I find it difficult to imagine mere speech could actually violate someone's patent in light of more recent rulings (more recent than 2011 that is)
The main lynchpin in my thinking is Alice Corp v CLS Bank Intl - that an abstract idea in and of itself is not patentable. I can't imagine a case where mere speech could transcend being an abstract idea ... I suppose there is some slight room on the edges where your source code could be a program that directly interacts with some specific piece of hardware that is covered by a patent ... if that was the case though it seems to me that any program written against a patented processor or architecture would need to be licensed (and maybe that is indeed the case, I'm not a lawyer obviously)
