Seagate Secures Complete Defense Verdict in Major Patent Infringement Jury Trial

United States - Pennsylvania

​A Faegre Drinker intellectual property litigation team won a complete defense verdict for Seagate Technology in a major patent infringement jury trial in the Western District of Pennsylvania. ​​Following a two-week trial, the jury returned a verdict in less than one day finding that Seagate had not infringed any of the 10 claims brought by a former professor at Carnegie Mellon University.

In the case Lambeth Magnetic Structures v. Seagate Technology Holdings et al., Lambeth had filed suit against Seagate claiming that several microscopic layers in the write heads of Seagate's hard drives infringed a patent he obtained in 2006. On behalf of Seagate, the Faegre Drinker team argued that the hard drive write heads did not follow the structure of ultra-thin magnetic layers and crystals described in Lambeth's patent. The team also partnered with Faegre Drinker’s Design Lab to create visual advocacy models to teach the jury the underlying complex technology in the patent.
