DALLAS, July 9, 2012 /PRNewswire/ -- TransData Inc. today announced that the U.S. Patent and Trademark Office (USPTO) has confirmed the validity of all of the company's United States smart meter patents after concluding a series of ex-parte reexaminations.
TransData's smart meter patents are directed towards wireless "under-glass" communication technology invented by the company for use in digital electric meters. Digital electric meters incorporating this technology are commonly referred to today as "smart meters."

In each case, the request for reexamination came after TransData initiated enforcement actions to protect its intellectual property. The USPTO confirmed the patentability of all pending claims in each of the contested United States patents.
