Patents now last 20 years from filing date; that was part of the GATT
agreement. This retroactively applies to extend but not decrease the life
of a patent. In the case of LZW, I think it adds 1 or 2 years (I can't
remember the filing date offhand).

This is according to an attorney friend of mine, so it's just hearsay. I
am not a lawyer.
