The AIr™ Patent
AIr™ is built upon a globally granted method patent (Priority Date: July 5, 2014) that protects the core process of transforming drones into autonomous cleaning tools using airflow. The patent secures the intellectual property for using sensor-based alignment to clean surfaces without physical contact, water, or chemicals.
Intellectual Property
The foundational claim of the patent reads:
“Method for controlling a flying body for cleaning surfaces, comprising a sensor system for the detection of geometrical characteristics of an object and the alignment of a flying body according to said object in order to clean it using the airflow of said flying body.”
This claim defines a process where drones equipped with sensors to autonomously detect and align themselves with surfaces to clean them with their own airflow. The method enables precision cleaning while avoiding physical contact.
AIr™ Applied
This claim protects the precise sequence required to turn an aerial vehicle into an embodied AI cleaning agent:
- Sensor-Based Surface Detection: Using downward-facing sensors (optical flow, LiDAR, ultrasonic, or computer vision) to read surface geometry.
- Autonomous Alignment: The flight controller processing that data to align the drone at the optimal altitude and orientation.
- Airflow Cleaning: Utilizing the drone’s generated rotor downwash to systematically remove dust or debris.
Validation & Prior Art
When this patent was filed in 2014, drones rarely featured the sensor systems required for precise autonomous alignment, making the method highly novel. The foundational nature of this IP was further validated when a similar main patent claim (EP3183170), subsequently filed by a team of eight inventors from a major Silicon Valley technology company, was withdrawn following third-party observations citing the AIr™ priority.
Scope of Protection

Commercial Scope & Licensing FAQ
Disclaimer: This section addresses common commercial questions and legal constellations regarding the AIr™ patent portfolio. It is informational only and does not constitute legal advice. For specific inquiries regarding potential infringement or licensing, please consult a qualified IP attorney.
What if someone claims they’re simply inspecting surfaces and not cleaning them — could this incidentally infringe the patent?
Inspection typically differs from cleaning in altitude, sensor usage precision, airflow direction/intensity, and intervals. However, if inspection involves close alignment and airflow sufficient to remove debris—even unintentionally—this may constitute infringement where the patent is valid. Genuine inspections at higher altitudes without intentional debris removal generally do not infringe.
What is indirect infringement, and how could it apply here?
Indirect infringement occurs when someone induces or contributes to another party’s infringement. For example, providing software, flight plans, or instructions enabling others to practice the patented airflow cleaning method commercially in protected jurisdictions could constitute indirect infringement — even if the provider does not directly operate the drones themselves. Without a license, cross-border collaboration must be carefully managed to avoid legal exposure for indirect or contributory infringement.
Can the patent be easily circumvented, and if so, how?
Patents protect specific methods described in their claims. To legally circumvent this patent, an alternative solution would need to avoid at least one essential element of the core claim — for example, by not using drone-generated airflow or by not aligning autonomously based on geometrical characteristics detected by sensors. Practically speaking, circumventing this patent would require adopting significantly less efficient or fundamentally different cleaning methods.
How does this patent apply to water spraying drones?
If drone-generated airflow actively contributes to debris removal alongside or after water application (e.g., drying or clearing residual debris), it may fall under the scope of protection in jurisdictions where granted. Purely water-based cleaning without significant airflow involvement generally does not infringe.
Does extraterritorial infringement apply on method patents?
Generally speaking, methods are performed within specific jurisdictions. However indirect/contributory infringement can occur if components (software/hardware enabling autonomous alignment) are manufactured abroad specifically intended for use within protected territories — once imported/utilized there commercially they may indirectly infringe upon method patents.
What could constitute patent infringement?
Patent infringement occurs when someone makes, uses, sells, offers for sale — or imports into protected jurisdictions — a product or method containing all essential elements described in at least one granted claim. Infringement can be direct (performing yourself), indirect (enabling others), or contributory (supplying components specifically intended for use in infringement).
Are there other common forms of infringement?
Yes — willful infringement involves knowingly using patented technology without authorization despite awareness of its existence; induced infringement involves actively encouraging/facilitating another’s infringement. Both can result in enhanced damages if proven legally.
Can I legally use patented technology for research purposes without permission?
Some jurisdictions permit limited exceptions for purely academic research without commercial intent; however any commercial use — including research aimed at commercialization — typically requires explicit licensing permission from the holder.
How could subroutines in today’s flight controllers be implicated?
Modern flight controllers often include subroutines continuously aligning drones toward surfaces using sensor data fused with altitude control/stabilization features. If these subroutines autonomously align drones based on surface geometry before using airflow for cleaning purposes commercially without licensing — this directly infringes upon essential elements described within claims where validly granted patents exist.
Can manually controlled drones circumvent the patent?
Manual control alone does not guarantee circumvention. Most modern drones — even when manually operated — use built-in flight controller subroutines (such as altitude hold or optical flow stabilization) that autonomously align drones relative to surfaces using sensor data. If these subroutines are used in combination with airflow cleaning, this may still infringe upon essential elements of the patented method in jurisdictions where it is valid.
Isn’t using drone airflow for cleaning too obvious or trivial to patent?
Drone airflow cleaning was not considered obvious when the patent was filed in 2014. At the time, drones rarely featured sensor systems capable of precise autonomous alignment. The patent specifically protects the innovative combination of sensor-based autonomous alignment and airflow cleaning — a method that had not been previously described or anticipated. The independent granting (and subsequent withdrawal after third-party observations) of a similar main patent claim in EP3183170, filed by eight inventors from Silicon Valley, further highlights its novelty and non-obviousness.
