During the trial, Marvell argued that it had not used the university’s technology and that those patents were invalid because similar systems had been developed elsewhere before the university filed for its patents. A company spokesman said Marvell would seek lower damages from the judge in post-trial hearings, which are scheduled for May, and might appeal the ruling otherwise.

Patent infringement lawsuits have become a big issue in recent years as the pace of innovation and competition speeds up and technology firms increasingly seek to shield their products behind patents. As the number of technology patents filed in the United States has risen rapidly in the last decade, so have patent-related lawsuits. Recent cases have involved Microsoft, Motorola, Research in Motion, Visto, Google and many others.

In August, Apple won a $1 billion infringement judgment against Samsung over iPhone design patents. Since then, the companies have argued over the size of the verdict and how the jury reached its conclusion. Samsung has argued the figure is excessive, while Apple has sought a court injunction to bar Samsung from selling various products that the jury found infringed on its patents.

Since the jury found the infringement by Marvell had been “willful,” meaning the company knew it was using the patented technology, the judge can award up to three times the verdict amount, according to a statement by K&L Gates, the law firm representing Carnegie Mellon.

The case was tried before Judge Nora Barry Fischer of United States District Court for the Western District of Pennsylvania.
