I have [          ] an umbrella that works well when it is windy. I have applied for the patent and I have been assured that there is a company that will make the product.

I have invented something that I [          ] the other night and I want to know what you think about it.

Thank you for inventing this but until we know that it is patented we have not [          ] any at all for the market.

I don't think that this has been newly [          ] at all. I can see that it has already been patented. Did you know this before you showed it to me?

I think this is the most wonderful invention I have ever seen. Have you [          ] it yet?
