Office Action

§112
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 § 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 1-6 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. Claim 1 recites the clause: “a reflection hologram provided such that one principal surface faces the other principal surface of the transparent plate, and configured to reflect, on the one principal surface, the reproduction light transmitted by the transmission hologram and passing through the transparent plate toward the eye of the user”. It is unclear how the reflection hologram can be provided in a way that affects a relationship between the principal surfaces of the transparent plate. Furthermore, there is no antecedent basis for “the other principal surface”, and the phrase “such that one principal surface” appears to refer to the earlier-recited “one principal surface” (from the “an image light…” clause), and thus should have been written “such that the one principal surface”. For examination, this clause will be treated as: “a reflection hologram provided at a side of another principal surface of the transparent plate opposite from the one principal surface of the transparent plate, and configured to reflect, on the another principal surface, the reproduction light transmitted by the transmission hologram and passing through the transparent plate toward the eye of the user”. The subsequent clause will be interpreted as: “an absorption layer provided on the another principal surface side of the reflection hologram, the absorption layer being formed by combining an absorption member configured to absorb a part of the reproduction light not reflected on the another principal surface by the reflection hologram and a transparent member”. Claims 2-6 inherit the deficiencies of Claim 1. Appropriate correction is required. Allowable Subject Matter Claims 1-6, as best understood, would be allowable if rewritten to overcome the rejections based on 35 USC 112(b) explained above. The following is a statement of reasons for the indication of allowable subject matter. With respect to Claim 1, although the prior art discloses various display devices capable of being worn on an eye portion of a user, including: PNG media_image1.png 64 566 media_image1.png Greyscale PNG media_image2.png 306 566 media_image2.png Greyscale The prior art does not appear to disclose or suggest the above combination of features further comprising: PNG media_image3.png 118 568 media_image3.png Greyscale With respect to Claims 2-6, these claims each depend from Claim 1, and are therefore allowable for at least the reasons stated above.
