The Supreme Court, as expected, dealt the final blow to Pittsburgh inventor Rand Warsaw's dream of patenting a method for hedging energy costs against changes in the weather. In doing so, however, the court didn't upset the foundations of the multibillion-dollar world of "business method patents," which are based less on a particular machine than a process for achieving some practical end.
It was an anticlimactic end to a case whose decision was so long delayed that some speculated the justices were deadlocked over how far to rein in what some see as an out-of-control patent process. Instead, the court rejected a narrow test that would require patents to involve a machine or transformation of matter and merely said patents can't cover an abstract idea.
