Appeal No. 96-3355
Application 08/004,024
DECISION ON APPEAL
This is a decision on the appeal under 35 U.S.C. § 134
from the examiner's rejection of claims 1-4 and 10-18. Claims
6-9 have been cancelled. Claims 5 and 19 have been indicated as
containing allowable subject matter.
The disclosed invention pertains to a method for securing
the outer case of a shaped charge to the loading tube of a
perforating gun. Specifically, the case of the charge and the
loading tube are designed so that the charge can be secured to
the tube by simply inserting the case into a hole of the tube and
twisting the case a predetermined distance.
Representative claim 1 is reproduced as follows:
1. A method of securing a case of a shaped charge to a
loading tube of a perforating gun, comprising:
inserting said case of said shaped charge into a hole
disposed through a wall of said loading tube; and
twisting said case a predetermined distance.
The examiner relies on the following reference:
Regalbuto 4,681,037 July 21, 1987
Claims 1-4 and 10-18 were finally rejected under
35 U.S.C. § 102(b) as anticipated by Regalbuto, or in the
alternative, under 35 U.S.C. § 103 as obvious over Regalbuto.
