That&#x27;s right. MIT does not protect you from any patent-related legal action. It&#x27;s not that hard to justify though - it&#x27;s the same for BSD and MIT&#x2F;BSD has been used for ages.<p>Both Apache and GPL grant patent use to everyone. I&#x27;d paste the relevant bit, but it&#x27;s stupid-law-level-long. Point 3 in <a href="https:&#x2F;&#x2F;www.apache.org&#x2F;licenses&#x2F;LICENSE-2.0.txt" rel="nofollow">https:&#x2F;&#x2F;www.apache.org&#x2F;licenses&#x2F;LICENSE-2.0.txt</a> - also see the exploding trap at the end of that point. You cannot sue the author for patent reasons.
