I see, and many thanks for the link. The one thing it doesn't explain
however, is why the USTPO allowed 2 different entities to patent the
lzw algorythm. That is still a puzzlement to me, but what do I know.
Umm, I haven't read them, nor am I a lawyer. However, I took a short
course in "Intellectual Property Law" a few years ago, and learned a
little something, and this is my understanding.
One does not patent algorithms, whatever you may have read or
heard. Patents are issued for exactly two things: processes and
devices. Now these terms are pretty broadly interpreted. For
example, a mouse with a particular set of genes may be a device.
So, the mathematical algorithm, in the sense of means of computation
of a given result, is not patentable. What is patentable is the
application of a given algorithm to create a process. For example,
the computations involved in computing the LZW compression of any
given stream is not patentable. But the application of that
computation to the compression of a video image *is* patentable.
So the same algorithm, if it is applied in different ways, may
result in more than one patentable process.
So this may be an answer to your question.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
