Office Action

§102
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 . Response to Arguments Applicant’s arguments with respect to claim(s) 1, 3, and 6 have been considered but are moot in view of the new grounds of rejection. Election/Restrictions Newly submitted claim 15 is directed to an invention that is independent or distinct from the invention originally claimed for the following reasons: it is directed towards a non-elected invention of an organic-inorganic complex hydrogel. Since the applicant has received an action on the merits for the originally presented invention, this invention has been constructively elected by original presentation for prosecution on the merits. Accordingly, claim 15 is withdrawn from consideration as being directed to a non-elected invention. See 37 CFR 1.142(b) and MPEP § 821.03. To preserve a right to petition, the reply to this action must distinctly and specifically point out supposed errors in the restriction requirement. Otherwise, the election shall be treated as a final election without traverse. Traversal must be timely. Failure to timely traverse the requirement will result in the loss of right to petition under 37 CFR 1.144. If claims are subsequently added, applicant must indicate which of the subsequently added claims are readable upon the elected invention. Should the applicant traverse on the ground that the inventions are not patentably distinct, applicant should submit evidence or identify such evidence now of record showing the inventions to be obvious variants or clearly admit on the record that this is the case. In either instance, if the examiner finds one of the inventions unpatentable over the prior art, the evidence or admission may be used in a rejection under 35 U.S.C. 103 or pre-AIA 35 U.S.C. 103(a) of the other invention. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 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. Claim(s) 1, 3, and 6 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Schacht (WO 07/74411 A1). Schacht discloses the following regarding claim 1: a composition for preparing an organic-inorganic complex hydrogel comprising a biocompatible polymer having a photocrosslinkable functional group; and an α-tricalcium phosphate (α-TCP) powder, wherein a weight ratio of the biocompatible polymer and the α-TCP powder is 1:7 to 1:12 (pgs. 16, 31-32). Schacht discloses the following regarding claim 3: the composition for preparing an organic-inorganic complex hydrogel according to claim 1, wherein the biocompatible polymer is at least one selected from the group consisting of alginate, hydroxypropylmethylcellulose (HPMC), hydroxyethylcellulose (HEC), methyl cellulose, carboxymethylcellulose (CMC), gelatin, collagen, fibrinogen, chitosan, agar, matrigel, starch, pectin, polyvinyl alcohol, polyurethane, poly(ethylene glycol), poly(propylene glycol), hyaluronan and poly(vinylpyrrolidone) (pgs. 8-9; claim 6). Schacht discloses the following regarding claim 6: the composition for preparing an organic-inorganic complex hydrogel according to claim 1, wherein the composition further includes at least one of a functional member and a cell (pgs. 10-11, 16-18). Conclusion 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.
