Apple is expected to get a new chance in a US appeals court to go ahead with its claims that Google’s Motorola Mobility infringed its iPhone technology.

Both the firms have accused each other of copying several patents related to their respective mobile phones and filed various lawsuits globally.

In the latest development, Apple and Motorola are asking a US judge to reopen a lawsuit, in which they accused each other of illegally infringing patented technology.

The Wall Street Journal reported that a US appeals court, hearing oral arguments on Wednesday, suggested that an influential Chicago-based federal judge went too far last year in tossing Apple’s lawsuit.

Last year, Apple sued Motorola for infringement of four patents related to the smartphone and set-top TV-box, some of which are used in Motorola’s Droid-branded mobile phones and in its Xoom tablet.

Motorola alleged that Apple’s products including the MobileMe and the App Store violated 18 patents it owns.

In 2011, Motorola won a patent dispute against Apple in Germany after the Manheim court found the iPhone maker guilty of infringement of one of the company’s cellular-communications patents.
