Aqualiner has a patented process for renewing aged water pipes without the need to dig up the pipes. Since 2007 Aqualiner has developed a fourth generation of fully process controlled equipment capable of producing liners in water companies live infrastructure. During 2016 one of the key objectives was to file one or more patent applications on aspects of the design of a new heated pig, thereby providing a further 20 years’ patent protection. Ultimately Aqualiner’s real value, both commercial and financial lies in its intellectual property. The original patents are licensed to Aqualiner under an exclusive agreement. By making patent applications in the name of Aqualiner on the opportunities for process improvement we enhance the value and duration of our own IP portfolio and improve the speed, efficiency and controllability of our process. Aqualiner received confirmation from UK Patent Office of the grant of its first Patent (GB2554431) in July 18. A second patent application (1802664.1) was filed in February 2018. Aqualiner has raised £6 million through a series of equity issues and has to date received two independent offers to buy the business from international public companies. One in 2010 for $21 million and in 2014 an offer based on an earn out basis. The latter was turned down by the shareholders.
