Every year, excitement abounds around the next big thing in technology. Once upon a time, long, long ago – if we’re measuring in tech years – it was about flash drives and touchscreens. More recently, 3D printing and gene editing were hot topics. In the last couple years, crypto and the metaverse captured imaginations. As hot new technologies emerge – like language model ChatGPT, which converses in a human way – there is always plenty of hype, and we have to ask, Is this technology really a hotbed for innovation or a bunch of hot air? One way to suss out that question: patent applications. Numbers tell a story, and when companies are allocating capital to publicly protect their inventions, then they’re probably on to something important that will have long-term implications for their business, for consumers, and ultimately for society.
Each year, IFI CLAIMS, the industry’s most trusted patent data provider, reviews the thousands of US patent applications that are filed, along with their classes and sub-classes, to determine the year’s fastest growing technologies. Applications, we should note, are a better proxy than grants, because they’re an indication of what is novel now. Grants are more of a lagging indicator because it takes an average of 18 months between a patent application and an actual grant of rights. See below for IFI’s Top 10 Fastest Growing Technologies for 2022, along with charts that show aggregate patent application statistics.

10. Breathing Masks
CPC Code: A62B 18
Unsafe and foul air has long had humanity waiting to inhale, so breathing masks have a storied past. Fun fact: painter and scientist Leonardo da Vinci recommended a wet cloth over the nose and mouth as a protective barrier against harmful air. Respirator technology made big strides in the US during the early 1900s, in the wake of legislation aimed at protecting miners against poisonous and particulate-filled air (miners previously used canaries to ascertain whether carbon monoxide was present). Breathing masks have protected against chemical warfare, fire hazards, and debris-filled air, as we saw in the aftermath of 9/11.
Breathing mask patent applications have risen at a rate of 25% over the past five years, but notably, most of the growth occurred in the last two years, 168% during the COVID-19 pandemic, presumably as researchers looked for more effective ways to protect essential healthcare workers with PPE, including respirators.
Growth of Breathing Masks
3M Holds Breath
3M, the $35 billion consumer goods, healthcare and worker safety company was front and center during the coronavirus pandemic as the company scrambled to provide N95 masks, and other personal protective equipment, to essential workers. 3M applied for the most patents last year for breathing masks, which protect against hazardous particles entering the respiratory system. In addition to healthcare workers, 3M’s respiratory masks protect workers in other industries, including automotive, construction, and manufacturing.

Will machines take over the world? It’s an enthralling question when considered from the perspective of science fiction. But as a category under the umbrella of artificial intelligence, machine learning (ML) is the use of mathematical systems and specific data sets to mimic ways that humans learn, with ever-improving outcomes and predictions over time.
Since 2018, year-over-year development in ML applications has been robust, showing a 26% growth rate. Even with all the progress in this technology, no machine, no matter how intelligent, will ever totally replace the complexity, intuition, and nuance of human conclusions.
Growth of Machine Learning
IBM Reigns Supreme on Machine
With more than 6,000 ML applications over the past five years, IBM is head-and-shoulders above Microsoft, Google, and Samsung. Making inroads into this technology is clearly a priority for Big Blue, which lays claim to a deep history in the arena. In fact, IBMer Arthur Samuel is credited with popularizing the term “machine learning” with his work around the game of checkers and a self-learning checkers computer that beat a human grand master in 1962. Some examples of machine learning from everyday life today? Commuting time predictions on GPS systems and Netflix’s movie recommendations.

4. Computing Arrangements Based on Biological Models
CPC Code: G06N 3
Understanding the science of life, from the molecular level to an entire organism (and the systems that support it), requires a staggering amount of data and research. So using computational power to study biological prototypes bodes well for advancements in the fields of medicine, ecology, botany, marine biology, microbiology, and virology, among others. Scientists can create a virtual heart, for instance, in order to predict the progression of cardiovascular disease. The spread of infectious diseases, such as COVID-19, can be mapped, with effects of vaccination forecasted. Actual biologic tissue – DNA, for instance – can be employed in the computer modeling.
Propagating Computing Capabilities for Biology
Over the past five years, the G06N 3 subclass has sprouted nicely at an annual rate of 32%. But the growth has let up from the previous year’s rate of 55%. Perhaps it’s just a developmental stage in the biological computing lifecycle?
Growth of Computer Systems Based on Biological Models
Biological Supercomputing Innovators
Big Blue is at the forefront of this class with more than 5,500 patent applications. One of the class’s key technologies is deep learning, and a particular form of it called convolutional neural networks, which helps machines see and interpret images, for instance, as humans do.

3. Special Features Related to Earth Drilling for Obtaining Oil, Gas, or Water
CPC Code: E21B 2200
For all the debate about how soon we achieve the goal of net zero greenhouse gas, fossil fuels could be providing energy for many more decades to come. Which means earth drilling technologies, such as the horizontal drilling that furthered the progress of hydraulic fracking, will continue to advance – or at least become more efficient and better able to optimize the quantities of fuel extracted from the ground.
Overall, earth drilling technologies have decreased by 13% in the past year. But when it comes to special features related to oil, gas, and water drilling, the technology is up by a compound annual rate of 33%. Special features can be anything from chokes and valves for regulating flow to the use of computer simulations and machine learning.

1. Autonomous Vehicles
CPC Code: B60W 60
While the technology behind autonomous vehicles keeps accelerating, self-driving cars are much further down the road when it comes to widespread use – or even minimal use outside of sunny Arizona. Creating an automobile that performs like a human in all driving conditions requires R&D well beyond where it currently stands. AVs, we’re told, are the big, bright, exciting future. But will the future ever be now? Hey Toyota, Waymo, are we there yet? And, until that future arrives, how much longer can companies keep investing big bucks in the tech before they have to hit the brakes?
Autonomous Can’t Drive 55
For now at least, technology for autonomous vehicle drive control systems is in the fast lane with a CAGR of 64%, hurtling into the number one fastest growing technology spot. Last year, it didn’t even crack the top 10.
Growth of Autonomous Vehicles
Toyota in the Pole Position
Japanese automaker Toyota applied for the most patents in self-navigating vehicle technology in 2022. Despite that, executives expressed public skepticism last year about how long it will take before fully autonomous vehicles will be ready for the road. The company minces words when it comes to the concept of self-driving cars. Toyota uses the word “automated” referring to technology that augments human command of the vehicle and “autonomous” only when a system can take the place of the driver for a certain period of time.
