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 .
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.
Response to Amendment
The amendment filed 04/19/2026 has been entered. Claims 1-40 remain pending in the application. Claims 1-16 remain withdrawn from the consideration. Claim 27 is cancelled.
Response to Arguments
Applicant’s arguments with respect to claim 17 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
Applicant's arguments filed 04/19/2026 have been fully considered but they are not persuasive.
In response to applicant's argument that the references fail to show certain features of the invention, it is noted that the features upon which applicant relies (i.e., protein-based biopolymers and not "synthetic methacrylates", EDC/NHS crosslinking (there is an or clause, which only requires NHS or EDS), and collagen that is not in combination with a synthetic polymer (the wording “comprises” leaves room for other components to be in the material, and only requires collagen to be present in some way) are not recited in the rejected claim. Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993).
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 17-40 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Regarding Claim 17, the limitation “said step of crosslinking said collagen solution” lacks proper antecedent basis, as there is not a “step of crosslinking said collagen solution” introduced in the claim.
Claims 18-40 are rejected as well, as they are dependent on claim 17.

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.
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
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.
Claim 17-18, 23, 29-30, and 34 is rejected under 35 U.S.C. 103 as being unpatentable over US 20060241751 A1 (hereafter –Marmo--), in view of US 20140142200 A1 (hereafter --Duan--).
Regarding Claim 17, Marmo discloses a method for the production of an intrastromal corneal lenticule graft for either or both Keratoconus treatment and vision-correction (see paragraph [0063]), configured to mimic native corneal stroma tissue by means of its optical properties, mechanical properties, permeability and interaction with corneal stromal cells (see paragraph [0088]); wherein said method comprising steps of
a. providing at least one portion of said lenticule graft to comprise or to be coated by at least one collagen solution selected from a group consisting of (see paragraphs [0074] and [0088]); collagen, collagen methacrylate, recombinant mammal collagen, mammal-sourced collagen and any combination thereof (see paragraph [0074]); and,
b. processing the lenticule graft by a method selected from 3D printing, laser ablating, molding, and any combinations thereof (see paragraph [0088]).
Marmo fails to disclose wherein said method additionally comprises a step of lyophilizing said collagen solution prior to said step of crosslinking said collagen solution.
Duan discloses a method for the production of an intrastromal corneal lenticule graft for either or both Keratoconus treatment and vision-correction (see paragraphs [0012] and [0041]), configured to mimic native corneal stroma tissue by means of its optical properties, mechanical properties, permeability and interaction with corneal stromal cells (see paragraphs [0019], [0041], and [0046] denoting the lenticle can replace cornea and be placed as a corneal onlay, inlay, or underlay); wherein said method comprising steps of a. providing at least one portion of said lenticule to comprise or to be coated by at least one collagen solution selected from a group consisting of collagen, collagen methacrylate, recombinant mammal collagen, mammal-sourced collagen and any combination thereof (see paragraph [0019] and [0041]); and, b. processing the lenticule graft by a method selected from 3D printing, laser ablating, molding, and any combinations thereof (see paragraphs [0012], [0013], [0016], [0019], [0041]). Duan teaches wherein said method additionally comprises a step of lyophilizing said collagen solution prior to said step of crosslinking said collagen solution (see paragraphs [0016], [0019], and [0042]).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention for the method to further comprise a step of lyophilizing said collagen solution prior to said step of crosslinking said collagen solution, as by doing so would produce dry, uniform, collagen powder with greatly reduced small molecule contaminants, as collagen solutions prepared from such collagen powder have very precise, repeatable collagen concentrations and reaction properties that are essential to two-stage (and more generally, multi-stage) crosslinking methods (see paragraph [0015]).
Regarding Claim 18, Marmo as modified discloses the method of claim 17, additionally comprising step of providing at least one portion of said lenticule to comprise or to be coated by at least one selected from a group consisting Keratocytes and/or stem cells and any combination thereof (see paragraphs [0018], [0064] and [0085]).
