A musician who made a 10-hour long video of continuous white noise - indistinct electronic hissing - has said five copyright infringement claims have been made against him.
Sebastian Tomczak, who is based in Australia, said he made the video in 2015 and uploaded it to YouTube.
The claimants accusing him of infringement include publishers of white noise intended for sleep therapy.
In this case, those accusing Mr Tomczak are not demanding the video's removal, but instead the reward of any revenue made from advertising associated with it.
Without the claims, Mr Tomczak would receive such revenue himself.
"I am intrigued and perplexed that YouTube's automated content ID system will pattern-match white noise with multiple claims," he said.
His video was originally made along with other 10-hour recordings - including one of a continuous electronic tone.
The claims relate to specific portions of similarly lengthy videos of white noise also posted on the site.
Mr Tomczak said the "spurious" claims won't have a significant impact on him, though he finds them "frustrating".
"If I were making substantial money from YouTube content, such a broken system may prove to be unusable," he said.
Similar cases have occurred before. In 2012, one YouTube user reported that he faced copyright claims over birdsong captured in the background of one of his videos.
On that occasion, a spokesman for the claimant in question said the claim was indeed made by YouTube's automated system.
The claim was soon removed.
"Copyright does not protect the idea, but the expression of the idea," explained intellectual property lawyer Iain Connor at UK law firm Pinsent Masons, reports BBC.
