Excellent column by Gordon Crovitz in the WSJ on patents and the prospects for reform:
Today’s patent mess can be traced to a miscalculation by Jimmy Carter, who thought granting more patents would help overcome economic stagnation. In 1979, his Domestic Policy Review on Industrial Innovation proposed a new Federal Circuit Court of Appeals, which Congress created in 1982. Its first judge explained: “The court was formed for one need, to recover the value of the patent system as an incentive to industry.”
The country got more patents—at what has turned out to be a huge cost. The number of patents has quadrupled, to more than 275,000 a year. But the Federal Circuit approved patents for software, which now account for most of the patents granted in the U.S.—and for most of the litigation. Patent trolls buy up vague software patents and demand legal settlements from technology companies. Instead of encouraging innovation, patent law has become a burden on entrepreneurs, especially startups without teams of patent lawyers.
…A system of property rights is flawed if no one can know what’s protected. That’s what happens when the government grants 20-year patents for vague software ideas in exchange for making the innovation public. In a recent academic paper (pdf), George Mason researchers Eli Dourado and Alex Tabarrok argued that the system of “broad and fuzzy” software patents “reduces the potency of search and defeats one of the key arguments for patents, the dissemination of information about innovation.”
…For now, the best prospect for real reform is in the Supreme Court, which earlier this month agreed to hear CLS Bank v. Alice Corp., a case about whether a bank’s computerized process for settling transactions via an escrow can be patented. A judge on the appeals court noted this idea was “literally ancient,” developed during the Roman Empire, and should not get a patent now just because a computer is involved.
Addendum: Here is my 2 minute video on some of the problems with patents.
