Further, we have summarized the most relevant ICT-standards and medical-managerial Guidelines involved, enabling interoperability in contemporary home-care and assisted-living. Finally, we have created various home-care related “patent-maps”, by employing the European Patent Office (EPO) search-engine esp@cenet and other sources. By combining these three steps, we have attempted to use the early disclosing potential of published IP-documents, to reduce eventually intentional obscuring of IP-portfolios, as it will be presented in details, in the following sections. If some patented technology is “essential” for the implementation of a standard, then the corresponding patent granted is called Standard Essential Patent (SEP).
