Prior to that date, an estimated 9, patents had been issued. Some patent numbers, as displayed in the table, are 7 characters with the numeric portion padded with leading zeroes. Some numbers within a series may be unused. Therefore, the number of patents granted during a year cannot be determined by simply subtracting the number of the first patent issued in one year from the number of the first patent issued in the next year. The user should note that while the data in this table have been checked, it still is possible that inadvertent errors remain. A detailed Patent Technology Monitoring Team report, titled Issue Dates and Patent Numbers Since , which contains first patent numbers and the day of issue for patents issued since , also may be of interest.

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. A patent gives the owner the right to prevent others from making, using, importing or selling the invention without permission. To be patentable an invention must be, among other things, new, innovative, better or cheaper or different to anything that has been done before.

Historically, the word “patent” was an abbreviation of the term “letters patent” derived from the Latin “litterae patentes”, meaning “open letters”. The document could be read without the seal being broken. Letters patent were used in the Middle Ages for administrative purposes, for example for the grant of titles of honour and the appointment of judges. 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.
