Basic level bedside computer-assisted diagnostic aids are largely search engine and tag-cloud based, so most of the basic info is already in the public domain, and can be accessed via portals such as PubMed. As I understand it, the article refers only to one psychological test and, later, another tool, both of which were withdrawn by the (US based) authors.
While not wishing to offend anyone, I put it down to the notoriously rampant zeal for litigation in said country, and dismiss it as a storm in a teacup, until proved otherwise.
The article mentions the MMSE only as an example of an established diagnostic tool, utilized worldwide by clinicians, who now find themselves forced to pay an ad hoc fee each time the test is performed or become liable to penalties for copyright infringement.
The MMSE is by no means unique. See http://www.mdcalc.com/framingham-cardiac-risk-score# for a short list of diagnostic tools to which similar copyrights could be applied.
For an example of the "copyleft" mentioned in the article, see the new UK Prospective Diabetes Study calculator for coronary artery risk "conditions of use and copyright" statement: http://www.dtu.ox.ac.uk/riskengine/download.php
