Can anyone explain the difference (if there is one) between an apparatus and a device when drafting a new patent application.
Are these two terms interchangable or do they actually mean different things?
For the claim it doesn't matter, because you're defining what the "apparatus", "device", "<insert any word>" is by what it comprises.
And if I find all the things that "<insert any word>" comprises, I've found an "<insert any word>".
If you claim:
A flying trapeze comprising:
an outboard motor.
And I find a boat comprising an outboard motor, I've found your claimed flying trapeze.
