What is a patent?
In exchange for the complete disclosure of an invention, a patent grants the applicant the exclusive right to make, use, or sell the claimed invention for a limited period of time. Patents and patent applications are a great way to learn about an industry or technology. Much of the information in patents will not be available elsewhere.

Searching the patent literature
Concept-based searching
In order to pull up all relevant patents, it is important to search by concepts. Terminology is always changing and varies around the world.
- Visit our concept mapping guide to learn how to extract the main concepts and map out knowledge around an invention.
- Try out a concept mapping software, like the freely available CmapTools (more information about CmapTools).
- Brainstorm synonyms, antonyms and alternative ways of capturing each concept.
- Build a search by combining different terms for a concept with "OR". Here is an example for teapots (the * or truncation symbol can represent any letter and picks up the plural, teapots):
- teapot*
- tea OR teas
- pot OR pots OR pottery
- #2 AND #3
- #1 OR #4
- Take advantage of patent classification codes. For example, A47G 19/14 is the IPC code for "Coffee or tea pots" and can be added to the above search.
