The automotive industry shook a little yesterday with Tesla announcing that they are making their patents available to its competitors. We analyzed about 249 of Tesla’s patents & here is what we found overall. (Update. We also did a follow up analysis on Tesla's patents to reduce battery fires which makes cars safer, lowers insurance costs & reduces the total cost of ownership of electric cars)
The categorization of these patents is an estimate based on analyzing Tesla's patent keywords, reading the abstract and sometimes even diving into the patent to categorize it. Our research & analysis includes patents & lawsuits so our automotive & patent research experience helped us dive into this much faster.
We have categorized about 184 patents & the battery & charging systems seem to have the most amount of patents at 104 & 28 respectively. Based on our estimates, 65 patents of the 249 patents do not fit into these buckets & seem to be very specific. For e.g. There is a patent related to a vehicle’s suspension called the “Vehicle air suspension control system”. We will continue to analyze further & group some of these patents into smaller categories if it makes sense. We will update this post if anything changes.
Some examples of patents & categorizations are below:
Electric vehicle extended range hybrid battery pack system
Charge rate optimization
Method of operating a dual motor drive and control system for an electric vehicle
User configurable vehicle user interface
Sunroof positioning and timing elements
Method of controlling a dual hinged vehicle door
Cooling & Coolant Systems
Passive air bleed for improved cooling systems
Automated audio optimization system
