I have got a paper accepted in a conference, they have told me add a copyright notice code at the bottom of page 1. This is my first time in conference and I am confused whether the code is same for every paper based on the government/country or unique for every paper.
Eg. For papers in which all authors are employed by the US government, the copyright notice is:
U.S. Government work not protected by U.S. copyright
For papers in which all authors are employed by a Crown government (UK, Canada, and Australia), the copyright notice is: 979-X-XXXX-XXXX-X/23/$31.00 ©2023 Crown
For papers in which all authors are employed by the European Union, the copyright notice is: 979-X-XXXX-XXXX-X/23/$31.00©2023 European Union
For all other papers the copyright notice is (Majority of papers will fall in this category): 979-X-XXXX-XXXX-X/23/$31.00 ©2023 IEEE As shown below on 1st page of paper.
