Patanjali lived in 200 B.C. Patanjali didn't mention any 'OM' chanting.
In fact, Patanjali doesn't seem to mention anything about any mantras or bija mantras at all in the Yoga Sutras. Apparently, the 'OM' chanting came after Patanjali, as did the composition of most of the tantras. So, 'OM' as a symbol came during the Gupta era, during the age of the alchemists and the siddhas.
