Carl Ichan Sells Stake in Wilsonville's Mentor Graphics

Five years after Carl Ichan tried to break up WIlsonville's Mentor Graphics - an effort that he abandoned after taking control of 15 percent of the company and installing some of his own people on the board of directors - he has moved on.

Ichan sold his stake in Mentor, one of Oregon's largest technology companies, according to The Wall Street Journal.

The paper says that the sale was part of a larger selling off by the investor who, they say, has been "pessimistic on the stock market."

Icahn first bought into Mentor, which employees about 1,000 people at its headquarters in Wilsonville, in 2010.

The following year he launched an effort to split up the company, something he abandoned after getting three people on to the company's board of directors.

Mentor stock was down Tuesday morning.
