Patent Infringement Background in the US

Fight illegal counterfeit!

We hold 15 patents on our  universal plug adapter invention in the U. S., and an even greater number of patents all over the world, including Canada, U.K., France, Germany, Saudi Arabia, India, Australia, China, etc. (please refer to our Patent page for a list of patents in 36 major countries).  Unfortunately, like the problem of music CD's and software CD's, there are a large number of  Chinese manufactures counterfeit our WA adapters in China.  Even worse, there are similar number of U.S. companies importing and selling those Chinese counterfeit plug adapters illegally here in the U.S. Of course, most of them violate our U.S. patent laws unknowingly because they were deceived by their Chinese counterfeit suppliers!  That's why we are here - we are here to educate the public, to fight the low quality counterfeit adapters with our high quality Wonpro adapters,  and to take legal actions against whoever chooses to continue to sell low quality illegal counterfeit plug adapters!
