Is this sort of thing an issue in other countries. I'm a tech founder in Australia. I don't think we have the same level of anxiety about being sued for unknowingly breaching a software patent. Can anyone comment on this? Is our patent system different or can we expect to see our industry similarly affected in the future?
Patents are territorial. That is, unless someone has filed an application (or designated Australia as part of a national phase of a Patent Cooperation Treaty (PCT) patent application, nothing will issue in Australia. Generally, companies try to figure out where their likely markets are, and where the expense can be justified. Australia is becoming more and more relevant, but it was not nearly as common to file there a few years ago. (Full disclosure, I'm a U.S. patent attorney (but I'm actually a good guy!).)
That's a bit reassuring to me. I'm not anyone special, but I've got some ideas I want to code up that likely won't get anyones attention. After seeing patent topics popping up here on HN so often, I'm seriously terrified of even being a programmer anymore. This stuff makes me want to give up and find a job digging ditches or something, Office Space style.
But, I'm Canadian. Your comment makes me feel a bit safer, but I have the feeling that little things like hosting the site in the US or collecting money from Google AdSense or an Amazon Affiliates account could make me horribly liable.
I know that rationally this practically a non-issue, since I'm such a low value target, but the fear is still there, lurking beneath the surface, scaring the hell out of me.
