Patent Search Engines and Databases

Patent Search Engines and Databases

The five best patent search engines are PatentScope, Espacenet, The Lens Org, Design View, and Google Patents. We will discuss in detail all 5 of these patent databases in India in this blog. 

As a company’s lifecycle unfolds, patent searches can provide critical feedback to stakeholders, allowing them to better manage their investments and risks. It is possible to tailor the objectives of a patent search depending on the specific business goals being pursued at the time.

A patent registration may be one of these objectives, as well as the abandonment of patent rights, the introduction of a product, or the assertion of a patent claim against a rival. A company may suffer financial ramifications and long-term effects from acting on incomplete or incorrect information.

Thus, all major corporations hire qualified in-house and outside experts to perform patent searches on their behalf. We discussed our methodology for selecting free academic search engines and bibliographic databases for non-patent literature searches in the preceding post. Following are our top five picks for free patent search engines, which anybody can use to find patent information.

What Are Patent Searching Databases?

A patent database can provide rapid and accurate results to an inventor, intellectual property expert, or a legal professional as part of the patentability number search process. Moreover, many intellectual property law firms help innovative individuals and businesses identify prior art that exists in the form of patents by utilizing these widely-accepted patent search databases.

Databases of this type enable you to quickly gather information, analyse possible findings, and generate a report for practical use.

Five Patent Searching Tools That You Should Know About

Google Patents

It was developed by Google in 2006, and is considered to be one of the most creative intellectual property search databases available. Software packages that perform a comprehensive novelty search for future patents are essential to intellectual property law companies since few patent searching software packages perform such a search. It is, therefore, a good idea to double-check with Google Patents. By simply typing the relevant patent name into Google Search, you’ll be on your way. In addition to this, the first result is often a direct link to the patent itself. The massive Google Patents database, which has 87 million patents in total, includes patents from nations such as the United States, China, Japan, Korea, and Europe.


IP Search is one of the most comprehensive databases available today. It allows you to access the resources of patent organisations from over 98 different countries. Thus, law firms offering intellectual property services can better serve their clients by using this free IP database.

More than 110 million patents are available in Spacenet’s patent database. As a result, it can help intellectual property firms deal with some of the toughest challenges they encounter when conducting patent art and novelty searches.

The IP searching database offers three types of search tools: Smart Search, Advanced Search, and Classification Search. The Advanced Search tool is useful for intellectual property law firms looking for patents on a specific subject matter because it allows searches by publication number, application number, priority number, inventor name, and publication date.

The Lens Org

Patent lawyers should be familiar with Lens Org, one of the earliest digital patent databases. As an open database (EPO), it compiles information from the world’s top patent authorities, including the United States Patent and Trademark Office (USPTO), the World Intellectual Property Organization (WIPO), and the European Patent Office. More than 81 million documents were found in the bibliographic database of the European Patent Office (EPO) from 1907 to 2001, USPTO patent applications from 2001 to 2006, USPTO patents (granted) from 1976 to present day, USPTO assignments dating back more than 14 years, EPO grants from 1980 to present day, WIPO patent applications from 1978 to present day, and full-text patents from IP Australia.

A wide variety of metadata can be searched through Lens’ extensive and comprehensive database, including publication, filing, priority, and extended patent family sizes, among other things. For patent professionals looking for an easily accessible, user-friendly, worldwide patent database for their clients, this database is invaluable. Additionally, you can search for lapsed, abandoned, or expired U.S. patents in your area by using the INPADOC patent status and family information service. The graphical tree format in PDF may also be used to represent patent families. also offers dynamic charts that may be useful for analyzing information, according to the website.


PatentScope is a free patent search database maintained by the World Intellectual Property Organization. Through this browser-based patent search database, patent applications worldwide filed under the Patent Co-operation Treaty (PCT) are now available in full-text versions. In this database, it has also included patent papers that have been registered under the jurisdiction of other cooperating regional patent administrations.

Design View

You can search for design patents using DESIGN View, an online database that is free to use. Several years ago, the European Union Intellectual Property Office (EUIPO) launched a database of this type, which has since grown in popularity (EUIPO). A total of 16,941,630 registered designs are available in this database, which has been compiled from 72 national offices worldwide. Accessing this database is a breeze thanks to its intuitive interface. The basic search and advanced search can be used to narrow the scope of the search. Also, these databases enable side-by-side comparisons between designs. Furthermore, it is available in 37 languages, allowing patent lawyers to conduct patent searches in the language they are most comfortable with.


I think that it should be clear to any reader after reading this essay that patent search databases have the potential to drastically shorten the turn around time for patent searches. As well as streamlining the patent search process, navigating through significant patent papers effectively, and drawing the most effective conclusions from them, the same technologies may also assist patent lawyers to streamline the patent search process.
