USA is negotiating new free trade agreements with Europe as we speak. If they win, the sw patents might be soon enforceable in EU. S3TC will expire in 2019 anyways. See http://www.google.com/patents/US5956431

Doesn't it expire Oct 2 2017?

I don't think so. If you look at the fee payment history, 2003 is year 4, 2007 is 8, 2011 is 12. The patents are valid for 20 years. So 20 comes in 2019. I could be wrong. Maybe the law has changed.

You might be right. The formula changed in 1995 or so if I understood it correctly.
