Now, if that patch is anything like the many, many patches I've done, it is upside down. Whether it will hold or not, only you can guess. Like someone else said, if you can't tug it off, it's stuck! If it can be tugged off at all, re-do it.
Do this test (if you have an unused patch handy): Is the patch perfectly flat on BOTH sides? The patches i'm familiar with are flat on one side and slightly domed on the other. The domed side is (in my experience) the side with the black material. The black portion domes up from the orange portion. It's kind of like two layers, a flat orange portion and the black portion fused to one side.
You would apply the perfectly flat side down so that it fits flat against the surface to be patched.
How does this compare to your patches?
