I will evaluate your invention on a case by case basis and provide an
estimate for the cost to prepare and file a patent application.
Additionally, further fees would be due a year or so after filing for my
time to respond to patent office opinions, etc. The patent office will send
a letter (called an "office action") that addresses the patentability of
your invention. My job is to persuade them (if I disagree) and/or advise you
as to the best course of action.
The patent office charges various fees associated with patent applications
and issued patents. For instance, there is a filing fee due when the
application is filed. Also, upon the issuance of a patent, there is an issue
fee due as well as maintenance fees that must be paid at the 4, 8, and 12
year marks.
