NEW YORK (CNN/Money) - A children's hospital in London may be poised to pick a fight with Walt Disney Co. over the rights to "Peter Pan."

Great Ormond Street Hospital is talking to its lawyer about whether a prequel to the original novel infringes on the hospital's ownership rights to the book, a hospital spokeswoman confirmed. Disney published the prequel in August.

The book at issue is "Peter and the Starcatchers," written by syndicated humor columnist Dave Barry and crime-novelist Ridley Pearson.

The hospital uses the millions in royalty fees it collects from "Peter Pan" to support the medical center and treat sick children, thanks to J.M. Barrie's decision to donate the rights to the hospital's charity before his death in 1937, the New York Post reported Tuesday.

"The Walt Disney Company has a longstanding relationship with Great Ormond Street Hospital in the UK, which includes continuing to pay substantial royalties for usage of Peter Pan by Disney in countries where the copyright remains in effect and we will continue to support their excellent work," said Disney's vice president of corporate communications John Spelich in a statement.

"A unit of the company is publishing 'Peter and the Starcatchers' only in the United States and Canada, where J.M. Barrie's Peter Pan stories are in the public domain," said the statement.
