Regarding Claim 3, on line 2, change “the base of claim 2; and” to --the base.-- Regarding Claim 4, on line 4, change “; and” to --.--. Regarding Claim 5, on line 4, change “; and” to --.--. Regarding Claim 6, on line 4, change “; ” to --.--. Regarding Claim 7, on line 1, change “A banjo mute or damper” to --The banjo mute and damper--. Appropriate correction is required. Claims 4-6 are objected to under 37 CFR 1.75(c) as being in improper form because a multiple dependent claim should refer to other claims in the alternative only. See MPEP § 608.01(n). Accordingly, the claims have not been further treated on the merits. 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 1-7 (claims 2-3 as being dependent claims) 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. Claim 1 recites the limitation "said upper post and platform" in line 7. There is insufficient antecedent basis for this limitation in the claim.

Claim 5 recites “such as leather or foam, or harder damping material such as brass or wood”. The phrase "such as" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Examiner suggest amending the claim as follows: The banjo mute and damper as in claim 4, further comprising a flat platform supported by said hollow post a . Regarding Claim 6, lines 2-4 recite “which may isolate”, “may be notched”, and “may support”. It is unclear what is meant by “may isolate”, “may be notched” and “may support”.

Regarding Claim 7, lines 1-3 recite “wherein said apparatus may be applied for benefit of tonal and volume changes in other stringed musical instruments which many accommodate its design and basic”. It is unclear what is meant by “may be applied for “ and “which may accommodate”. Additionally, line 5 recites “such as the wooden back or brace of a guitar”. The phrase "such as" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d).
