Judge the marketability of this idea before investing any money into it since obtaining a patent is completely different from marketing and selling a product or licensing the patent to allow someone else to market and sell a product.
I believe food can be patented if the patent covers composition of the food or a unique, novel, unobvious, and useful method of manufacture of said food. However, with food, all it takes is one recipe or custom from some rare part of the world to invalidate said patent.
Companies will not discuss the idea with you since they will either steal it and use it without compensating you or they will be afraid you will sue them for any similar future product or method of manufacture they may develop. If they talk with you, they will limit their future development of new ideas but if they do not talk with you then they are free to create whatever they think of.
Methods of action include manufacturing, marketing, and selling the product yourself while keeping your idea as a trade secret or obtaining a patent. Once a patent is obtained then you are able to restrict others from manufacturing, marketing, and selling a product similar to your patent.
If you want to know how to start, you start by researching the patent archives and researching any related prior art (previous patents teaching your invention). You will want to improve upon any prior art already in existence. Here is the
USPTO Search Page.
The other useful thing to do is read David Pressman's
Patent it Yourself. My local library has four copies and they are usually unavailable.
Here is some information from the slides of a presentation I provided a couple years ago.
What can be patented?
Any person who invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent.
- Process ? process, act, or method
- Manufacture ? articles which are made
- Composition of matter ? chemical compositions such as mixtures of ingredients and new chemical compounds.
What cannot be patented?
- Inventions useful solely in the utilization of special nuclear material or atomic energy for nuclear weapons (Atomic Energy Act of 1954)
- Non-useful or non-working machines, it must have utility
- Laws of nature, physical phenomena, and abstract ideas
- A patent cannot be obtained upon a mere idea or suggestion, a complete description is required.
Legal requirements for a utility patent
- Statutory Class Utility
- Novelty
- Unobviousness
Statutory Classes
Does the invention fit into one of five classes established by Congress?
- Process (method)
- Machine
- Article of manufacture
- Composition ? includes chemical composition
- Or, a "new use" of one of the first four.
Novelty
- Does the invention have an aspect that is different in any way from all previous inventions and knowledge?
- Physical differences
- New combinations
- New use
- An invention cannot be patented if:
- the invention was known or used by others in this country, or patented or described in a printed publication in this or a foreign country, before the invention thereof by the applicant for patent, or
- the invention was patented or described in a printed publication in this or a foreign country or in public use or on sale in this country more than one year prior to the application for patent in the United States?
Unobviousness
A patent may be refused if the differences between the invention and prior art are obvious
- Prior art ? the state of knowledge existing before the date of the invention
- If someone skilled in the art would obviously consider the subject matter sought to be patented while implementing any prior art
- Substituting materials or changing size are ordinarily obvious
- New and unexpected results
- Three criteria for non-obviousness:
- Commercial success
- Long-felt but unsolved need
- Failure of others to come up with your invention
