IBM claims Amazon is guilty of patent infringement and is taking the e-commerce giant to court.

The company said it hit Amazon with two lawsuits that seek unspecified damages last week, claiming it attempted to clear up the matter for four years before it decided to sue.

IBM alleges that Amazon knowingly exploits its intellectual property by infringing on several patents that cover, among other things: the presentation of applications in an interactive service; the storage of data in an interactive network; the presentation of advertising in an interactive service; and the ordering of items from an electronic catalogue.

Amazon was first noted about the alleged infringement in September 2002 according to IBM, which claims Amazon hasn't wanted to engage in "meaningful discussions". Other companies license the patents in question, according to IBM.

Neither company was immediately responded to requests seeking comment.
