The only generic Exelon product available is the capsules. These come in four different strengths and are manufactured by Sun Pharmaceutical Industries, Watson Laboratories, and Dr. Reddy's Pharmaceutical Company. It is unclear when a generic version of Exelon patches or solution will become available.

When Will Generic Exelon Patches or Solution Be Available?
The first patent for Exelon patches expired in August 2012. However, generic versions are not yet available. This strongly suggests that other patents or exclusivity rights are still providing significant protection against generic competition. The next patent set to expire will do so in February 2014. This is the earliest predictable date that a generic version of the drug could become available.
However, other circumstances could come up to extend or shorten the exclusivity period. This could include such things as other patents for specific Exelon uses or lawsuits.
It is difficult to predict exactly when generic Exelon solution will become available. Since it is covered by the same patents as Exelon capsules, which are already available in generic form, it appears that there is nothing stopping generic manufacturers from making generic Exelon solution.
