    Is the drainage problem with the patio or the area outside of the patio. If it is the ground outside of the patio the best solution is a french drain. This is a trench dug 12" deep and about 12" wide. You get some pretty inexpensive 4" perforated drainage tile from HomeDepot/ Lowes and a silt sock for it. Put down 4" of 3/4" gravel in the trench, then the pipe, then 2 more inches of gravel then 2-3" of soil and reseed. Will dry the are up in no time. The end of the run needs to go to a drain box of some sort. The easiest optio is to dig a 3' x3' x3' hole and fill with mostly gravel, then the 3" of soil. This system will allow the water to have a place to sit until it can be absorbed in the subsoil.

    We had an awesome paver patio build but had some run off issues. the solution is less than desirable as a box was place at the end of the patio with 12" of concrete surrounding it. Is this really the only option? It looks awful.
