Nobel laureate Gary Becker and I are on the same page. He says patent terms should be short:
Major reforms to reduce these unproductive opportunities would include lowering typical patent length and the scope of innovations that are eligible for patents. The current patent length of 20 years (longer for drug companies) from the date of filing for a patent can be cut in half without greatly discouraging innovation. One obvious advantage of cutting patent length in half is that the economic cost from the temporary monopoly power given to patent holders would be made much more temporary. In addition, a shorter patent length gives patent holders less of an effective head start in developing follow on patents that can greatly extend the effective length of an original patent.
More importantly, he says we should carve out particularly troublesome areas, like software, from the patent system:
In narrowing the type of innovations that are patentable, one can start by eliminating the patenting of software. Disputes over software patents are among the most common, expensive, and counterproductive. Their exclusion from the patent system would discourage some software innovations, but the saving from litigation costs over disputed patent rights would more than compensate the economy for that cost. Moreover, some software innovations would be encouraged because the inability to patent software will eliminate uncertainty over whether someone else with a similar patent will sue and do battle in the courts.
In addition to eliminating patents on software, no patents should be allowed on DNA, such as identification of genes that appear to cause particular diseases. Instead, they should be treated as other scientific discoveries, and be in the public domain. The Supreme Court recently considered a dispute over whether the genes that cause BRCA1 and BRCA2 deviations and greatly raises the risk of breast cancer is patentable. Their ruling banned patenting of human DNA, and this is an important step in the right direction.
Other categories of innovations should also be excluded from the patent system. Essentially, patents should be considered a last resort, not a first resort, to be used only when market-based methods of encouraging innovations are likely to be insufficient, and when litigation costs will be manageable. With such a “minimalist” patent system, patent intermediaries would have a legitimate and possibly important role to play in helping innovators get and protect their patent rights.
