8.13 Search Activity – Using the IPC Green Inventory to find a patent for processing waste tyres and using patent family data to determine freedom to operate

Your client, Molectra Technologies, based in Australia, has written to you about the tremendous challenge of responsibly disposing of the 1000 million old tyres the world throws away every year. Landfills are banned in many countries and are no longer a viable option. The durability of tyres and their resistance to puncture, slicing, and decomposition at moderate temperatures makes disposal difficult.John Adams, the Managing Director of Molectra, believes that the best solution is pyrolysis ie thermal decomposition in the absence of oxygen, and he is aware of a European patent entitled “METHOD AND DEVICE FOR THERMALLY TREATING USED TIRES”, which describes a similar technique involving pyrolysis of comminuted tyres. Use the IPC Green Inventory as a starting point to find this patent; and use patent family data to see whether there is an Australian patent that would stop Mr Adams from using this invention.
