1.3 What is the difference between the types of KNX Membership?

There are 3 different types of KNX Membership: interested party, royalty per unit licensee and shareholder:
Interested Party: As an interested party you get access to the KNX know-how, marketing benefits and the tools. But you may not develop and certify KNX products and you have no vote in the decision making process. This membership runs on a yearly basis.
Royalty per Unit Licensee: You get access to the know-how, marketing benefits and tools and you get a Manufacturer’s ID and are allowed to develop KNX products and have them KNX certified. You have no vote in the decision making process. A license runs for 5 years and can be prolonged each time the license has expired.
Shareholder: As a shareholder you get the know-how, marketing benefits and tools, can develop KNX devices and get a vote in the KNX decision making process. This membership runs on a yearly basis.
