Back in the 1950s Donald Shepherd had the inspired idea of using Porta as a prefix for his portable products. With an eye to the future, the prefix was secured as a registered trademark that now covers Portakabin and its products.


Portakabin has built up a series of PORTA- prefixed trademarks that distinguish its products, and the company has built its reputation in the UK based on this family of marks.
