From the patent: 'The rules could also specify that the available media be constrained by a rating, such as a parental rating (e.g. G, PG, PG-13, R, etc.) or media that excludes explicit lyrics or language. In other examples, the gift instrument purchaser directs that the gift instrument can only be redeemed for books (e.g., not video games), books of a selected genre (e.g., romance, action, historical, etc.), books having a selected author, etc.'
