All of those examples are trivial,
they're all the same algorithm. I merely picked one of the more terse, which really has nothing to do with triviality.
Seriously, read that.
You're calling it trivial with over 30 years of advancements in computer science behind you.
Yes, of course I fucking can. The ability to do that is part of what makes a "person having ordinary skill in the art" an important concept. Even 30 years ago LZW represented an incremental improvement on the current state of the art.
Regardless of the novelty of the idea, LZW has always been trivial to implement.

I am not arguing that it fails the usefulness test, nor that it was not important.
Your "this looks like a pain in the ass to implement" defense of the patent is absurd. You clearly would support the patent regardless, since you seem to be fine with the LZW patents.
