Story: Court rules in Microsoft's favour on patents
Source code not patentable?
A nice can of worms this opens up: "the court attempted to draw a line: it ruled that "software in the abstract" is not patentable when it is simply a set of instructions detached from any medium — an "idea without physical embodiment". But the ruling suggests that copies of code that can be, for example, downloaded from the internet or inserted in a CD-ROM drive and installed on a computer do qualify as patentable".
Sounds like an algorithm expressed in structured english or even in source code is not patentable any longer.
