Q: How do I know if my product has been patented by someone else?

A: The best way to determine prior patent status of a product is to engage with a patent professional to engage in a freedom to operate search. Prior to that step though, to determine if your product has been patented by someone else, consider the following:

First, understand that patents cover inventions or discoveries that are new, useful, and non-obvious. This includes processes, machines, articles of manufacture, or compositions of matter.

Then, you can start by performing your own patentability search. Start with the United States Patent and Trademark Office (USPTO) database. This database includes all granted patents and published patent applications in the U.S. If you think the patent might be filed in other countries, check international databases such as WIPO’s PATENTSCOPE or the European Patent Office’s Espacenet. This is a user-friendly tool that also includes patents and applications from multiple countries. During your search, use relevant keywords that describe your product’s purpose, composition, and use. It will help to learn aboutm understand and use the Cooperative Patent Classification (CPC) system to find patents in similar categories.

Initially, focus on the abstracts and claims of each patent document. The claims section is particularly crucial as it defines the scope of the patent protection. Also review any drawings or diagrams that might give you a clearer idea of the patented invention. For any patent that seems relevant, read through the entire document carefully to understand the scope of the patent and how it might relate to your product. Make a note to follow up on this with a patent professional.

If you find the process challenging or if there are potentially overlapping patents, consider consulting with a patent attorney. Schell IP (https://www.schellip.com) provides free initial consultations which can be scheduled via the website. They can provide a professional opinion and help navigate potential patent infringement issues.

By following these steps, you can research whether your product or a similar one has been patented as an initial step prior to engaging with a patent lawyer, helping you navigate potential legal considerations before launching or continuing your product development.

A: To find out if your sandal concept has already been patented, start by conducting a patent search. You can use the United States Patent and Trademark Office (USPTO) website, which has a searchable database of patents. Enter keywords related to your sandal design and review the results to see if any existing patents are similar to your idea.

Another useful resource is Google Patents, which allows you to search for patents from various countries, providing a broader scope. Pay attention to the descriptions, claims, and drawings of the patents you find to compare them with your concept. This will help you determine if your idea has already been covered by an existing patent.

If you find similar patents but are unsure if they cover your specific design, consider seeking help from a patent attorney. They can provide a professional opinion on the scope of the patents you find and guide you on the next steps for protecting your unique concept.
