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 1-18 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 pre-AIA  the applicant regards as the invention.
With regards to Claim 1 and claims depending therefrom, Claim 1 lines 16-19 recite the limitation “each of said refractive structures which contains a prism on the entry surface and a prism on the exit surface of the at least one substrate, wherein the refractive structures cause the light exiting the collimator to pass successively through both prisms of the reflective structures”.  There is insufficient antecedent basis for a refractive structure having a prism on the entry surface and a prism on the exit surface.  Furthermore, it is unclear as to whether each of the refractive structures is required to contain a prism on the entry surface and exit surface of the at least one substrate, or whether only some of the refractive structures are required to contain a prism on the entry surface and exit surface of the at least one substrate.  It is also unclear as to whether only the refractive structures including the prisms cause the light exiting the collimator to pass successively through both prisms of the respective refractive structures, or whether all of the refractive structures include a structure which causes the light exiting the collimator to pass successively through both prisms of the refractive structures having such prisms.  For the purpose of examination, the examiner understands these limitations such that each of the refractive structures contains a prism on the entry surface and a prism on the exit surface of the at least one substrate, such that light exiting the collimator directed toward a refractive structure passes successively through both prisms of such refractive structure.  The applicant is encouraged to clarify in the claim language the required structure of the refractive structures.
With regards to Claim 2, lines 1-2 recite the limitation “the refractive structures cause the collimation of the light exiting the collimator not to be significantly altered”.  It is unclear as to how the refractive structures cause the collimation not to be significantly altered, since refractive structures are understood to cause refraction and it is unclear as to how such refraction causes the collimation not to be significantly altered.  Furthermore, it is unclear as to how altered “significantly altered” is intended to be, and therefore what range of alteration is allowed to be included in the scope of the claim.  For the purpose of examination, the examiner understands this limitation such that the light exiting the collimator enters a prism on the entry surface of a refractive structure as collimated light and exits from a corresponding prism on the exit surface of the refractive structure also collimated.  The applicant is encouraged to clarify in the claim language the structure or feature of the refractive structures allowing the collimation of the light to be not significantly altered, and what is allowed within such degree of un-alteration.
Allowable Subject Matter
Claims 1-18 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
