Apple Entitled to $400M in Samsung Profits, Indiana University Maurer School of Law Professors Say in Amicus Brief


Bloomington, Indiana – In a highly publicized intellectual property case involving the design features of smartphones and tablets, the Federal Circuit will decide whether to force Samsung to pay Apple nearly $400 million – Samsung’s total profits on products that infringed Apple’s design patents. Though several high-profile academics have lined up in support of Samsung, Apple’s position on the total profits rule should prevail, according to Indiana University Maurer School of Law experts who have filed an amicus curiae brief in the case.

Apple and Samsung have been battling in dozens of complex intellectual property infringement cases in several countries. At trial in one of the U.S. cases, a jury found that several Samsung devices infringed Apple’s design patents, and awarded Apple all of Samsung’s profits on those devices. On appeal, Samsung is arguing that it should only be required to give up the portion of its profits that can be linked directly to the infringing design features of the products, a theory called “apportionment.”

“Congress debated this same question over a century ago and rejected apportionment,” said Mark D. Janis, the Robert A. Lucas Chair of Law and director of the Center for Intellectual Property Research at the IU Maurer School of Law. He explained that in the mid-1880s, the Supreme Court decided two cases involving carpet designs in which the infringers made thousands of dollars in profits, but the design patent holder was awarded only 6 cents because it failed to prove how much of the profit was attributable to the carpets’ appearance.

“It’s quite clear that Congress was outraged by this result, so it enacted a provision authorizing design patent holders to claim the infringer’s total profits on sales of the infringing products,” Janis said. “Congress understood it would be difficult in many cases for design patent holders to show the precise value that consumers placed on the appearance of a given product, as opposed to its technical features. Rather than a rule that would have left design patent holders with nothing in many cases, Congress decided that the infringer ought to give up all the profits from the infringement.”

A group of academics supporting Samsung argues that the world has changed so profoundly that a rule crafted in the 1880s isn’t suitable any longer and must be changed. Janis and his co-author, Jason Du Mont, the Microsoft Intellectual Property Fellow at the IU Maurer School of Law, aren’t so sure.

“First, that would be a question for Congress to take up, not the courts,” Janis said. “But in any event, it’s not clear whether the current law needs to be changed. In fact, design is probably more valuable to modern consumers than it was in the 1880s. And modern high-tech companies invest massively in design; just read Walter Isaacson’s biography of Steve Jobs. A well-calibrated design patent system plays a role in encouraging that investment.”
