Dyson DC39

Samsung is taking well-known vacuum cleaner maker Dyson to court over a lawsuit that was ultimately dropped.

Last year Dyson sued Samsung over patent infringements specifically related to the Korean company's MotionSync allegedly infringing on patents from the DC37 and DC39 models. Dyson eventually dropped the case as evidence was uncovered that would protect Samsung, but this was the second such suit between them, the first of which Dyson won for around £600,000 (approx. $1 million USD).

On Sunday it appears that Samsung decided to head back into the courtroom with Dyson suing the company for 10 billion won (approx. $9.43 million USD) in the Seoul Central District Court. Samsung claims that the "previous litigation has hurt Samsung's corporate image," a Samsung spokesperson told the newspaper by phone. "Samsung's marketing activities were negatively affected by Dyson's groundless litigation, which is intolerable," they went on to add.

Samsung has stated that it is going to use this lawsuit as a teaching lesson for Dyson as the company has a record of litigating with its rivals.. An executive at Samsung is quoted as saying, "Samsung has the right to assess the damage the lawsuit has caused. Samsung is going to take a hard-line stance against patent trolls that use litigations as a marketing tool."

Dyson issued the following statement to Engadget regarding the newly filed lawsuit:

Dyson pioneered cyclonic vacuum cleaners and digital motors – and has been developing them ever since. We patent our technology, and naturally defend it. It is surprising that a company over 100 times bigger than Dyson is so worried. The patent system offers us some protection, but not enough: with an army of lawyers, hidden prior art is occasionally found and ways to design around existing patents identified.

This is of course amidst the ongoing laundry list of lawsuits between Samsung and Apple over numerous patents, and it makes you wonder if the Korean company may ever come after them on the same grounds.

It should be interesting to see how this plays out and if it does help prevent other companies from going after Samsung.
