Reusable rockets, air taxis and ‘autonomous autos’ are the future: WIPO

This article is published in association with United Nations.

Air taxis, “autonomous autos” and reusable rockets are just some of the future transport solutions that inventors all over the world are striving to make a reality, while patents for combustion engines are “flatlining”, the UN intellectual property agency (WIPO) said on Thursday.

Latest information gleaned from patent filings featuring in WIPO’s Technology Trends report on the Future of Transportation, offers a tempting glimpse of a not-so distant and enticing future where there’s less traffic pollution, fewer snarl-ups and air travel to the other side of the world – made possible in just a few hours.

“Analysis of patents shows that inventors are working hard to ensure that how we get around tomorrow is cleaner and better than today,” maintained WIPO, which said that patent filings for future transportation solutions have grown by 700 per cent over the last two decades, from 15,000 inventions in 2003 to 120,000 in 2023.

“Autonomous ships and smart ports are revolutionizing transportation at sea; electric vehicles, high-speed trains and smart traffic management systems are driving change on land,” WIPO insisted.

“Vertical take-off and landing aircraft are offering new ways to travel by air, while reusable rockets and satellite technology are pushing what is possible beyond the earth’s atmosphere.”

Driving this trend is the recognition that transportation accounts for more than one-third of CO2 emissions globally, which has encouraged the development of sustainable technologies that reduce the environmental impact of transportation.

These include the adoption of electrified propulsion, the shift to renewable energy sources and the promotion of public and shared transport options.

Digitalization is also revolutionizing the transportation sector, WIPO insists, pointing to the rise of autonomous driving, “which is projected to generate from $300 billion to $400 billion in revenue by 2035”.

Patently true

According to the Geneva-based UN agency, intellectual property supports this kind of groundbreaking innovation – such as wireless charging for electric vehicles – by encouraging investment in research and development.

Competition is fierce as firms jostle for access to rare earth minerals, while AI is also taking centre stage, WIPO says.

“The report also shows flatlining growth in patenting activity for legacy products like the internal combustion engine and other fossil fuel-based systems” such as catalytic converters, the UN agency noted.

Its data indicated that more than 1.1 million inventions have reshaped transportation since 2000, introducing the prospect of sustainable alternatives to fossil fuel-based systems such as renewable energy cells, air taxis and self-piloting cargo ships.

In the driver’s seat of this travel transformation are China, Japan, the US, South Korea and Germany, which represent the world’s top inventors. Land transportation patents dominate global filings, at 3.5 times more than for air, sea and space combined. The US, meanwhile, has filed the most international patents.

The largest area of growth in patenting is related to sustainable propulsion – such as batteries for electric vehicles or hydrogen fuel cells – which represent efforts to ensure that people and goods are moved around in a “cleaner, more climate-friendly fashion”.

Experts with an eye on imaginative transport solutions for the future say that AI is also poised to play a key role. They point to the rise of autonomous driving, although infrastructure has not adapted swiftly enough for such vehicles to take over, the WIPO report notes.

Drone dilemma

The scarcity of minerals, meanwhile, will determine whether the world can massively adopt electric cars – vehicles that report co-author Christopher Harrison says may not be miracle solutions for private owners.

“Having these rare and limited raw earth minerals in an electric vehicle for personal use that’s been utilized only a few per cent of the day is not an effective use of those tools,” he told journalists.

In the air sector, drones will continue their sky-high ascension.

“I would not like to look up at a sky full of drones delivering pizzas or a pair of gloves to my house and causing visual and noise pollution,” said Robert Garbett, the founder of Drone Major Group, cited in the WIPO report.

“If a delivery is to a remote location that is really hard to get to, people will be more likely to accept it as a beneficial solution,” he added, citing emergency medicine as an example.

According to WIPO, transport patent growth in China has been strong given its recent dominance of the electric vehicle market. But other countries have also contributed with strong patent filings activity including Sweden, Italy, India and Canada.
