I frequently come across this expression in technical writing:
This document is copyright (c) 2012 XYZ Company Inc.
Is that a correct/acceptable way to express it? "This document is copyright..." sounds very weird to me.
Do the copyright laws of the UK or US perhaps mandate or necessitate a wording such as this?
EDIT
It has been suggested to close this question because it is a legal question, not a usage question. So I feel I need to clarify:
This is meant to be a question about English usage. The core of my question is the words, "Is that a correct/acceptable way to express it?", by which I mean "correct and acceptable English usage." My last sentence is merely meant as a possible guess as to the reason for a possibly strange usage.
