Intellectual Property rights and copyright Constitution, Article 1, Section 8 “The Congress shall have power…to provide for the …general welfare of the United States To promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries; (emphasis added)
What has copyright become? Licensing is replacing copyright in the digital age Moving long standing common law or constitutional rights into the arena of person to person business transactions, where these rights no longer apply. Examples, international arena, increasing time before work enters the public domain Fair use is disappearing
Public domain: Why should we care? What’s part of Public Domain? Still isWas AirWater SunlightLand Numbers God Ideas & Facts* Resources freely available, without permissions or fees needed, and no tracking of what you read or use - all for society to do what they want with them.
Importance of Public Domain Common Heritage (philosophical) New Knowledge incorporates Old (progress) Derivitative works rely on pre-existing works (creativity) Social Commentary (free speech)
What this means Dismantlement of the public sphere in general - controlling social/political commentary & satire. Criminalizing acts that might impede digital commerce. Controlling access to older information (our history). Makes the Internet a commercial venture, not for production of ideas. Diminishment of exploration & experimentation. Challenges Democratic values (that anyone can be a creator)
