Ernst and Young said it "cannot conclude that certain employees of WIPO and third parties concerned might have committed any fraud or dishonest acts."
In September, Kamil Idris, director-general, WIPO asked Ernst and Young, the international audit and consultancy firm, to conduct an independent external review, under the supervision of WIPO's external auditor, the Swiss Federal Audit Office, into the allegations.
In its report, Ernst & Young makes a number of recommendations to the Organisation but does not support any of the allegations made in the news media, WIPO said.
It said on Wednesday that the Ernst and Young report "brings to an end the recent allegations and unfounded attacks on the Organisation that have appeared in a few news media."
