The law suit against software patents grinds along. Well, it has nothing to do with software except in an inverted manner.
Engineering News-Record's Melissa Traynor and Tom Sawyer report that a case involving business patents will be heard in December by the US Supreme Court. The US Patent Office rejected Bernard Bilski’s patent for a risk hedging method.
The US Court of Appeals last October said that business-method patent applications must be tied to machines, or else transform one article into another. The former test required that patents produce "useful, concrete and tangible results."
Traynor and Sawyer do a good job interviewing those for and against changes to what can be patented. A worthwhile read.
Killing software patents in the CAD industry would spur innovation, since competitors currently are wary of implementing features patented by others.
