AFAIK it is typical to refer to the country where the speaker lives as this country. For example, if a person lives in Great Britain and he wants to mention weather in Great Britain, he might say "weather in this country is blahblahblah".
Now we have a text written by a citizen of Great Britain saying something like "Patent law is quite complicated in the USA. In this country blahblahblah..."
What will "this country" naturally refer to in the second sentence - to the USA or to Great Britain? How would the author change his text so that it is clear that the second sentence also refers specifically to the USA or to Great Britain?
