Isamu Kaneko, a former tutor at the University of Tokyo, was arrested in 2004 after being accused of helping users distribute copyrighted material on the Internet.

Kaneko is the creator of the anonymous P2P software, Winny, and prosecutors tried to hold him responsible for the infringements of others who used it, saying that he was aware that his program would be put to illicit uses.

In 2006, the Kyoto District Court found Kaneko guilty, and handed out a fine equivalent to around $17,000.

Earlier this month, however, the Osaka High Court acquitted the 39 year old, overturning the earlier verdict.

“Today’s ruling helps not only myself but also other computer engineers in pursuing the development of computer technology,” said Kaneko.

But the celebrations were to be short-lived.

Dissatisfied with the decision, prosecutors have announced that they have appealed to the Supreme Court .

“It’s regrettable,” said Kaneko, commenting on the news, “but I will secure a not guilty verdict again at the top court.”
