While LEMO connectors were generally developed as proprietary designs, the legal status of many of the older designs is not clear. For example, the LEMO website shows a standardisation date of 1970 for the LEMO 00 model. The "chocolate plate" design of the connector's shell grip is, however, trademarked.<ref>USPTO registered trademark number 2703464, see LEMO FAQ: [http://www.lemo.com/en/faq/general#t9n3514 Are LEMO connector design trademark registered?]</ref>
