"To include the following but not limited to" is nothing more than a legal term as a catch all. If Handal names 10 products but forgot 3 others, or a new product hits the street that infringes at a future date, they can add them later.

In construction, buyers use this term on purchase orders as boiler plate. It is up to the seller to take exception to this statement.

Just legal mumbo jumbo and Fred won't offer comment to expose Handal's strategy, but if he does I'll be shocked.
