In a ruling this week, the judge said “all videos featuring Wolfoo” must be taken down before 16:00 BST on Monday.
Peppa Pig’s former owner Entertainment One and creators Astley Baker Davies Ltd originally took court action in London in 2022.
They claimed SConnect had attempted “to deceive the young Wolfoo viewership, most aged between two and five, into believing that Wolfoo is the same character as Peppa Pig” or connected to Peppa, the judge wrote.
The companies initially complained about Wolfoo’s appearance and artwork, but focused their legal case on the audio because they believed it would be easier to prove certain sound clips were directly copied.
The evidence of “copying of the audio clips is compelling”, the judge decided.
“That copying was extensive, seemingly endemic at least so far as the English language Wolfoo videos are concerned.”
SConnect said an independent third party contractor had provided sounds from Peppa for use in Wolfoo videos without their knowledge.
They said all infringing videos were removed, and that new Wolfoo animations made after mid-2020 used only voices and sounds that were created in-house.
However, the judge said the fact the sounds were supplied by a third party was “irrelevant”; that while many infringing videos were removed, some were simply moved to other channels; and that the claim that all new sounds were recorded in-house “can be disproved”.
News has asked SConnect for comment.
The judge said clips from Peppa Pig were found in all 92 English-language Wolfoo videos that were examined, and about 75% of the foreign-language videos.
