Patent Search: What Is It?  

A patent search is a systematic investigation of existing patents and published applications to determine the novelty and non-obviousness of an invention. The purpose of a patent search is to identify prior artexisting patents and published documentsthat may affect the patentability of an invention. It helps inventors assess the uniqueness of their idea, identify similar inventions, and evaluate the potential for obtaining patent protection. 

Why Is a Patent Search Important? 

  • Assessing Patentability:

    A patent search helps determine if an invention meets the criteria for patentability, namely, novelty and non-obviousness. By uncovering prior art that discloses similar inventions or technologies, inventors can evaluate the potential patentability of their idea and avoid unnecessary costs and efforts. 

  • Identifying Potential Obstacles:

    Conducting a patent search helps identify existing patents or published applications that may pose obstacles to obtaining a patent. By identifying prior art that may be relevant to their invention, inventors can better understand the patent landscape, evaluate the strength of their idea, and make informed decisions about pursuing patent protection. 

  • Supporting the Patent Application Process:

    A thorough patent search provides valuable insights that can strengthen the patent application. It helps inventors identify relevant prior art to ensure the claims are sufficiently differentiated and non-obvious, enhancing the chances of securing a granted patent. 

How Much Does a Patent Search Cost?  

The cost of a patent search can vary depending on various factors, such as the complexity of the invention, the depth of the search, and whether you choose to perform the search yourself or hire a professional. Here are the different options and their associated costs: 

  • Self-Conducted Patent Search:

    Performing your own patent search can be cost-effective, but it requires time, effort, and access to patent databases and resources. Patent databases like the United States Patent and Trademark Office (USPTO) offer free access to their search tools, allowing inventors to conduct preliminary searches at no cost. However, in-depth searches may require access to paid databases or the assistance of a patent search professional. 
  • Hiring a Patent Search Professional:

    Engaging a patent search professional or patent attorney can provide a comprehensive and reliable patent search. The cost of hiring a professional typically depends on the complexity of the invention, the scope of the search, and the experience of the professional. The price can range from a few hundred dollars to several thousand dollars. 

Performing Your Own Patent Research 

Performing your own patent search can be a cost-effective option if you have the time, resources, and access to patent databases. Here are some steps to help you get started: 

  • Define the Scope of the Search:

    Clearly define the technical aspects and keywords related to your invention. This will help narrow down the search and make it more focused. 

  • Use Patent Databases:

    Leverage online patent databases such as the USPTO, the European Patent Office (EPO), or the World Intellectual Property Organization (WIPO). These databases provide access to extensive collections of patents and published applications. 

  • Use Advanced Search Techniques:

    Learn how to use the advanced search functionalities provided by patent databases. These tools allow you to refine your search using specific criteria such as keywords, inventors, classification codes, and publication dates. 

  • Analyze Relevant Patents:

    Carefully review the patents that are relevant to your invention. Understand the claims, specifications, and drawings to determine their relevance to your idea. 

  • Document and Organize:

    Keep detailed records of the patents you find during your search. Document relevant information such as patent numbers, inventors, and key excerpts for future reference. 

What Other Costs Are Associated With Getting a Patent? 

It is important to note that a patent search is just one aspect of the overall cost associated with obtaining a patent. Other costs include:

  • Patent Application Filing Fee:
    The cost of filing a patent application varies depending on the jurisdiction. Different countries have different fee structures, and additional fees may apply for multiple claims or pages. 
  • Patent Attorney or Agent Fees:
    Hiring a patent attorney or agent to assist with the drafting and filing of the patent application incurs additional costs. Their expertise ensures that the application meets the legal requirements and increases the chances of success. 
  • Patent Examination and Prosecution:
    Once the application is filed, there may be additional costs associated with responding to office actions, conducting amendments, and communicating with patent examiners during the examination and prosecution process. 
  • Maintenance Fees:
    After the patent is granted, maintenance fees are required to keep the patent in force. These fees vary depending on the jurisdiction and the length of time the patent is maintained. 

Is The Preliminary Search The Only Expense? 

No, the preliminary search is just the initial step in the patent search process and is often the least costly part. Conducting a thorough and comprehensive search can involve additional expenses if you choose to hire a professional or use paid databases for more in-depth research. The cost of a patent search should be viewed as an investment in the overall patenting process and the protection of your intellectual property.

Frequently Asked Questions  

  • Can I conduct a patent search myself?

    Yes, you can perform your own patent search using online patent databases and resources. However, it is recommended to consult a patent attorney or search professional for a more comprehensive and reliable search. 

  • What if I find similar patents during my search?

    Finding similar patents does not necessarily mean that you cannot obtain a patent. A patent attorney can help assess the differences between your invention and the prior art, and guide you on the best approach moving forward. 

  • How long does a patent search take?

    The duration of a patent search can vary depending on the complexity of the invention, the depth of the search, and the resources available. It can take anywhere from a few hours to several weeks. 

  • Can I perform a patent search after filing a patent application?

    Yes, you can conduct a patent search after filing a patent application. However, it is recommended to conduct a search before filing to ensure that you are aware of any prior art that may impact the patentability of your invention. 


A patent search is a critical step in the patenting process, helping inventors assess the patentability of their ideas, identify potential obstacles, and make informed decisions. The cost of a patent search can vary depending on factors such as the complexity of the invention and the chosen approach. While conducting your own search can be cost-effective, hiring a professional provides expertise and ensures a comprehensive search. Remember that a patent search is just one part of the overall cost of obtaining a patent, which includes filing fees, attorney fees, and maintenance fees. By investing in a thorough patent search, inventors can protect their intellectual property rights, enhance the strength of their patent application, and navigate the patent landscape with confidence.
