The philosophy of copyright considers philosophical issues linked to copyright policy, and other jurisprudential problems that arise in legal systems' interpretation and application of copyright law.
One debate concerns the purpose of copyright. Some take the approach of looking for coherent justifications of established copyright systems, while others start with general ethical theories, such as utilitarianism and try to analyse policy through that lens. Another approach denies the meaningfulness of any ethical justification for existing copyright law, viewing it simply as a result (and perhaps an undesirable result) of political processes.
Another widely debated issue is the relationship between copyrights and other forms of "intellectual property", and material property. Most scholars of copyright agree that it can be called a kind of property, because it involves the exclusion of others from something. But there is disagreement about the extent to which that fact should allow the transportation of other beliefs and intuitions about material possessions.
There are many other philosophical questions which arise in the jurisprudence of copyright. They include such problems as determining when one work is "derived" from another, or deciding when information has been placed in a "tangible" or "material" form.
Legal scholars often approach copyright in search of a coherent ethical justification for its existence and character. This approach may seem to be backwards—it might make more sense to start with an objective and then examine the law against it—but it is widely practised. Thus, the normative or ethical theories that might naively be regarded as tests for copyright law to pass are often called "justifications" of it. Justifications for copyright can generally be approximated into two groups: deontological or consequentialist. Deontological justifications for copyright seek to justify copyright as a matter of rights or duty; they seek to assert a justification for copyright (or intellectual property more generally) on the basis that it is morally correct to do so. Contrariwise, consequentialist theories of copyright seek to justify or criticise copyright protection based on the consequences of that protection, by asserting or providing evidence that the protection of copyright produces some desirable effect. Examples of such theories include incentives theories that view intellectual property as a necessary way of incentivising the creation of new creative works.
