Conducting a thorough patent search is an essential part of the patent process, and can help to ensure that your invention is eligible for patent protection, identify potential infringement issues, and inform business decisions. While the basics of patent search are relatively straightforward, there are a number of advanced strategies that you can use to conduct a more thorough and effective patent search.
- Use multiple search tools and resources: One advanced strategy for conducting a patent search is to use multiple search tools and resources. While online databases such as the USPTO Patent Full-Text and Image Database and the European Patent Office’s Espacenet database are a good place to start, it is often helpful to use a variety of other resources as well. This might include printed resources such as the Official Gazette of the USPTO and the European Patent Office’s Weekly Bulletin, as well as specialized search tools and databases that are specific to your field of interest. By using multiple resources, you can increase the chances of finding relevant patents and published literature.
- Utilize advanced search techniques: Most patent search tools and databases offer advanced search options that allow you to narrow or expand your search criteria. Various operators are used in these patent database to narrow or expand you search criteria. For example, you can use wildcard characters (such as an asterisk) to search for variations of a word, or use boolean operators (such as AND, OR, and NOT) to specify the relationships between different search terms. (Near OR ADJ OR SAME or similar operators are proximity based operators which search for phrases within the proximity of other phrase or word. By using these advanced search techniques, you can more effectively target your search and find relevant patents and published literature.
- Consider non-patent literature: In addition to searching for patents, it is also important to consider non-patent literature such as technical articles, conference proceedings, and dissertations. These types of literatures can also provide valuable insights into the state of the art in your search field, and can help you to identify potential gaps or opportunities for innovation.
- Use patent classification codes: Patent classification codes are used to categorize patents according to their subject matter, and can be a useful tool for conducting a patent search. By using the appropriate classification codes for your field of interest, you can more effectively target your search and find relevant patents. IPC and CPC classifications are standard International and Coperative patent classisfication systems.
- Consider foreign language resources: If you are conducting a patent search in a field that is heavily influenced by non-English-speaking countries, it may be helpful to consider searching for patents and published literature in other languages. While many online patent databases offer the option to search in multiple languages, it may also be helpful to use specialized resources such as translation services or language-specific search tools.
- Use patent mapping tools: Patent mapping tools are software programs that allow you to visualize the relationships between different patents and published literatures related to a particular technology or in a typical time-period. By creating a patent map, you can more easily identify trends and patterns within a particular field, and can use this information to formulate your business strategy.
- Work with a patent professional: While it is possible to conduct a patent search on your own, it is advisable to work with a patent professional who has experience in patent searching. Patent professionals can help you to conduct a more thorough and effective search, and can provide valuable insights and guidance on how to interpret the search results.
In conclusion, advanced patent search strategies can help you to conduct a more thorough and effective patent search, and can provide valuable insights into the state of the art in your field. By utilizing a variety of search tools and resources, utilizing advanced search techniques, considering non-patent literature, using patent classification codes, considering foreign language resources, using patent mapping tools, and working with a patent professional, you can increase the chances of finding relevant patents and published literature and make informed decisions about your intellectual property.
