US government copyright policy

If all the Named Authors are employees of the US Government:

• they, and the authorised signatory of the US Government (“US Government Signatory”) represent and warrant to IOP and its licensors that the submitted article (the “Article”) was prepared as part of their official duties. In such circumstances, none of the original content within the Article is subject to copyright protection within the USA as it is in the public domain within the USA.  However, in signing the copyright form, the US Government Signatory grants IOP and its licensors a non-exclusive royalty-free worldwide freely-transferrable perpetual licence for the full term of copyright (including any extensions or renewals) for all media and formats, whether known or unknown, to do in relation to the Article (which expression includes but is not limited to the text, abstract, tables, figures and graphs, related corrigenda or “comments” and multimedia content but excludes any other item referred to as supplementary material and/or any video abstract) all acts restricted by copyright worldwide including the right of action, to the extent that such rights exist outside of the USA.

If one or more of the Named Authors are employees of the US Government (“US Government Authors”) and one or more of them are not employees of the US Government:

• the US Government Authors and the US Government Signatory represent and warrant to IOP and its licensors that their contributions to the Article were prepared as part of their official duties. In such circumstances, none of the original content in the US Government Authors’ contribution is subject to copyright protection within the USA as it is in the public domain. However, the original content in the other remaining Named Authors’ contributions is subject to copyright protection. In signing the copyright form, the US Government Signatory grants IOP and its licensors a non-exclusive royalty-free worldwide freely-transferrable perpetual licence for the full term of copyright (including any extensions or renewals) for all media and formats, whether known or unknown, to do in relation to the Article (which expression includes but is not limited to the text, abstract, tables, figures and graphs, related corrigenda or “comments” and multimedia content but excludes any other item referred to as supplementary material and/or any video abstract) all acts restricted by copyright worldwide including the right of action, to the extent that such rights exist outside of the USA; and
• one of the Named Authors who is not a US Government Author grants IOP and its licensors a non-exclusive royalty-free worldwide freely-transferrable perpetual licence for the full term of copyright (including any extensions or renewals) for all media and formats, whether known or unknown, to do in relation to the Article (which expression includes but is not limited to the text, abstract, tables, figures and graphs, related corrigenda or “comments” and multimedia content but excludes any other item referred to as supplementary material and/or any video abstract) all acts restricted by copyright worldwide including the right of action, to the extent that such rights exist outside of the USA.

In addition, the US Government Signatory on behalf of the US Government grants IOP and its licensors a royalty-free non-exclusive freely transferrable licence for the full term of copyright (including any extensions or renewals thereof) to the extent that such rights exist outside of the USA to do in relation to any supplementary material not deemed to be part of the Article and/or any video abstract all acts restricted by copyright worldwide.  This shall include, but not be limited to, making the material available under any licence that IOP and its licensors deem appropriate for purposes including the maximisation of visibility and the long term preservation of the content.
