Patent Search Cost: Everything You Need to Know

A patent search cost can be anywhere from $100 to $3,000 depending on the complexity of your invention and covers research into existing patents and patent applications. You can use free online tools to do your own search, but an attorney can help you dig deeper. In addition to professional fees, expect to pay a government search fee after you submit your patent application.

There are a few types of patent searches:

A patent search involves going through patent databases, scientific journals, and other relevant publications.

Professional patent researchers are familiar with how to compare inventions and sift through databases. They understand the wording and drawings in patent applications. They produce reports that highlight any information that relates to the goal of your patent search. The researcher may also offer an opinion about whether an inventor's idea will qualify for a patent.

Researchers use a range of techniques to complete a search. They use both keywords and the cooperative patent classification, which is a system in the U.S. and Europe that groups patents according to invention type.

Why Is a Patent Search Important?

A patent search offers several important advantages:

You can choose not to do a patent search, but this is not wise. Even though the USPTO will do a search for similar patents when you submit a patent application, this search is not as extensive as what a professional researcher would do. Therefore, even if you receive a patent, another person or company might later perform research that makes your patent invalid.

Once you have the results of a patent search, you can feel more confident about sending your patent application to the USPTO.

How Much Does a Patent Search Cost?

Professional Search Fees

Professionals have different methods of charging for patent research. Some charge a flat rate, while others have an hourly fee. This hourly fee often applies if you want the researcher to sort through the information and offer an opinion on the patentability of your invention. Of course, these fees depend on who is doing the research and the type of invention that they'll be researching.

If your invention is fairly simple, you might pay as little as $100 for the search if you hire a service that doesn't offer an in-depth opinion or analysis. For more complex inventions that require deeper research, you might end up paying $2,000 or more. Here are some ballpark estimates for what you might pay if you hire an attorney:

Some businesses frequently need to do patent research. If this is true for you, you may want to subscribe to advanced patent research tools and services instead of paying a separate fee for each search.

Government Search Fees

After you submit your application, the patent examiner assigned to your case will perform a search related to your patent. If you are a small entity, such as a small business or a university, the search fee is $300. For larger businesses, the fee is $600. You can visit the USPTO website for more information about government search fees.

Performing Your Own Patent Research

If you are on a limited budget, you might want to skip a professional search and do your own research. The USPTO has a detailed tutorial on how to do your own preliminary patent research.

There are many online resources you can use to do your research, including:

When you're using a research tool, look at all the available tutorials for that tool so you use it to the greatest advantage.

When doing research, use all possible keywords that might relate to your invention. For example, you might want to patent a mouse trap. Don't just search for "mouse trap." Search for "rodent trap" and any other similar terms you can think of.

You also have an offline patent research option. Every state has at least one Patent and Trademark Depository Library. The librarians there can give you tips on how to do a patent search.

You'll find a lot of irrelevant patents during your search. To narrow your results, try searching for patents that belong to your competitors. This trick is particularly useful in industries where only a handful of companies are prominent.

What Other Costs Are Associated With Getting a Patent?

A patent gives you a monopoly on your invention for 20 years, which is why many inventors choose to pursue patents despite the costs associated with the process. In addition to the research fees, you will have to pay:
