First Apple patent challenged at PTAB covers touch-to-zoom tech at center of Samsung war
In late January, however, an inter partes review (IPR) request filed with the Patent Trial and Appeal Board (PTAB) throws the future of one of the Apple patents involved with this case into question. IPR2016-00500, filed by Intellectual Integrity, LLC, of Frisco, TX, challenges multiple claims in Apple’s U.S. Patent No. 7864163, titled Portable Electronic Device, Method, and Graphical User Interface for Displaying Structured Electronic Documents. This is one of only three utility patents owned by Apple brought up in its infringement lawsuits against Samsung. This also marks the first time that an IPR has been requested to review one of Apple’s many patents.
