In the Texas state courts, Mr. McManis has successfully obtained multiple TROs protecting against the theft of company information by departing employees and preventing confidential information from being used by his clients’ competitors. In trial, Mr. McManis has successfully secured both defense and plaintiff verdicts, including a take nothing verdict after a five-week trial in Harris County and also as a key member of teams that have won some of the largest patent infringement verdicts in the country in recent years.

    • The battle over lost profits damages in commercial litigation is contentious and can involve significant damages awards. Lost profits are often the most substantial aspect of the plaintiff's claim, one of the most challenging types of damages to prove, and are particularly susceptible to attack. When an injured business loses revenues, that business also avoids costs required to generate those revenues. These avoided costs must be deducted from lost sales to determine lost profits damages. However, experts often disagree on how to calculate these costs. Cost estimation is an integral part of a lost profits analysis. Attorneys must understand this cost analysis to determine what documents to request in discovery, as well as how to structure cross-examination questions for witnesses and experts to draw out the information essential for their expert to perform the required analysis. Listen as our panel of distinguished experts guides litigators on understanding cost behavior analysis and its impact on calculating lost profits damages. Our panel will discuss common methods for determining avoided costs as well as what information attorneys must be gathering during discovery to aid experts in conducting a cost analysis., Presenter, Lost Profits Damages: Cost Behavior Analysis, Calculation Methods, Strafford Publications, 2019
