Apple recently won a preliminary injunction case in Europe banning the sales of Samsung's Galaxy Tab 10.1. Based on a case of infringed intellectual property, Apple was able to convince the court that Samsung's tablet copied the design of the iPad too closely, and Apple requested a block of all sales in the European Union until the case could be further investigated.
It looks like Apple doesn't mind playing a little dirty. A report has surfaced that Apple could have allegedly tampered with and falsified evidence against the Samsung Galaxy Tab, and the ban on the tablet's sales has been lifted in Europe while the court investigates.
