T 1621/16 - Multiple selections from lists of converging alternatives

In the present case, amendments were based on multiple selections from lists of converging alternatives (i.e. lists of options ranked from the least to the most preferred, wherein each of the more preferred alternatives is fully encompassed by all the less preferred and broader options in the list). The appellant (patentee) argued that these should not be considered to be equivalent to selections from lists of non-converging elements, and that these rather represented a restriction of the scope of protection and were allowable under Article 123(2) EPC. The opponent and the opposition division argued that amendments based on the selection of at least two intermediate options (i.e. different from the most preferred) from lists of converging alternatives infringed Article 123(2) EPC, and that lists of converging and non-converging alternatives had to be treated in a similar way, because the convergence could only be considered to provide a specific pointer to the most preferred options. The Board had to settle on the matter.
