Patents serve two primary purposes: giving rights to the inventor and preventing others from copying the inventor’s work. That protection is what encourages innovation. However, before you invest time and money in filing a patent, there is a critical step you should not rush through, or worse, skip, and that is the patent search. A comprehensive patent search helps you figure out if your idea is genuinely new or if something similar already exists. Skipping this step could result in wasted development costs, delayed launch, or a rejected application. So, how do you run an effective patent search?

Start With Smart Keyword Searches

From the most basic to the most comprehensive searches, keywords are crucial when conducting a patent search. However, using obvious terms alone may not get you the confidence you need to file a patent. This is because patent documents often use technical or broad language, rather than everyday wording. For example, a coffee cup may be described as a beverage container or a drinking vessel.

As such, a great approach is to list all possible synonyms and build searches around them. You may also consider using Boolean operators like AND, OR, and NOT to narrow or expand the results. Additionally, to prevent your invention from overlapping with international patent filings, include non-English keywords, where possible. This can help avoid missing crucial prior art that may have been captured in other languages, like Chinese or Japanese.

Look Beyond the U.S. Patent Database

While the USPTO database is a good starting point, you should not stop your search there. An examiner could review prior art from anywhere in the world, so it is best to expand your search. Doing this can reduce the risk of overlooking a similar patent filed overseas and also help you assess market realities to inform your decision on how and whether to move forward commercially.

Use Patent Classification Codes

Every patent is assigned classification codes that group inventions by technology area. Identify the proper classification for your invention, as this can help you to quickly locate closely related patents, even if they don’t share obvious keywords.

Search Broader Classifications

One of the most common mistakes people make is searching only for narrow classifications. Patents are sometimes categorized under broader classes, especially when an invention crosses multiple fields. If you limit your search too tightly, you may miss relevant prior art. It’s best to run your patent search in both narrow and broader classifications to ensure you have an idea of the entire landscape and uncover results you might have otherwise missed.

Understand Why You are Searching

It’s essential to understand the goals of your patent search. Are you testing patentability or freedom to operate? If your goal is patentability, you need to determine whether a single document discloses your entire invention or if your idea combines elements that are not disclosed and are likely to be considered inventive. On the other hand, if you are checking freedom to operate, you will need to know whether a relevant patent is still active and if its claims cover your invention. This is where a patent attorney’s guidance becomes especially valuable.
