A federal judge on Thursday allowed an infringement case against Apple Inc. to proceed in Delaware, ruling that the presence of a single Apple Store in the state is enough to establish proper venue.

The ruling from Judge Mark A. Kearney, visiting from the Eastern District of Pennsylvania, came as judges in the U.S. District Court for the District of Delaware and across the country continue to address an important provision of the patent venue statute that went unaddressed in the U.S. Supreme Court’s landmark ruling May 22 in TC Heartland v. Kraft Foods Group Brands.
