Prior Art Searches & Patentability Analysis

Evaluating an Invention Before Filing 

Not every new product or technical improvement qualifies for patent protection. Before investing in a patent application, evaluate whether earlier patents, publications, products, or technical disclosures could affect patentability. 

​

A prior art search can identify existing references related to an invention and provide useful information about the surrounding technology. A patentability analysis can then assess how those references may affect the ability to pursue patent protection. 

​

Use this process to make a more informed decision about whether, when, and how to file.

What Is Prior Art? 

Prior art may include information that became publicly available before the relevant patent filing date. 

Potential prior art can include: 

  • Issued U.S. and foreign patents  

  • Published patent applications  

  • Scientific and technical articles  

  • Product manuals and catalogs  

  • Conference presentations  

  • Academic publications  

  • Publicly available software or documentation  

  • Existing products and commercial systems  

  • Online publications and other public disclosures  

The relevance of a reference depends on its publication date, technical content, and relationship to the proposed invention. 

Prior Art Search Services 

Conduct targeted searches focused on the invention’s key features and potential points of novelty.

Search services may include: 

  • Reviewing the invention and its technical components  
     

  • Identifying important search concepts and terminology  
     

  • Searching U.S. and international patent databases  
     

  • Reviewing patent classifications  
     

  • Locating related technologies and references  
     

  • Comparing search results with the proposed invention 
     

  • Organizing potentially relevant prior art  
     

  • Highlighting references requiring closer analysis  

Searches may be adjusted based on the technology, complexity of the invention, and intended use of the results.

The analysis does not guarantee that a patent will issue. It provides a strategic assessment based on the information available before filing. 

Patentability Analysis 

After relevant references are identified, evaluate whether the invention may satisfy key patentability requirements. 

A patentability analysis may consider: 

  • Whether the invention appears novel  
     

  • Whether the differences from earlier references may be non-obvious  
     

  • Which features appear most distinguishable  
     

  • Whether the invention may fall within patent-eligible subject matter  
     

  • Whether the invention can be described with sufficient detail  
     

  • Whether claim scope may need to be narrowed  
     

  • Whether additional development may improve the filing position

Using Search Results to Improve a Patent Strategy 

Prior art search results can guide more than a yes-or-no filing decision. 

Results may help: 

  • Refine the invention’s strongest features  

  • Focus the patent application on meaningful distinctions  

  • Reduce time spent pursuing overly broad concepts  

  • Identify crowded areas of technology  

  • Reveal potential competitors or licensing opportunities  

  • Guide future research and development  

  • Support conversations with investors or business partners  

  • Determine whether a different form of IP protection may be more appropriate  

In some cases, the search may support moving forward with a full application. In others, it may suggest revising the invention, narrowing the filing strategy, or redirecting resources. 

Who Should Consider a Patentability Search? 

A prior art search may be useful for:

Search services may include: 

  • Individual inventors  
     

  • Startups preparing to file a patent application  
     

  • Companies evaluating new product concepts  
     

  • Engineering and research teams  
     

  • Businesses considering acquisition or licensing opportunities  
     

  • Investors reviewing technology-based ventures  
     

  • Product developers deciding where to allocate resources  

Searches may be adjusted based on the technology, complexity of the invention, and intended use of the results.
