Dish and item of furniture that may be put on list of inventions (10)

I believe the answer is:

patentable

'that may be put on list of inventions' is the definition.

'dish and item of furniture' is the subsidiary indication.
'dish' becomes 'pate' (I've seen this in other clues).
'and' becomes 'n' (common abbreviation for 'and').
'item of furniture' becomes 'table' (I've seen this before).
'pate'+'n'+'table'='patentable'

I've seen this clue in The Guardian.
