Inventor of the World Wide Web, Sir Tim Berners-Lee is up against innovators from business, science, art and design in a competition to find the UK's favourite 'British Visionary Innovator'.

The competition, run by the Intellectual Property Office to celebrate World Intellectual Property Day 2012, aims to celebrate people who have achieved considerable success or developed innovative products, services or designs.

The current shortlist drawn up by the IP Office's business outreach team is dominated by innovators in the technology and science space.

For example, Berners-Lee is up against Michael Aldrich, who invented the origins of online shopping (Teleputer) and has worked on high-profile IT projects for the NHS, British Rail and Ford; James Goodfellow, who invented personal identification (PIN) technology and the cash machine (ATM) and Apple products designer Sir Jonathon Ive.

Industrial designer Sir James Dyson and Sir Ian Wilmut, the scientist famous for his achievements in cloning Dolly the Sheep were also on the list.

Other innovators shortlisted include Harry Potter author JK Rowling, TV producer Simon Cowell and graffiti artist Banksy.

The shortlist is not exhaustive, however, and the public has been invited to nominate their own visionary innovator.

Voting has opened today and will end at 5pm on 24 April - cast your vote now.
