Sale of Design IP rights

Hi, I am a self employed designer who has been designing products for a company for many years and receiving royalty payments on each of my designs. The company would now like to buy from me the intellectual property rights for my designs. Would the sale of these IP rights be a disposal of an asset and therefore be classed as a capital gain for tax purposes?

Hi tj1852
Yes this would attract Capital Gains Tax (CGT). 
Guidance is available at: CG68000C - Capital Gains Manual: Goodwill and Intellectual Property Rights: contents - HMRC internal manual 
Thank you
