Patents
The patents owned by the parent company GoldSpirit Investment Pty Ltd and Vuestar Technology Pte Ltd were all registered under the name of inventor Ronald Langford, including US 7065520, AU 755035 and Singaporean patent 95940. The Australian patent has ceased through failure to pay a renewal fee due in October 2007, according to the IPAustralian patent database. EP application 1327207 was also filed but lapsed through failure to pay a renewal fee before the European Patent Office had conducted their own prior art search.
All of these patents originated from WO application 0229623 which was searched and examined by IP Australia who were unable to identify any particularly relevant prior art. The patents in Australia and Singapore were therefore granted without significant limitations to the claims. The US patent was granted only after further examination by the US Patent and Trademark Office resulting in additional limitations being added to all of the independent claims as granted including that: "the visual content comprises a plurality of mini-images in the form of a conveyor belt slide show". Further US prosecution details are available via the USPTO Public PAIR system.
