What exactly does having a patent do for me?
Quoting the United States Patent and Trademark Office, "A patent is a type of property right. It gives the patent holder the right, for a limited time, to exclude others from making, using, offering to sell, selling, or importing into the United States the subject matter that is within the scope of protection granted by the patent."

How long is a patent good for?
A patent is granted for a term of 20 years. This term begins on the issue date and generally ends 20 years from the date on which the original U.S. application was filed.

How long does it take to get a patent?
The average successful patent application takes about 2-3 years from initial filing to issue. A simple application that proceeds without any claim rejections or other complications may take much less time, and a complex application may take much longer.

What are the basic Patent Office fees involved in obtaining a patent?
There is a filing fee, an issue fee, and three maintenance fees over the life of the patent. The amounts shown in parentheses are the reduced fees for small entities, which an individual inventor will usually qualify for. The fee information shown here is current as of April, 2004.
The filing fee is currently $770 ($385).
The issue fee is currently $1,330 ($665).
The maintenance fees due at 3.5, 7.5, and 11.5 years are $910 ($455), $2,090 ($1,045) and $3,220 ($1,610).

In addition to these basic fees, there may be other Patent Office fees involved in defending the patent claims against rejection by the patent examiner during the prosecution phase. There is also the amount charged at each phase by the patent agent or attorney for their work. This will vary depending on the complexity of the invention, the body of prior art to be researched, and what sort of rejections (if any) are offered by the patent examiner.

What's the difference between a utility patent and a design patent?
A utility patent covers the way something works; a design patent protects the exterior appearance of an article of manufacture and can overlap copyright and trademark protection. All design patents have "D" before the number. Like utility patents, design patents must be novel and unobvious. Design patents last 14 years from the date of issue and are not subject to maintenance fees. The filing and issue fees for design patents are much lower than those for utility patents.

What about patents in other countries?
A U.S. patent is in effect within the United States only. It is possible to apply for patents in other countries. International patent applications are a very complex matter, and the body of law regarding them is undergoing some change and reinterpretation. At this time I'm not doing any international patent applications, only U.S. patent applications.

Why should I choose to work with Scott Lefton?
