Something has gone very wrong with the United States patent system.

Americans think of the granting of patents as a benevolent process that lets inventors enjoy the fruits of their hard work and innovations. But times have changed. The definition of what is patentable has slowly evolved to include business practices and broad ideas. The fact that the Smucker's company went to court over patents on peanut butter and jelly sandwiches might have provoked chuckles. But it became a symbol of a system gone awry.

Technological advances raise new questions with each passing year. Should genes be patentable? What about life forms? The high-tech and pharmaceutical industries find themselves at odds on reform because patents affect their businesses so differently. The understaffed Patent and Trademark Office needs to draw the line between a real innovation and an obvious concept that should be freely available as a building block for future generations of creative thinkers.

Meanwhile, profiteers, including lawyers and hedge funds, have turned the very purpose of patent rights -- to encourage people to invent and produce -- on its head, using them to tax, blackmail and even shut down productive companies unless they pay high enough ransoms. These so-called patent trolls have emerged as the villains in this intellectual property debate.

The possibility of this sort of abuse is inherent in the concept of patents, which in this country allow no one to produce or sell a patented product for up to 20 years without a license from the patent holder. Our nation's founders considered intellectual property important enough to include in the Constitution, but did not establish the system for the sake of the inventor. It exists for the sake of society, or, as it says in the Constitution, "to promote the progress of science and the useful arts."
