Here is part of Shawyers most recent presentation and his patent application.
First generation emdrive- Original low thrust technology for inorbit satellite applications. Reported to be operational in US and China. NASA eagleworks has a peer reviewed report of 1.2 millinewtons per kilowatt of thrust from a first generation emdrive.
Second Generation emdrive
High thrust, low acceleration, superconducting technology. Space and Marine applications.
Under development in UK and US. Nextbigfuture notes that no report of a superconducting Emdrive having official performance measurements. If a superconducting Emdrive works as claimed then the amount of thrust would be definitive.
