The first plaintiff, Mukono Family Trust, claimed to have registered certain industrial designs for surge protectors (described as double or triple path transient protection devices) on 31 July 2008 under registration number ID 7/2008 in terms of the Industrial Designs Act [Chapter 26:02]. The certificate of registration was issued in the name of Mukono Family Trust for a period of 10 years. An electrical and electronics engineer, Lovemore Mukono, testified that he designed the industrial design and after reaching a commercial state of development, assigned it to Mukono Family Trust through a deed of assignment. The plaintiffs alleged that the defendants infringed their exclusive rights by making, importing, selling or offering for sale articles that copied the registered industrial design, including the metal box dimensions, electronic circuit diagram, and copyrighted words "The Power Surge Stops Here." Initially seven defendants were sued, but claims against all except the first defendant (Karpeg Investments) were withdrawn at various stages. It was common cause at the pre-trial conference that the industrial design was registered in the name of Mukono Family Trust.
