Shipment delays aside, Asus now has another problem involving its Tegra 3-powered Eee Pad Transformer Prime tablet, a trademark lawsuit. Last week US-based toy maker Hasbro has filed a complaint with the Los Angeles federal court through which it accuses Asus of violating its uber-popular 'Transformers' trademark.

Hasbro is obviously annoyed with the name of Asus' tablet which combines two important brands - Transformers and Optimus Prime. To 'make things right', Hasbro is asking for monetary damages and a temporary injunction that would prevent the sale of the Transformer Prime in the US.

Asus didn't respond to the lawsuit but it's probably taking action to ensure nothing disrupts Transformer Prime sales.
