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.

Rice research: What innovations can be used to borrow against?

Houston voices

For companies and leaders, patents represent important assets. They’re a marker of innovation and tech development. But patents do so much more than protect intellectual property. Firms increasingly deploy them as collateral to secure loans. Between 1995 and 2013, the number of patents pledged as loan collateral increased from about 10,000 to nearly 50,000. Forty percent of U.S. patenting firms have used patents as collateral.

However, patents are intangible assets, and their liquidity and liquidation value are difficult to assess. To evaluate an individual patent, lenders must consider the invention space to which the patent belongs. A patent’s linkage to prior inventions can provide important information for lenders, as the linkage affects the extent to which the patent under consideration may be redeployed and potentially purchased by other firms in the case of loan default.

Rice Business professor Yan Anthea Zhang examined more closely how this market operates and how both lenders and borrowers can make more informed decisions on which patents make appealing collateral. In their paper, “Which patents to use as loan collateral? The role of newness of patents' external technology linkage,” Zhang, who specializes in strategic management, and her co-authors studied the data on 107,180 U.S. semiconductor patents owned by 436 U.S. firms. The team focused on semiconductor patents because the semiconductor industry involves intensive innovation, which leads to many patent applications and grants. The market for semiconductor patents is an active and well-functioning market, given specialization in different stages of the innovation process and the growing technological market. Information on whether a patent was used as loan collateral came from the USPTO Patent Assignments Database.

Zhang and her colleagues argue that lenders prefer patents linked to prior inventions that are relatively new because these patents are riding on recent technology waves and are less likely to become obsolete. As a result, such patents are likely to remain deployable to other firms in the future. However, patents that are based upon too new prior inventions might not prove to be commercially viable and carry higher risk for lenders.

As a result of this research, Zhang and her colleagues found an inverted U-shape relationship to demonstrate the likelihood that a patent will be used as loan collateral. On one end, patents based upon the newest prior inventions, on the other, patents based upon mature prior inventions. The curve of the U-shape represents the sweet spot for patent collateral—the patents’ technological base is new enough to be relevant and competitive with other firms in its invention space, but not so new that it has yet to prove market success.

Zhang’s team also found that the impact of external linkage also varies depending on borrower attributes, especially the borrowers’ expertise in the invention space. If a borrower is a technological leader in the invention space, the market tends to give the borrower credit, and as a result, even if its patents are based upon very new prior inventions, its patents are still likely to be accepted as collateral.

Leading lady

A Houston inventor is being recognized for her leadership within cardiovascular regenerative medicine. Doris A. Taylor from the Texas Heart Institute has been named among the National Academy of Inventors' 54 academic inventors to the spring 2019 class of NAI Senior Members.

Taylor's work involves finding alternatives for the current practices for organ transplants, including the whole organ decellularization/recellularization technologies she developed in 2008.

"Dr. Taylor's work has revolutionized the field by making it possible to bioengineer scaffolds that effectively mimic natural organs," says Dr. Darren Woodside, Texas Heart Institute's vice president for research, in a news release. "The three U.S. patents she currently holds have spun off 28 international patents, stimulating the worldwide tissue engineering industry. Her current research team is refining these technologies and developing others, potentially revolutionizing the transplantation industry and eliminating wait lists for life-saving transplantable organs."

NAI selects its honorees by identifying their impact on the welfare of society, the release reads, and have proven success with their patents, licensing, and commercialization.

NAI Senior Members are active faculty, scientists and administrators from its Member Institutions who have demonstrated remarkable innovation producing technologies that have brought, or aspire to bring, real impact on the welfare of society. They also have proven success in patents, licensing and commercialization.

An individual's nomination for the NAI Senior Member class by its supporting institution is a distinct honor and a significant way for the organization to publicly recognize its innovators on a national level.At their host institutions, Senior Members foster a spirit of innovation, while educating and mentoring the next generation of inventors.

The new class of NAI Senior Members includes representatives from 32 institutions. Texas A&M University has two researchers in the class — Robert Balog, an associate professor in the Department of Electrical and Computer Engineering, and Balakrishna Haridas, a professor of practice in the Department of Biomedical Engineering and executive director for technology commercialization and entrepreneurship for the Texas A&M Engineering Experiment Station.

This latest class of NAI Senior Members represents 32 research universities and government and non-profit research institutes. They are named inventors on over 860 issued U.S. patents. In February, two Houston inventors were named to the inaugural class of senior members.

"NAI Member Institutions support some of the most elite innovators on the horizon. With the NAI Senior Member award distinction, we are recognizing innovators that are rising stars in their fields," says Paul R. Sanberg, NAI president, in the release. "This new class is joining a prolific group of academic visionaries already defining tomorrow."

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.

Houston ranks high on best cities for small-business expansion report

business growth

For small businesses looking to expand, Houston might be the right place.

Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

“Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

“The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

“For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

“Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

Of course, money fuels small-business expansion in the Houston area or anywhere else.

According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

Altogether, the 7(a) and 505 loans exceeded $1 billion.

The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.
