We've created some short video guides that you might find useful for conducting your searches. You can also read about how to use the Patexia tools in much more detail below.
Using the Patexia Patent Search Tool
Patexia’s patent search is quite simple. Start by typing a patent number or any other keyword in the search box that appears at the top of every page on the site. Make sure you’ve selected “patent” as your search option.
You will then be directed to the IP Research page. On this page, you can click on patent results to see more details about a particular patent or patent application. Also, you can refine the patent results or use the visualization tool to analyze the information.
Refining Search Results
On the IP Research page, you can use the search tools to refine your results--you can add more keywords or change the range of the issue or filing date.
Note: The patent results will change automatically as you type new keywords or other search criteria.
Other Search Criteria
Most fields have an auto-complete feature which will suggest search terms as you type. You can also provide multiple names or keywords, separated by commas. However, if multiple assignees or inventors are selected, the results will be shown separately and not combined. For example, if you select “Intel” and “Sony” as assignees, you will see all the patents assigned to either Sony OR Intel.
Finding Industry Trends
If you are interested in researching trends for a particular invention or area, you can easily use the search criteria to observe the activity for that particular field. For example, searching the US patent database for the word “biomarker” returns the following result:
Clicking on Reset zoom will return to the original graph. Also hovering over the graph will show details about that point in time. Clicking on any point will automatically narrow down the date range and show the results for that period:
The plot will automatically disappear or change to a bar chart if the results include only a small number of patents or patent applications.
Comparing Company Portfolios
It is very simple to compare the portfolio of two or more companies, people, etc. Simply select the right criteria (e.g., Assignee) and type in the appropriate names separated by commas:
Similarly, we can use the Country criterion to observe the filing activity by the assignee’s country. For example, this graph shows the results for USA and Japan for Sony, Intel and Cisco for the given period:
Clicking on a field in the legend will turn that particular field on or off.
Clicking on any of the bars in the graph will narrow down the results to that bar (date range) and turn the visualization off automatically if it is only a single day.
