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 .
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.
Claim(s) 1, 4, 5, is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Razzaq et al., “Oligo(u-pentadecalactone) decorated magnetic nanoparticles,” Journal of Materials Chemistry, vol. 22, pp. 9237-9243 (2012), (hereinafter Razzaq-1).
Regarding Claims 1, 4, 5, Razzaq-1 teaches a core-shell particle with a magnetite core and a shell of oligo(w-pentadecalactone) oligomers with a Mn of 1300 to 3300 g/mol (See abstract and page 9237-9239), which meets the claimed crosslinking agent cited in claims 1, 4, and 5.
Claim(s) 1, 4, 5, is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Razzaq et al., “Multifunctional Hybrid Nanocomposites with Magnetically Controlled Reversible Shape–Memory Effect,” Advanced Materials, vol. 25, pp. 95730-5733 (2013), (hereinafter Razzaq-2).
Regarding Claims 1, 4, 5, Razzaq-2 teaches a core-shell particle with a magnetite core and a shell of oligo(w-pentadecalactone) oligomers in Figure 1

(page 5731), and further teaches a composite obtained by mixing the above ODPL@MNP with a three armed oligo(ω-pentadecalactone) (3AOPDL), and hexamethylene diisocyanate (HDI) and crosslinked (See Figure 1 page 5731 and page 5733), which meets the claimed crosslinking agent cited in claims 1, 4, and 5.
Allowable Subject Matter
Claims 2, 3, and 6, are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter:
The closest prior art is Razzaq-1 and Razzaq-2m as cited above and incorporated herein. Neither Razzaq-1 and Razzaq-2 teaches the core is a silica particle, the claimed size range and/or the claimed molecular weight range.
The next closest prior art is US 2014/0264822 A1 to Horikiri et al. (hereinafter Horikiri). Horikiri teaches a lactone-modified silica filler (para 36), wherein the lactone is a caprolactone (para 40).
Horikiri does not teach wherein the shell is a polymacrolactone.
Claims 7-19 are allowed.
The following is an examiner’s statement of reasons for allowance:
The closest prior art is US 2022/0049041 A1 to Alamri et al. (hereinafter Alamri). Alamri teaches a product of a crosslinking glycidyl methacrylate grafted polyethylene with a polymacrolactone (See abstract).
Alamri does not teach core particle with a shell of a polymacrolactone.
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.”
