Wolverhampton Wanderers are being sued by a pensioner who claims he designed their crest when he was a schoolboy.
Peter Davies, who is in his early 70s, says he drew the emblem - featuring the head of a wolf - in the 1960s and entered it into a competition run by an art gallery in the West Midlands city.
He has taken his copyright complaint to the High Court, arguing he composed sketches that would become the Wolves badge after a teacher asked him to demonstrate an understanding of hexagrammum mysticum.
The theorem, composed by French mathematician Blaise Pascal, states that if a hexagon is inscribed in a circle, then each of the three pairs of its opposite sides intersect at a trio of points lying on a straight line.
Mr Davies, a former building industry manager, says his understanding of the geometric theory led him to create the animal icon that would later be adopted by Wolves.
Bosses at the football club dispute his claim and lawyers tried to get the case thrown out last year, arguing there was "no reasonable cause of action".
But Mr Davies - who says he recognised the design in 1979 and applied to register it in 2016 - has managed to get it to court and Mr Justice Nugee will analyse evidence and legal argument over four days.
The case got under way on Thursday morning.
