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."

Venus Aerospace closes $91 million Series B 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.
