Office Action

§102
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 . Election/Restrictions Applicant's election with traverse of Group I, claims 1-2, in the reply filed on 6/16/26 is acknowledged. The traversal is on the ground that the process of Group II cannot be practiced with another materially different composition than the composition of Group I. This is not found persuasive because the Examiner has sufficiently shown a concurrent examination of the inventions would present a “serious burden”, as set forth in the restriction requirement mailed 5/26/26. Specifically, after the Examiner provides all the inventions, I and II being independent or distinct for the reasons given in restriction requirement mailed 5/26/26, the Examiner has provided reason(s) that there would be a serious search and/or examination burden if restriction were not required because one or more of the following reasons apply: the inventions have acquired a separate status in the art in view of their different classification, the inventions have acquired a separate status in the art due to their recognized divergent subject matter, and the inventions require a different field of search (e.g., searching different classes/subclasses or electronic resources, or employing different search strategies or search queries). The requirement is still deemed proper and is therefore made FINAL. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. Claims 1-2 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Yoshinaga et al (1997). Yoshinaga teaches protection by trehalose of DNA from radiation damage. Yoshinaga, table 1, teaches DNA solutions with trehalose. DNA and trehalose are both charge dissipative components not capable of forming a layer of self limiting thickness when electrosprayed without a component as claimed in claim 1. A combination of DNA and trehalose read on a plurality of chare dissipative components as claimed in claim 1. Regarding claim 2, DNA reads on a nucleic acid as claimed in claim 2. Trehalose reads on a charge-dissipative crystalline material as claimed in claim 2. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US20140274944 teaches sprayable hemostat using soluble oxidized cellulose with miniaturized electrospray system.
