• The Earth revolves around the Sun.

• The speed of light is a constant.

• Apples fall to earth because of gravity.

• Elevated blood sugar is linked to diabetes.

• Elevated uric acid is linked to gout.

• Elevated homocysteine is linked to heart disease.

• Elevated homocysteine is linked to B-12 deficiency, so doctors should test homocysteine levels to see whether the patient needs vitamins.

ACTUALLY, I can't make that last statement. A corporation has patented that fact, and demands a royalty for its use. Anyone who makes the fact public and encourages doctors to test for the condition and treat it can be sued for royalty fees. Any doctor who reads a patient's test results and even thinks of vitamin deficiency infringes the patent. A federal circuit court held that mere thinking violates the patent.

All this may sound absurd, but it is the heart of a case that will be argued before the Supreme Court on Tuesday. In 1986 researchers filed a patent application for a method of testing the levels of homocysteine, an amino acid, in the blood. They went one step further and asked for a patent on the basic biological relationship between homocysteine and vitamin deficiency. A patent was granted that covered both the test and the scientific fact. Eventually, a company called Metabolite took over the license for the patent.

Although Metabolite does not have a monopoly on test methods — other companies make homocysteine tests, too — they assert licensing rights on the correlation of elevated homocysteine with vitamin deficiency. A company called LabCorp used a different test but published an article mentioning the patented fact. Metabolite sued on a number of grounds, and has won in court so far.

But what the Supreme Court will focus on is the nature of the claimed correlation. On the one hand, courts have repeatedly held that basic bodily processes and "products of nature" are not patentable. That's why no one owns gravity, or the speed of light. But at the same time, courts have granted so-called correlation patents for many years. Powerful forces are arrayed on both sides of the issue.

In addition, there is the rather bizarre question of whether simply thinking about a patented fact infringes the patent.
