Kodak gets Japanese patent

Eastman Kodak Co. said it received a Japanese patent for commonly used video recording technology, strengthening attempts to collect as much as $1 billion in royalties from camcorder makers.

The approval earlier this month from a Japanese patent office follows a federal lawsuit Kodak filed against Sony Corp. and Sony Corp. of America. Kodak claims that the recording heads Sony puts in its videocassette recorders and camcorders copy technology that Kodak patented in the U.S. in 1981.
