[Leaplist] Patent Infringement

[Jim Hartley]

A textbook is generally copyrighted, not patented. For the kind of thing 
you mention, the author is often using old material that is in the 
Public Domain, but a "novel presentation" might be covered by the 
copyright. If the author were to actually present patented material 
(legally), he would have to first, get permission from the patent 
holder, and then mark the material ("Reg US Pat OFF" or something like 
that, and I think the patent number).

A math book is unlikely to have anything patented in it. An engineering 
text might. A computer science text, except for the incredible stupidity 
of the US Congress, the US Courts, and the USPTO, should be like the 
math book and have NOTHING patented in it.
