How do I get a patent for developing a proprietary product?

Yes we do - however there are some short statutory time frames for filing a patent in the US that must be adhered to. Basically 12 months from the time you filed for your patent overseas or had your first public disclosure, sale or offer to sell.

Prices range the gamut, and also depend whether you want a provisional patent application or regular utility patent application. Design patent applications are also a possibility. Please call a patent attorney before too long to avoid running into the so-called "bar date" in which you can actually lose rights to your invention by not filing in time.
