How Do I Search For Existing Patents?

So you’ve registered to apply for a patent but aren’t sure how to start the search. Well, you can’t do it yourself, but you can hire a professional patent searcher. Patent searchers are specialized individuals who search for patents on a daily basis. They are also more familiar with the patent classification system than patent attorneys or inventors. Here are some of the main ways to search for existing patents.


The process of finding patents is made easier with the invention database Global Dossier. This database includes patents as well as non-patent literature. This software allows users to refine searches and can be used to find patents with a specific keyword. The AI-backed platform ranks results based on their relevance, making the search process easy and intuitive. Listed below are some examples of patent databases that offer similar features.


If you’re researching a new lens design, you may wonder how to find existing patents. While there are a number of free online patent databases, this one is the most effective. Not only can you see all lenses with patents, you can also narrow down your search by using a country filter. Moreover, Lens allows you to filter search results by collaborating countries and authors. It also allows you to view patent full texts and other knowledge artifacts.

This search engine provides access to over a hundred million lenses. You can also perform searches using a filing number or publication number. You can also create an account to export your search data. The database provides detailed information about lenses, including the status of patents and who owns them. It’s also easy to sort and export the results by classification, ownership, and publication date. To start your search, just type in your keywords and select your preferred language.

Once you’ve entered the subject, you can filter the results based on author affiliation. This method gives you more detailed results than the first option, but it does produce fewer results than searching multiple databases independently. You can import records from external databases, too. But you should remember that there are a number of limitations. When searching a database with multiple subject limits, you might find some overlap, but it’s better to check one than a thousand.

The Lens database is a free, online tool that enables users to easily discover scholarly and patent literature. It was launched in 1998 and was initially focused on transparent access to patent literature. Eventually, it will host over ninety-five percent of the world’s patent literature. Recently, Lens has begun to merge scholarly literature into its database. It draws its content from many different providers, including Microsoft Academic Graph and PubMed.


Whether you’re a beginner or an expert in the field, Espacenet is a fantastic resource for your research. It contains data on 130 million patent documents from around the world, and it’s updated daily. The database contains supporting information that helps you understand whether a patent has been granted or is still in force. For example, if you’re looking for a certain type of car, you can search for “automobile” and “automobile.”

To search for existing patents, you can use the “Find” tab to look through the different classification systems. Espacenet provides a list of patent documents for the Cooperative Patent Classification (CPC), a classification system created by the EPO and USPTO. The CPC has more than 260 000 entries and covers all EP, US, and WO patent applications. There are also classes available for several other patent offices around the world, and you can choose from these if you wish to narrow down your search.

Espacenet is the largest patent database available to the public for free. It contains data on over 90 million patent documents from around the world, and it’s free to use. This database is especially useful for people who don’t have access to a patent office. Espacenet also includes a comprehensive list of patent databases in more than 100 countries. It’s best for searching patents worldwide and locating them quickly.

You can also look up U.S. patents using this search tool. The patent search tool is free and allows you to select specific fields in a patent. For example, if you are looking for “automobile” you can use the search bar to search for “automobile.” If you’re looking for patents related to motorcycles, you can use the Google Patents or Espacenet’s other free resources to conduct searches.


If you are trying to discover a new invention, you can search for existing patents on Google. While Google’s patent search is relatively useful, it is not very specific. You may be able to find some prior art, but you will be limited by Google’s algorithm. Here are a few tips for searching for existing patents on Google. First of all, make sure to use a specific search term. It’s helpful to know how to search for prior art in patents so you can avoid the pitfalls that plague the free search engine.

A good way to search for existing patents on Google is to search for the company or inventor you’re researching. Google Patents has an easy-to-use interface, but it can sometimes lack updated data. While USPTO patent search offers the most current data, Google Patents is a good option for beginners and also provides convenient access to patent images in PDF format. If you’re looking for the state-of-the-art and novelty of a particular invention, Google Patents is the right choice.

After entering the keywords you’re looking for, the next step is to choose the patent office. The US is generally the first choice, but you can branch out to other countries. The search will be conducted in the language you specify. You can submit your invention anywhere – including other countries – as long as it conforms to local patent laws. If you want to file a patent in a foreign country, be sure to translate the document into the language of that country.

Another important step when searching for existing patents is to use Google’s advanced search tool. While some free patent databases offer search tools, Google Patents has a more user-friendly interface and a better interface. It also gives you a PDF file for each patent you find, which makes it easy to share with others. In addition, Google Patents’ advanced search tool helps you filter out unrelated patent publications.


You may have already heard of DuckDuckGo, the search engine that prioritizes user privacy over anything else. As of 2018, the company served 9.2 billion searches and saw a 63% increase in traffic compared to the previous year. As a result, DuckDuckGo is rapidly gaining popularity and resources. This upstart search engine has a clean interface and no ads, unlike Google.

During the initial phase of a search for a specific invention, you need to search for existing patents. Several sources, including Wikipedia and regular search engine searches, can be used in a prior art search. However, DuckDuckGo is highly recommended due to its repeatability and personal security. The search engine also pulls business information from Yelp, another popular site for business information.

During the initial phase of your search, enter the terms and phrases that describe your invention into an internet keyword search. While all search engines may appear similar, open, non-tracking search engines are safer and more repeatable. If you are unsure which search engine to use, Carson Patents recommends DuckDuckGo. It is easy to use and gives you access to additional keywords that you may not have thought of.

While DuckDuckGo doesn’t offer as many search results as Google, it has strong privacy policies and is far superior to the other search engines on the market. It’s not the best search engine, but it does try to do right by the users. But don’t let this stop you from searching – DuckDuckGo will give you the results you need. But it’s worth the effort to make sure that you’re not sharing your personal information with anyone.
