In June 2012, the United States District Court for the Northern District of California enjoined Samsung’s Galaxy Nexus smartphone because it likely infringed Apple’s 8,086,604 patent (the “‘604 patent”) and because Apple was likely to suffer irreparable harm in the absence of an injunction. Apple prevailed at the district court level based on claim 6 of the ‘604 patent — which is practiced by Siri, Apple’s popular voice search companion.
Independent claim 6 is directed to an apparatus for “unified search” using heuristic modules to search multiple data storage locations. As explained by the Federal Circuit, “[u]nified search refers to the ability to access information on more than one data storage location through a single interface. For example, a device equipped with unified search allows the user to search the local memory of the device as well as the Internet by entering a single search query.”
