- I'm somewhat concerned about the possibility that some Linux developers
- might be familiar with AT&T code. For legal reasons it might be best
- to make sure that all Linux kernel code is developed by people with
- no prior experience with AT&T code.
-
- Actually, what's really important is whether or not Linux developers had
- access to AT&T code under a source license which contains the words
- "methods and concepts". What "methods and concepts" says is that the
- licensor owns the "methods and concepts" used in the source code as
- intellectual property, and if you ever write code that uses those same
- "methods and concepts", the licensor owns it.
-
- Fortunately for me, MIT as an institution refuses to sign _any_ license
- which contains a "methods and concepts" clause. You may want to check
- the agreements you or your company have signed to see if they have that
- deadly clause.
-
- It may also good idea to make sure we don't use any significant pieces
- of code from the BSD networking release, just to be sure, although I
- doubt Linux is under any serious threat, since it isn't a commercial OS.

- P.S. Food for thought: apparently IBM holds a patent of emulating the
- 'Tab' character on a VDT screen. IBM normally doesn't enforce it,
- although apparently Microsoft paid a fair amount of money to IBM to
- settle patent enfringements of this nature.
-
- Also, AT&T owns the patent on backing store, and was attempting to
- collect $25 for each X server that used backing store. MIT (on behalf
- of the X consortium) is currently fighting AT&T in court on this issue.
- Sigh.... what else did you expect from a company whose logo is the Death
- Star? :-)
