Much of the discussion about ownership of information has been a discussion
about terminology.  In my experience of this and other similar discussions,
trying to define what constitutes owning information by analogy with what
constitutes owning familiar physical objects (like pieces of paper) is not
a helpful project.  

The reason may well be that physical objects are relatively stable and
persistent, and therefore support an intelligible distinction between what
is the original owned object and what is a mere copy.  Information may
reside in well fixed physical objects, or in less well fixed electronic
ones; and in either case is easily transformed and transferred in ways that
destroy conventional ideas of what is a copy and what is an original.  If I
have an apple locked in my safe, you can't have the same apple locked in
your safe.  If I have some information secured somewhere, you may also have
the same information secured somewhere else.

I hope this suggests why discussions based on ownership of information can
be confusing and sometimes not very illuminating.

It is of course true that rights in information can be owned, as
intellectual property rights show.  The most relevant right in the context
of the earlier discussion is the right to have information kept
confidential - a client's right, for example, not to allow his lawyer to
release the content of legal advice given by the lawyer or the content of
the information the client gave the lawyer for the purpose of obtaining
that advice.  That can be understood without reference to the idea that the
client owns the information, which as a proposition seems to me to add
nothing useful; and it tends to lead to discussions about whose ink and
paper were involved, which I think is irrelevant.

In the medical context, I think there is no doubt that what the patient
tells the doctor is confidential.  The precise scope of the duty of
confidence owed by the doctor to the patient depends on what the patient
consents to, expressly or by implication.  No doubt there is some general
consent to access by other doctors in the same practice, and perhaps by
some practice staff (e.g. a practice nurse).  There may be specific
consents to disclosure to a specialist on referral.  The NHS likes to
think, I suspect, that there is some woolly general consent to any
disclosure within the health service for the good of the nation's health in
general:  I think that anything of the kind is most dubious.  I find it
surprising how vague all this is, and perhaps it's time to reward a few
lawyers for litigating it to a point if clarity (but I'm not volunteering).
