Known as 'fair dealing' in the UK, this legal term is used to establish whether a use of copyright material is lawful or whether it infringes copyright. Fair dealing allows an exception to use copyrighted materials in academics (non-commercial research, private study and illustrations for teaching purposes), criticisms or reviews, news reporting and parody.
If you believe your copyright has been infringed it is best to discuss the case with an intellectual property lawyer. There is no statutory definition of fair dealing, to what degree your copyright has been infringed is decided by a number of factors and therefore has to be judged case by case.
