The drawings are not of sufficient quality to permit examination. Accordingly, replacement drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to this Office action. The replacement sheet(s) should be labeled “Replacement Sheet” in the page header (as per 37 CFR 1.84(c) ) so as not to obstruct any portion of the drawing figures. If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. Applicant is given a shortened statutory period of TWO (2) MONTHS to submit new drawings in compliance with 37 CFR 1.81 . Extensions of time may be obtained under the provisions of 37 CFR 1.136(a) but in no case can any extension carry the date for reply to this letter beyond the maximum period of SIX MONTHS set by statute ( 35 U.S.C. 133 ). Failure to timely submit replacement drawing sheets will result in ABANDONMENT of the application.
