Former Sony employee 58-year-old Hidehiro Kume invented a small optical pickup that is used to read and write discs in the PlayStation 2 and the original PlayStation. He didn't feel Sony recognized his contributions, so he took it to court.

A lower Japanese court rejected Kume's claim he deserved compensation, but the Japanese high court ruled that Sony must pay Kume ÂĄ5.1 million (roughly US$60,000) as a reward for his invention.

Kume was seeking ÂĄ100 million.

"I thank the court for identifying some of my contributions to the company," Kume said after the ruling. "But the company should have appreciated my contributions when I was an employee."

Sony is currently examining the court's decision to decide how it will proceed.
