A US appeals court has restored a verdict that found computer software giant Microsoft had infringed on a patent for an anti-piracy technology owned by a competitor, Uniloc USA.

The court said a new trial would be required to establish damages and interest due Uniloc.

Uniloc, which makes , called the ruling a "significant victory" in its eight-year-old suit against Microsoft over an anti-piracy system used in its Windows XP and Office XP products.
