using a limitation such as “reducing the likelihood”, or a similar phrase. These factors lead the Examiner to hold that undue experimentation is necessary to practice the invention as claimed. 5. Conclusion No claim is allowable.
