Cachebox TV t/a SafeCast is a British-based technology company, which was founded in 2013 by Alistair and Diana Kelman. The company was created following the grant of a UK patent. The creation of Cachebox TV allows investors to invest in the overall development of the patent, licensing and also the eventual deployment.
Transferring ownership of the patent to the company allowed investors to benefit from the Seed Enterprise Investment Scheme (SEIS) tax break, along with benefits of the Patent Box for any exclusive licensee of the patent from the company.
The UK IPO granted the patent on 22 October 2013. The patent (GB2498499) was entitled “System for providing improved facilities in time-shifted broadcasts”. A summary of the patent is that it ensures inappropriate advertisements are not shown to children or vulnerable people. This is achieved by the inclusion of tags or metadata within television advertisements and automatically processing them in the TV set or set top box, substituting appropriate advertisements for inappropriate advertisements. The technology is of universal application and can be deployed in browsers and in IPTV too.
Following the publication of the patent, Cachebox was first discussed in The Sunday Times on 4 May 2014. The article in The Sunday Times studied the possibilities for TV advertising, as the writer suggested it currently didn't do enough to protect children or vulnerable people from certain advertisements.
On April 7, 2015 Cachebox registered Safecast as a trademark at the UK Trade Mark Registry. The company intends using Safecast as the name for its forthcoming service.
On June 17, 2014, HMRC provisionally approved Cachebox as an SEIS investment vehicle. Its inventor and company co-founder, Alistair Kelman, formally assigned the patent (GB2498499) to the company in August. Around the same time the company appointed a co-director, Henning von Spreckelsen.
On 12 July 2016 the United States Patent and Trademark Office granted the Cachebox patent and gave it U.S Patent No.: 9,392 302.
On 1 January 2017 Cachebox revised its website and began trading under the name SafeCast, its UK registered trade mark.
On 16 November 2017 SafeCast published a video submission to the DCMS Internet Safety Strategy Green Paper on YouTube entitled "Age Verification - Protecting Children on TV and the Internet". The 25-minute video addresses the section of the Green Paper on “Technological Solutions to Online Harms” and makes reference to the NIST SP800-63 Digital Identity Guidelines which were published in June 2017. This was the first time in history that that a UK Government Green Paper was responded to by means of a video.
