dbh- thanks. I think many have hostility against patents and copyright due to the way big companies use government to enforce against private individuals and children.
My opinion- yes, the enforcement has often been aggressive, heavy handed and intrusive.
But it does not invalidate the concept of property ownership of the products of imagination, effort and creativity.

Just brilliant, db! I wish I could meet you up in NH. Hopefully by then I will be done with your book.
