I’ve been reviewing the contributions documentation for Google new language, and was curious about the idea of contributing a new package. It states that this should be included at the top of contributed source code:

// Copyright 2009 The Go Authors. All rights reserved.
// Use of this source code is governed by a BSD-style
// license that can be found in the LICENSE file.

My understanding of a BSD-style license is that it essentially means that the user needs to attribute the code to you, but can do whatever else they want.

Further down it says:

If you are the copyright holder, you will need to agree to the individual contributor license agreement…

In the “individual contributor license agreement”, it says that Google has patentable rights to the contributed code:

You hereby grant to Google and to recipients of software distributed by Google a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work, where such license applies only to those patent claims licensable by You that are necessarily infringed by Your Contribution(s) alone or by combination of Your Contribution(s) with the Work to which such Contribution(s) was submitted.

To what extent does Google own any Go contributions? Do they have full rights to profit from these contributions?

    To what extent does Google own any Go contributions?

    You are not required to transfer copyright to Google. You still OWN the copyright.

    You are not required to transfer ownership of patents to Google. You still OWN the patents.

    In short Google does not OWN any IP that they didn’t already own.

    But you do grant Google the unlimited right to use and distribute your contributions, and you grant the right to use to downstream folks. Clause 2 covers copyrights, and clause 3 covers patent rights. Moreover you grant this as an irrevocable license (i.e. you cannot change your mind) and for free.

    Do they have full rights to profit
    from these contributions?

    There is no such a thing as “a right to profit” in a legal or moral sense. Hence “full rights to profit” is not a valid characterization of the rights that you currently have.

    By granting Google non-exclusive, non-revocable copyright and patent licenses, your remaining rights are no longer exclusive. Google will be able to profit your contributions, but so will you. You will have reduced your scope for personal profit, but that was not ever a “right”.
