Taiyo Yuden Files Patent Infringement Suite
Taiyo Yuden, a well known CD and DVD manufacturer for quality regular and printable media, and the most widely used media for CD and DVD Duplicators, filed suit against two other manufacturers for patent infringement. Taiyo Yuden filed the suit in the United States against Prodisc and Ritek.

Taiyo Yuden filed the suit at a California district court against Prodisc Technology on Oct. 30 and the second suite filed in California against Ritek on Nov. 21.

Taiyo Yuden said the two Taiwanese firms infringed three patents regarding the manufacturing process for recording functions of DVD-R and had refused to pay patent fees.

Rieko Kimoto, TY spokes person, said the company estimates the amount of damage to be several billions of yen (about $1.8 million US), but declined to say how much it is seeking in the suits.
