Apple (AAPL) and HTC have put an end to their patent fight, signing a 10-year cross-licensing deal that addresses existing and future patents, and which includes the dismissal of all litigation. Terms are confidential, and it's not clear if certain types of patents are left out. Apple recently demanded very high royalties from Samsung for just a small number of patents. Did it have a change of heart, or was HTC desperate to settle at any cost? Either way, Samsung and others might now face more pressure to cut a deal.
