BRUSSELS (Reuters) - EU antitrust regulators are set to open a full-scale investigation into French aerospace and defense group Thales' TCFP.PA 4.8-billion-euro ($5.6 billion) bid for Franco-Dutch chipmaker Gemalto GTO.AS, two people familiar with the matter said on Thursday.

The move by the European Commission comes after Thales declined to offer concessions to address concerns about overlaps with Gemalto, the people said. The deadline to do so was July 16.
