Google Patents is a new search service Patent Search released by Google in December 2006, which allows users to search all US patents, including their image information, patent numbers, inventors, and publication dates.
About Google Patents Google Patents currently covers 17 patent offices and provides more than 87 million patents. Full-text searches include major patent offices such as the United States Patent and Trademark Office (USPTO), the European Patent Office (EPO), the State Intellectual Property Office of China (SIPO), the Japan Patent Office (JPO), the Korean Intellectual Property Office (KIPO), and the World Intellectual Property Organization (WIPO). In addition, Google Translate has translated all non-English patents into English. Google Patents can also search technical documents and books in Google Scholar and Google Books. Combined with the world's leading search technology, Google Patents is the most powerful tool among free patent search databases. use In addition to entering a single search term in the search box, you can also enter text fragments for searching. In addition to English, you can also search in other non-English languages such as Chinese, Japanese, Korean, etc.
Precautions If you use lowercase "or" to search for "or" in Google, the search results are the same as the "space and" search results. In fact, both search for the "and" relationship. In other words, lowercase "or" also performs an "and" search. Since the search shows more relevant results, it is difficult for people to find out that they are wrong. Therefore, when searching in Google, you must remember that for "or" search, you must use uppercase "OR" as the operator, while lowercase "or" represents "and" operation. So, why is lowercase "or" an "and" search? This is related to Google's word indexing rules. In order to improve the efficiency of the operation, Google ignores a large number of function words, conjunctions, punctuation marks, etc. Therefore, "lowercase or" is equivalent to "spaces", which is why it is an "and" search. develop - Google Patents was updated in 2012 to cover the European Patent Office (EPO) and prior art finder tools. - In 2012, Google Patents also launched a special "Prior Art Finder" tool. When we enter a single patent, a "Find Prior Art" button will appear. By clicking this button, keywords can be automatically extracted from the patent document and a search formula can be formed for retrieval. At the same time, the publication date will be restricted, and only documents before the priority date will be retrieved. - In 2013, it was expanded to the World Intellectual Property Organization (WIPO), the German Patent Office (Germany: Deutsches Patent- und Markenamt, DPMA), the Canadian Intellectual Property Office (CIPO) and the State Intellectual Property Office of China (SIPO). All foreign patents are also translated into English and searchable. Chinese patents include not only the invention title, abstract, applicant and other bibliographic items, but also the full text of the patent claims and the specification, and also provide PDF full text download. - In 2015, a new version was launched on patents.google.com, which included a new user interface, integration of Google Scholar with machine classification and the Cooperative Patent Classification (CPC), and clustering of search results to CPC. - In 2016, coverage for 11 additional patent offices was announced. Support for USPTO and EPO Boolean search syntax (proximity, wildcards, title/abstract/claim fields) was introduced, as well as visual graphs of inventor, assignee and CPC by date, thumbnail grid view of search results and downloadable result sets as CSV. - In 2018, global litigation information was added. The Google Patents page shows where in the world the patent (or any member of its family) has a litigation history, and provides a link to the Darts-ip patent case database. |
