California - Lenovo Inc., Barnes & Noble Inc., Amazon.com Inc. and other makers of tablet products were hit with new infringement allegations on Friday at the hands of Hopewell Culture & Design LLC, which accuses the tablet makers of misappropriating its patented technology for double-clicking an interactive display.
Hopewell filed a battery of new infringement lawsuits in Texas federal court against Lenovo, B&N, Amazon, Coby Electronics Corp., Viewsonic Corp. and Vizio Inc. all asserting violations of its rights in U.S. Patent Number 7,171,625.
The '625 patent, entitled "Double-Clicking a Point-and-Click Interface Apparatus to Enable a New Interaction with Content Represented by an Active Visual Display Element," was issued in January 2007. The claimed invention can be used to enable interaction with any type of content, such as a still image, video, audio, text or a graphical display, and the interactions can include any manner of making use of data representing the content, according to the patent description.
The tablet makers are making and selling infringing mobile devices including B&N's Nook, Amazon's Kindle, Lenovo's ThinkPad andIdea Pad, Coby's Kyros, Viewsonic's ViewBook and Viewpad and Vizio's VTAB1008, according to the complaints.
The accused devices all allegedly infringe the patent by having software allowing a user to double click or double tap a visual element representing interactive content and interact with a second version of the interactive content.
Hopewell is seeking a declaration of infringement, damages and injunctions with respect to all of the alleged infringers.
The '625 patent claims a broad range of double-clicking capabilities and functionality, covering computers, televisions and any other devices that make use of a point-and-click apparatus for user interaction.
"Double-clicking a point-and-click computer user interface apparatus can also be used to effect user input to a computer program," the patent description says. "However, double-clicking has not been used to effect user input to a Web browser that uniquely corresponds to the double-click input."
"Once users have become acclimated to the use of a double-click input to produce or enable functionality in accordance with the invention, the invention can provide an intuitive and easy way to access such functionality," the description says.
