Eltek sues ZTE over high-efficiency tech patent

Norway-listed technology provider has taken legal action against the telecoms vendor, in its second recent move to protect its patents against another Chinese company.

Norway-listed Eltek ASA has initiated legal action against China's ZTE for infringing its patent on high-efficiency (HE) technology. The move is Eltek's second in recent months against a Chinese company.

In a statement Wednesday, the technology provider said it had developed its HE technology, which is utilized in power systems for telecom and other demanding industries, with all key design elements protected by patents.

Eltek added that it had been carefully monitoring the market for breaches of the company's patents.

"To keep up with our ambition of maintaining technology leadership, we have to make significant investments in R&D and in protection of the intellectual property of our design and ideas," said Morten Schøyen, chief marketing officer at Eltek.

He pointed out that Eltek had been in a dialogue with ZTE on the issue for a few months, but the Chinese firm did not admit to any infringement of its patent.

"As a result, we have to make the court decide. We have no doubt that we have a strong case and look forward to trying this in the Norwegian legal system," said Schøyen.

Eltek has started a legal offensive against several companies on patent infringement and intellectual property rights.

In November last year, the company announced that it is taking another Chinese company, East UPS, to court for illegally copying its products. That month, Eltek also won an injunction against Cambodian telecommunications company MFone for failure to pay US$3.73 million in outstanding service charges.

The Norway-headquartered firm specializes in telecommunications power and power electronics solutions for industrial applications and renewable markets such as solar power and electric vehicles.
