Patent searching is an essential step for inventors and patent professionals to determine the novelty and non-obviousness of their inventions, as well as to avoid potential infringement issues. Patent searching tools can help streamline the process of searching and analyzing existing patents, making it easier to identify relevant prior art and assess the potential patentability of an invention. In this article, we will provide a comprehensive guide to patent searching tools for inventors and patent professionals.
I. Types of Patent Searching Tools
There are several types of patent searching tools available, ranging from free online databases to more advanced software tools. The most commonly used patent searching tools include:
- Free Online Databases: There are several free online databases available that allow users to search for patents, including the US Patent and Trademark Office (USPTO) database, the European Patent Office (EPO) database, and the World Intellectual Property Organization (WIPO) database. These databases are accessible to anyone with an internet connection and provide basic search functionalities to search for patents based on keywords, inventors, assignees, and classifications.
- Commercial Patent Databases: There are also several commercial patent databases available that provide more advanced search functionalities and features, including patent analytics and visualization tools. Examples of commercial patent databases include PatBase, Derwent Innovation, and LexisNexis Patent Advisor.
- Patent Search Software: Patent search software tools provide advanced search functionalities and features, including semantic searching and artificial intelligence algorithms. Examples of patent search software tools include PatSnap, Innography, and Questel Orbit.
II. Key Features and Functionalities
The key features and functionalities of patent searching tools vary depending on the tool and the provider. However, some of the most common features and functionalities include:
- Keyword Searching: Keyword searching allows users to search for patents based on specific keywords or phrases related to their invention. This is the most basic form of patent searching and is available on all patent searching tools.
- Boolean Searching: Boolean searching allows users to combine multiple search terms and operators (e.g., AND, OR, NOT) to refine their search results and find more relevant patents.
- Advanced Filters: Advanced filters allow users to refine their search results based on specific criteria, such as the patent application date, the inventors, the assignees, and the patent classifications.
- Citation Searching: Citation searching allows users to search for patents that have cited a specific patent or patent application, which can help identify relevant prior art.
- Analytics and Visualization Tools: Some patent searching tools provide analytics and visualization tools that allow users to analyze and visualize patent data, including patent trends, patent citations, and patent family trees.
III. Best Practices for Patent Searching
While patent searching tools can be powerful tools for inventors and patent professionals, it’s essential to follow best practices to ensure that the search results are accurate and comprehensive. Some best practices for patent searching include:
- Start with a broad search: Start with a broad search using general keywords related to the invention. This will help identify relevant patents and narrow down the search criteria.
- Use Boolean operators: Use Boolean operators to refine the search criteria and exclude irrelevant patents from the search results.
- Check the patent classifications: Check the patent classifications to ensure that the search results are relevant and comprehensive.
- Review the patent claims: Review the patent claims to determine the scope of the patent and identify potential infringement issues.
- Search beyond patents: Search beyond patents to identify relevant prior art, including scientific journals, conference proceedings, and industry publications.
Patent searching tools can help inventors and patent professionals identify relevant prior art, assess the potential patentability of an invention, and avoid potential infringement issues. The key to successful patent searching is to use the right tool for the job
