Just a quick read of copyright / patent infringement enforcement in the PRC (people's republic of China) info from a few websites will give you an idea of how a lawsuit will do nothing but cost ecotech, or maxpect money and do nothing to deter jebao.
I thought this little excerpt was particularly funny:
In March 1992 Chinese authorities found that Shenzhen reflective materials institute had copied 650,000 Microsoft Corporation holograms. The institute was found to be guilty of trademark infringement against Microsoft, but was fined a mere US $252. Losses to Microsoft as a result of the infringement are estimated at US $30 million.[8]
I am a fan of jebao and use their wp, rw, dc pump, and doser. And I for one hope they keep making and improving products and selling them to us hobbiests at amazingly cheap prices.
