The patenting process is rigorous, requiring an invention to be novel, non-obvious, and industrially applicable. A prior art search is a crucial step in this journey, ensuring that an invention does not already exist in some form. However, beyond just being a formality, a well-executed prior art search can define a company’s intellectual property (IP) strategy, mitigate risks, and streamline R&D investments.
Prior art refers to any evidence that demonstrates the existence of an invention or technology before the filing date of a patent application. This evidence can include patents, patent applications, scientific articles, technical papers, product manuals, public demonstrations, or any publicly available information related to the invention. Prior art is crucial in determining the patentability of an invention, as it helps establish whether the invention is new and non-obvious.Â
The presence of prior art can have a significant impact on your patents. If prior art is found that discloses the same invention or renders your invention obvious, it can negatively affect the novelty and inventiveness of your patent application. In such cases, your patent may be rejected during the examination or invalidated if it has already been granted. Prior art acts as a benchmark against which your invention is evaluated, and any similarities or overlaps can weaken your patent claims.Â
A prior art search is not merely a tool for patent filing but a strategic approach to understanding the competitive landscape. A comprehensive prior art search helps companies:
Assess the patentability of an invention – ensuring time and resources are not wasted on filing unviable applications.
Avoid potential litigation – by identifying existing patents that may lead to infringement claims.
Strengthen existing patents – by crafting stronger claims that are defensible in legal disputes.
Refine R&D directions – by identifying gaps in innovation where new patents can be strategically filed.
Understand technology trends – by analyzing how competitors and industries are evolving.
There are multiple types of prior art searches, each tailored to a specific objective. Businesses and legal teams choose the appropriate search type based on the purpose they aim to achieve:
A novelty search is conducted before filing a patent application to determine whether an invention is unique. It involves searching both patent and non-patent literature (NPL), such as research papers, technical articles, and product documentation.
Helps prevent rejection due to lack of novelty
Provides a basis for drafting stronger claims
A patent validity search is performed to either defend a granted patent’s validity or to challenge an existing one in cases of patent disputes.
Used in litigation to invalidate an opposing party’s patent
Conducted by competitors before licensing deals to assess patent strength
Helps patent owners fortify their IP portfolio by identifying weaknesses
An FTO search is conducted before launching a product to ensure it does not infringe on existing patents.
Focuses on legally active patents in specific jurisdictions
Helps companies avoid expensive lawsuits
Aids in decision-making for market expansion
These searches are broader in scope and are used to analyze the technological developments in a particular domain.
State-of-the-art searches are helpful in R&D planning
Patent landscape analysis is used for competitive intelligence, investment analysis, and identifying white spaces in innovation
An infringement search aims to identify patents that may be infringed by a particular product or process. It involves reverse engineering claims in existing patents to find potential legal risks.
Essential before launching a product in competitive markets
Helps in formulating licensing strategies
For industries dealing with chemicals and biological innovations, Markush structure searches (for chemical compounds) and biological sequence searches (for nucleic acid or protein sequences) help in identifying prior art based on molecular similarities rather than textual disclosures.
Critical in pharmaceuticals and biotechnology
Helps in drafting patent applications for drug formulations
Conducting a prior art search is essential for several reasons:Â
The cost of a prior art search can vary depending on several factors, including the complexity of the invention, the depth of the search, the number of databases and sources searched, and the expertise required.
Conducting a basic search on your own using freely available resources can be relatively inexpensive, but it may not yield comprehensive results. On the other hand, a professional prior art search conducted by a research firm or a patent attorney can be more expensive but provides access to specialized databases and expertise.Â
To be considered prior art, the evidence must be publicly available and disclose the invention in a manner that enables a person skilled in the field to replicate or understand it.
The evidence can include patents, patent applications, scientific publications, product manuals, public demonstrations, websites, videos, or any other form of documentation or publication that predates the filing date of the patent application.Â
If you decide to conduct a prior art search yourself, here are some steps to follow:Â
While conducting a prior art search on your own can be a cost-effective option, there are several benefits to getting the search conducted by a research firm or a patent attorney:Â
Prior art search is a critical step in the patenting process, enabling inventors and patent applicants to assess the novelty and inventiveness of their inventions. By identifying relevant prior art, you can make informed decisions, strengthen your patent claims, and avoid potential infringement issues. While conducting a prior art search on your own is possible, seeking the expertise of a research firm or a patent attorney can provide more comprehensive and reliable results. Investing in a thorough prior art search can save time, and resources, and increase the chances of obtaining a strong and enforceable patent.Â
