Five applications have been lodged in Australia with one innovation patent granted and now in the examination phase.
Another two patent applications have been lodged in Malaysia as part of the company’s commitment to place itself in a strong position to protect its intellectual property rights.
The patent applications have been lodged in the name of Altech’s wholly-owned subsidiary, Altech Chemicals Australia Pty Ltd.
Altech aims to become one of the world’s leading suppliers of 99.99% (4N) high purity alumina.
High-value, high margin product
HPA is a high-value, high margin and highly demanded product as it is the critical ingredient required in the production of synthetic sapphire.
This product is used in the manufacture of substrates for LED lights, semiconductor wafers used in the electronics industry, and scratch-resistant sapphire glass used for wristwatch faces, optical windows and smartphone components.
Scratch-resistant synthetic sapphire glass.
There is no substitute for HPA in the manufacture of synthetic sapphire and the product is also increasingly in demand as a key component of separators in new age batteries.
Granted Innovation Patent 2018101228 covers the production of alumina from all types of aluminous clay, including kaolin, using hydrochloric acid.
The prescribed process for an Innovation Patent following grant, is that the patent is examined by IP Australia and once this is passed, the patent is certified then published.
Granted patent in examination phase
IP Australia recently issued its initial examination report for this patent and has queried the innovation and novelty of the Altech HPA Process.
Altech now has six months to respond to IP Australia and remove grounds for revocation of the patent, else the Innovation Patent will cease.
The company, via its Patent Attorney WRAYS, will now respond to IP Australia with further clarification and justification as to the innovation and novelty of the process.
Re-use of HCI gas
It is the view of the company and WRAYS that a significant and innovative step of the Altech HPA Process described in the Innovation Patent is the recycling and re-use of HCl gas, which previous patents did not deploy.
WRAYS has advised that a response to clarify patent innovation and novelty following an initial Innovation Patent examination is not unusual.
Growing demand for HPA
Global HPA demand was around 25,300 tonnes in 2016 and demand is growing at a compound annual growth rate (CAGR) of 16.7%, primarily driven by the growth in worldwide adoption of LEDs.
As an energy efficient, longer lasting and lower operating cost form of lighting, LED lighting is replacing traditional incandescent bulbs.
HPA is a key compopnent of LED lights.
Current HPA producers use expensive and highly processed feedstock materials such as aluminium metal to produce HPA.

Altech has completed a Final Investment Decision Study (FIDS) for the construction and operation of a 4,500 tonnes per annum HPA plant at the Tanjung Langsat Industrial Complex, Johor, Malaysia.
The plant will produce HPA directly from kaolin clay, which will be sourced from the company’s 100%-owned kaolin deposit at Meckering in Western Australia.
Altech’s mezzanine debt and stream facility technical due diligence is on track and proceeding as planned for its proposed Malaysian high purity alumina (HPA) plant.

HPA plant construction will run in parallel to finance close, as stage I construction is already funded and will begin shortly.
