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 . Drawings New corrected drawings in compliance with 37 CFR 1.121(d) are required in this application because certain of the drawings of record – in particular, Figs. 1-4B – do not have the requisite line quality. Under 37 CFR 1.84(b)(1), black and white photographs (and photocopies thereof) are generally not permitted in patent applications. Applicant is advised to employ the services of a competent patent draftsperson outside the Office, as the U.S. Patent and Trademark Office no longer prepares new drawings. The corrected drawings are required in reply to the Office action to avoid abandonment of the application. The requirement for corrected drawings will not be held in abeyance. 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 18, 20-24, 26-29 and 38 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 use of the term “about” in claims 18, 21, 22-24 and 38 renders the claims indefinite, because the scope of the claimed invention has not been clearly defined. The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph: Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claim 29 is rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Each of the recited limitations has been previously recited in claim 18 (from which claim 29 depends), thus, the claim does not further limit the scope of the invention. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Allowable Subject Matter Claims 18, 20-24, 26-28 and 38 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. Claim 40 is allowed. The following is a statement of reasons for the indication of allowable subject matter: The prior art fails to disclose or suggest a device having each of the recited limitations. While various anatomical training devices are known, including devices comprising synthetic skin tissue with reusable adhesive and formed of various types of materials, the specific configuration of structural elements as recited in claims 18 and 38 as well as the method steps of claim 40 are not disclosed in the prior art, nor is there any motivation or suggestion to modify the teachings of the prior art to create the claimed invention without using impermissible hindsight. As a result, claims 18, 38 and 40, and dependent claims 20-24 and 26-28 contain allowable subject matter. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
