By 1999, Varian Associates had branched into semiconductor, vacuum tube, and medical device fields. On April 2, 1999 these divisions split to become Varian Semiconductor, Varian, Inc. and Varian Medical Systems.

Free speech[edit]

In 1999 Varian Medical Systems, Inc. sued a former employee for defamation in Varian v. Delfino. The terminated employee Dr. Michelangelo Delfino posted numerous messages criticizing the company on the Internet. The case finally settled on undisclosed terms. The lawsuit itself was controversial, heavily publicized, and led to a landmark ruling about California's anti-SLAPP statute. Some market-based workers rights activists uphold Delfino as an example because he mortgaged his house to pay his legal bills related to the lawsuit with Varian.[19]

University of Pittsburgh[edit]

On April 25, 2012 a US federal judge in Pittsburgh awarded attorney fees, costs, and doubled damages totaling $73.6 million to the University of Pittsburgh after the university won a suit on medical patent infringement grounds against Varian.[20]
