Using Patexia's Patent Search Tools

Video Guides

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

Getting Started​

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.

 

 

 

 

Search Visualization

 

Turn the visualization option on to graphically observe the search results and density of patent filings. 
 
You can control the X-Axis of the visualization using the drop down menu at the bottom right of the graph. If you switch between filing or issue dates, the left column of the search results will also reflect your selection (i.e., switch between filing or issue dates accordingly).
 

 

Other Search Criteria

 

Clicking on Add Criteria will show you a drop-down menu where you can select other criteria: assignee, inventor, agent, country, and IPC (International Patent Classification)--for more information on the definition of these terms, check out our glossary. By adding more criteria to your search, the results will include all documents that have that fit those criteria. For example, if you use the keyword “system,” use “Intel” for the assignee, and use “United States” for the country,the results will include only United States issued or published patents that have been assigned to “Intel” and contain the keyword “system”somewhere in the abstract, body or claims of the patent.

 

 

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:

 
 
As you can see, the filing activity has increased substantially in recent years. If you want to look at a particular period, you can zoom in by clicking and dragging your mouse over that period.

 

 

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.
