The sheer cost of the patent process means Death2Spam founders Richard and Mike Jowsey won't be rushing to protect their Bayesian spam filtering product.
Richard Jowsey has just been to Massachusetts Institute of Technology to speak at its annual Spam Conference and was well received, says brother Mike.
"[Conference organiser] Dr Paul Graham was impressed enough to be introducing Richard as 'Mr Bayesian'. He told Yahoo they need D2S technology today."
Mike Jowsey says the danger in such conferences is that you'll give your competitors too much information about how your product works and that can be a problem.
"The danger is that you might point your competitors in the right direction without meaning to, but at the end of the day we're all fighting spam and that's what's important."
D2S has been in talks with spam filtering giant Brightmail over its technology for some time.
"Because D2S takes such a different approach to the others they were really interested in what Richard had to say."
However the costs involved in taking out patent protection are so great, Mike Jowsey doesn't think D2S will be getting the intellectual property protection the company should have any time soon.
"It's not really viable without venture capital funding and our income is better spent on developing the product."
D2S's enterprise edition package is to go on sale in the US on March 1 and Mike Jowsey says he's been working closely with distributor Binary Research International to make sure the marketing and even the product itself is up to scratch.
"They've been making us jump through some serious hoops and we're happy to do that to make sure it's a success."
