EE 18B: Cost: some depreciable intangible property

You could also call this:

"What you paid for things that lose value over time, like patents and designs"

When you buy something that can lose value over time, like a patent or a design, you need to know its cost. The cost includes money you spent on things that help create or support it, if you spent that money on or after 7 November 2013. This rule applies to things like patents, plant variety rights, and design registrations, as mentioned in section EE 16. You must have spent the money on or after 7 November 2013 for some types of items. These items are things like patents and design registrations. You cannot claim the money you spent as a deduction under other rules. The cost of some intangible property, like industrial artistic copyright, is also included. You need to know what you can and cannot claim as a deduction. This helps you work out the cost of the item, as required by the rules in section EE 16.
