If you write a song, and the melody is very similar to that of a song
you have heard, you very well may be sued if your song becomes popular.
Fortunately, this does not happen very often. However, the precedent of
George Harrison shows that copyright infringement need not be conscious
to be actionable. You can be sued if you were exposed to the original
work and there's a substantial similarity.

Not hiring programmers who had worked with 8088 assembler before was
probably not necessary. However, it demonstrates the extreme precautions
Phoenix took to avoid lawsuits from IBM, which was litigious and
had almost infinitely deep pockets. Phoenix wanted to be able to
indemnify its customers against copyright infringement suits to
encourage them to use its products.
In the case of WINE, exposure to documentation of the APIs is likely
to be OK. Why? Because application programs written by programmers
exposed to these materials are generally not considered to be
However, exposure to the source code of a program whose copyright one
could be accused of infringing (in the case of WINE, this would be the
source of Windows itself) would definitely NOT be OK. This is why
one cannot read (L)GPLed code and then write commercial programs.
The FSF is likely to be a nasty litigant, and gets its legal services
for free. It would gladly bankrupt you if it would mean wiping out a

No. But the author who sued J.K. Rowling had written books which featured
creatures called "muggles" and a dark-haired boy named -- I'm not making
this up! -- Larry Potter. If Rowling did NOT (consciously or unconsciously)
copy this author's work, it would be an incredible coincidence.

Quite a few. But even more often, threats are made and people who cannot
afford to go to court are forced to back down. These cases seldom make
