Apple is looking for monetary damages and an injunction that will block HTC from selling phones using the infringing patents in the United States.
The complaints have been filed with the ITC, which can order HTC to halt sales, but complaints of this nature normally take months at the least and sometimes as long as decades.
HTC responded: "HTC values patent rights and their enforcement but is also committed to defending its own technology innovations," adding it did not have enough time to review all the claims.
