Vivian Wesson – Marsh McLennan

DEI remains an everlasting effort for IP counsel

In spring 1992, Vivian Wesson was a junior at Pomona College, east of Los Angeles, and her semi-autobiographical play about growing up as “an assimilated American with African American roots and being in between cultures” was getting produced.

As production occurred, a jury in Simi Valley acquitted four police white officers of assault charges in the beating of Rodney King, a Black man charged with a traffic violation. Three of the four officers were also acquitted of using excessive force. The verdicts set off six days of unrest and riots in Los Angeles.

“I remember the fervor, outcry and pain, and the reflection on how to prevent it from happening again,” she says. “But the efforts waned when the news cycle closed.”

Creating change has been a professional and personal cause for Wesson ever since. As the chief intellectual property counsel for Marsh McLennan, she protects the global professional services firm and helps guide its cybersecurity efforts. As crucial as that’s become during the COVID-19 pandemic, Wesson says her advocacy for women and minorities is just as crucial.

“I want to have led by example. I’ve benefited greatly from mentoring at various stages in my life and work,” Wesson says. “I act as a coach, but do so by listening and leading someone, even if they know they may fail on occasion. You have to let them know they’ll have their own experiences and they can build on them.”

Protecting the products

Marsh McLennan dates to the cataclysmic 1871 fire that destroyed Chicago. Shortly afterwards, Dan Bomar arrived and founded an agency underwriting fire insurance. Almost 30 years later, Henry Marsh, who’d joined the original firm in 1885, guided U.S. Steel as it self-insured its operations. Shortly after that, Marsh and competitor Donald McLennan joined forces to insure the Chicago Burlington & Quincy railroad.

Now celebrating its 150th anniversary, Marsh McLennan has four insurance and consulting business units, including reinsurance—covering insurers from the risk of major claims. Wesson, who recalls having to ask what reinsurance was when she joined the company in 2005, now protects IP throughout each business unit. She also ensures that innovations and new products from one business group can be used by others.

Her work has led to Marsh McLennan receiving its first patent in 2011 for real time loss forecasts from catastrophe events. Wesson adds a partnership with CSC is crucial for defending Marsh McLennan’s digital brand solutions.

“CSC acts as a shield. They’ve been a lifesaver,” Wesson says, because they monitor and protect Marsh McLennan’s intellectual assets from infringement and root out cyber threats, such as email fraud, that have been a near-daily occurrence for the past 18 months. Fernando Cevallos, the product director of CSC’s Fraud Protection unit, also enjoys the collaboration.

“In today’s ever expanding digital world, businesses need to have a comprehensive view of their entire online presence and be aware of any possible threat to their operation,” he says. “CSC is honored to collaborate with excellent lawyers like Vivian Wesson and the great companies they represent.”

Advocating for people and planet

Wesson’s efforts to promote diversity, equity and inclusion at Marsh McLennan began more than a decade ago. After noting she was one of five Black people attending a recent senior leadership team meeting of 150 employees, she adds those efforts took on additional resonance considering events in 2020, including the murders of George Floyd and Ahmaud Arbery.

At Marsh McLennan, Wesson sits on the legal and compliance community action committee, as well as its recruitment and retention team. She describes DEI efforts as an inverted “V” problem—saying too many efforts in society have fallen off the edge.

“We’re seeing companies create the efforts, but they need to show how the money is spent and the results,” Wesson says.

Wesson also works with the New York State Bar Association’s Task Force on Racism, Social Equity and the Law, chairing its committee on attorney professionalism and co-chairing its environmental justice committee. It’s part of an effort to examine structural racism and its impact on criminal justice, economic opportunities, environmental justice, financial literacy, education and health, Wesson says.

One of the initiatives supported by the New York State Bar Association is the Long Island Clean Water Partnership. That resonates with Wesson because her family’s home in Gary, Indiana, sat at the edge of a landfill. Placing potential environmental hazards near lower income neighborhoods isn’t new, but she says ending the practice is crucial for safety and social justice.

Wesson is also convening what she calls the “League of Extraordinary Women,” a startup bringing Black women together to provide funding and resources to help unrepresented and marginalized people.

“If we’re using this moment and have billions of dollars to improve infrastructure, we can get at structural issues,” she says.

Journey with a cause

Wesson left Gary to attend boarding school in New Hampshire, then earned her bachelor’s degree in history from Pomona College in Southern California in 1993.

After graduating, she joined a private law firm as manager of its real estate paralegal group, taking her to New York. The work piqued her interest in a law career, and in 1997, she enrolled at Fordham Law School. She earned her J.D. in 2000 and became an associate at the firm of O’Melveny & Myers LLC.

In 2005, Wesson joined Marsh McLennan as corporate counsel. In January 2011, she became assistant secretary at its Guy Carpenter reinsurance subsidiary and was promoted to senior vice president in April 2015. She held the role until her April 2020 promotion at Marsh McLennan.

“Everyone has an element of unconscious bias, believing in stereotypes, and you have to relearn to prevent it from happening,” Wesson says. “It’s wearying, it can be exhausting, but get involved. If you think you don’t have the time to do it, you do. If you think you’re not being influential, you are.”

As promised in advance, my feature in Vanguard has increased my visibility within the profession and prompted more than a few people I have not communicated with recently to reconnect. One of the Italian law firms I have used in the past is now in the process of interviewing me for an article on their website and tweeting out the feature story. Activity and the number of people connecting with me on LinkedIn has soared, which is great. The Vanguard writers and editorial staff were great to work with—highly professional and made the effort to make the experience both fun and rewarding (they were also respectful of the time pressures and demands all lawyers face). I was very pleased with the experience and the final outcome. Needless to say, I have been very pleased. All in all working with Vanguard has been a very positive experience which generated good publicity for both Shawcor and myself. My sincere thanks.

I was honored to be the subject of an article. I enjoy reading Vanguard articles and seeing how other attorneys got to their positions and see their jobs. It's also interesting to see how different law firms partner with the subjects of the articles.

The piece highlighting my company, Bob Baker Enterprises, Inc., came out fabulous. Our company is in the new and used car sales and service industry. Everyone was great to work with and extremely professional. They produced a high-quality product and have provided expert assistance and guidance post-production of the article.

It was a great honor to be featured in Vanguard Law. Working with every member of the team, from the initial interview with Erin Clark, through production with Victor Martins, writing the article with Taryn Plumb and creating the final content with Dave Gushee, was a true pleasure. Everyone was very professional, enthusiastic and supportive, and their creative approach and positive attitude clearly came through in the final product.
