I don't know if Panic had any patents regarding this.
The patent system doesn't really benefit the small developer. I was listening to Build & Analyze and Marco Arment was asked if he would patent features of Instapaper and he essentially said that it is more pain than it's worth. They don't have time time and money required to enforce it.
