Drone technology has opened the door to fascinating possibilities. Many companies around the world are working to take advantage of such by investing in research and development. As with any investment of this nature, inventions are conceived and patent applications are filed in various patent offices around the world, including the United States Patent and Trademark Office (USPTO). The USPTO provides a veritable treasure trove of data that can be processed to measure innovation and determine who is doing what and when.     

DRONE PATENT GROWTH 

Regarding when, as observed via a recent post, there has been an explosion of issued patents directed to drone technology. To analyze such, we conducted a search of records available via the USPTO to identify issued patents with titles that include the terms “drone,” “unmanned aerial vehicle,” “unmanned aircraft system,” or “UAV.” We refined the results of our search to utility patents (i.e., patents that protect function versus design patents that protect appearance) that had been assigned (e.g., from an inventor to a company). The refined results yielded 349 patents with a rapidly-increasing application and issuance rate, as indicated via the following chart.   

LEADERS IN DRONE PATENTS

Regarding who, we learned that the vast majority of the issued patents are assigned to U.S. companies with companies in France and China tied for second place, as indicated by the following chart.  

Drilling down further with respect to geography, we discovered that the top 5 cities of patent holders for drone technology are Morristown, NJ, San Francisco, Armonk, NY, Chicago, and Shenzhen, China, as indicated by the following chart.

Of the companies, the top 5 patent holders are Honeywell, IBM, DJI (Da-Jiang Innovations), Boeing, and Amazon, as indicated by the following chart.

CLASSES OF DRONE PATENTS

Regarding what, we discovered that the majority of the issued patents were assigned to 1 of 3 classes, i.e., (1) drone machines (generally); (2) systems for controlling/regulating non-electric variables; and (3) measuring distances/levels/bearings, surveying, navigation, gyroscopic instruments, or photogrammetry/videogrammetry.  The following chart provides further details regarding such.

Among the many things that can be gleaned from searching records at the USPTO, it is clear that drone technology is booming with no end in sight. Further, as more patents are issued and the classes become more crowded, it is particularly important to engage competent patent counsel and ensure your technology is properly protected.
