This text explores the foundations of UK copyright law under the Copyright, Designs and Patents Act 1988, emphasizing that copyright protects the expression of ideas, not the ideas themselves. It covers originality, fixation, and categories of works (literary, dramatic, musical, artistic, sound recordings, films, broadcasts, and typographical arrangements). Key cases like Interlego v Tyco, Walter v Lane, and Norowzian v Arks illustrate challenges in defining originality and artistic craftsmanship. The study highlights gaps in protection, debates over format rights, and the balance between safeguarding creativity and public interest.
