Proview began developing its own "iPAD" device, a Windows-based computer, in 1998, according to Yang. But the product failed to take off. When the company entered talks to sell off some of the iPad trademarks, IP Applications repeatedly promised they would not be used to compete with Proview's electronic products, Yang said.
Proview now plans to file legal action against Apple in the U.S. for using a "fake company" to mislead Proview in selling off the iPad trademarks.
Apple spokeswoman Carolyn Wu declined to offer new comment.
