Apple has been taken to court by three inventors, who claim the iPhone's web-browsing interface infringes on a patent the trio holds.
The suit, filed in a Texas court, alleges the technology the device uses to navigate and display websites infringes on a patent the trio obtained last month, which was assigned to registered company EMG Technology.
EMG was founded by one of the three inventors, real estate developer Elliot Gottfurcht.
The patent claims to cover the display of Internet content reformatted from HTML to XML on mobile devices, as well as the technology for manipulating a region of the screen for zooming and scrolling, EMG has announced.
The news of the lawsuit hasn't hurt Apple's share price, which in fact jumped recently due to the announcement that financial services firm JPMorgan Chase has lifted its 2009 and 2010 profit estimates for the company.
JPMorgan analyst Mark Moskowitz has upgraded his projection to $4.86 a share for fiscal 2009 and $5.34 a share in fiscal 2010.
The stock rose 10%, reaching $92.95 at close of trading yesterday, following the announcement.
