FAQ: How much do you charge for drafting and filing a patent application?

A ballpark figure is thousands of dollars for properly drafting and filing a patent application, depending on the complexity of the invention - your invention may be as simple as a simple improvement to a golf ball, for example, or it may be as complex as an entire combustion engine - and cost varies accordingly. To put patent cost in relation to patent value, 6000 Nortel patents were sold for $4.5B which amounts to $0.75M per patent on the average.

To get a cost estimate based on facts, you could either take the free Worksheet option or the fee-based consultation option. This is similar to bringing a car to a repair shop to determine what needs to be done and put in the Service Contract.
