About patents

What is a patent?

"A patent is an intellectual property right granted by the Government of the United States of America to an inventor “to exclude others from making, using, offering for sale, or selling the invention throughout the United States or importing the invention into the United States” for a limited time in exchange for public disclosure of the invention when the patent is granted.

There are three types of patents.

  • Utility patents may be granted to anyone who invents or discovers any new and useful process, machine, article of manufacture, or composition of matter, or any new and useful improvement thereof.
  • Design patents may be granted to anyone who invents a new, original, and ornamental design for an article of manufacture.
  • Plant patents may be granted to anyone who invents or discovers and asexually reproduces any distinct and new variety of plant."

"Using information from 41 patent-issuing authorities, DII facilitates rapid, precise patent searching, letting you conduct patent and citation searches of inventions in chemical, electrical, electronic, and mechanical engineering. Descriptive titles and indexing have been added. Find “equivalent” patents published in a language you can read. Also contains both citing and cited patents and literature references, allowing users to move both forward and backward in time from a selected patent. Updated weekly, covers 1963-present."

"Espacenet's worldwide database enables you to search for information about published patent applications from over 90 different countries and regions. Espacenet offers free access to more than 70 million patent documents worldwide--most of them patent applications rather than granted patents--from 1836 today. Patent applications normally represent the first publication of a new idea, appearing ahead of journal articles and before new products reach the market. It is possible to print and download full-text documents."

"Updated daily, Scopus is the largest abstract and citation database of peer-reviewed literature. It also includes web sources, patents, articles in-press, book series, conference proceedings, and trade publications. Scopus provides international coverage of literature in science, technology, and medicine, and social sciences plus related content in the arts and humanities. 1996-present plus selected coverage back to 1823."

Scopus offers a patent search of over 24 million records from WIPO, EPO, USPTO, JPO and the UK.  Do your search and after you have results, look for "view patents results" above the search result list.  When you select it, Scopus will open another window with only the patents.  A partial preview of the abstract is available by mousing over the patent title.  Links will take you from Scopus to the patent repository where the full text can be downloaded.
