A list of five patent search engines and databases

The five best patent search engines to search for patents are PatentScope, Espacenet, The Lens Org, and Design View. All five of these databases for patents in India will be discussed in detail in this blog.

In a company’s lifecycle, patent searches are crucial in providing stakeholders with vital feedback, enabling them to better manage their investments and risks. Patent searches may be tailored to suit the specific business goals being pursued at any given time depending on their objectives.

In addition to patent registration, patent rights may be abandoned, products may be introduced, or patent claims may be asserted against a competitor. Inadequate or incorrect information can negatively affect a company’s financials and operations in the long run.

Patent searches are therefore conducted by both internal and external experts for all major corporations. We discussed our methodology for selecting non-patent literature search engines and bibliographic databases in the post preceding this one. Anybody can use these five free patent search engines below to find information about patents.


Patent Searching Databases: what are they and how do they work?

During the patentability search process, a patent searching database is an online resource that assists inventors, intellectual property specialists, and legal professionals in obtaining rapid and trustworthy results. In addition, innovative individuals and businesses are often supported by intellectual property law firms that rely on these widely-accepted patent search databases to search for existing prior art in the form of patents.

Such databases decrease the amount of time required to obtain information, analyze possibly relevant findings, and provide a report that you can use for practical purposes.


Five Patent Searching Tools That You Should Know About 


Google Patents

One of the most innovative intellectual property search databases was created by Google in 2006. Several patent searching software packages do not perform a comprehensive novelty search for future patents, so this software is crucial for intellectual property law firms. In this regard, Google Patents should always be double-checked. It’s as simple as using Google Search to search for the relevant patent name. A link to the patent itself is often displayed as the first result. The massive Google Patents database has 87 million patents in total, including patents from America, China, Japan, Korea, and Europe.



There is no better IP search database available at the moment than this one. It combines the resources of more than 98 patent organizations around the world. This free IP searching database helps intellectual property law firms provide better services to their clients.

Spacenet’s patent database contains over 110 million patents that can be accessed from the website. Consequently, patent art and patent novelty searches can be resolved in some of the most challenging ways.

This IP searching database offers Smart Search, Advanced Search, and Classification Search tools for searching IP addresses. For intellectual property law firms searching for patents on a specific subject matter, the Advanced Search tool is beneficial since it allows searching by publication number, application number, priority number, inventor’s name, and publication date.


The Lens Org

In addition to being one of the earliest digital patent searching databases, the Lens Org should be familiar to all patent lawyers. This open database (EPO) includes information from top patent authorities around the world, including the USPTO, the WIPO, and the European Patent Office. A total of over 81 million documents are included in the database, including patent bibliographic data from the European Patent Office (EPO) from 1907, USPTO patent applications from 2001, USPTO patents (granted) from 1976, more than 14 million USPTO assignments, EPO patent grants from 1980, WIPO patent applications from 1978, and full-text patents from IP Australia.


In addition to a comprehensive database, the Lens Organization offers numerous types of metadata searchability ranging from publication dates, filing dates, priority dates, and extended patent family sizes. For patent lawyers seeking a user-friendly, readily accessible worldwide patent database, this database is invaluable. Aside from United States patents that have lapsed, abandoned, or expired, you may also search for them using INPADOC’s patent status and family information service. PDF files can also be used to visually represent patent families.

On lens.org, the website suggests dynamic charts as another useful feature for analysing information.



Online patent search database PatentScope is a free service provided by the World Intellectual Property Organization. This browser-based patent searching database provides access to all PCT applications worldwide in their full-text versions. The other cooperating regional patent administrations have also contributed patent papers to this database.


Design View 

You can search for design patents in DESIGN View, a free online database. As of 2012, this database has become increasingly popular (EUIPO) because of its launch by the European Union Intellectual Property Office. Around 16,941,630 registered designs are included in this database, which is searchable across 72 countries. Using this database is a breeze thanks to its user-friendly interface. A basic search or an advanced search can be used to narrow the search scope. Furthermore, this database allows for a side-by-side comparison of designs. Moreover, it is available in 37 languages, allowing patent attorneys to search for patents in the language they are most comfortable with.



Patent search databases have the potential to drastically reduce the turnaround time for patent searches after reading this essay. Patent lawyers may also benefit from the same technologies by streamlining the patent search process, navigating through significant patent papers effectively, and drawing better conclusions.
