As of February 2008, there is some discussion as to the status of the above-mentioned patents. While the USPTO still shows them as active patents, a number of other radio manufacturers have begun including MDC-1200 support in their products. Vertex Standard manufactures OEM add-on boards for their mobile and portable Land Mobile Radios that support MDC-1200 ANI (or PTT ID). Icom Incorporated includes built-in MDC-1200 features on some of their newer radios including the IC-F3021/4021 portables and IC-F1721/1821 mobiles, as does Kenwood Electronics.
