Business property rights may refer to those things that a business entity or business owner should be able to control, legally, morally or otherwise, whether it be in the physical world, the virtual world, or the combination of both. One example of this is a business owner who wants to control (and potentially monetize) their place of business by promoting their own products/services or wants to lease their space to a third party (relevant, complementary, highest bidder, other) so they can monetize by property. Another possibility is a business owner who wants to control who can promote/advertise to enforce things important to them (brand, family values, non-competitive, etc.).
A building owner may also want to lease out their property for xR uses. They may be willing to allow their tenant to advertise on their property (similar to virtual billboard) when someone is in their place of business (and only for their place of business). For example, an individual owns an ice cream shop and has considerable foot traffic (and eyeballs) waiting for ice cream. As such, they would like to lease their xR property to advertisers that would be willing to access their foot traffic and customers (such as complementary stores in the same business complex).
The property owner may also want to control (or delegate) monetization their property (or otherwise transact for something in exchange). They may also have multiple tenants or businesses on their property, and each should be controlled and tracked separately.
