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 1-17 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. The term “uneven structure” in claims 1 and 12 is a relative term which renders the claim indefinite. The term “uneven structure” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. It is unclear as to what characteristic is uneven and the limitation is open-ended as to the degree, characteristics, shapes, thickness, materials and any combination thereof that create an uneven structure. Some examples are given in paragraph 36, but are not limited to these elements. Similarly the term “pressure-sensitive” in claims 1 and 12 is indefinite. No degree of sensitivity or types of materials are claimed to define a pressure sensitivity or to what degree. Any known surface would inherently be pressure-sensitive. In one example, a material would be pressure-sensitive when subjected to forces to cause deformation, temperature changes or a combination thereof. Therefore, the Examiner cannot guess as to what type of sensitivity is present, the level of pressure applied or the resulting effect. Remaining claims are rejected on the basis of dependency. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to Eric K Wong whose telephone number is (571)272-2363.
