Most business property can be licensed, including intellectual property. The most common types of licensed property include:
Trademarks: A trademark license protects your trademark and how and where it can be used.
Digital assets: This includes things like software and apps.
Copyrights: This protects original work including artwork.
Patent license: This protects what many would call an invention.
Trade secrets are considered intellectual property, but they generally cannot be licensed. You normally have to use non-disclosures to protect them.
