What is the Purpose of a Patent Search?

Before filing a patent, a patent search is conducted to find the closest prior-art and evaluate whether the subject matter/invention is patentable. This stage allows businesses to avoid the costs of patent prosecution if an innovation is denied. Due of the time commitment of doing patent searches in-house, organisations either conducts them with limited resources or outsource them.

A patent is a legal document that guarantees that your inventions will not be used or profited without your permission. One of the best ways to defend yourself from patent infringement is to conduct a patent search. Aside from the apparent advantages, there are several advantages to conducting a patent search. Some of them are listed below:

Investing mistakes can be costly.

You’ll be in a better position to make future decisions about your invention’s patentability once you’ve determined whether it’s patentable.

Prepare yourself by familiarizing yourself with previous works of art.

Understanding the patentability of your invention and drafting unique claims and descriptions for it is easier when you are familiar with prior art.

Enhance your patent application or design in whatever way you can.

Inventors can profit from becoming more aware and familiar with the literature accessible in their field of innovation by using this knowledge to strengthen their patent application or establish a design around strategy.

How to Conduct Your Own Patent Searches?

To conduct a patent search through the USPTO (US patent search) or other online patent search engines (global patent search), follow these steps:

1. Create a keyword list

If the patent search tool you’re using has more advanced search tools, such as semantic search, you can start your patent search by selecting a relevant keyword. Such elements may aid in determining your search intent and delivering the most accurate results.

2. Using your term, locate the appropriate CPC classification.

Once you’ve determined which CPC classification is most applicable to your idea, you can delve deeper and look for patent documents that are relevant. With the most relevant CPC classification that you previously defined, search through the patent documents of both PatFT (issued patents) and AppFT (published patent applications).

You’ll need to search The Published Patent Applications Database and The Complete Patent Documents Database during your patent search in the United States.

When you use other online patent search engines to conduct a global patent search, you’ll notice that many of them will return both granted patents and published patent applications in one search. You may instantly narrow down your search scope for more particular results using advanced filters.

3. Use the citations of the previous art of the most relevant patents from your search to look for other related patents.

After you’ve located the patent applications and issued patents that are the most similar, you can broaden your search by looking at their forward and backward citations. Layer by layer, going through the citations and prior art can help you acquire the most thorough results.

Some internet search engines have search options that can save time by eliminating the need to sift through citations layer by layer. Using such tools and algorithms to do a patent search may show to be a more efficient and user-friendly method.

4. Repeat the process to delve deeper and widen the scope of your search.

It’s crucial to check into non-US patents and non-patent literature in other authorised patent offices to extend your search reach. Examining a patent’s family tree is also a wonderful approach to learn about related patents from other nations.
