In 1985, a small California research company called Cetus began to develop methods for quantifying blood-borne levels of human immunodeficiency virus (HIV), the virus that causes AIDS. A Nobel Prize winning technique developed at Cetus known as PCR was an integral part of these efforts.

In 1988, Cetus began to collaborate with scientists at Stanford University’s Department of Infectious Diseases to test the efficacy of new AIDS drugs. Dr. Holodniy joined Stanford as a research fellow in the department around that time. When he did so, he signed an agreement stating that he “agree[d] to assign” to Stanford his “right, title and interest in” inventions resulting from his employment there. Holodniy’s supervisor arranged for him to conduct research at Cetus to learn about PCR. As a condition of gaining access to Cetus, Holodniy was required to sign an agreement stating that he “will assign and do[es] hereby assign” to Cetus his “right, title and interest in… the ideas, inventions, and improvements” made “as a consequence of [his] access” to Cetus. Working with Cetus employees, Holodniy devised a PCR-based procedure for measuring the amount of HIV in a patient’s blood. Upon returning to Stanford, he and other Stanford employees tested the procedure. Stanford secured three patents to the measurement process.
