Robert,
I'm not certain that I understand your comment. However, I can assure you that any patent protection for the device in question will not delay the product's release in any way.
In theory, many different designs are possible, although for one company to market a number of competing designs is impractical.
Every effort is being made to bring an effective and complete device to market as soon as possible. I can assure you of that.
