Adelaide, 11 February 2010: From small beginnings in 1968, Adelaide's Madderns Patent and Trade Mark Attorneys has now risen to be amongst the "Top Ten" of Australia's patent firms.

Respected international journal Managing Intellectual Property recently released the results of their 2010 global survey of intellectual property firms. The results of the survey are based on extensive research and interviews conducted by MIP with practitioners and clients internationally.

Receiving a very high MIP ranking in the category of patent filing and prosecution, Madderns joins a group of much larger and established patent firms in Australia's "Top Ten"; it is the only firm in the top two tiers which has its primary office outside of the traditional strongholds of Melbourne and Sydney.

Commenting on the survey results, Madderns Senior Partner Craig Vinall said "The MIP rankings reflect an outstanding effort by all partners and staff to the progression of the firm. It vindicates our belief that we are able to offer IP services that are up there with the very best on offer nationally".

The firm acts for a large number of South Australia's iconic companies including Clipsal, Yalumba and Hills Industries along with large Eastern States-based businesses such as Cochlear and Stockland, and international giants such as Qualcomm.
