The BBC has told a 'Doctor Who' fan to stop making knitting patterns based on the TV series.
The fan, who does not want to be named but calls herself Mazzmatazz, has never sold her patterns but was contacted by the BBC after some of them ended up on eBay.
The patterns enabled knitters to create small toys similar to Dr Who monsters.
The BBC has denied initiating legal action, and told PA: "We sent an email from our brand protection team asking her to remove the patterns from websites because she didn't have permission to use them.
"If it's on a small scale, for the fans and not for profit then we let the matter rest.
"But this had crossed the line into a profit-making exercise by third parties that wasn't going back to the licence fee payer."
The Open Rights Group, which advocates for civil and consumer rights in the UK, has supported the 'Dr Who' fan.
A spokeswoman said: "We need to recognise that there is a difference between selling knock-off handbags in the market, and fans who are making tributes and contributing to creativity in the future."
