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 1-20 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 "the two voltage-sensing electrodes of each leg of the user" in lines 29-30. There is insufficient antecedent basis for this limitation in the claim. Claim 2 recites the limitation "the at least one accelerometer-gyroscope module" in line 1. There is insufficient antecedent basis for this limitation in the claim. Claim 3 is rejected as being dependent upon a rejected base claim. Claim 4 recites the limitation “a mobile application” in line 4. It is unclear whether this limitation refers to the application recited in line 3 of claim 1, or a different application. It should be noted that claim 5 also recites “the mobile application” in line 1. Claim 5-8 are rejected as being dependent upon a rejected base claim. Claim 9 recites the limitation "the third voltage sensing electrode" in line 2. There is insufficient antecedent basis for this limitation in the claim.

Claims 11-12 are rejected as being dependent upon a rejected base claim. Claim 13 recites the limitation "the one or more target measuring areas" in line 1. There is insufficient antecedent basis for this limitation in the claim. Claims 14-16 are rejected as being dependent upon a rejected base claim. Claim 17 recites the limitation "the electrode configuration" in line 1. There is insufficient antecedent basis for this limitation in the claim. Claim 17 also recites the limitation “a circular current injecting band electrode” in lines 1-2. It is unclear whether this limitation refers to one of the two current-injecting electrodes recited in claim 1, or a different current injecting electrode. Claim 18 recites the limitation "each pair of current-injecting band electrodes" in line 2. There is insufficient antecedent basis for this limitation in the claim. Claim 19 is rejected as being dependent upon a rejected base claim. Claim 20 recites the limitation “impedance monitor having a multiplexed” in line 1. It is unclear whether the “impedance monitor” refers to the “at least one bio-impedance module” recited in claim 1, or a different impedance monitor. It is also unclear whether the limitation “multiplexed” refers to the multiplexor recited in claim 1, or a different element. Claim 20 also recites the limitation "the wearer" in line 2. There is insufficient antecedent basis for this limitation in the claim. Claim 20 also recites the limitation "a sequence" in lines 2-3. It is unclear whether this limitation refers to the “configuration sequence” recited in line 6 of claim 1, or a different sequence.
