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 .
Applicant’s response (amendments and arguments) filed with the RCE is acknowledged.
Claims 14, 17, 21-23, 29-33 are pending and examined on the merits. The obviousness rejection is maintained, pending further amendment/arguments and/or evidence tied to the objections below. The previous response has overcome the previous written description and indefiniteness rejection.
The examiner invites applicant to schedule an interview to advance prosecution on the merits.
THREE (3) PREVIOUS INFORMATION DISCLOSURE STATEMENTS –
Previously Noted, Retained
The examiner makes note of the following therefrom:
Applicant cites U.S. Patent No. 9937242 (Primary Examiner Bradley) directed to product SEQ ID NOS: 33, 37, and 66 and methods of use bearing specific functionality commensurate in scope with the test data therein. The examiner is open to similar amendments herein that align equivalently with that of ‘242 relevant to the test data herein.
Applicant also submits with the IDS’s, three (3) International Authority Office Actions over the Same/Similar Scope & Dispositions therein:
Japanese-Equivalent 35 USC 112(a) Lack of Enablment Rejection;
Chinese: Equivalent 35 USC 103 Obviousness Rejection (Lack of Inventive Step over a combination of 2 NPL References:
Heng Li et al., Enhanced regeneration and functional recovery after spinal root avulsion by manipulation of proteoglycan receptor PTPo. Scientific Reports, Vol. 5, 14923, 2015-10-14.
in view of
Mahsa Motavaf et al., Attempts to Overcome Remy Clination Failure: Toward Opening New Therapeutic Averues for Multiple Sclerosis, Cellular and Molecular Neurobiology Vol. 37, 1335-1348, 2017-02-21.
Korean-Equivalent 35 USC 112(a) Enablement Rejection and Equivalent 35 USC 103 Obviousness Rejection (Lack of Inventive Step, also over Lang (U.S. Patent Publication No. 20150366949)) as applied herein below.
Information Disclosure Statement Related Material to Examination, Missing
Until Provided, Examination on the Merits Cannot Be Fully Executed
The Information Disclosure Statement filed 9/24/24 cited the related foreign counterpart application in Korea, which was further probed and found to have issued peptide SEQ ID NO: 58 only, which is still claimed here. However, no further Information Disclosure Documents as to why have been found filed. As such is material to examination and not been provided in translated form (like that of the Korean document provided in the 9/24/24 IDS), examination on the merits cannot go forward without submission of such and any other foreign disposition relevant to the subject matter scope here.
Claim Objections – New, Clarifying Amendments Required
The claims are objected to because of the following informalities:
1. The claims are objected to pending further amendment and/or arguments, as dependent claims directed to peptide SEQ ID NOS: 34-60 are no longer found to bear antecedent basis back to the peptide SEQ ID NOS: 32 or 33 of the base claims, upon deletion of the percent identities thereto, absent evidence to the contrary, and are required to be cancelled without prejudice – unless a different subject matter scope was intended in the base claims.
2. The phrase “myelin related disease or disorder” is requested to be amended to demyelating disease or disorder or the like in order to positively recite what type of myelin ‘related’ disease or disorder the peptides are intended to target, even if such may be gathered from the specification as filed.
Appropriate correction is required
Claim Rejections - 35 USC § 103 – Maintained Over All Claims;
Disposition Held in Abeyance Until the Intended Claim Scope is Clarified
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 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 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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
With regard to the obviousness rejections below, the examiner is also in agreement with the U.S. International Authorities disposition in the related PCT written opinion over these same claims filed (without any further amendments) here in the U.S. at the National Stage and applies the same prior art and reasoning here:
Claim(s) 14, 16-17 (SEQ ID NOS: 1-25, 32, 33), 18-22, and new claims 32-33 (SEQ ID NOS: 34-60) remain/are rejected under 35 U.S.C. 102(a)(1) as obvious over Case Western Reserve University (U.S. Patent Publication No. 20150366949 to Lang et al., hereafter “CWRU).
The examiner has now modified the U.S. International Authorities disposition in the related PCT written opinion based on amendments here in the U.S. at the National Stage:

Further, even if the peptides above of CWRU do not in fact exert direct mylenation/remylenation effect, CWRU equally teaches the addition of other agents that do so and based on the open “comprising” transition phrase, the “therapeutic agent” that exerts such effect could equally be one of these:
[0202] The methods described herein can further include administration or contacting a cell (e.g., a neuron) with an agent that blocks regeneration inhibitors, e.g., a compound that inhibit myelin derived blockage of neural generation. Known inhibitors of neuronal outgrowth (e.g., of regeneration at a CNS injury site) are myelin-derived inhibitors (e.g., Nogo-A, MAG, OMgp, Ehprin B3, Sema 4D and Sema 5A), astrocyte derived inhibitors (e.g., CSPG, KSPG, Ephrin B2 and Slit), fibroblast derived inhibitors (e.g., Sema 3A). The second agent may be an antagonist to any of these inhibitors. In one embodiment, the cell is further contacted with one or more such agents. In one embodiment, the agent inhibits a myelin inhibitor of neural regeneration (e.g., myelin-associated glycoprotein (MAG), Nogo, oligodendrocyte myelin glycoprotein (OMgp)). Inhibitors of MAG are disclosed in U.S. Pat. No. 5,932,542. Inhibitors of Nogo are disclosed in U.S. Patent Application Pub No. 2009/0215691. Inhibitors of OMgp are disclosed in U.S. Patent Application Pub. No. 2008/0188411. The cell can be contacted with this agent before, after, and/or concurrently with the agent that inhibits the interaction of CSPG with PTPcs.
Claim 23 remains rejected under 35 U.S.C. 103 as being unpatentable as obvious over Case Western Reserve University (U.S. Patent Publication No. 20150366949 to Lang et al., hereafter “CWRU”), based on the above, further in view of Bernardelli et al. (U.S. Patent Publication No. 20090281084).

Claims 20, 21, and 25-31 is/are rejected under 35 U.S.C. 103 as being unpatentable over Case Western Reserve University (U.S. Patent Publication No. 20150366949 to Lang et al., hereafter “CWRU”) in view of Kirkham et al. (“Neural stem cells from protein tyrosine phosphatase sigma knockout mice generate an altered neuronal phenotype in culture”. BMC Neuroscience 2006, Vol 7, page 50 (pp 1-9)).

As for new claims 26-30, claims 26-27 fall within the scope of that taught by the prior art based on the 70% sequence identity added limitations (claims 26-27). Claims 25 is drawn to a natural pathophysiology of the administered product; claims 27-33 are drawn to one or more subject matter classes already taught/suggested by the prior art based on the scope claimed.
Thus, the claims are deemed prima facie obvious over the references of record.
Response to Amendments/Arguments
Applicant’s arguments have been fully considered but not yet found persuasive for the reasons of record. The rejection is maintained for the reasons above, as modified based on amendments, as to any peptide at least 70% identity to peptide SEQ ID NOS: 32-33, which the prior art of record is still deemed to read on and prima facie obvious to employ for such (and the dependent claims that depend thereto).
Prior Art Made of Record But Not Previously Relied On - Previously Noted
