Claim Objections 07-29-01 AIA Claim 22 is objected to because of the following informalities: Lines 3 and 4 of claim 22 after the word “comprising” it should be a “:” and not a “;” . Appropriate correction is required. Claim Rejections - 35 USC § 103 07-20-aia AIA The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. 07-21-aia AIA Claim (s) 1, 3, 13 and 22-30 are rejected under 35 U.S.C. 103 as being unpatentable over Majumdar et al.

However, Majumdar teaches chalcogenide material. Therefore, It would have been obvious to one having ordinary skill in the art at the time of the invention was made to have any desired chalcogenide material to enable a faster switching speed with reduced programming currents and on a lower energy consumption since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or working range involves only routine skill in the art. See MPEP 2144.05 . Regarding Claim 29.The device of claim 23, Majumdar ([0036], [0065]) discloses wherein the at least one memory cell, the at least one storage cell, or a combination thereof, are configured to switch or snap when a sufficient voltage is applied across the at least one storage cell, or a combination thereof.
