The LAME developers stated that, since their code was only released in source code form, it should only be considered as an educational description of an MP3 encoder, and thus did not infringe any patent in itself. They also advised users to obtain relevant patent licenses before including a compiled

Around mid-1998, Mike Cheng created LAME 1.0 as a set of modifications against the "8Hz-MP3" encoder source code. After some quality concerns raised by others, he decided to start again from scratch based on the "dist10" MPEG reference software sources. His goal was only to speed up the dist10

LAME was required by some programs released as free software in which LAME was linked for MP3 support. This avoided including LAME itself, which used patented techniques, and so required patent licenses in some countries. All relevant patents have since expired, and LAME is now bundled with

version of the encoder in a product. Some software was released using this strategy: companies used the LAME library, but obtained patent licenses.

This is what made it possible for modern MP3 encoders (e.g. LAME) to improve far beyond the original L3enc and dist10 reference implementations.

May 2000 (LAME 3.81): the last pieces of the original ISO demonstration code are removed. LAME is not a patch anymore, but a full encoder.
