Maybe for USM. For IS, however, there are several patents holders. The optics seems to me mostly Asahi patents. The only thing Canon seem to be the servo system. For any IS lens, there seems to lots of cross licensing. By reading the patents, it is certain that not one company control IS technology. I agree, however, that there are no signals that Pentax will release IS or USM anytimew soon, or at all. All they've done is to file patents on a modified K-mount that can use both USM and IS. P�l
