The lawsuit had alleged that OED's German customer, TrekStor GmbH, had infringed two E Ink patents on electrophoretic displays in e-book readers. The case followed the Chinese e-paper producer's success in Europe where its sales had surged.
"OED's high sales in Europe, especially in Germany, raised E Ink's concerns about possible loss of market share," said Chen.
It took nearly more than two years for OED to successfully defend its customers' right to use its e-paper display panels.
"As a young company, we needed to offer our full services and support to our customers. So we were active in helping defend ourselves against the lawsuit," said Chen.
"After a thorough analysis by our German attorneys and technical experts, we considered the lawsuit to be wholly without merit as we had already developed dozens of patents of producing and selling the e-paper display panels."
In February 2015, the Federal Patent Court in Germany ruled E Ink's lawsuit was invalid.
"Winning the lawsuit helped greatly expand our overseas sales. The global e-paper display market will change in the near future. We have plans to ship more products overseas," said Chen.
According to him, the company's products have since been sold in the Netherlands, Belgium and Italy.
"The years-long lawsuit has not affected our business and our clients. TrekStor's marketing and sales of its E-Book readers are running as usual," Chen said.
OED is now gearing up to supply its products to some top makers of home appliances in South Korea, including LG and Samsung.
