Editing MIT License (section)

== Relation to patents ==
Like the BSD license, the MIT license does not include an express patent license although some commentators<ref>{{cite web | url=https://opensource.com/article/18/3/patent-grant-mit-license| archive-url=https://web.archive.org/web/20210123091649/https://opensource.com/article/18/3/patent-grant-mit-license | archive-date=2021-01-23 | date=2021-01-23 | access-date=2021-01-23 | title=Why so little love for the patent grant in the MIT License?}}</ref><ref>{{cite web | url=http://oss-watch.ac.uk/resources/fossandpatents| archive-url=https://web.archive.org/web/20200503103939/http://oss-watch.ac.uk/resources/fossandpatents | archive-date=2020-05-03 | date=2020-05-03 | access-date=2020-05-03 | title=Free and open source software and your patents}}</ref> state that the grant of rights covers all potential restrictions including patents. Both the BSD and the MIT licenses were drafted before the patentability of software was generally recognized under US law.<ref>Stern and Allen, Open Source Licensing, p. 495 in Understanding the Intellectual Property License 2013 (Practicing Law Institute 2013)</ref> The [[Apache License]] version 2.0<ref name="gnu-license-list-expat"/> is a similarly permissive license that includes an explicit contributor's patent license.
Of specific relevance to US jurisdictions, the MIT license uses the terms "sell" and "use" that are also used in defining the rights of a patent holder in [[Title 35 of the United States Code]] section 154. This has been construed by some commentators<ref>{{cite web | url=https://writing.kemitchell.com/2016/09/21/MIT-License-Line-by-Line.html| archive-url=https://web.archive.org/web/20200503110018/https://writing.kemitchell.com/2016/09/21/MIT-License-Line-by-Line.html | archive-date=2020-05-03 | date=2020-05-03 | access-date=2020-05-03 | title=The MIT License, Line by Line}}</ref><ref>
