Yeah, looks like we might need a new one. The closest I could find were:

• Saint Thomas More (http://www.vatican.va/holy_father/john_paul_ii/motu_proprio/documents/hf_jp-ii_motu-proprio_20001031_thomas-more_en.html): Patron of Statesmen & Politicians
• Gabriel the Archangel (http://www.catholic-forum.com/saintS/saintg03.htm): Patron of Communication.

BTW, this site (http://www.catholic-forum.com/saintS/patron00.htm) indexes many of the saints' patronages, maybe you can find a good one. =)
