Patentability Opinions

A patentability opinion advises you as to whether or not it may be worth the time and expense of pursuing patent protection. These opinions answer the questions of what possible action the patent office might take on your application and whether or not it is likely that the patent office will grant a patent for the invention claimed in your application.

Such opinions are not a guarantee that a patent will or will not be granted. Rather, they are our assessment of the likelihood of obtaining patent protection, based on our experience in these matters.

Patentability opinions cost an average of $1500 if delivered in writing and as low as $800 if delivered verbally. The costs can increase to several thousand dollars depending on the complexity of the invention and the number of prior art documents found.
