AFAIK if you want international patent, you have to file a patent claim in every country and that costs lots of $$$,

According to a study commissioned by the European Patent Office on “ The cost of a sample European patent”, the total cost of obtaining a typical Euro-direct patent (validated in 6 countries, with 10 claims on 3 pages, 11 pages of description) was about €30,000 in 2003. In its July 2000 proposal for a Community patent, the European Commission also estimated the costs for obtaining a European patent in 8 countries at around €50,000, including estimated translation costs of €12,600, agent's fees of €17,000 and renewal fees of €16,970 (see Memo/00/41).

And that is only for Europe
