Some reflections on the duality of regime for software protection in the European Union

Although the framework for protection of computer programs has been established in the European Union more than two decades ago, it has not undergone any major changes. Opinions of Advocate General Yves Bot have convinced the Court to advance the concept of the plurality of copyright regimes applicable to software: source code, object code and documentation would be protected under the Software Directive, whereas interfaces, programming languages, data formats and software manuals are dealt with as literary works under the InfoSoc Directive. In SAS Institute v WPL, the Court also ruled that copyright in a computer program cannot be infringed where the lawful acquirer of the license neither decompiled the object code nor copied the source code of the computer program, but merely studied, observed and tested that program in order to reproduce its functionality in a second program. This ruling paves the way and acknowledges the reverse engineering efforts on the Old Continent.
