Chimei Innolux sues Sony in US and China

Chimei Innolux has upped the ante in its ongoing war with Sony filing new lawsuits that claim Sony has infrginged several of its patents.

The TFT-LCD display maker has accused Sony of violating three of its patents, using the patented technology in a number of high-profile Sony products, including the Playstation 3 console, Sony Bravia LCD TVs, Vaio notebooks and Cybershot digital cameras.

Chimei Innolux has already sued Sony as recently as the 7th of July when it said it wanted to “halt the sale and demand compensatory damages over a wide range of Sony products that infringe [Chimei Innolux’s] patented inventions.”

It filed its latest lawsuits in both the US and China on Monday and wants monetary compensation for the patent infringement. The lawsuits cover many of the same products of its earlier case, but the company said that neither cases are “specifically related”.

The lawsuits are also a direct response to ones taken by Sony in March against Chimei Innolux and a number of other companies over patent infringement relating to digital TVs and monitors, which Sony brought to the International Trade Commission (ITC) in the US.

That was the least of Chimei Innolux’s problems as the Attorney General of Arkansas has recently stated his intention to join the Attorney Generals of four other states in suing Chimei and other LCD manufacturers over allegations of price fixing.

TechEye spoke to Bob Raikes, principal display analyst at Meko, who told us that Chimei Innolux “is, of course, owned by Hon Hai which also owns Foxconn, which is a major TV supplier to Sony and recently took over the Slovakian and Mexican TV factories of Sony, so that could cause interesting inter-company tensions.”
