DETAILED ACTION
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 .
Claim Rejections - 35 USC § 103
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.
Claims 1, 3-7, and 9-17 are rejected under 35 U.S.C. 103 as being unpatentable over Wallace (5468313) in view of Griffith (3489623).
Wallace teaches a nitrocellulose explosive mixed with nitromethane and includes a urethane resin such as diisocyanate and sensitizer such as aluminum (col. 1). Wallace teaches the addition of various diols and glycol components see col. 3 and 4.
Griffith teaches a similar explosive including nitromethane and nitrocellulose and indicates that it is known to use nitrogen contents around 12 % for the nitrocellulose (ex. 3).
It would have been obvious to one having ordinary skill in the art at the time the invention was made and/or filed to use the nitrocellulose with nitrogen content of 12 % as taught by Griffith with the similar composition of Wallace since Griffith teaches that it is known to use various percents of nitrogen content in an explosive containing nitrocellulose and nitromethane.
Claims 2, 8, and 18-20 are rejected under 35 U.S.C. 103 as being unpatentable over Wallace in view of Griffith (3489623) as applied above and further in view of Dejeaifve (20180029951).
Regarding claims 2, 8, 18-20, Dejeaifve teaches that it is known to use retinyl palmitate (a synthetic version of retinyl acetate) as a stabilizer with nitrocellulose explosives.
It would have been obvious to one having ordinary skill in the art at the time the invention was made and/or filed to use the stabilizer as taught by Dejeaifve with the explosive taught by Wallace and Griffith since Dejeaifve teaches that it is a known stabilizer for nitrocellulose.
