Orchestrating two more trans-Atlantic collaboration agreements, Massachusetts Governor Deval Patrick signed memorandums of understanding Wednesday to work on life sciences, renewable energy, and information technology research with Catalonia, Spain, and the Medicon Valley in Denmark and Sweden.

The agreements were signed at the Biotechnology Industry Organization’s ­annual convention in Boston, where Massachusetts officials unveiled a string of deals and investments this week.

“Catalonia and Medicon Valley are important regions in Europe’s innovation sector, and these partnerships will allow us to move forward on our mutual goals in this part of the global economy,” Patrick said in a statement.
