Let me go back to software. If I buy detection software, such as that from Norton, for example, I will own a license contract. Every month, I will receive an e-mail telling me to download the new anti-virus updates. If I understood correctly your presentation, after 18 months, this would become illegal, there would be a fine because the 18-month period would have expired.
