MARSHALL, Texas (Legal Newsline) - A Texas-based non-practicing entity this week sued Hewlett-Packard and electronics company LG for infringing its patent through the use of speech recognition software in their products.

Cedatech Holdings LLC, which is based in Plano, Texas, according to court documents, filed its complaints in the U.S. District Court for the Eastern District of Texas Monday.


The federal court has become a popular venue for patent infringement cases because of its set of local rules for such cases and rather fast trial settings.


The entity alleges in the filings that HP and LG have infringed U.S. Patent No. 7,707,591.


The ‘591 patent, entitled “Integration of Audio or Video Program with Application Program,” was originally issued to California-based Talkway Inc. in April 2010.


Cedatech -- for which a website could not be found -- acquired the patent from Talkway, and is the current owner.


The ‘591 patent relates to, among other things, a system running an application program, wherein a separate audio or video program is integrated with the application program.


Cedatech alleges that HP’s 10 tablet and LG’s G Flex smartphone both are using the patented technology, albeit indirectly.


“The G Flex infringes at least one claim of the ‘591 Patent, at least by providing an audio speech recognition program,” the entity wrote in its LG complaint.


Consumers, Cedatech charges, are induced to use the smartphone with speech recognition to provide input into separate application programs.


The entity is seeking damages, pre-judgment and post-judgment interest, costs, attorneys’ fees and a jury trial.


San Francisco-based Tiburon Intellectual Property PLLC and attorney Allen S. Wan in Dallas are representing Cedatech.


Judge Rodney Gilstrap is presiding; however, Magistrate Judge Roy S. Payne is handling all pretrial proceedings in the cases.


Cedatech has filed similar lawsuits against Apple, HTC and Dell.
