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 . Claims 1-3 are under examination. Response to Applicants Arguments/Amendments Applicants have significantly amended the claims to overcome the 101 rejection; the claims are no longer a product of nature. The examiner has withdrawn the 101 rejection. However, amendments have brought up issues of new matter. The addition of carriers to the pharmaceutical composition was very helpful in overcoming the 101 rejection; however, some of the new amendments do not appear in the original disclosure. Claim Objections Claim I is objected to because of the following informalities: “timp-1” should be –TIMP-1” and “timp-2” should be TIMP-2. Appropriate correction is required. Claim Rejections - 35 USC § 112 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 1-3 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. In regards to claim 1, carriers such as carbomer, hydroxyethyl cellulose, and hydroxypropyl methylcellulose are not mentioned in the specification. The specification does not mention the amount of gelling agent by weight in the claimed composition. In regards to claim 2, the following carrier agents are not mentioned in the specification: cetyl alcohol, stearyl alcohol, glyceryl stearate, or combinations thereof. Glycerin is not mentioned in the specification. In regards to claim 3, the buffering agents such as phosphate buffer and citrate buffer are not disclosed in the specification. Conclusion All claims stand rejected. Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
