Chocolate giants Nestlé and Cadbury have clashed over the shape of Kit Kat bars.
Nestlé have gone to court to try and trademark the three-dimensional shape of a Kit Kat finger, but Cadbury, based in Birmingham, is objecting.
Mr Justice Arnold is currently waiting on a decision from a European court relating to the dispute. He said:
"Certain aspects of the relevant law remain unclear.
"I have decided it is necessary to seek clarification of the law from the Court of Justice of the European Union in order to determine the (dispute)."
This is not the first time the rival companies have had legal disputes. Nestlé successfully overturned a courts decision to allow Cadbury to trademark the colour purple used in its famous 'Dairy Milk' chocolate bars.
The number of apprentices in the Midlands has increased by more than ten per cent in the last year, according to the National Apprenticeship Service.
Mondelez, which owns Cadbury's, is one employer in the Midlands investing in apprenticeship schemes. It's predicted within ten years, the number of apprentices will rise by 85 per cent, which the government says will help rebuild the economy.
Birmingham-based confectioners Cadbury has insisted it is not trying to trademark "50 shades" of purple after coming under fire from a Church of England bishop over rights to use the colour.
The company said its victory in a dispute with rival Nestle over purple packaging did not amount to a bid to copyright all shades of purple - but merely to protect the Cadbury purple associated with its milk chocolate.
"We are not seeking to trademark 50 shades of purple, it is about making sure that the consumer is not confused into thinking this is a Cadbury product - that is the nature of a trademark," a spokesman for Cadbury said.
