What does the patent grant for Golang mean? Can I use Golan for whatever I want (like the BSD license implies) or does it limit my use of Golang in any way?
Here is the text of the patent: https://golang.org/PATENTS?m=text
In the license for the GO software Google grants a licenses to the patents that Google owns regarding the GO software.
here such license applies only to those patent claims, both currently owned or controlled by Google and acquired in the future, licensable by Google that are necessarily infringed by this implementation of Go.
Go is an open-source programming language that makes it easy to build simple, reliable, and efficient software. And Golang is Go Language. If someone builds software using Golang and registers it as Patent, then it is said as Golang Patent.
