A patent search is an essential part of the patent process, or the first process, and is used to determine whether an invention is eligible for patent protection. It is also used to determine the validity and invalidity of the patent, identify potential infringement issues pre- and post-patent grant, and take well-informed business decisions. In this blog, we’ll cover the basics of patent search, including why it’s important, the different types of patent searches, and how to conduct a patent search.
Why is patent search important?
A patent search is important for several reasons. First and foremost, it helps the applicant determine whether an invention is eligible for patent protection or not. In order to be eligible for a patent, an invention must be new, non-obvious (inventive step), and have industrial applicability.
A patent search as patentability search helps to determine whether an invention meets all three criteria by searching for similar inventions that have already been patented or published as patent application.
A patent search is also important for identifying potential infringement issues. If you are planning to commercialize a product, process, or method, it is essential to conduct a patent search to ensure that you are not infringing on any existing patents. Infringement can be costly, and result in legal action being taken against you.
Finally, a patent search can be used to make well-informed business decisions. By conducting a patent search, you can gain insights into the state of the art in your field and identify potential opportunities for innovation or licensing. You can also use patent search to assess the strength of your own patent portfolio, or to identify potential gaps that need to be filled.
Types of patent search
There are several different types of patent searches that you can conduct, depending on your needs.
Novelty search: A novelty search is used to determine whether an invention is eligible for patent protection. It involves search for novelty concept of the invention with similar inventions that have already been patented or published, and is typically conducted before filing a patent application.
Patentability Search: A patentability search helps to determine whether an invention meets all three criteria by searching for similar inventions that have already been patented or published as a patent application, an article in a journal, a newspaper, or at a conference.
Infringement search: An infringement search is used to determine whether a product or process infringes on any existing granted patents. It is typically conducted before commercializing a product or process, and can help identify potential infringement issues that need to be addressed.
Freedom-to-operate search: A freedom-to-operate search is similar to an infringement search, but is focused on determining whether a product or process is free to be used without infringing on any existing patents. It is typically conducted before launching a new product or process.
State-of-the-art search: A state-of-the-art search is used to identify the current state of the art in a particular field, and can be useful for identifying potential opportunities for innovation or licensing. It involves searching for patents and published literature in a particular field, and can be useful for gaining insights into the current state of the art.
Validity search: A validity search is used to assess the validity of an existing patent. It involves searching for prior art that may invalidate the patent and can be used to defend against potential infringement suits or challenge the validity of an existing patent.
How to conduct a patent search
There are several steps involved in conducting a patent search:
- Identify your search goals: Before you begin your search, it is important to identify your search goals. Are you going to file for a patent? or looking for similar inventions that have already been patented or published? Are you trying to determine whether a product or process infringes on any existing patents? Are you trying to enforce your patent rights on a infringer? Are you going to launch a new product or method without getting into patent infringement? Are you trying to defend yourself from a patent infringement suit? Understanding your search goals will help you to determine which type of search to conduct and what resources to use.
- Determine your search parameters: Next, you’ll need to determine your search parameters. This will involve identifying the jurisdiction, relevant classification codes for your field of search, as well as relevant keywords or phrases that you want to include in your search and name of the applicants and inventors in the same technological field.
- Choose your search resources: There are several resources that you can use to conduct a patent search, including online databases such as the Google Patents, USPTO Patent Full-Text and Image Database, Patent Scope and the European Patent Office’s Espacenet database, as well as printed resources such as the Official Gazette of the USPTO, the European Patent Office’s Weekly Bulletin and publication of weekly or biweekly journal or gazette of national patent offices. It is often helpful to use a combination of different resources to ensure that you are conducting a thorough search.
- Conduct the search: Once you have identified your search goals, determined your search parameters, and chosen your search resources, you can begin the search itself. This will typically involve entering your search terms into the database or resource that you are using and reviewing the search results.
- Analyse the search results: Once you have conducted your search, it is important to carefully analyse it to determine whether your invention is eligible for patent protection or whether there are any potential infringement issues. This will typically involve reviewing the patents and published literature that are relevant to your invention, and determining whether they are similar enough to your invention to pose a problem.
Conclusion
A patent search is an essential part of the patent process, and is used to determine whether an invention is eligible for patent protection, identify potential infringement issues, and inform business decisions.
