Question juridique clé
Whether the 2009 patent-related payments were AHV-pensionable self-employment income or exempt capital return.
Solution extraite
The payments were income from gainful activity and therefore subject to AHV/IV/EO contributions.
Motifs extraits
Because the deceased was an inventor whose activity generated the patent-related earnings, the amounts had a relevant causal link to his professional activity. For professional inventors, royalties from exploitation of inventions are contribution-bearing without needing proof of continued personal participation in exploitation.
