Decompression algorithm LZW
The LZW algorithm itself, when used for compression or decompression in an apparatus (sic) designed for compression and decompression, has been patented by Unisys in Japan, Europe, and the United States. Fortunately, FreeSCI only needs LZW decompression, which means that it does not match the description of the apparatus as given above. (Further, patents on software are (at the time of this writing) not enforceable in Europe, where the FreeSCI implementation of the LZW decompressor was written).
