From Patent Progress:

When the ITC excludes products based on patents that the USPTO says shouldn’t have issued, it can significantly—and negatively—impact the U.S. economy.  In this case, ordering exclusion based on an invalid patent would give Qualcomm the ability to cause significant financial harm to Apple and potentially force Intel (Qualcomm’s sole major competitor) to exit the baseband processor business entirely.  This, in turn, would raise prices for consumers, delay new advances in cellular technology, and potentially create threats to cybersecurity and national security.
