To be pedantic, although most intangible assets can be capitalised, IFRS does not allow capitalisation of internally generated brands. If you buy a company then you can capitalise any brands you obtain on acquisition.
Development expenditure on patents can be capitalised only in certain circumstances.
The part about brands and patents being treated as an expense is wrong though
Even stuff like website development cost can be capitalized as an asset under some circumstances
