I personally wrote an implementation of lzw in Assembly in my late teens. It could deal with gifs... that was before 1999, when
Unisys[0] claimed the patent (for all kind of uses) and had the patent for many a year, PNG was created not to use lzw since it was patented. The algorithm was patented for the encoding part but not decoding.
