Résumé
A study or analysis of securities in connection with various types of immaterial property - such as debts, patents, trademarks or software - is a perilous exercise. It must take into account a wide range of regulatory instruments addressing the various ways in which the rules are implemented with respect to both the constitution and the realization of security. This opens up several different prospects, such as consolidation into a single form of security, the harmonization of rules, or the creation of a primary scheme that can then be extended using special rules.
