I only know what happened in my case. I worked for a Swiss company that was bought by Adobe. They pretty quickly expanded our office and we became an rnd center - the other in Europe being Hamburg. Other examples, macromedia became their san francisco offices, navisware or some other purchase became an office in north carolina.... They must eventually close some down though - they've bought a ton of companies in the last 10 years.
