Could you go in to that a bit. There's been fulltext, full image databases with proximity searching and bespoke classifications and such for a while, how has Google Patents improved on that. How is it better than Espacenet for example?

When I looked at patents a lot the biggest help would probably have been being able to get decent translations of Korean/Japanese/Chinese/etc. patents - I gather you were involved in an EPO project to do that. What other goodies have I missed?

Worth noting is that this is fine in most jurisdictions as long as your not trying to commercialise the build.
