Every company with a business based in whole or in part on important intellectual property should protect that property with regularly scheduled intellectual property “audits.” Failing to do so may not only endanger valuable, company-owned patents and trademarks, but also make the business less profitable than it could be.

An IP audit is especially critical when a business is being sold, when a company is planning to buy another business, when a patent is being challenged by a competitor, when a company is looking for new financing or going public, and when there is a change in top management or employees in critical positions have left. A regularly scheduled IP audit can prevent panic, confusion and unwelcome surprises when these major events occur, because management will already have a good working knowledge of the status of all intellectual property.

To begin with, a thorough audit separates the wheat from the chaff. Which patents are central to the company’s business and must be carefully maintained in force? Are there other patents that are no longer important or have been superseded by newer developments and can safely be ignored and allowed to lapse?

Patents should be filed wherever the company’s products are sold and fees on all important patents must be carefully kept up to date. Fees to maintain international patents are often especially expensive but should be updated when necessary, nonetheless. Sometimes, when a company’s trademarks are reviewed, management learns that they have never been federally registered.

Auditors also may find that existing patents are no longer adequate to protect the products that are actually being sold. The products may have “moved on” through further development or application to new uses, but the relevant patents have not. Those patents should be updated immediately with new filings. It’s also critical to determine whether the products made and sold by the company could possibly infringe patents held by competitors—or whether the reverse is true, that other companies’ products are infringing the patents held by the company being audited.

A careful examination of intellectual property can also result in positive developments: auditors may discover that some patents are more valuable than anyone knew and can be licensed to produce another revenue stream for the company—or licensing can be expanded beyond the present level.

Beyond the focus on patents and trademarks, an IP audit should entail a close examination of all contracts and agreements relating to intellectual property. Pinning down exactly who owns the property is just as important as keeping patents up to date. This entails delving into development agreements, nondisclosure agreements, employment agreements, work-for-hire and sales contracts, to make sure ownership of a company’s intellectual property has not been ceded to, or shared with, a third party.

Software is particularly problematic when it comes to inadvertent infringement of the rights of others. What software is being used internally? Where did it come from and what are the limitations on its use? IT professionals don’t always realize that even open-source code requires a license.

This entire process also needs to be applied to analyzing the intellectual property of a prospective acquisition. Investigators may discover that patents belonging to the acquisition are not all appropriate for the acquiring company’s products, fees are not up to date or there are issues with IP ownership or validity. All of these factors may result in substantial savings on the purchase—or a decision not to purchase at all.

Baylor scientist lands $2M grant to explore links between viruses and Alzheimer’s

Alzheimer’s research

A Baylor College of Medicine scientist will begin exploring the possible link between Alzheimer’s disease and viral infections thanks to a $2 million grant awarded in March.

Dr. Ryan S. Dhindsa is an assistant professor of pathology & immunology at Baylor and a principal investigator at Texas Children’s Duncan Neurological Research Institute (Duncan NRI). He hypothesizes that Alzheimer’s may have some link to previous viral infections contracted by the patient. To study this intriguing possibility, the American Brain Foundation has gifted him the Cure One, Cure Many award in neuroinflammation.

“It is an honor to receive this support from the Cure One, Cure Many Award. Viral infections are emerging as a major, underappreciated driver of Alzheimer's disease, and this award will allow our team to conduct the most comprehensive screen of viral exposures and host genetics in Alzheimer's to date, spanning over a million individuals,” Dhindsa said in a news release. “Our goal is to identify which viruses matter most, why some people are more vulnerable than others, and ultimately move the field closer to new therapeutic strategies for patients.”

Roughly 150 million people worldwide will suffer from Alzheimer’s by 2050, making it the most common cause of dementia in the world. Despite this, scientists are still at a loss as to what exactly causes it.

Dhindsa’s research is part of a new range of theories that certain viral infections may trigger Alzheimer’s. His team will take a two-fold approach. First, they will analyze the medical records of more than a million individuals looking for patterns. Second, they will analyze viral DNA in stem cell-derived brain cells to see how the infections could contribute to neurological decay. The scale of the genomic data gathering is unprecedented and may highlight a link that traditional studies have missed.

Also joining the project are Dr. Caleb Lareau of Memorial Sloan Kettering Cancer Center and Dr. Artem Babaian of the University of Toronto. Should a link be found, it would open the door to using anti-virals to prevent or treat Alzheimer’s.

Tesla Robotaxi service officially launches in Houston and Dallas

Future of the Roads

Tesla’s Robotaxi service has taken to the streets of Houston. In a brief statement Saturday, April 18 on its X social media account, Tesla Robotaxi says the autonomous rideshare service just launched in Texas’ two biggest metro areas — Houston and Dallas.

“Try Tesla Robotaxi in Dallas & Houston!” Tesla CEO Elon Musk says in a reposting on X of the Robotaxi announcement.

One of Robotaxi’s competitors, Alphabet-owned Waymo, beat the Tesla service to the Dallas, Houston, and Austin markets. Another competitor, Amazon-owned Zoox, has Dallas flagged for its autonomous rideshare service.

Robotaxi previously kicked off in Austin, where Tesla is based and manufactures electric vehicles, and the San Francisco Bay Area. Nearly 50 Robotaxis operate in Austin, where the service’s inaugural rides happened last year, and more than 500 in the San Francisco area.

Of the three rides logged in a 31-square-mile area in Dallas as of Monday morning, the average fare was $7.96 and the average trip was 3.5 miles, according to an online tracker of autonomous rideshare services. The tracker showed only one Robotaxi was on the roads in Dallas.

As of Monday morning, a 25-square-mile area in Houston had two Robotaxis on the road, according to the online tracker. The average fare for five recorded rides was $11.34 and the average trip was six miles.

“We want Robotaxi pricing to be simple and easy for you to understand,” according to the Robotaxi website. “Initially, as part of our introductory program, we will charge a simple, affordable rate plus applicable taxes and fees for all rides within the available service area.”

The tracker shows the Robotaxi in Dallas did not have a human aboard to monitor each trip, and only one of Houston’s two Robotaxis did not have a human monitor in the driver’s seat.

For now, all passengers ride in Tesla Model Y cars. Robotaxi operates from 6 am-2 am daily.

To use the service, you first must download the Robotaxi app, which works only on iPhones.

Robotaxi lets you stream music and adjust climate settings and seat positioning from the Robotaxi app or the vehicle’s touchscreen. Climate and media settings are stored in your Robotaxi profile and automatically transfer from one vehicle to another. If you own a Tesla, certain profile settings and media preferences are available in your own car as well as in a Robotaxi.

In January at the World Economic Forum in Davos, Switzerland, Musk said a “widespread” network of driverless rideshare vehicles would be operating in the U.S. by the end of this year, CNBC reported.

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.
