No damages for unjustified threats

Following on from the Full Court’s warnings in Australian Mud Company v Coretell, Dowsett J has now dismissed Morellini’s claim for damages for unjustified threats. This is a short point, but it bears notice as people often come to me thinking it is enough to show there has been an unjustified threat – it isn’t, if you want monetary compensation.

Mizzi and Morellini are both in North Queensland and came up with machines for planting sugar cane. Mizzi patented his. Dowsett J found that Morellini’s machine did not infringe Mizzi’s patent and Mizzi had made unjustified threats of patent infringement. On appeal, the Full Court also ruled that Mizzi’s patent was invalid for false suggestion.

There was no dispute that Mizzi had made unjustified threats. On 5 April 2010, it had caused to be published in the Canegrower trade magazine a notice about its pending patent and an article by “Invention Pathways” about the consequences “[i]f the patent owner decides to pursue his rights ….” Then in June 2011, Mr Mizzi made oral threats to a Mr Girgenti about the use of a Morellini machine.

The problems for Morellini were essentially two fold. First, much of the evidence about people’s reluctance to deal with Morellini related to things which happened before the threats were made or in circumstances where Dowsett J could not attribute them to the actual threats as opposed to just rumours circulating in the industry:

There is no direct evidence that anybody declined to deal with Mr Morellini as a result of the threats. It seems that even before the newspaper article on 5 April 2010, there was a degree of reluctance concerning any such dealings. That reluctance cannot have been attributable to the threats. Mr Morellini has not demonstrated that any adverse effect resulted from either of the threats.

Secondly, Dowsett J accepted that damages could be available for lost sales opportunities and delayed sales, if they could be linked to the threats. However, Morellini did not provide detailed evidence about how he would have exploited his machine commercially and why he had not been exploiting it “in more recent times”. That is, Dowsett J wanted to know what was Morellini’s plan (if he had one) for exploiting his machine commercially and why he had not been doing so.
