What are the EPC.App / PCT.App?

EPC.App is an annotated European Patent Convention (EPC) and PCT.App an annotated Patent Cooperation Treaty (PCT), which allow each user to further annotate them electronically and to receive updates from the authors without losing individual user annotations.

EPC.App /PCT.App are electronic books implemented as a web browser application, which offer for registered users:

  • to access and navigate the annotated legal text from anywhere via an internet connection (preferably on a display of 10" or larger)
  • to adapt authors' annotations to personal preferencesarrow_drop_down
    • remove individual authors' markings
    • change marking styles and colors
    • hide individual authors' comments and legal contents
  • to add own annotations, which get stored in the cloudarrow_drop_down
    • markings of the legal text
    • comments as separate text blocks (with links to other parts)
    • further elements selectable from a comprehensive database of relevant legal contents
  • to receive automatic updates of legal texts and authors' comments (each year in April and November)
  • to create a printable PDF-file as offline version or backup, which includes all self-edited annotations and closely reproduces the layout from the web browser application
