One of the key aspects of the patent application process is conducting a thorough patent prior art search. This search involves exploring existing inventions and disclosures to establish the novelty of your invention.

The Importance Of Patent Protection

Why is patent protection so vital? Patents are an important form of intellectual property protection. They are often the first line of defense against patent infringement. A patent, in theory, allows you to prevent others from making and selling your invention for a certain period of time (usually 20 years). Without this protection, competitors could freely copy your patent and sell their own version of it.

Importance of a Prior Art Search

A prior art search is fundamental in determining the patentability of your invention. It aids in the following aspects:

  • Novelty Assessment: Fulfills an essential prerequisite for patentability as it assesses if your invention is indeed new.
  • Non-obviousness Evaluation: Assists in determining if your invention is not an obvious improvement of an existing one, another important criterion for patentability.
  • Patent Drafting: Helps define the scope of your invention and supports in drafting a strong patent application.

Resources for Conducting a Search

There are several databases and tools one can use to conduct a competent prior art search:

  • USPTO Patent Database: Comprehensive resource of all issued U.S. patents and published U.S. patent applications.
  • Google Patents: Free and user-friendly tool to find both U.S. and international patents and patent applications.
  • Espacenet: A free database by the European Patent Office that provides access to international Patent documents.
  • Patentscope: Operated by the World Intellectual Property Organization with access to international Patent Cooperation Treaty (PCT) applications.

What to Look for and Document

When conducting a prior art search, it’s crucial to know what to search for and to attentively document the findings. Here’s what to consider:

  • Similar Inventions: Look for inventions that have similarities with your proposed idea. Pay attention to their claims and descriptions which might overlap with your invention.
  • Document Thoroughly: Document your findings meticulously with the patent numbers, patent titles, summaries, and how they relate to your invention.
  • Non-Patent Resources: Do not limit your search to patents alone; consider other resources such as journals, articles, or product catalogs.

Patent Assistance Agencies Can Help

There are professional agencies like InventHelp that assist inventors with their patent search and registration needs. But that’s not all, there are other ways in which InventHelp can assist. They have a team of professional writers that can help you write your patent application and marketing materials. They also have a network of manufacturers and marketers who can assist with product development, and more.


A well-conducted prior art search is an important step in the patent application process. It helps establish the novelty of your invention, aids in the patent drafting process, and prevents possible conflicts down the line. Make use of the available resources and remember to document your findings judiciously. While conducting a prior art search can be time-consuming, the insights it provides can be invaluable.
