Apologies if I've gone off at a tanget by completely misunderstanding the article.
No apology needed. It's more likely that it was me who misunderstood it.
That said, you wrote:
I thought it meant that the already protected intellectual property held by Uni was going to be made freely available to researchers and businesses. I was thinking along the lines of all the research notes that are currently in existence and being able to access these freely as an aid to further research and development of business models and ideas.
That's now how I read it. It's more a case of specific bits of IP, including patented technologies, being made available under llicence as at present, but the process will be simplified, and there will be no charge for the licence. The licensee will still have to enter into an agreement with the university, and the university will decide what IP it wants to license in this way.
Regarding your point about sending a sealed copy of your published work to your solicitor under recorded delivery, etc. I expect you know that this is really not necessary. You already own the copyright in any work that you create, regardless of the above precautions. However, the actions you describe could be useful if you need to defend your copyright in the courts, but it certainly doesn't give you additional rights.
Regarding depositing copies at the British Library, etc. You're right that this is a legal requirement - for books, pamphlets, newspapers, etc. - but it has got nothing to do with copyright. Making such a deposit does nothing to increase your copyright protection, and failing to do so doesn't detract from the protection. In particular, it only applies to certain forms of
published work.
I admit this is a confusing area. That's partly because the six libraries to which you are required to make the deposit are sometimes referred to as "copyright libraries". That's probably because they were originally set up by the Copyright Act of 1911. But the present legal requirements for depositing books at the libraries are separate from copyright legislation.
By the way, A. P. Herbert wrote an interesting and amusing exposé of the "copyright libraries" in
Wigs At Work - an enlightening book, but not to be taken too seriously.
