CLAIMS 1-21 ARE PRESENTED FOR EXAMINATION
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 .
Applicant’s amendment, remarks and Information Disclosure Statement filed April 13, 2026 have been received and entered into the application. As reflected by the attached, completed copies of form PTO/SB/08, the cited references have been considered by the Examiner. Also, the application papers have been amended as directed.
In light of Applicant’s remarks and amendments, the previously set forth rejections under 35 USC 103 and the grounds of provisional double patenting have been overcome and are hereby withdrawn.
Claims 1-15 are in condition for allowance.
Claim Rejection - 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 16-21 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.
Each of claims 16-21 recites a physiological result which follows the
administration of minoxidil as per the method of claim 1. However, such a result does not equate
to a further limitation of the patient population, minoxidil dosage form, minoxidil dosage amount or the step of administration as recited in claim 1 and thus the supposed further limited metes and bounds of the subject matter of these claims as compared to claim 1 would be unclear to one of ordinary skill in the art.
For example, with respect to claim 16, the phrase "results in no tachycardia" makes the
claim indefinite because one of ordinary skill in the art could not reasonably determine the metes
and bounds of this limitation. Specifically, it is not clear how this limitation in claim 13 further
limits either the patient population in need of hair loss treatment, the dosage form, the dosage amount or the method step of oral administration, or adds some of functional-descriptive limitation to the claim which is not found in claim 1, the claim from which this claim depends.
The specification uses the term "tachycardia" on nine specific instances (see paragraphs
0031, 0033, 0034, 0151, 0153, 0369, 0372, 0466, and 0472). However, none of the appearances
of the limitation in claim 13 in the specification explains how a treatment method without
tachycardia is achieved.
Paragraphs 0151 and 0152 of the Specification state:
"In some embodiments of the method described herein, administering results in
substantially no cardiac effects. In some embodiments, the cardiac effects are selected from
tachycardia, hypotension, premature ventricular contractions, and other tachyarrhythmias.
In some embodiments of the method described herein, administering results in hair
regrowth with substantially no clinically significant hemodynamic changes in blood pressure. In
some embodiments, administering results in hair regrowth with substantially no cardiac effects.
In some embodiments, the daily dose of minoxidil or a pharmaceutically acceptable salt thereof
results in substantially no cardiac effects or hemodynamic effects as compared to administration
of an immediate-release oral minoxidil or a pharmaceutically".
Paragraph 0466 of the Specification demonstrates a clinical trial using 5 mg that 1 patient
developed tachycardia, which appears contrary to claim 13's intended result of the functional
descriptive claim language.
Taken as a whole, it is still not clear how the disputed limitation of claim 13 further limits
claim 1, and is therefore indefinite.
The same rationale can be applied to the supposed limitations of claims 17-21
resulting in the same conclusion that one of ordinary skill in the art would be unable to
reasonably ascertain the supposed further limiting metes and bounds of the claimed subject
matter.
Accordingly, the claims are deemed properly rejected.
