Apple is being sued by Malaysian company StreetSpace over alleged patent infringement covering the technology used in Apple's recently launched iAd mobile advertising platform.

According to website ITProPortal, StreetSpace has based its lawsuit on a US patent titled 'Method and System for Providing Personalized Online Services and Advertisements in Public Spaces', which was awarded to the company in 2005.

StreetSpace's technology delivers targeted ads based on users' location, profile and usage history.

The company has also sued other wireless advertising services providers including Apple owned Quattro Wireless, Google, AdMob, Nokia, Navteq, Millenial Media and Jumptap.
