Flat screen maker Samsung Electronics has sued AU Optronics Corp. and three of its US based customers for allegedly infringing patents related to some of its key display technologies.
The Korean electronics giant filed the complaint with the ITC (International Trade Commission), US, and it stated that AU Optronics was illegally using their patented technology in its own LCD product, the Suwon.
Adding more worries for the Taiwan based Au Optronics, Samsung filed more lawsuits against the company with federal courts in California and Delaware.
"To protect its investment and customers, Samsung has -- and will continue -- to take action against any unauthorized use of its patented technology," Samsung said in a statement.
The three clients that also were at the receiving end of Samsung’s decision to go legal are Sanyo Electric Co, Acer and BenQ Corp.
Earlier last month also, Samsung filed a similar lawsuit against Apple Inc. where it accused the iPhone maker of infringing their patents on some key product-designs.
Meanwhile, AU Optronics is currently reviewing the matter for deciding on the legal approaches to be taken for securing the interest of the company, as well as of its customers, a spokeswoman of the company said.
