Antimatter is extremely hard to store, because you must store it in a container that is otherwise evacuated, and you can't let it touch the walls. That means magnetic containment.
However, there are two problems with this. If you store a meaningful number of antiprotons, they will repel each other strongly, and will require absurdly strong magnetic fields (and thus a large amount of energy) to contain them. If you store positrons with the antiprotons, the net charge will be zero, so you won't have to worry about repulsion, but they will form anti-hydrogen atoms, which will be unaffected by the magnetic containment field, touch the walls, and annihilate.
So there's basically no way to store meaningful amounts of antimatter. Additionally, you can't fire it out of a gun, because the instant it contacts regular matter (for example, air halfway down the barrel of the gun), it will annihilate and destroy the gun.

A patent is nearly no indicator of feasibility.
There are patents with claimed functions that are provably categorically impossible.
A patent is a legal monopoly - a cousin of a trademark.
That said, there are several patents with the keyword antimatter.
To find a patent you must go to the uspto website, and search for the keyword.

Here are some patents:
1 7,301,150 Full-Text Method and apparatus for material identification using characteristic radiative emissions

A quick scan yields nothing.. but the thing patented is the claims, not the title. Sometimes the title is purposely ambiguous. Its a patent version of "camping".
