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.

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."

Planned UT Austin med center, anchored by MD Anderson, gets $100M gift

med funding

The University of Texas at Austin’s planned multibillion-dollar medical center, which will include a hospital run by Houston’s University of Texas MD Anderson Cancer Center, just received a $100 million boost from a billionaire husband-and-wife duo.

Tench Coxe, a former venture capitalist who’s a major shareholder in chipmaking giant Nvidia, and Simone Coxe, co-founder and former CEO of the Blanc & Otus PR firm, contributed the $100 million—one of the largest gifts in UT history. The Coxes live in Austin.

“Great medical care changes lives,” says Simone Coxe, “and we want more people to have access to it.”

The University of Texas System announced the medical center project in 2023 and cited an estimated price tag of $2.5 billion. UT initially said the medical center would be built on the site of the Frank Erwin Center, a sports and entertainment venue on the UT Austin campus that was demolished in 2024. The 20-acre site, north of downtown and the state Capitol, is near Dell Seton Medical Center, UT Dell Medical School and UT Health Austin.

Now, UT officials are considering a bigger, still-unidentified site near the Domain mixed-use district in North Austin, although they haven’t ruled out the Erwin Center site. The Domain development is near St. David’s North Medical Center.

As originally planned, the medical center would house a cancer center built and operated by MD Anderson and a specialty hospital built and operated by UT Austin. Construction on the two hospitals is scheduled to start this year and be completed in 2030. According to a 2025 bid notice for contractors, each hospital is expected to encompass about 1.5 million square feet, meaning the medical center would span about 3 million square feet.

Features of the MD Anderson hospital will include:

Inpatient care
Outpatient clinics
Surgery suites
Radiation, chemotherapy, cell, and proton treatments
Diagnostic imaging
Clinical drug trials

UT says the new medical center will fuse the university’s academic and research capabilities with the medical and research capabilities of MD Anderson and Dell Medical School.

UT officials say priorities for spending the Coxes’ gift include:

Recruiting world-class medical professionals and scientists
Supporting construction
Investing in technology
Expanding community programs that promote healthy living and access to care

Tench says the opportunity to contribute to building an institution from the ground up helped prompt the donation. He and others say that thanks to MD Anderson’s participation, the medical center will bring world-renowned cancer care to the Austin area.

“We have a close friend who had to travel to Houston for care she should have been able to get here at home. … Supporting the vision for the UT medical center is exactly the opportunity Austin needed,” he says.

The rate of patients who leave the Austin area to seek care for serious medical issues runs as high as 25 percent, according to UT.

New Rice Brain Institute partners with TMC to award inaugural grants

brain trust

The recently founded Rice Brain Institute has named the first four projects to receive research awards through the Rice and TMC Neuro Collaboration Seed Grant Program.

The new grant program brings together Rice faculty with clinicians and scientists at The University of Texas Medical Branch, Baylor College of Medicine, UTHealth Houston and The University of Texas MD Anderson Cancer Center. The program will support pilot projects that address neurological disease, mental health and brain injury.

The first round of awards was selected from a competitive pool of 40 proposals, and will support projects that reflect Rice Brain Institute’s research agenda.

“These awards are meant to help teams test bold ideas and build the collaborations needed to sustain long-term research programs in brain health,” Behnaam Aazhang, Rice Brain Institute director and co-director of the Rice Neuroengineering Initiative, said in a news release.

The seed funding has been awarded to the following principal investigators:

Kevin McHugh, associate professor of bioengineering and chemistry at Rice, and Peter Kan, professor and chair of neurosurgery at the UTMB. McHugh and Kan are developing an injectable material designed to seal off fragile, abnormal blood vessels that can cause life-threatening bleeding in the brain.
Jerzy Szablowski, assistant professor of bioengineering at Rice, and Jochen Meyer, assistant professor of neurology at Baylor. Szablowski and Meyer are leading a nonsurgical, ultrasound approach to deliver gene-based therapies to deep brain regions involved in seizures to control epilepsy without implanted electrodes or invasive procedures.
Juliane Sempionatto, assistant professor of electrical and computer engineering at Rice, and Aaron Gusdon, associate professor of neurosurgery at UTHealth Houston. Sempionatto and Gusdon are leading efforts to create a blood test that can identify patients at high risk for delayed brain injury following aneurysm-related hemorrhage, which could lead to earlier intervention and improved outcomes.
Christina Tringides, assistant professor of materials science and nanoengineering at Rice, and Sujit Prabhu, professor of neurosurgery at MD Anderson, who are working to reduce the risk of long-term speech and language impairment during brain tumor removal by combining advanced brain recordings, imaging and noninvasive stimulation.

The grants were facilitated by Rice’s Educational and Research Initiatives for Collaborative Health (ENRICH) Office. Rice says that the unique split-funding model of these grants could help structure future collaborations between the university and the TMC.

The Rice Brain Institute launched this fall and aims to use engineering, natural sciences and social sciences to research the brain and reduce the burden of neurodegenerative, neurodevelopmental and mental health disorders. Last month, the university's Shepherd School of Music also launched the Music, Mind and Body Lab, an interdisciplinary hub that brings artists and scientists together to study the "intersection of the arts, neuroscience and the medical humanities."

Your data center is either closer than you think or much farther away

houston voices

A new study shows why some facilities cluster in cities for speed and access, while others move to rural regions in search of scale and lower costs. Based on research by Tommy Pan Fang (Rice Business) and Shane Greenstein (Harvard).

Key findings:

Third-party colocation centers are physical facilities in close proximity to firms that use them, while cloud providers operate large data centers from a distance and sell access to virtualized computing resources as on‑demand services over the internet.
Hospitals and financial firms often require urban third-party centers for low latency and regulatory compliance, while batch processing and many AI workloads can operate more efficiently from lower-cost cloud hubs.
For policymakers trying to attract data centers, access to reliable power, water and high-capacity internet matter more than tax incentives.

Recent outages and the surge in AI-driven computing have made data center siting decisions more consequential than ever, especially as energy and water constraints tighten. Communities invest public dollars on the promise of jobs and growth, while firms weigh long-term commitments to land, power and connectivity.

Against that backdrop, a critical question comes into focus: Where do data centers get built — and what actually drives those decisions?

A new study by Tommy Pan Fang (Rice Business) and Shane Greenstein (Harvard Business School) provides the first large-scale statistical analysis of data center location strategies across the United States. It offers policymakers and firms a clearer starting point for understanding how different types of data centers respond to economic and strategic incentives.

Forthcoming in the journal Strategy Science, the study examines two major types of infrastructure: third-party colocation centers that lease server space to multiple firms, and hyperscale cloud centers owned by providers like Amazon, Google and Microsoft.

Two Models, Two Location Strategies

The study draws on pre-pandemic data from 2018 and 2019, a period of relative geographic stability in supply and demand. This window gives researchers a clean baseline before remote work, AI demand and new infrastructure pressures began reshaping internet traffic patterns.

The findings show that data centers follow a bifurcated geography. Third-party centers cluster in dense urban markets, where buyers prioritize proximity to customers despite higher land and operating costs. Cloud providers, by contrast, concentrate massive sites in a small number of lower-density regions, where electricity, land and construction are cheaper and economies of scale are easier to achieve.

Third-party data centers, in other words, follow demand. They locate in urban markets where firms in finance, healthcare and IT value low latency, secure storage, and compliance with regulatory standards.

Using county-level data, the researchers modeled how population density, industry mix and operating costs predict where new centers enter. Every U.S. metro with more than 700,000 residents had at least one third-party provider, while many mid-sized cities had none.

ImageThis pattern challenges common assumptions. Third-party facilities are more distributed across urban America than prevailing narratives suggest.

Customer proximity matters because some sectors cannot absorb delay. In critical operations, even slight pauses can have real consequences. For hospital systems, lag can affect performance and risk exposure. And in high-frequency trading, milliseconds can determine whether value is captured or lost in a transaction.

“For industries where speed is everything, being too far from the physical infrastructure can meaningfully affect performance and risk,” Pan Fang says. “Proximity isn’t optional for sectors that can’t absorb delay.”

The Economics of Distance

For cloud providers, the picture looks very different. Their decisions follow a logic shaped primarily by cost and scale. Because cloud services can be delivered from afar, firms tend to build enormous sites in low-density regions where power is cheap and land is abundant.

These facilities can draw hundreds of megawatts of electricity and operate with far fewer employees than urban centers. “The cloud can serve almost anywhere,” Pan Fang says, “so location is a question of cost before geography.”

The study finds that cloud infrastructure clusters around network backbones and energy economics, not talent pools. Well-known hubs like Ashburn, Virginia — often called “Data Center Alley” — reflect this logic, having benefited from early network infrastructure that made them natural convergence points for digital traffic.

Local governments often try to lure data centers with tax incentives, betting they will create high-tech jobs. But the study suggests other factors matter more to cloud providers, including construction costs, network connectivity and access to reliable, affordable electricity.

When cloud centers need a local presence, distance can sometimes become a constraint. Providers often address this by working alongside third-party operators. “Third-party centers can complement cloud firms when they need a foothold closer to customers,” Pan Fang says.

That hybrid pattern — massive regional hubs complementing strategic colocation — may define the next phase of data center growth.

Looking ahead, shifts in remote work, climate resilience, energy prices and AI-driven computing may reshape where new facilities go. Some workloads may move closer to users, while others may consolidate into large rural hubs. Emerging data-sovereignty rules could also redirect investment beyond the United States.

“The cloud feels weightless,” Pan Fang says, “but it rests on real choices about land, power and proximity.”
