A dispute over a cross-licensing agreement between two major electronic manufacturers has spilled over into the Delaware Court of Chancery, with Sanyo Electronic Co. accusing Intel Corp. of improperly claiming the rights to its intellectual property.

The lawsuit, filed on Oct. 7 by attorneys from Norton Rose Fulbright‘s Los Angeles and Austin, Texas, offices, was made public on Wednesday. According to the 37-page redacted complaint, Sanyo and Intel had tried to work out their differences for a year, but the talks went nowhere, sending the parties to litigate their claims before Vice Chancellor Morgan T. Zurn in Wilmington.
