Years ago, and I mean, like a decade at least, we asked our neuro about a patch for sinemet or actually just levodopa. He said he thought they were working on it in Israel but the problem at that time was the test patches kept burning the skin-apparently it's caustic, and they were trying to figure out how to address that. Since it's been at least ten years since then, I would guess that they weren't able to get around that obstacle. My efforts to find out who and where this research might be being done have been frustratingly unsuccessful.

Stinks, because a patch would be so very much better than taking pills or having a hole in your abdomen.
