LAME makes clear that it is *not* an MP3 encoder but that it produces 
compatible files in a comparable format. Apparently that was sufficient 
to defeat the Fraunhofer Institute's claim of patent infringement.

The decoder is 'standard' in that the algorithm is in the public domain. 
Its implementation can (and does) vary, often with disappointing 
results. At one time, WinAmp used an implementation which attempted to 
extend the high-frequency response; its amplification of artifacts made 
it short-lived.
