It seems that at some time in the 19th century, the US patent office decided not to allow the patenting of alternatives indicated by the word «or», so that one could not say, for example, «fluorine, chlorine, bromine or iodine».

... This brings up the nightmarish thought that if the chemical industry had developed organobromine compounds instead of the CFCs — or alternatively, if chlorine chemistry would have run more like that of bromine — then without any preparedness, we would have been faced with a catastrophic ozone hole everywhere and at all seasons during the 1970s, probably before the atmospheric chemists had developed the necessary knowledge to identify the problem and the appropriate techniques for the necessary critical measurements.
Over the long term, the size of the ozone hole is governed by emissions of chlorine and bromine containing compounds, for example chlorofluorocarbons (CFCs), generated mostly by human activities.
