Houston leads the charge for patents in the South. Photo via Getty Images

A study analyzing top U.S. locales for the tech industry ranked Houston the No. 9 best tech hub in the South.

The report by commercial real estate platform CommercialCafe examined the top 20 Southern metros across nine metrics, such as the growth rates of tech establishments and employment, median tech earnings, a quality of life index, and more.

Like other Texas metros, the study attributes Houston's tech powerhouse status to its growing presence of major tech companies. However, Houston leads the nation with the highest number of patents granted between 2020 and 2024.

"The second-largest metro by population in the South, Houston led the region with an impressive 8,691 tech patent grants in the last five years," the report said. "Once synonymous with oil, Houston is increasingly making its mark as a cleantech hub — and patents reflect this shift."

Houston also experienced an impressive 14 percent growth in tech establishments, with nearly 500 new tech companies moving to the metro. An impressive 32 percent job growth rate also accompanied this change, with over 30,500 tech jobs added between 2019 and 2023.

Here's how Houston stacked up across the remaining five rankings:
  • No. 11 – Tech establishment density
  • No. 15 – Median tech earnings
  • No. 19 – Median tech earnings growth
  • No. 20 – Tech job density
  • No. 20 – Quality of life index

In a separate 2024 report, Houston was the No. 22 best tech city nationwide, showing that the city is certainly making efforts to improve its friendliness toward the tech industry in 2025.

Other top Texas tech hubs in the South
The only other Texas metros to earn spots in the report were Austin (No. 1) and Dallas-Fort Worth (No. 4). Most notably, CommercialCafe says Austin saw a 25 percent increase in tech company density from 2019 to 2023, which is the third-highest growth rate out of all 20 metros.

"Moreover, the metro’s tech scene thrives on a diverse range of segments, including AI and green energy (bolstered by the University of Texas), as well as globally recognized events like [South by Southwest]," the report says. "Thus, with tech companies accounting for more than half of all office leasing activity in 2024, Austin remains a magnet for innovation, talent and investment."

Dallas, on the other hand, has a far greater diversity when it comes to its tech sector and its thriving economic opportunities.

"Not to be outdone, Dallas-Fort Worth moved up from sixth to fourth in this year’s rankings, driven by a 25.9 percent growth in tech company presence — the second-highest increase among the top 20 metros," the report said. "For instance, companies like iRely (which relocated to Irving, Texas) and Diversified (now in Plano, Texas) have joined homegrown successes, such as StackPath and Bestow."

The top 10 best tech metros in the South are:

  • No. 1 – Washington, D.C.
  • No. 2 – Austin, Texas
  • No. 3 – Raleigh, North Carolina
  • No. 4 – Dallas-Fort Worth, Texas
  • No. 5 – Huntsville, Alabama
  • No. 6 – Baltimore, Maryland
  • No. 7 – Durham, North Carolina
  • No. 8 – Atlanta, Georgia
  • No. 9 – Houston, Texas
  • No. 10 – Charlotte, North Carolina

2 Houston universities score big for patents, MBA programs

academic standouts

Two new rankings have put the University of Houston and Rice University in the academic limelight.

UH ranks 60th on the National Academy of Inventors’ list of the top 100 universities for utility patents granted last year in the U.S. Meanwhile, Rice has moved up dramatically on Bloomberg Businessweek’s annual list of the top full-time MBA programs.

In 2022, UH received 32 utility patents. The university explains that utility patents are among the world’s most valuable assets because they give inventors exclusive commercial rights for producing and using their technology.

UH joins the University of Texas (No. 3), Texas A&M University (No. 37), Texas Tech University (tie for No. 75), and Baylor University (tie for No. 75) as the only Texas schools on the patent list.

“This recognition further underscores our commitment to innovation and the impactful research taking place at UH,” says Ramanan Krishnamoorti, the university’s vice president of energy and innovation. “It is a testament to the dedication and ingenuity of our faculty, researchers, and students who continue to push the boundaries of knowledge and drive positive change in our world through their hard work and inventive contributions.”

Rice also is sharing in recent academic accolades.

Rice’s Jones Graduate School of Business climbed 10 spots — to No. 19 — in Bloomberg Businessweek’s 2023-24 ranking of full-time MBA programs. Rice holds the No. 1 spot among Texas programs.

The Jones School gained ground in the ranking’s learning, networking, diversity, and entrepreneurship categories.

“Rising in the rankings for networking and diversity shows how Rice’s faculty and staff are dedicated to creating an entire environment and ecosystem that benefits our students, not just what happens inside the classroom,” says Peter Rodriguez, the business dean at Rice. “I am especially proud of these metrics that highlight Rice’s ability to bring people together.”

How patents can provide additional revenue streams for Houston innovators

GUEST COLUMN

Seeking patent protection can offer a substantial competitive advantage to startups looking to raise capital, especially during a venture capital downturn. Besides the protection patents can provide against intellectual property theft, they are also assets that can translate into expansion opportunities and additional revenue streams. These factors are important to institutions and individuals that invest in startups, as they may reduce downside risks to their investments and help outline a growth trajectory.

As Kathi Vidal, under secretary of commerce for intellectual property and director of the U.S. Patent and Trademark Office, said during a speech last year, “having a [patent] pending application helps secure funding, and it keeps potential competitors out of your space.”

The experience of Austin-based VoChill, a startup that created a new line of personal wine chillers, offers a case study of how filing for patent protection as early as possible can set up any startup for success, not only when seeking to raise capital, but also when working to expand its commercial relationships and distribution channels.

Filing for patents quickly gave VoChill’s founders a competitive advantage when approaching potential investors, as it demonstrated the management team’s high level of preparedness and business acumen. For investors who eventually committed capital to the startup, the filings signaled a safer bet on investing in VoChill.

There is plenty of evidence indicating that patents help attract capital and generate growth opportunities. A study conducted by professors from Harvard Business School and New York University’s Stern School of Business found that patent protection increased startups’ odds of receiving venture capital funding by 59 percent.

PitchBook data shows that startups seeking patents raise more capital than their non-patent-seeking peers. About 58 percent of venture capital went to startups with patents or with patent applications from 2011 to 2020, the research firm notes.

Patents can also help drive a startup’s expansion and grow sales. According to the National Bureau of Economic Research, or NBER, the approval of a startup’s first patent application increases its employee growth by 36 percent over the following five years. After five years, a new company with a patent increases its sales by a cumulative 80 percent more than companies that do not have a patent.

Patents can also increase a startup’s chances of obtaining distribution deals or, in the case of consumer products, partnerships with retailers. In VoChill’s experience, patent protection is a recurring theme in conversations not only with investors but also distributors and retailers.

Patents offer startups the possibility to pursue a licensing model as well. Licensing or selling the rights to a patent so that others may produce products or processes based on that patent can bring in ongoing revenue streams.

Down the line, having patent protection can lead to better exit opportunities, be it by going public or via a private divestiture.

According to the NBER, having patents more than doubles the probability that a startup is eventually listed on a stock exchange.

PitchBook data, meanwhile, shows that patent-seeking companies go public at a rate more than five times higher than non-patent-seeking companies (23.2 percent versus 4 percent).

In the case of exits via a sale of the startup, the median exit value for patent-holding companies is 154.9 percent higher than it is for companies without patents per year on average, according to PitchBook.

While the business case for seeking patent protection is clear, startups should keep a few considerations in mind when seeking to do so. Understanding time bars is crucial; for example, the United States generally allows only one year to file a patent application after an invention is publicly written about, shown, used, or otherwise disclosed, and overseas often no one-year “grace period exists.”

Still, other important predicates are finding out whether the innovation is truly new, identifying the most crucial components of a product or system, and thinking about what aspects competitors are likely to discover and copy.

A new ranking looks at the Houston companies with the most patents granted in 2022. Photo via Getty Images

These are the Houston companies with the most patents granted last year

by the numbers

Two major players in Houston’s energy industry are also major players in the patent arena.

A new ranking from the analytics arm of patent law firm Harrity & Harrity puts Saudi Aramco, whose North American headquarters is in Houston, and Halliburton, whose global headquarters is in Houston, puts them in a tie for the number of U.S. patents with 963 patents received in 2022. Saudi Aramco and Halliburton now share the title of Houston’s patent king.

Saudi Aramco saw a 12 percent rise in patents granted in 2022 compared with 2021, according to Harrity & Harrity’s Patent 300 report, while Halliburton experienced a 5 percent jump. Each company tied for 44th place among the top 300 U.S. patient recipients in 2022.

According to the report, Samsung Electronics (8,513 patents) knocked IBM off its longtime pedestal as the No. 1 recipient of U.S. patents. IBM (4,743 patents) now holds the No. 2 position.

Many of Aramco’s U.S. patents come from its R&D centers in Houston, Boston, and Detroit. The Houston R&D hub opened in 2014 and underwent an expansion three years later.

Aramco, a Saudi Arabia-based supplier of oil and natural gas, also generates patents through academic partnerships, such as the one it established last year with Rice University’s Carbon Hub. Aramco has committed $10 million over five years to the carbon initiative.

“While patents are a leading indicator of innovation, the ultimate goal is to create value through the development of solutions that help to address a particular need,” Aramco says. “Such results are often only possible with significant upfront investments, and patents make it possible to recoup these costs and potentially generate additional revenue through commercialization.”

Last year, Aramco boasted that it ranked first in the oil and gas industry for U.S. patents (864) granted in 2021. Until 2011, Aramco had received only 100 U.S. patents over a 78-year span.

“Many of the patents are for innovations Aramco uses itself for competitive advantage, although they can also be licensed to others, creating extra value for the company,” Jamil Bagawi, then the company’s chief engineer, wrote in 2021.

Halliburton also has ramped up its patenting efforts in recent years.

According to Houston law firm Yetter Coleman, those efforts kicked into high gear after Halliburton lost a fracking patent lawsuit to Tomball-based BJ Services, which is now out of business. In 2003, a Houston jury awarded $98 million in damages to BJ in the case, and Halliburton had to stop selling the system that allegedly infringed on BJ’s patent.

In the five years before the verdict, Halliburton averaged 142 patent awards a year, according to Yetter Coleman. The law firm reported in 2013 that Halliburton subsequently averaged 234 patents a year.

Today, of course, Halliburton has far exceeded those numbers. And it vigorously defends its growing patent portfolio. In September 2022, for instance, three subsidiaries of the oilfield services giant filed two lawsuits against Houston-based rival U.S. Well Services alleging infringement of 14 Halliburton patents.

IAM, a website that reports about the intellectual property industry, noted that when Halliburton sued U.S. Well Services, “IP professionals in the oil and gas industry may well have reached for the popcorn. Battles of this magnitude rarely break out in their slice of the patent world.”

Halliburton and Aramco may be the goliaths in Houston’s patent world, but they’re not the only local organizations to appear on the Patent 300 list for 2022. Other Houston-area companies that made the cut are:

  • Spring-based Hewlett Packard Enterprise, No. 84. The tech company received 511 U.S. patents in 2022, down 4 percent from the previous year.
  • Houston-based SLB (Schlumberger), No. 117. The oilfield services company received 372 U.S. patents in 2022, down 14 percent from the previous year.
  • Houston-based Baker Hughes, No. 123. The oilfield services company received 350 U.S. patents in 2022, down 11 percent from the previous year.
  • ExxonMobil, No. 156. The oil and gas company received 281 U.S. patents in 2022, down 8 percent from the previous year. It is in the process of moving its headquarters from Irving to Spring.
  • United Imaging Healthcare, No. 253. The Chinese healthcare equipment company, whose North American headquarters is in Houston, received 175 U.S. patents in 2022, up 31 percent from the previous year.

Houston university claims spot on top 100 institutions for patents

UH ranked

The University of Houston ranks among the world's top invention factories.

A new list from the Intellectual Property Owners Association and the National Academy of Inventors puts UH in a tie for 79th place among the 100 universities around the world that received the most U.S. utility patents in 2020. UH inventors earned 37 utility patents last year.

The only other Texas schools on the list are the University of Texas at Austin (ranked fourth with 207 patents) and Texas A&M University in College Station (tied for 70th place with 41 patents). The University of California leads the list (597 patents).

UH has ranked among the world's top 100 patent-receiving universities for the past six years. Utility patents cover new or improved processes, products, or machines. During the federal government's 2020 budget year, the U.S. Patent and Trademark Office granted 360,784 utility patents. They're the most common kinds of patents in the U.S.

"The University of Houston is making critical contributions to science and engineering and hence to society, driven by our overarching goal to improve the quality of life. This ranking reflects our dedication to addressing the most pressing problems faced by society, including energy technology and medical care," Amr Elnashai, vice president and vice chancellor for research and technology transfer at UH, says in a news release.

Another testament to UH's patent prowess: Three researchers from the Cullen College of Engineering researchers are senior members of the National Academy of Investors for 2021. They are professors Hien Nguyen, Jeffrey Rimer, and Gangbing Song.

"Being affiliated with this prestigious organization will afford new opportunities for innovation and expanded research activities by engaging with a global network of highly accomplished inventors," Rimer says.

UH says a key to its success in moving technology from the lab to the marketplace is the UH Technology Bridge. With 30,000 square feet of incubator space and over 700,000 square feet of space for laboratories, pilot-scale facilities, and light manufacturing, the Technology Bridge houses 28 startups.

Plans for the Technology Bridge include expanding the 75-acre park into core districts, along with adding build-to-suit facilities. About 35 acres of the Bridge have been developed. So far, the university has invested more than $75 million in the Bridge.

"Companies taking products from idea to commercialization need expertise ranging from research to licensing to startup formation and operation," Elnashai said of the Bridge. "They need interns in specialized fields, technical and startup consultants, and they often need laboratories with large amounts of space for experimentation, to produce a prototype or to scale their operations. We have all of this to offer."

Venus Aerospace closes $91M funding round to scale hypersonic engine

flight funding

Houston-based Venus Aerospace has closed a $91 million Series B round and plans to scale the production of its hypersonic engine.

The round was led by Houston-based Mercury Fund with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity and other investors, according to a news release.

The investment comes about a year after Venus completed the first U.S. flight test of its high-thrust rotating detonation rocket engine (RDRE). The engine is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus Aerospace says the latest round of funding will allow it to move the RDRE from demonstration to deployment and meet customer requirements for the near-term defense and space industries. The company says that the reusable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types.

“This financing marks an important step in moving Venus from breakthrough demonstration to scaled capability,” Sassie Duggleby, co-founder and CEO, said in the news release. “Our customers need propulsion systems that go farther, can be produced reliably and are built on supply chains they can trust. We are advancing that capability with American engineering and manufacturing talent to strengthen U.S. defense, expand space access and support the future of high-speed flight.”

Venus Aerospace raised a $20 million Series A in 2022, led by Wyoming-based Prime Movers Lab. At the time, the company said it would put the funding toward three main technologies: a next-generation rocket engine, aircraft shape and leading-edge cooling system.

The company also picked up an investment from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, in November 2025—in addition to funding from other investors over the years.

“Since our initial investment, Venus has progressed very quickly in its technology development," Chris Moran, vice president and general manager of Lockheed Martin Ventures, added in the release. "Our reinvestment in Venus recognizes Venus’ accomplishments to date and focus on speed to manufacture, cost management and reduction of supply chain constraints. Venus is working effectively to position its propulsion system for the production scale required by defense programs.”

"Venus is exactly the kind of company Houston capital should be backing," Blair Garrou, co-founder and managing partner at Mercury Fund, added in the release. "It combines multiple frontier technologies, domestic manufacturing and clear commercial and national security relevance. We believe this team is positioned to lead an important new chapter in defense and space, and we are proud to support a company building breakthrough technology here in Texas."

Venus Aerospace and Houston clean tech startup Vaulted Deep were named to the World Economic Forum's Technology Pioneers community earlier this summer. Read more here.

Intuitive Machines lands $148M as part of NASA Moon Base funding

to the moon

Houston-based Intuitive Machines has been awarded $148.3 million to deliver its Nova-C lander to the moon by 2028. The funding is part of $600 million that NASA recently awarded to three companies as part of the agency’s Moon Base Program.

The contracts aim to support sustained human presence and commercial operations on the Moon. Austin-based Firefly Aerospace was awarded $144.2 million by NASA for one mission and Pittsburgh-based Astrobotic netted $297.9 million for two lunar landings. Intuitive Machine's award is the company's sixth task order under NASA's Commercial Lunar Payload Services (CLPS) program.

“We’re building a proving ground for Moon Base operations,” Ryan Stephan, NASA’s Moon Base acting director of cargo landers, said in a news release. “Accelerating our Moon mission ordering cadence and launch opportunities enable us to move quickly to learn, iterate, and improve.”

Under the latest task order, Intuitie Machines will deliver three scientific and operational payloads to the moon, which include a:

  • Linear Energy Transfer Spectrometer (LETS) radiation monitor to gather critical environmental safety data
  • Advanced stereo cameras to analyze surface-plume interactions (SCALPSS)
  • Laser retroreflector array (LRA) for precise cislunar positioning

The funding breakdown includes a $68.6 million base contract and a $79.7 million performance incentive for Intuitive Machines.

The company says the funding will allow it to create a standardized and repeatable "lunar utility pipeline" for delivering cargo to the moon.

"We are shifting the paradigm from custom aerospace engineering to commercial mass production of lunar infrastructure," Steve Altemus, CEO of Intuitive Machines, said in a separate news release. "Our flight-proven Nova-C platform allows us to build, test, and deploy multiple landers in parallel using Industry 4.0-powered manufacturing. This contract directly advances our core mission to provide persistent, reliable, and commercial baseline of transport, connectivity, and operations that allows our customers to stay longer and achieve more on the Moon."

NASA also shared that it is exploring plans to send PROMISE, a rover based on the Mars Perseverance and Curiosity rovers, to the moon and it plans to seek proposals for additional lunar lander missions, technology demonstrations, a communications and navigation satellite network, and new science payloads to support its lunar outpost. NASA is developing its Moon Base near the lunar South Pole. The agency expects it to come to fruition sometime after 2032.

Intuitive Machines had received its last CLPS award for $180.4 million in March 2026. It will be the first mission to utilize the company's larger cargo lunar lander, Nova-D. The company was also recently awarded a $1 million grant from Maryland Gov. Wes Moore to expand its robotics operations in the state.

UT team develops wearable technology for atmospheric water harvesting

In The Air

Engineers at the University of Texas at Austin have developed a prototype jacket that harvests clean drinking water directly from the atmosphere, and it works even in the driest desert conditions.

The research, published in Science Advances, marks the latest milestone in nearly a decade of work by materials scientist and chair professor Guihua Yu and his team at the Cockrell School of Engineering's Walker Department of Mechanical Engineering and Texas Materials Institute. The wearable technology marks a significant leap: instead of a bulky, stationary machine, this jacket does the work.

"We have been working on atmospheric water harvesting technology for a number of years," Yu says. "This current version is even more wearable. We're transitioning from conventional, more stationary water harvesting to something truly portable and personal."

Yu's lab first published work on hydrogel-based water harvesting around 2019, and the jacket is the latest evolution of that platform, now called AirGel. Last year, the broader AirGel invention won the top prize in the graduate category of the National Collegiate Inventors Competition.

The jacket is woven with specially engineered hydrogel fibers; ultra-porous materials that attract and absorb moisture from the surrounding air much like a household desiccant. Unlike a desiccant, the material doesn't require intense heat to release that water. The hydrogel is thermally responsive, meaning a modest rise in temperature — even from mild solar heating — is enough to release the water it has captured.

Condenser test in AustinSo, somebody would be wearing the jacket, or perhaps carrying this gel-like textile as a blanket, as it passively absorbs moisture from the air. Then they would detach the textile panels and place them into a small, portable collector unit; essentially a compact heater. The water evaporates out of the textile, condenses inside the collector, and drips out as clean, drinkable water.

"It immediately becomes drinkable because it already goes through the distillation process," Yu explains.

In trials, the jacket produced between 400 and 900 milliliters of water per day depending on humidity, or roughly 14-30 ounces, nearly a quart, depending on the air's humidity. With one kilogram of the textile, the researchers found they could generate approximately 3.7-4 liters of water in arid conditions, and potentially double that in humid ones. So far, the team has tried the jacket out in very dry, semi-dry, and humid areas, and the jacket was able to pull water from each climate.

Lead researcher Chuxin Lei, a postdoctoral researcher on Yu's team and co-author on the paper, says the goal was to rethink who this technology could serve.

Portable bag contents

"Many current [atmospheric water harvesting] systems are still built as rigid or stationary platforms, making them less suitable for people who are moving, working outdoors, or operating in some remote environment. This lead us to ask whether we could build a water harvesting system that could become more like clothing — light, wearable, flexible, and naturally suited for personal use," Lei says.

The potential applications are wide-ranging. Yu's team has previously worked with the Department of Defense on water solutions for soldiers, where water logistics can be dangerous and costly. The technology could also serve hikers, emergency responders, disaster relief workers, and agricultural and field workers. Anyone who needs clean water on the go and far from infrastructure.

The team also sees a potential future where the technology complements large-scale centralized water systems rather than replacing them.

"Our solution cannot be a universal solution for all," Yu acknowledges. "But I think it's an extremely important alternative."

For now, the jacket is still a laboratory prototype, but Yu and Lei are optimistic. With the right industry partnerships, they say, the technology could realistically reach commercial scale within three to five years.
