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.

Rice University's Shell-backed hub announces latest research grants

low carbon funding

Several clean energy research teams have been awarded grants from a Rice University hub that focuses on innovating zero-emissions technology.

The Carbon Hub has awarded seven seed grants to research teams working on solutions for clean energy. The selections represent the first from the hub, which was established in 2019 following a $10 million gift from Shell. The hub's goal is to fundamentally change how the world uses hydrocarbons and to lead $100 million of science and engineering initiatives.

"Our starting point is utilizing methane and other light hydrocarbons to co-produce clean hydrogen and high-value materials that can outcompete and displace heavy CO2 emitters like metals, construction ceramics and fertilizers," says Carbon Hub Director Matteo Pasquali in a news release.

The selected proposals, according to the release, are as follows:

  • Cambridge's Adam Boies, Simone Hochgreb, James Elliot and Matthew Juniper will investigate the fundamental kinetics of catalytic reactions that produce carbon nanotubes from methane. The research aims to gather necessary information for the design and scaleup of reactors for high-yield production.
  • UC Berkeley's Roya Maboudian, Paulo Monteiro, Carlo Carraro and Jiaqi Li will use experimental and computational techniques to investigate cement reinforced with carbon fibers. The team will investigate a wide range of fibers and concrete binders to find optimal blends.
  • Rice's Caroline Masiello and Daniel Cohan will use bench-scale experiments and computer models to investigate whether methane-derived carbon could reduce urban smog and/or reduce atmospheric carbon dioxide concentrations if added to soil as it is in popular charcoal soil amendments called biochar.
  • IMDEA's Juan Vilatela will address engineering challenges for using non-woven carbon nanotube fabrics in place of lithium battery components made of aluminum and copper. Replacing those metal components could eliminate more than 4 million tons of annual atmospheric carbon dioxide emissions.
  • Rice's Geoffrey Wehmeyer, Junichiro Kono and Matthew Foster will lay the groundwork for replacing metal power transmission cables with carbon nanotube fibers. To allow side-by-side comparisons, they will investigate fundamental electrical and thermal conductivity at scales ranging from individual nanotubes to bundles of tubes, fibers of bundles and yarns of fibers.
  • Milan Polytechnic's Matteo Maestri and Matteo Pelucchi aim to pave the way for optimized co-production of hydrogen and carbon nanotubes by developing descriptive frameworks for competing catalytic reactions. The information would allow process engineers to minimize production of unwanted soot in large-scale reactors for nanotube production.
  • MIT's Mark Goulthorpe and UDRI's Paul Kladitis will test the performance of carbon nanotube materials in a variety of composites that could be used to construct homes and other buildings. The work complements Goulthorpe's CarbonHouse, a demonstration project supported by the Advanced Research Projects Agency-Energy to validate the use of carbon from methane pyrolysis as both structural and non-structural building materials.

Shell commits to $10M carbon initiative with Rice University, Houston startup acquired by Honeywell, and more innovation news

Short Stories

Even toward the end of the year and amid the holiday season, Houston's innovation news can be a lot to keep up with. Here are seven short stories of Houston innovation — from an exit for a Houston startup and a multimillion-dollar clean energy commitment from Shell to new national recognitions for Houston and 2020 plans unveiled for MassChallenge in Houston.

Shell commits $10 million to new Carbon Hub at Rice University

Rice University has introduced its Shell-backed Carbon Hub — a research initiative to innovate zero-emissions technologies. According to a news release, Shell has committed to a $10 million arrangement for the hub.

"Trying to address climate change is like playing whack-a-mole; you think you're making something better, and you realize that made something else get worse," says Carbon Hub director, Matteo Pasquali, in the release. "For example, you make cars more fuel efficient by removing weight, and then realize you've increased CO2 emissions by using more aluminum and carbon fibers. Or you try to fix CO2 into a useful product, and you realize you now need much more energy than you had gotten by making the CO2 in the first place."

The plan is to "fundamentally change how the world uses hydrocarbons," reads the release. Rather than burning hydrocarbons for fuel, creating carbon dioxide, the hydrocarbons "will be split to make clean-burning hydrogen fuel and solid carbon materials that can be used to make buildings, cars, clothing and more."

Through the partnership with Shell — and other potential partners — the hub will help fund and lead $100 million of science and engineering initiatives. The inaugural meeting for the hub is expected to be early next year and will be hosted by The Center for Energy Studies at Rice's Baker Institute for Public Policy.

"Providing energy to the world's population in an economically and environmentally sustainable manner is the global energy challenge," says Ken Medlock, senior director of the Center for Energy Studies, in the release. "In part, this will require new technologies and forward-looking, creative thinking, which is exactly what Carbon Hub offers."

Houston ranks among 15 U.S. hot spots for women in tech

Ranking It

Houston is soaring among the best places in the U.S. for women in tech, a new report says. Houston ranked No. 15 nationwide in SmartAsset's new report, "Best and Worst Cities for Women in Tech — 2026 Study," which compared the 50 biggest U.S. cities across four metrics:

  • Gender pay gap — women's median earnings as a percentage of men’s median earnings in tech
  • The share of all tech workers that are women
  • The overall concentration of employment for tech workers, defined as "tech workers as a share of the local workforce"
  • Women tech workers’ median earnings, adjusted for regional price parity
For the purpose of the study, tech workers are defined as "city residents employed in computer and mathematical occupations." The study's findings show that fewer than 9,500 tech workers in Houston are women, or 25.6 percent of the total tech workforce in the city. In total, tech workers in general make up less than 3 percent of the Houston workforce.Despite the high ranking, women tech workers in Houston have a sizeable gap to cross to receive equal pay compared to their male counterparts in the same industry. Women tech workers make just over $97,000 in median earnings after adjusting for regional price parity, which is only 93 percent of what male tech workers make, SmartAsset found.

There are only two U.S. cities where women in tech earn more than what their male counterparts: Miami and Memphis, Tennessee. Women tech workers in Miami make an adjusted $88,650 in median earnings, or 101.7 percent of what men in tech make. In Memphis, women make $84,718 in adjusted earnings, or 101.5 percent of what men in tech earn.

The findings also assert that women remain underrepresented in the nation's overall tech sector, despite making up nearly half of the total workforce. Only 22.6 percent of the country's tech labor force is made up of women, according to the Equal Employment Opportunity Commission."Opportunities for women in tech can vary considerably by location, and these differences shape access to jobs, career advancement and earning potential," the report's author wrote. "In some places, women account for a larger share of tech workers, face narrower pay gaps and enjoy a stronger local labor market. In others, they may encounter a more challenging career environmentThe six other Texas cities that earned spots in the report are Austin (No. 6), Fort Worth (No. 26), Dallas (No. 32), Arlington (No. 38), San Antonio (No. 42), and El Paso (No. 49).

The top 10 best U.S. cities for women in tech are:

  • No. 1 – San Jose, California
  • No. 2 – Seattle, Washington
  • No. 3 – San Francisco, California
  • No. 4 – Atlanta, Georgia
  • No. 5 – Baltimore, Maryland
  • No. 6 – Austin, Texas
  • No. 7 – Oakland, California
  • No. 8 – Portland, Oregon
  • No. 9 – Boston, Massachusetts
  • No. 10 – Minneapolis, Minnesota

ARIX Technologies

Energytech startup ARIX Technologies has developed a semiautonomous VENUS crawler robot to detect corrosion under insulation before it becomes a failure. The robots climb insulated piping in refineries, chemical plants and energy facilities to capture inspection data without removing insulation or building scaffolding. ARIX's inspection portal then turns information from the inspection into data a company can act on.

ARIX was founded in 2017 by Dianna Liu, who serves as director, and Head of Product Petter Wehlin. Craig Malloy serves as CEO. The company has raised more than $22 million in seed funding and a Series A round, according to its application.

Bairitone Health

Healthtech startup Bairitone Health is bringing anatomy imaging for sleep apnea to the home environment. The company's platform maps users' anatomy during natural sleep using a facial patch to determine the root cause of airway obstruction. It then offers effective therapies for each patient.

The company was founded in 2022 in the Texas Medical Center's Biodesign program by CEO Meagan Pitcher, CTO Onur Kilic and chief medical officer Britt Cross. It was a member of Activate Houston's inaugural cohort and has participated in numerous accelerators and incubators. The company raised an oversubscribed seed round for $2.4 million earlier this year and received Breakthrough Device Designation from the Food and Drug Administration in April.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

ParaDocs Health

Healthtech startup ParaDocs Health is developing a clinical intelligence platform that helps doctors and care teams streamline administrative tasks and make better use of patient records. Its technology organizes fragmented clinical data into actionable insights, helping care teams identify gaps in care, assess patient risks and simplify documentation and reimbursement.
