Office Action

§112
Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. DETAILED ACTION Priority and Status of Claims 1. This application is a CON of 16284035 02/25/2019 PAT 11660286, which is CON of 14349010 04/01/2014 ABN, which is a 371 of PCT/US2012/058964 10/05/2012, which claims benefit of the provisional application 61544375 with a filing date 10/07/2011. 2. Claims 1-2, 5, 10, 13-15, 19, 21, 23, 25-26, 29-31, 35, 38, 41, 46 and 84 are pending in the application. Claim Rejections - 35 USC § 112 3. 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 1-2, 5, 10, 13-15, 19, 21, 23, 25-26, 29-31, 35, 38, 41, 46 and 84 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112, first paragraph (pre-AIA ), because the specification does not reasonably provide enablement of the instant “modulator of hemoglobin” without limitation (i.e., no named compound or formula). 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. ln In re Wands, 8 USPQ2d 1400 (1988), factors to be considered in determining whether a disclosure meets the enablement requirement of 35 U.S.C. 112, first paragraph, have been described. They are: 1. the nature of the invention, 2. the state of the prior art, 3. the predictability or Iack thereof in the art, 4. the amount of direction or guidance present, 5. the presence or absence of working examples, 6. the breadth of the claims, 7. the quantity of experimentation needed, and 8. the level of the skill in the art. In the instant case: The nature of the invention The nature of the invention is a method of use using “modulator of hemoglobin” without limitation (i.e., no named compound or formula), see claims 1 and 25. The state of the prior art and the predictability or Iack thereof in the art The state of the prior art is Oronsky et al. US 11,660,286, it discloses a compound of formula (I) as a modulator of hemoglobin, see column 3. The amount of direction or guidance present and the presence or absence of working examples The only direction or guidance present in the instant specification is the description of a number of “modulator of hemoglobin” of formula (I) or (II) on page 8 of the specification. There is no data present in the instant specification for the “modulator of hemoglobin” without limitation (i.e., no named compound or formula). The breadth of the claims The instant breadth of the rejected claims is broader than the disclosure, specifically, the instant “modulator of hemoglobin” is without limitation (i.e., no named compound or formula). The quantity or experimentation needed and the Ievel of skill in the art While the level of the skill in the chemical arts is high, it would require undue experimentation of one of ordinary skill in the art to resolve any “modulator of hemoglobin” without limitation. There is no guidance or working examples present for constitutional any “modulator of hemoglobin” without limitation for the instant invention. Incorporation of the limitation of “modulator of hemoglobin” (i.e., formula (I) and (II) of claim 14) supported by specification into claims 1 and 25 respectively would overcome this rejection.
