Cray Wins Summary Judgment Against Raytheon Following Successful Venue Transfer Post-TC Heartland

On April 15, U.S. District Judge William Conley of the Western District of Wisconsin issued an opinion and order in Raytheon Company v. Cray, Inc. granting summary judgment of non-infringement to defendant Cray on two supercomputer patents that had been asserted by Raytheon. The order is the likely conclusion to a case that became an important part of the debate on proper venue in patent cases after the U.S. Supreme Court’s decision in TC Heartland, and aspects of how this case played out after venue was transferred point to the importance of that particular decision on U.S. patent litigation.

Recent court rumblings about a narrow scope of IPR estoppel

An Inter Partes Review (IPR) is an important tool for companies that face frequent patent infringement challenges. An IPR is essentially a mini-litigation focusing solely on patent validity conducted before a panel of administrative patent judges sitting in the Patent Trial and Appeal board (PTAB). Once an IPR is initiated, a decision on validity is issued within one year. The narrow focus, fast timing, and lower cost of an IPR, along with certain legal advantages that make proving invalidity easier in an IPR than in a district court, make it an attractive alternative to district court litigation when good invalidity arguments are available.
