Software Patents Compared to Hard Patents

Arie writes "The Slate discusses the obvious differences between patenting an algorithm and a drug. The article introduces the Fence test, which basically says that if you can physically protect your property, you have a case patenting it. In addition, it claims that the burden on a programmer identifying whether he is infringing on a patent or not involves excessive research burden, essentially to the inherent lack of physical boundaries. Obviously the article starts off with mentioning the patent dispute between RIM and NTL."
