Goodbaby and Mattel line up in battle over baby strollers

The Chinese baby stroller maker Goodbaby Group is planning to file a lawsuit in the United States against legendary US toy maker Mattel Inc claiming it infringed on patents for more than seven years.

The case centers around a multifunctional baby tricycle unveiled by the Jiangsu province company in 1997. It was later patented in many countries and regions including the US, Britain, Japan, Canada and Russia.

But in 2006, Goodbaby President Song Zheng found a three-in-one baby tricycle on sale in the US that has "similar designs" to his company's product.
