Much data is available about US patent cases and their costs (See my post of Oct. 2, 2008: costs of patent litigation, with 13 references.). Nothing has appeared on this blog, however, about costs north of the border.
Now I can venture up there: “Canadian litigators estimate that it takes about C$500,000 of a client’s money to bring a case to trial, and another million or two to see it through to end-game.” This quote, from Lexpert (Guide to Leading Cross-Border Litigation Lawyers), Nov. 2009 at 24, suggests that Canadian costs through trial are a million US dollars or so less than south of the border.
