Agreed. And in fact I did not suggest to get patents for Sage.

However, when I recently helped my son in a school project on the
invention of the telephone, I was on the one hand amazed how different
the story is told in the German and in the English Wikipedia.

And on the other hand I was shocked that, at least according to German
Wikipedia, Bell used his patent to prevent other people from further
developing the telephone -- even the people who presented the
telephone in the USA several years before Bell had a working model on
his own.

Now translate it to 2009. I don't  know how the law is today. My
question:
Would it be possible for (just as an example) Wolfram to get patents
for known algorithms *and* forbid other people to further develop
these algorithms? Would it be possible to get a patent on the
manipulate/interact feature, even though it was openly available since
at least 2002 or even <1999?

If this were the case, then wouldn't it be worth to spend some money?
-- Not to get a patent, but in order to prevent people from getting a
patent who don't deserve it!

Cheers,
Simon
