New York: A judge ruled on Monday in favour of Harry Potter author J.K. Rowling in her copyright infringement lawsuit against a fan and website operator who was set to publish a Potter encyclopedia.

US District Judge Robert P. Patterson said Rowling had proven that Steven Vander Ark's Harry Potter Lexicon would cause her irreparable harm as a writer.

The judge permanently blocked publication of the reference guide and awarded Rowling and Warner Bros Entertainment Inc $6,750 (Dh24,773) in statutory damages.

No original insight

"I took no pleasure at all in bringing legal action and am delighted that this issue has been resolved favourably," Rowling said Monday in a statement.

"I went to court to uphold the right of authors everywhere to protect their own original work. The court has upheld that right.

"The proposed book took an enormous amount of my work and added virtually no original commentary of its own ... Many books have been published which offer original insights into the world of Harry Potter. The Lexicon just is not one of them."
