'patents trademarks etc' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'perfect for high-tech brand' is the wordplay.
'perfect' becomes 'hone' (synonyms).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'high tech brand' becomes 'ip' (I can't justify this - if you can you should give a lot more credence to this answer).
'hone' after 'ip' is 'IPHONE'.
