i wonder: if you don't have a contractual relationship preventing it, can't fb revoke your permission to use their patents at-will? if so, has removing the patent grant actually changed anything?
- teraflop 9y agoIt's actually the other way around, as I understand it. This is one area in which patent law and copyright law differ noticeably. Due to the way implied patent licenses work, if Facebook distributes React without explicit restrictions or conditions, they're automatically granting a license to any patents that are inherently infringed by React itself. This is a pretty well-established area of US patent law, see e.g. https://www.wilmerhale.com/pages/publicationsandnewsdetail.aspx?NewsPubId=95535 https://www.wilmerhale.com/pages/publicationsandnewsdetail.a...
- abiox 9y agoafaik no component of react is covered by a fb patent, so a fb patent revocation wouldn't impact one's use of react. if fb actually wanted to prevent someone from using react, they could just revoke the copyright grant.
- spicyj 9y agoThe LICENSE file is a grant that Facebook can't revoke even if it wanted to.
