Thanks. While I can be obsessive at times, in this case most of it was written before.

I have been planning to write a piece on patents and copyrights for a while and have made a lot of notes. Writing this involved organizing the notes and removing most of the copyright stuff, which is not ready.

Copyright is a bit more complicate to address since many Libertarian thinkers, such as Freedman and Rothbard, defend it.
