Silicon Labs cleared of patent charges

Silicon Labs announced that the U.S. International Trade Commission (ITC) found no TV tuner patent violation by the company or its customers in an investigation that began in early 2014.

In a statement released by Silicon Labs, the ruling affirms a previous finding by the Administrative Law Judge (AIJ) that all patent claims asserted against the Texas-based company's silicon TV tuner products are either invalid or not infringed.

Cresta Technology filed a complaint that started the investigation in February 2014. The California-based company alleged that Silicon Labs and several of its customers infringed three patents related to TV tuners. Cresta subsequently withdrew one of the patents.

After a hearing and review, the ITC found that there was no violation committed by Silicon Labs or its customers and that all patent claims asserted by Cresta were either invalid, not infringed or both.

In addition, the ITC found that Cresta failed to satisfy the governing body's industry requirement for each patent, resulting in a separate and independent basis for the finding of no violation.

"We are pleased that the ITC agreed with Silicon Labs and its customers that Cresta's claims were without merit," said James Stansberry, senior vice president of Silicon Labs' IoT (Internet of Things) Products. "This finding is good news for our customers and for the consumer broadcast industry. Silicon Labs vigorously defends itself against all unjustified allegations of infringement."

In May 2014, Silicon Labs also filed a complaint against Cresta and four other companies for allegedly importing and selling certain silicon tuners and products that infringe one or more claims of U.S. Patent Nos. 6,137,372 and 6,233,441.

According to a filing with the U.S. Securities and Exchange Commission, Silicon Labs posted a $620-million revenue last year, earning profits worth $38-million or 87 cents per share. The previous year, it had revenue of $580 million, with a profit of $49.8 million or $1.14 per share.

Founded in 1996, Silicon Labs develops silicon, software and system solutions for the IoT, Internet infrastructure, industrial automation, consumer and automotive markets. It currently has 600 employees working in its two Central Texas offices.
