How Todd Mensing and AZA Handle Disputes Across Energy, IP, and Contract Cases

AZA Law, formally Ahmad, Zavitsanos & Mensing, has operated as a Houston trial firm since 2001, built around a group of lawyers who try cases rather than settle them. Chambers USA ranked the firm for its 12th consecutive year in 2025, describing it as a home for “true courtroom lawyers” with a track record in complex commercial and intellectual property disputes. Name partner Todd Mensing of AZA holds board certification in Civil Trial Law, a credential awarded to an average of fewer than five Texas attorneys per year, and has tried more than sixty cases across energy, patent, contract, trade secret, and employment matters. Specific documented outcomes, drawn from court records and firm summaries, show how the practice actually divides.

AZA’s core categories, as described by Chambers and reflected in the firm’s own case archive, include commercial litigation, intellectual property, energy, trade secrets, non-competes, and corporate investigations. Best Lawyers recognized the firm as Tier 1 in Houston for commercial litigation, intellectual property, employment law for management, construction litigation, personal injury litigation for defendants, and appellate work in its most recent edition. For Todd Mensing and AZA, those categories don’t stay neatly separated; the trial record runs across all of them.

Energy Disputes and the Subsurface

Among AZA’s documented energy cases, the SilverBow Resources litigation produced one of the most scrutinized Texas oil-and-gas verdicts of recent years. SilverBow Resources Operating LLC and co-plaintiff El Dorado Gas & Oil, Inc. sued ETC Field Services, LLC, an affiliate of Energy Transfer, alleging that the defendant’s injection of natural gas processing byproducts trespassed on subsurface formations the plaintiffs had the right to occupy.

Todd Mensing at AZA served as one of the trial counsel for SilverBow, alongside firm partners Taylor Freeman, Jane Robinson, and Cameron Byrd. A McMullen County jury in the 343rd District Court returned a combined award of $41.8 million: $24.5 million to SilverBow and $17.3 million to El Dorado. Verdict Search and The National Law Journal placed the result on their national top-verdict lists for 2023.

Taking Patent Claims Through the Federal Circuit

Chambers ranked AZA’s intellectual property practice for the fifth consecutive year in 2025 and the firm’s commercial litigation category for the 12th. IAM Patent 1000, which tracks patent litigation specialists, has listed the firm and ranked Todd Mensing of AZA as a leading IP litigator. His patent and IP work spans infringement claims, trade secret disputes, and commercial technology cases, often for energy and industrial sector clients.

One of the firm’s most closely followed patent wins involved a challenge to Google over spreadsheet navigation patents. AZA represented Data Engine Technologies LLC, whose patents described “a highly intuitive, user-friendly interface with familiar notebook tabs for navigating the three-dimensional worksheet environment.” A Delaware district court had dismissed those claims as covering abstract ideas ineligible for patent protection. The Federal Circuit reversed that ruling in October 2018, reinstating three of the patents and holding that the claimed technology was sufficiently concrete to qualify.

That outcome illustrates how AZA approaches patent disputes: representing patent holders against major defendants and carrying claims through federal appellate proceedings when district courts rule against clients. For Todd Mensing and AZA, the patent docket fits within the same trial-oriented model as the commercial and energy work.

A Breach of Contract Case in Federal Court

Port of Houston Authority v. Louis Dreyfus Commodities shows how the firm’s commercial contract practice looks in federal court. AZA represented the Port of Houston Authority in a breach of contract suit against a grain elevator operator in Case No. 4:19-cv-00746, before U.S. District Judge Lynn Hughes in the Southern District of Texas. Todd Mensing served as lead trial counsel for AZA throughout the proceeding.

The dispute turned on maintenance obligations under a long-term operating agreement with the grain elevator operator. After a jury trial, the Port of Houston received a $22.32 million verdict for breach of contract. Translating grain elevator maintenance standards and operator performance benchmarks into a damages framework the jury could quantify was a central challenge at trial.

Trade Secret Defense in the Energy Sector

Sentinel Integrity Solutions, Inc. v. Mistras Group, Inc. shows how Todd Mensing and AZA approach trade secret defense with a noncompete overlay. Sentinel, a competitor to Mistras in the industrial infrastructure inspection industry, sued Mistras and several of its employees for breach of non-competition agreements, theft of trade secrets, and tortious interference. Sentinel sought $9 million in damages.

AZA, with Mensing and John Zavitsanos as trial counsel, first defeated Sentinel’s efforts to obtain a temporary restraining order and preliminary injunction. When the case proceeded to a three-week jury trial, Sentinel received a no-liability finding on all claims and Mistras was awarded $750,000 in attorneys’ fees through trial, plus additional fees on appeal. The court issued a final judgment canceling Sentinel’s trademark and awarding Mistras its costs.

Sentinel also illustrates a pattern that appears across several AZA trade secret matters: clients accused of misappropriation who are competing lawfully. Noncompete enforcement combined with trade secret claims and trademark disputes is not unusual in the energy services sector, where personnel movement between competitors is common and former employers often reach for injunctive relief as a first response.

AZA’s employment docket extends beyond trade secret defense to affirmative executive claims. Mensing won a jury verdict for former executive Gaines Watkins against Input/Output Inc., a seismic data company, in an age discrimination suit. The energy industry context recurred: Watkins had worked in the seismic processing business, and the case turned on whether his departure was an unlawful termination rather than a legitimate reduction in force.

Across these practice areas, from energy and patents to contract disputes, trade secrets, and employment claims, the common thread is that Mensing and the firm have taken cases to verdict rather than settling before the jury could weigh in. Chambers’ description of the firm as home to “true courtroom lawyers” reflects a practice model that is trial-ready by design. Best Lawyers named AZA Tier 1 in Houston across six litigation categories in its most recent edition. What the case record shows, more than any ranking, is a firm that takes cases to the jury and wins a significant share of them.

Greene King pub chain to sell 150 sites amid ‘unprecedented’ costs

Published

Business Live

The pub chain is one of the UK’s largest and is also a major brewer, producing Greene King IPA, Old Speckled Hen and Belhaven beers

Greene King’s chief executive has attributed the firm’s decision to place 150 pubs up for sale to the “unprecedented” costs currently battering the hospitality industry.

The pub giant, one of Britain’s largest chains, unveiled plans to put up to 150 pubs on the chopping block in March, with chief executive Nick Mackenzie telling City AM the move was driven by escalating costs and “changing consumer behaviour”.

The company, which also brews Greene King IPA, Old Speckled Hen and Belhaven beers, intends to move 300 pubs into a separate unit, with half set to become leased or tenanted venues and the remaining half earmarked for sale.

Presenting the Chinese-owned pub firm’s annual results, Mackenzie said: “Long-term permanent reform from government is essential to ensure that unprecedented costs do not hold back the enormous potential of the sector.”

He told City AM the disposal of pubs formed part of a routine review of the Greene King estate, but that the chain chose to act ahead of the curve in response to a shifting economic climate, as reported by City AM.

He pointed the finger at “the cost environment that our industry has faced for the last five years, which is increased employment costs, increased cost of goods through events like the Ukraine war and now obviously what’s happening in Iran and the general economy”.

Mackenzie also turned his fire on business rates, after changes to the tax at last year’s Budget sent bills rocketing for thousands of pubs and left Chancellor Rachel Reeves forced into a £300m concession.

Labour committed to business rates reform in its manifesto but has yet to deliver wholesale change to the tax.

The pub boss said: “Business rates are unbalanced for our sector so we want the reform that was promised, and the fundamental reform is to rebalance the level of business rates taxation that our sector pays.”

Mackenzie, who sits on the government’s hospitality advisory board, said he is urging Labour to cut taxes on beer and reconsider its rollout of guaranteed hours rules for workers on zero-hour contracts.

Last month, several prominent trade bodies cautioned the government that its current proposals to clamp down on zero-hour contracts would cause youth unemployment to spike.

As consumer confidence slides to its lowest point in more than two years, Mackenzie said he is “worried” Brits may rein in non-essential spending such as trips to the pub.

Yet Mackenzie is hopeful the World Cup this summer will give Greene King’s revenues a lift, as the government commits to allowing pubs to stay open later. Greene King reported a 3.6 per cent rise in revenue to £2.5bn last year, posting an operating profit of £94m, a significant turnaround from a £16m loss the previous year.

The pub giant is currently constructing a new £40m brewery in Bury St Edmunds, which is due to open next year. The firm channelled £10m into its London estate this year, with notable sites including the Blue Posts in Soho and The Railway Tavern on Liverpool Street among those to benefit.

Greene King runs approximately 2,600 pubs across Britain, of which 840 are directly managed, with the remainder operating under franchise or tenancy arrangements.

Established by Benjamin Greene in Bury St Edmunds in 1799, Greene King was once listed on the London Stock Exchange before being taken private by Hong Kong billionaire Li Ka-Shing’s CK Asset Holdings in a £2.7bn deal in 2019.

Large and midcaps better placed than smallcaps in current phase: Shibani Sircar Kurian

Large and midcaps better placed than smallcaps in current phase: Shibani Sircar Kurian
Markets may be swinging between optimism and caution, but beneath the volatility lies a framework that seasoned investors are using to stay grounded. According to Shibani Sircar Kurian of Kotak AMC while uncertainty remains elevated due to global developments, valuations and historical trends provide a degree of comfort.

“So, yes, of course, we are navigating volatility at this point in time, and we do not know how long this volatility lasts… markets typically bottom out before the actual end of the war scenario.”

She pointed out that recoveries after crises are usually driven first by valuation re-rating before earnings catch up.

“When the markets start to recover, the initial leg… is led by multiples rerating, and then earnings have to flow through.”

On valuations, she noted that current levels are reasonable but not deeply attractive.


“Today… the Nifty is trading at about 19 times on a one-year forward, which is slightly below its long-term averages… valuations are reasonable… but not in deep value territory.”
Given this backdrop, the strategy remains cautious but opportunistic.“We will use market corrections to add to equities, but near-term volatility is something that we will have to navigate.”

Banking Sector Stands Out
Among sectors, banking has emerged as a clear outperformer this earnings season, with strong balance sheet growth and stable asset quality.

“The banking sector has seen fairly good numbers… both across balance sheet as well as earnings.”

Credit growth has picked up across segments, supporting expansion. “Credit growth has started to pick up… across industry as well as retail credit.”

Importantly, concerns around bad loans have not materialised.

“The fear of asset quality deterioration clearly has not played out… credit costs are well under control.” With interest rates stabilising, margins could also improve going ahead.

“We do expect… net interest margins also stabilise… and therefore there would likely be a pickup in earnings for FY27.” She added that valuations in the sector remain favourable. “Valuations are clearly on your side… banks, both private and PSU… we are positive on.”

Telecom: Improving Fundamentals
The telecom sector, after years of disruption, is seeing a more stable phase driven by consolidation and gradual tariff hikes.

“This has been a sector where consolidation has played out…” Profitability is improving as users shift to higher-paying plans.

“ARPU expansion has taken place at a gradual pace, and that is aiding profitability.” The outlook remains constructive for leading players.

“Some of the top players are fairly well placed… improvement in profitability is continuing.”

Private Banks Preferred
While both PSU and private banks look attractive, Kurian indicated a slight preference for private sector lenders. “We are overall positive on the banking sector; however… a slight preference for the private sector banks…”

The reason lies in valuation comfort relative to historical averages.

“The multiples are significantly below their long-term averages… the slight preference… is because of the valuation differential.”

Outlook: Stay Selective, Use Volatility
The broader message is clear—markets may remain volatile, but not directionless. With earnings expectations largely intact and valuations reasonable, corrections could offer opportunities for disciplined investors.

For now, the approach remains simple: stay selective, watch global cues closely, and use dips to gradually build exposure.
