Hi guys,
Thanks so much for your valuable answers.
I like your idea iab to ask for the financials in the contract. I don’t know if they would show me the financials but I like the legally binding right to view their financials.
And from all your replies, it would be for the benefit of the company to deal straight with a designer especially if the product sells well.
As for the clerk, I understand and even I sometimes don’t have time for my own ideas 
. However I still believe that once an application for a patent is submitted to the clerk, the clerk would sign a paper that the designer can keep in the file, acknowledging that the material submitted is confidential and provides the criminal penalties of doing otherwise. At least from a psychological point of view the clerk would each time be reminded how valuable the information he is handed and that it should be handled with utmost care.
Thanks again for the valuable information.
