Before you start a new application, you should check that your invention has not already been patented. How you search for patent information will depend on your goals and what you know already. Your search could be focussed on the relevant technology, the markets you are interested in, or perhaps what your competitors have protected. For example, researching an invention can involve keyword or classification searches on different databases.

This type of research can take time and be complex. In contrast, searching for an existing patent can be simple if you know the country and have a reference number. To make searching easier, every patent is classified by its subject matter. Patent classification schemes have a tree-like structure, and every level of classification has a unique reference code.

Inventions are grouped into technologies eg engineering , divided into classes eg mechanical engineering , and then into subclasses eg machines or equipment for baking. Classification codes can be a useful tool when researching inventions. Keyword searches alone for example can lead to very large numbers of results. Using classification codes together with keyword searches can help you focus results to a more manageable level. Typically, searchers will prepare a list of keywords that describe the invention and identify relevant classification codes.

According to the British Library’s guide, Brief introduction to patents and patent searching , a patent protects new inventors and covers how things work, what they do, how they do it, what they are made of and how they are made.

When monopolies came to be granted for inventions, the grants were made with letters patent.

By the nineteenth century, patents of invention so greatly outnumbered other letters patent, that the word “patent” came to be associated with inventions. The number and year of the patent are essential to know if you wish to view a patent. There are two basic steps to finding a patent: look up an index to find the patent number and year, then ask a librarian to request the patent using the number and year.
