In-text: (McMillan et al.)
Persistent URLs to patents may be difficult to locate; Google Patents is usually the best source for these. As with other electronic sources, omit the http:// or https:// from the citation (MLA 110). Because multiple individuals are involved in the filing of the patent, you should cite the contributor(s) that you wish to emphasize, followed by a descriptive label of their function (typically inventor) (MLA 37). You should also indicate that you are citing a patent by adding Patent after the date issued, or ideally U.S. Patent followed by the patent number (MLA 53; 105).
