Conrad O’Brien defends class actions in a wide range of contexts, including securities, insurance, antitrust, consumer protection, property loss, and product liability claims. Our attorneys combine substantive expertise with a deep understanding of the unique problems raised by class action cases. We work with our clients to develop focused case plans, seek early resolution where possible, make every effort to defeat class certification, and assemble efficient trial teams that present complex issues simply and persuasively.


Notable Cases


  • Defended a publicly traded insurance company together with its officers and directors, in multiple shareholder class actions, filed in state and federal courts seeking to enjoin the company’s acquisition in a merger valued in excess of $220 million. Our team’s instrumental contributions to the defense team helped bring about a highly favorable global settlement that permitted the merger to close on schedule and without modification of the challenged terms.

  • Represented Progressive Insurance Company in a long-pending class action case in which a class of medical providers contended that Progressive must pay automobile accident personal injury claims within 30 days of receipt of completed standard claim forms or pay statutory interest on unpaid claims, even when Progressive had not yet completed its claims investigation. In 2003 the trial court accepted the plaintiffs’ position and certified the class. Conrad O’Brien took over the case after the trial court had certified the class, and in January 2014, the Pennsylvania Supreme Court reversed and decertified the class, effectively ending years of litigation in the insurer’s favor.

  • Obtained summary judgment for our client, Pennsylvania American Water Company, in a class action alleging $100 million of property loss from an industrial fire. The class asserted a unique claim that the water distribution system was improperly designed, causing a lack of water flow and pressure to extinguish the fire.

  • Achieved a series of wins for insurance company clients in three nationwide putative consumer class action lawsuits brought in New Mexico state court alleging breach of contract and failure to disclose premium charges. One suit was dismissed for forum non conveniens, the second suit was withdrawn in the face of threatened discovery into the putative class plaintiffs’ finances, and the third was settled for minimal attorney’s fees and a nominal settlement value based on a New Mexico–only class.

The client contended that the vessels were improperly welded, requiring extensive testing of the vessels deployed throughout the world.

  • Represented a general contractor seeking insurance coverage for wrongful death and personal injury claims arising out of a serious construction accident at the Tropicana Casino in New Jersey.

These rulings were instrumental in settling more than 30 cases that had been filed concerning the accident.

Contract Litigation

Contract disputes are a major focus of Conrad O’Brien’s complex commercial litigation practice. Our experience ranges from litigating significant contract matters for our Fortune 500 clients to resolving a wide range of contract issues on behalf of the region’s entrepreneurial businesses.


Notable Cases

  • Represented two firms in the commercial real estate financing industry in three separate actions arising out of a contract for the sale to a developer of a parcel of real property in Center City Philadelphia. The litigation was first brought after the parties failed to reach a written extension for the developer to close on the property.  After the developer failed to close, our client filed an action seeking a declaration that the developer was in default of the agreement and that our client was entitled to liquidated damages. The parties engaged in extensive discovery and motion practice. With motions for summary judgment pending, the parties were able to reach a settlement which permitted the developer to close on the property.  

  • Represented Hewlett-Packard and HP Financial Services Company in the U.S. District Court for the Eastern District of Pennsylvania in a breach of contract and warranty action arising out of the installation of various storage-related products and software. After initial motion practice, plaintiffs voluntarily dismissed HP Financial Services Company, and the case successfully settled before HP incurred significant discovery costs.

  • Represented IBM in a lawsuit brought by a potential subcontractor under a “teaming agreement” entered into in connection with a contract between IBM and the Department of Defense. After the district court granted IBM’s motion to dismiss, the Third Circuit remanded one claim for further proceedings. On remand, the district court granted IBM’s renewed motion to dismiss. That decision was upheld on appeal.

  • Won a motion to dismiss for Lorillard Tobacco Company in a multimillion-dollar breach of contract claim. The district court found that the parties’ distributorship contract was a contract of indefinite duration and therefore terminable at-will under Pennsylvania’s Uniform Commercial Code.

  • Defended an outdoor advertising developer in a suit alleging, inter alia, fraud and misrepresentation in connection with an outdoor advertising transaction. The New Jersey state court entered judgment on the merits in favor of our client on all claims.

  • Represented the principal of a capital investment firm in a tortious interference with contract suit in federal court in the Eastern District of Pennsylvania. We obtained a voluntary dismissal of claims against our client that had been pending for four years.

The trial court granted defendants’ motion for summary judgment on all claims. Pending the plaintiffs’ appeal to the Second Circuit, a favorable settlement was reached.

  • Achieved dismissal of a class action on behalf of Progressive where a class of Pennsylvania massage therapists sought to recover insurance benefits. The case was dismissed on the basis that the plaintiffs were required to hold the equivalent of a physical therapist’s license in order to seek insurance benefits. That ruling was affirmed on appeal.

Conrad O’Brien’s attorneys serve as or represent court-appointed federal and state receivers in actions brought by the Securities and Exchange Commission (SEC), Federal Trade Commission (FTC), and other government enforcement agencies to recover assets used to compensate nationwide victims of Ponzi schemes and other frauds.


In these highly complex cases, the court-appointed equity receiver is charged by the court to marshal, pursue, preserve, and maximize the recovery of receivership assets. Often this involves significant third-party litigation, clawback procedures, and court-approved settlements.


Notable Cases


  • Conrad O’Brien attorney was the court-appointed receiver, with Conrad O’Brien acting as lead counsel, in an SEC enforcement action against the operator of a Ponzi-like scheme who stole tens of millions of dollars from investors in hedge funds he managed. This matter involved several litigations and claims against dozens of persons and entities, including but not limited to company insiders, investors, professional firms, brokers, nonprofit organizations, and political organizations. Through distributions of much of the recovered funds, we have recovered and restored to innocent investors more than 80% of the losses suffered. The receivership was recently closed and converted to a liquidating trust with Conrad O’Brien attorney serving as the liquidating trustee for certain illiquid assets that continue to be maintained for the potential benefit of victims.

  • Conrad O’Brien’s Patricia Hamill serves as the court-appointed receiver, with Conrad O’Brien attorneys acting as lead counsel, in an FTC action against entities in the technical support services industry alleged to have misrepresented their services to tens of thousands of customers who paid them at least $17.9 million. As receiver, Patricia was tasked with taking control of the business operations of corporate defendants, securing two separate physical locations, several virtual offices, and numerous financial accounts, websites, and phone numbers. She continues to preserve and administer the assets of the receivership estate.

  • Represented a federally-appointed receiver in an enforcement action brought by the federal government in the Eastern District of Pennsylvania against a third-party payment processing company and its principals (who were alleged to have facilitated a nationwide fraudulent telemarketing scheme). Conrad O’Brien attorneys recovered over $1 million from a national bank to fund a Consumer Restitution Program for victims of the fraud. Our efforts against the bank uncovered information that launched further government action, resulting in the recovery of more than $150 million to fund a full restitution program for the victims.

  • Conrad O’Brien’s Patricia Hamill served as the court-appointed receiver, with Conrad O’Brien attorneys acting as lead counsel, in an action brought by the FTC in the Western District of New York against entities and individuals in the debt collections industry found to be conducting business in violation of the Fair Debt Collections Practices Act (FDCPA) and related state statutes. The FTC determined that in excess of $8 million was collected from consumers using unlawful practices. Patricia and her counsel worked in conjunction with the government to assess the nature of the defendants’ practices; halt all collection activities; manage the defendants’ remaining operations; handle a variety of employment, payroll, and tax issues; collect, analyze, and respond to a variety of claims made against the defendants; and worked with forensic accountants to recover and maximize the assets of the receivership.

  • Represented the receiver in an enforcement action brought by the FTC in the Northern District of Illinois against a number of related telemarketing businesses alleged to have been involved in the marketing of fraudulent credit cards. The case settled with the defendant business operators for more than $7.5 million, providing nearly 100% restitution to the victims.

Notable Cases


  • Represented a former officer of a medical equipment financing company in proceedings that arose after the company filed for bankruptcy. The proceedings included lawsuits by the bankruptcy trustee, shareholders, bondholders and financial institutions, and investigations by the SEC and the Department of Justice. The DOJ declined prosecution and, after a lengthy Wells process, the SEC declined to pursue an enforcement action against our client. Two of the civil cases were settled with a minimal contribution from our client, and class action shareholder plaintiffs agreed voluntarily to dismiss our client with no monetary settlement.

  • Represented a former interim chief financial officer for a startup company that was alleged to have operated the largest green-energy Ponzi scheme in the United States. A class action and a parallel civil action filed by the receiver for the startup company asserted various claims against the former CFO along with other professionals associated with the company. In addition to defending against those actions, Conrad O’Brien also assisted the former CFO in a coverage dispute with multiple insurers. Conrad O’Brien secured coverage and obtained a global settlement agreement resolving both lawsuits without any payments from the former interim CFO.
