The International Trade Commission (ITC) has reported that Apple did not infringe upon a Motorola patent involving mobile touchscreen technology.
ITC official's findings come following Motorola's request to review a previous dismissal ruling. The case continues a lengthy patent battle between the two smartphone makers.
Officials found that patent number 6,246,862 was not infringed upon by Apple's mobile products. The patent covers technology which prevents accidental touchscreen input through the use of a close-proximity sensor.
The technology is common among the current crop of today's smartphones. An example of the technology in the real-world includes the ability of a smartphone to disable touch when a user places the phone by their face to talk.
ITC officials ruled that Apple did not infringe upon the patent because it's an obvious technology that could have been made without Apple directly infringing upon the patent. Officials' ruling upholds an Administrative Law Judge's decision from late last year.
The case can still be appealed by Motorola. V3 contacted both Motorola and Apple for comment on the news but neither firm has responded for comment as of this writing.
Motorola's dismissal is part of a larger patent fight between it and Apple. The two firms have been in a consistent legal battle over the last few years. Fighting began to ramp up following Google's purchase of Motorola last year.
Some have questioned whether Google's main motive to purchase Motorola was because of the firm's vast patent portfolio. According to reports, the company paid upwards of $5bn for Motorola's patents alone.
In a Security and Exchange Commission filing from last year Google reported that the patents would help protect its investments from future litigation. Google built the Android mobile OS, the primary competitor to Apple's iOS in the mobile marketplace.
