27In that regard, it should be noted that the criterion of originality cannot be met by the components of a subject matter which are differentiated only by their technical function. It follows in particular from Article 2 of the WIPO Copyright Treaty that copyright protection does not extend to ideas. Protecting ideas by copyright would amount to making it possible to monopolise ideas, to the detriment, in particular, of technical progress and industrial development (see, to that effect, judgment of 2 May 2012, SAS Institute, C‑406/10, EU:C:2012:259, paragraphs 33 and 40). Where the expression of those components is dictated by their technical function, the different methods of implementing an idea are so limited that the idea and the expression become indissociable (see, to that effect, judgment of 22 December 2010, Bezpečnostní softwarová asociace, C‑393/09, EU:C:2010:816, paragraphs 48 and 49).
