Hydrodec Group plc announced that The European Patent Office granted a European Patent which strengthens Hydrodec's Intellectual Property position in the global market and will lead to validation in the UK, German and Danish markets. This milestone adds to the recent US Patent grant. The Patent protects the operating and design intellectual property improvements made to its original re-refining technology developed over ten years of commercial operation. The grant of the European Patent reinforces the ongoing commercial protection of Hydrodec's proprietary technology leadership in the production of sustainable and high quality oil products at market competitive prices. Hydrodec licenced the original Patent for the production of electrical insulating oil from used oil from CSIRO, Australia in 2004, with the full rights assigned in 2009. The European Patent captures design and process improvements to the re-refining process that enhance process economy, reliability and consistency of the core re-refining technology.
