Is my invention patent eligible?

The Supreme Court has resolved that "anything under the sun, made by man" is patentable...so long as all of the requirements of the Patent Laws (Title 35 of the United States Code) are met.

What does that mean?

Patentable subject matter includes any process, machine, article of manufacture, composition of matter, or any new and useful improvement thereof.

Aside from falling into one of these categories, your invention must be Useful, Novel and Non-Obvious. This may seem simple enough, but the Patent Rules are both statutory and judicial in nature, and thus often dynamic. Therefore patent applications often require the skill and legal knowledge of a licensed professional. No one can guarentee that you will receive a patent. But with a knowledgeable practitioner, your application will be better represented in front of the Patent Examiner, and your position will be strengthened.
