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."

Houston museum showcases America's founding documents in rare exhibit

Experience History

As the United States prepares to celebrate its 250th birthday, Houstonians have a chance to see rare documents from the founding of the nation. Freedom Plane National Tour: Documents That Forged a Nation, presented by the National Archives Foundation, will be on display at the Houston Museum of Natural Science through Monday, May 25.

The collection includes a rare engraving of the original Declaration of Independence; official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton; a draft of the Bill of Rights; the Treaty of Paris, the documented that recognized America's independence from Great Britain; and the tally of votes approving the Constitution.

The National Archives specifically chose Houston as one of only eight cities in the country to host the exhibit as a means to help the documents reach a wider audience outside of the main hub of semiquincentennial events in New England and the Washington, D.C. area.

"One of the things we decided when we put the tour together because we wanted to be off the East Coast," said Patrick Madden, CEO of the National Archives Foundation, who was onsite for the exhibit's opening in Houston. "There's a lot of 250th celebration stuff happening in the original 13 colonies. How do we get it to major markets where larger numbers of people can see it? So in the case of Houston, obviously, [is a] major market in this part of the country, but also we've partnered with the museum twice before with National Archives exhibits, so we knew that they would be up to the task of handling the exhibit and the crowds."

The star of the collection is a rare engraving of the original Declaration of Independence. Secretary of State and future president John Quincy Adams commissioned 200 exact replicas of the document from engraver William J. Stone in 1823. Less than 50 now remain. Madden joyfully pointed out that there are errors in this document, a potent reminder that the men who forged a nation made mistakes.

"There's a couple of typos in it where they had to make corrections," said Madden. "So even the founders, you know, they're all human. That resonates because here these people are making this move against the most powerful nation in the world and putting their lives on the line for a country based on ideas."

Other impressive parts of the collection include official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton, as well as one of the drafts of the Bill of Rights. Many states would not ratify the Constitution until certain rights were included in the document, leading to Washington going on a national tour assuring state leaders enshrining protections was first on the list. The draft copy on display specifically shows the First Amendment in progress.

Houston is the fourth stop on the exhibition's tour, which will take the documents to Denver, Miami, Dearborn, and Seattle through the summer. Freedom Plane is just one part of a larger patriotic celebration at the HMNS, which includes a film series celebrating American science and culture and general Americana decoration throughout the main hall.

Admission to Freedom Plane is free to the public, but separate from general admission to the museum. Space is limited, and passes are available on a first-come, first-serve basis. Non-members should expect long waits or the possibility that the day's passes are sold out. Only museum members can reserve passes for specific times. Flash photography is prohibited due to the fragile nature of the documents.

Houston quantum energy chip startup emerges from stealth with $12M round

seed funding

Houston-based Casimir has emerged from stealth with a $12 million seed round to commercialize its quantum energy chip.

The round was led by Austin-based Scout Ventures. Lavrock Ventures, Cottonwood Technology, Capital Factory, American Deep Tech, and Tim Draper of Draper Associates also participated in the round. The oversubscribed round exceeded the company’s original $8 million target, according to a news release.

Casimir’s semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company plans to commercialize its first-generation MicroSparc chip by 2028.

The MicroSparc chip measures 5 millimeters by 5 millimeters and is designed to produce 1.5 volts at 25 microamps, comparable to a small rechargeable battery, without degradation and no replacement cycle.

“Casimir represents exactly the kind of breakthrough dual-use technology Scout Ventures was built to back,” Brad Harrison, founder and managing partner at Scout Ventures, said in the release. “This is based on 100 years of science and we’re finally approaching a commercial product … We’re proud to lead this round and support Casimir’s journey from applied science to deployed technology.”

Casimir says it aims to scale its technology across the ”full power spectrum,” including large-scale energy systems that can power homes, commercial infrastructures and electric vehicles.

Casimir's scientific work has been supported by DARPA-funded nanofabrication research and its technology was incubated at the Limitless Space Institute (LSI). LSI is a nonprofit that works to innovate interstellar travel and was founded by Kam Ghaffarian. Technology investor and serial entrepreneur Ghaffarian has been behind companies like X-energy, Intuitive Machines, Axiom Space and Quantum Space.

Harold “Sonny” White, founder and CEO of Casimir, believes the technology can power devices for years without replacements.

“Millions of devices will operate for years without a battery ever needing to be replaced or recharged because we have engineered a customized Casimir cavity into hardware capable of producing persistent electrical power,” White added in the release. “I spent nearly two decades at NASA studying how we power humanity’s future. That work led me to the Casimir effect and the quantum vacuum, where new tools have allowed us to build on a century of scientific knowledge and bring abundant power to the world.”
