This section will cover other significant copyright issues that are at stake today and require a struggle.
The first is the lengthening of the copyright term. Recently the Sonny Bono Copyright Term Extension Act that was passed in American congress extended the copyrights act by 20 years. One should note that the term was already extended several times in the past, since the first American copyrights law. 95 years for a copyrights of works of corporations is far too long, and we also risk that copyrights will be extended indefinitely this way.

A different issue is the Digital Millennium Copyright Act (or DMCA for short). This law that was passed in the 90's criminalises a lot of valid activity. It prohibits the writing of "circumvention devices" to bypass copyright protection (and some say every computer security measure, in general). It is actively used to threat to remove allegedly copyrighted content from web sites, because they may violate it. (See Cory Doctorow's excellent essay "Save Canada's Internet from WIPO".) It also contains a lot of other damaging clauses.
The Free Expression Policy Project has an excellent report on the various issues in copyrights law in the past and today. It is a very recommended read.
The Electronic Frontier Foundation has many resources related to activity against various harmful copyrights regulations.
