The Productivity Commission has recommended the free import of books, the free use of copyrighted material under new so-called "fair use" rules, a leglislated guarantee that consumers have the right to defeat internet geoblockers and much tighter restrictions on the granting and use of patents, under reforms it says could save consumers up to $1 billion a year.

Consumers should also have a legislated right to defeat internet geoblocks set by such companies as Amazon, it says.

Subtitled Copy(not)right, the draft report of the commission's nine-month inquiry into intellectual property finds copyright terms are way in excess of what is needed, offering more than 100 years of protection for works that ought to be protected for 15 to 20 years.

It says the typical commercial life of a book, film or piece of music is less than five years, but that Australia's copyright rules often grant 120 years, which is the life of the author plus 70 years.
