Is there any page that manages into or try to summarize the milestones
in the degeneration of copyright, patent and, in general, intellectual
property laws?

With "milestones" I mean any sensitive change in
copyright/patent/intellectual property laws such as:

- extension of the duration of copyright

- extension of the works on which copyright is appliable

- the first time a genetic sequence has been patented


But I also mean "abuses" of these laws commited by publishers and
copyright/patent holders in order, for example, to censor
undesiderable contents or to damage business competitors.


I'd like to know if there is a page (or more pages) that collects this
events (mainly the sensitive changes in the laws) and, optionally the
date in which they occurred.



Thanks in advance.

Best regards.
