In fact, you are better of not to know. Given that GHC (like all non-trivial software) surely infringes on some patents, the damages that a patent holder can sue you for are less if you do not know about the patents you are infringing on. IIRC, a plaintiff can triple the charges if they can reasonably show that you have been aware of the patents that you are infringing on. Nasty business!
