Verdicts / Settlements (Case Results)
- Trademark Infringement Litigation – $1.3 Million Jury Verdict Reinstated on AppealUnder Sul Lee’s leadership, the firm represented I&I, a well-known hair extension company, in a federal trademark infringement case against a former business partner who continued selling products using I&I’s “EZ Pre-Stretched Braid” brand name after their license ended.The firm built a strong case demonstrating willful infringement, consumer confusion, and measurable business harm. After a multi-day federal trial, the jury awarded I&I $1.3 million in damages. When the trial court later reduced the award, Sul guided the firm’s appellate strategy — and the Fifth Circuit Court of Appeals reinstated the full $1.3 million verdict.This result showcases Sul’s leadership in high-stakes intellectual property litigation and her team’s ability to protect clients’ brands and innovations through meticulous trial preparation and appellate advocacy.
- Non-Compete Dispute – Favorable Pre-Litigation ResolutionSul Lee oversaw the firm’s representation of a group of former employees facing aggressive enforcement of a non-compete agreement by their former employer. The contract was overly broad and unenforceable under Texas law, restricting competition statewide without valid consideration.Under Sul’s guidance, the firm developed a targeted pre-suit strategy, issuing a detailed demand letter that cited key case law and exposed the employer’s overreach. The employer immediately ceased all enforcement efforts, allowing the clients to continue their new business operations freely.The matter was resolved entirely before litigation, demonstrating Sul’s ability to combine deep legal knowledge with practical, results-driven leadership in employment and business disputes.
- Franchise Dispute – $49,000 Claim Settled for $1,500 (Pre-Litigation Resolution)Under Sul Lee’s strategic oversight, the firm represented a Virginia-based franchisee seeking to terminate a Bodybar Pilates franchise agreement after being unable to open her studio. The franchisor demanded the full $49,000 initial franchise fee, despite never delivering operational support or training.Sul and her team leveraged Virginia’s franchise statutes — which require franchisors to confer actual value before collecting upfront fees — to challenge the demand. Through persistent negotiation, the team secured a full release of all obligations, reducing the payment from $49,000 to only $1,500. No litigation was required.This outcome showcases Sul’s practical and business-minded approach to resolving disputes efficiently, protecting small business owners from unfair franchise terms while avoiding costly legal battles.

Representative Clients
- Representative Client: I&I — Trademark Infringement LitigationCase Overview:Sul Lee Law Firm represented I&I, a leading hair extension company known for its “EZ Pre-Stretched Braid” brand, in a high-stakes federal trademark infringement case against a former business partner who continued selling knockoff products after their license was terminated.Result:After a full jury trial in the Northern District of Texas, attorney Dominique secured a $1.3 million verdict for I&I. Although the trial court initially reduced the damages, the Fifth Circuit Court of Appeals reinstated the full award, affirming the strength of the firm’s trial and appellate strategy.
- Representative Client: Bodybar Pilates Franchise DisputeCase Overview:Sul Lee Law Firm represented Lindsey Carter, a small business owner who entered into a Bodybar Pilates franchise agreement in Virginia. After encountering major difficulties securing a suitable location, the client was unable to open her studio. Despite this, the franchisor demanded the full $49,000 franchise fee, claiming entitlement under the contract — even though no services, training, or operational support had been provided.Result:Through strategic negotiation, attorney Dominique leveraged Virginia’s franchise laws, which require that franchisors provide actual value before collecting fees. By presenting a well-supported statutory argument and negotiating firmly, Dominique reduced the franchisor’s demand from $49,000 to just $1,500, fully terminating the franchise with no future liability. The matter was resolved entirely pre-litigation, saving the client significant time and expense.
- Representative Client: CGAR – Non-Compete / Employment DisputeCase Overview:Sul Lee Law Firm represented a group of former employees from a gold and silver sales company after their former employer attempted to enforce an overly broad non-compete agreement once they launched their own independent business. The agreement covered the entire state of Texas, had no clear time limit, and offered no additional consideration — making it legally vulnerable.Result:Through a single, decisive pre-litigation letter, attorney Dominique successfully dismantled the employer’s claims. The letter demonstrated that the non-compete violated Texas Business and Commerce Code §15.50 and lacked enforceability. Following receipt, the employer’s counsel ceased all enforcement efforts, allowing the clients to continue operating their business freely — without litigation or settlement.
