Jerry Hoslin, Director & Founder, WearX

I have been involved in business consultancy for over 25 years. This has involved launching new businesses, ideas, products as well as assisting existing businesses to expand. In that time I have experienced many start ups and dealt with a large range of Intellectual Property. Andrew Caska, Principal Patent Attorney of Caska IP, has recently provided his services to one of my clients and we worked closely to formalise important patents and trade marks. His understanding of the invention, his work and timely delivery were all first class and we are very happy with the outcomes.

Grant Harms, Business Consultant,

Caska IP has been more than supportive in protecting Automed Pty Ltd IP for the agricultural and medical industry. In working with IP& we have developed a clear IP strategy for patents and trademarks for our products, for the Australian market and the international market. We are more than happy with their dedication and level of service and would recommend them to any small or large organisation

David Edwards, CEO & Founder, Automed Pty Ltd

As an individual inventor, I set out to find a Patent Attorney service that was accessible and reasonably priced to assist in lodging my first patent application. I found Caska IP to be not only affordable and accessible, but highly professional and attentive to my needs and requirements. Caska IP worked with me to assist in refining my idea and expressing its unique qualities. I highly recommend Caska IP to the individual inventor.

Lester Walters, Inventor, QUAD R&D Pty Ltd

I was relatively unaware of what was needed and admit to being a bit nervous. Your perception and interpretation of what I was trying to achieve gave me great comfort. On receipt of the initial draft I was impressed with the professional presentation and the attention to detail with little alteration being required. You may rest assured that I will be using Caska IP for future projects (of which I have several) after this one is put to bed.
