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
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 1-3 and 6 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Beghdadi et al (Synthesis and polymerization of C-vinyl- and N-vinyl-1,2,3-triazoles, Polym. Chem., 2012, 3, 1680-1692).
Beghdadi teaches the following radical polymerization reaction scheme (see page 1687):

Thus, all limitations of claims 1-3 and 6 are met.
Claims 1-6 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Haddleton et al (US 20090082224)
Haddleton teaches a process for making a polymer having pendant side groups comprising: (i) polymerizing an olefinically unsaturated monomer functionalized with an azide group (meeting the limitations of claim 5) by living radical polymerization, most preferably RAFT (meeting the limitations of claim 4), transitional metal mediated living radical polymerization (TMM-LRP) and/or atom transfer radical polymerization, to produce a polymer intermediate (see Abstract).
In particular, the reference discloses a synthesis of the following polymer:

Where circle represented a Wang resin and R is (R =Poly(MMA-co-hostasol) (meeting the limitations of claims 2 and 6, see 0203).
Regarding claim 3, Haddleton teaches polymerizable vinyl halides (see 0032).
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 4-5 are rejected under 35 U.S.C. 103 as being unpatentable over Beghdadi as applied to claims above 1-3 and 6, and further in view of Ricardo et al (Synthesis of Functionalized Polytriazoles via One-Pot Sequential Copper-Catalyzed Azide–Alkyne [3+2] Cycloaddition and Atom Transfer Radical Addition (ATRA), Isr. J. Chem. 2012, 52, 320 – 327).
Beghdadi fails to teach atomic transfer radical polymerization.
Ricardo teaches a The formation of functionalized triazoles was achieved utilizing a ligand-free catalytic system for the cycloaddition between tripropargylamine and vinylbenzyl azide and subsequent addition of tris(2-pyridyl)methylamine (TPMA) ligand in the atom transfer radical addition (ATRA) step (see Abstract).
Ricardo discloses that the corresponding products were obtained in modest yields (50–80 %). The presented methodology enables efficient synthesis of functionalized polytriazoles, which could have a potential use as chelating agents for a variety of transition metals (see Abstract).
Therefore, it would have been obvious to a person of ordinary skills in the art before the effective filing date of the invention to use ATRA methodology for Beghdadi’s polymer synthesis in order to obtain a polymer with moderately high yield with potential use as chelating agents for a variety of transition metals.
