REPRESENTATION DISCLOSURE. Sul Lee Law Firm represents both plaintiffs and defendants across its business and commercial litigation practice, depending on the engagement.

Sul Lee Law Firm: The Dallas Business Litigation Attorney Firm That Turned a Reduced Verdict Into a Full Fifth Circuit Win

Sul Lee Law Firm is a Dallas business litigation attorney practice founded by a Korean-American entrepreneur-turned-lawyer — one whose team didn’t just win a $1.3 million jury verdict for a client, but fought a trial court’s reduction of that award all the way to a full reinstatement at the Fifth Circuit Court of Appeals.

Sul Lee Law Firm — Dallas Business Litigation Attorney At a Glance

Sources: sulleelaw.com (firm website), Super Lawyers, D Magazine, Justia. Compiled August 2026.

Origin: From Entrepreneurship to the Courtroom

Sul Lee started her Dallas law firm in 2013 to combine her interest in entrepreneurship with legal practice, focused specifically on helping small and medium-sized businesses navigate legal challenges. Fluent in Korean and English, she has built the firm around serving underserved client bases — particularly Asian-American and international business owners establishing a Texas presence — combining cultural fluency with Texas business law knowledge. She has been registered to practice before the U.S. Patent and Trademark Office since 2010, is a certified New York State Court Interpreter for Korean-English, and holds leadership roles in the Dallas Korean and Asian business communities, including having served as President of the Dallas Asian Chamber of Commerce (2019) and as an appointed legal advisor to the Dallas Korea Consular Office (2022–2023).

The firm’s litigation practice is led day-to-day by attorney Dominique Williams, whose most significant documented result is independently verifiable through the federal court record: representing I&I, a hair extension company known for its “EZ Pre-Stretched Braid” brand, in a trademark infringement case against a former business partner who continued selling knockoff products after their license was terminated. Following a full jury trial in the Northern District of Texas, Williams secured a $1.3 million verdict. The trial court initially reduced the damages award, but the Fifth Circuit Court of Appeals reinstated the full verdict on appeal — affirming the firm’s trial and appellate strategy at one of the country’s higher federal appellate courts.

Where the Firm Concentrates

The firm practices business and commercial litigation, corporate law, intellectual property (trademark and copyright, including USPTO and Copyright Office proceedings), employment litigation, franchise disputes, and commercial real estate law. As the disclosure above notes, the firm represents both plaintiffs and defendants across its litigation matters. A representative franchise dispute involved Lindsey Carter, a small business owner who entered a Bodybar Pilates franchise agreement in Virginia — illustrating the firm’s reach into disputes beyond Texas borders when a Texas-based client is involved. Readers comparing options can see how this profile fits alongside other Business & Corporate Litigation attorneys covered on Awesome Attorneys.

Notable Work

The I&I trademark verdict — a $1.3 million jury award reinstated in full by the Fifth Circuit after a trial court reduction — is the firm’s clearest, most independently verifiable litigation result, since Fifth Circuit decisions are published, reported opinions searchable in standard legal databases rather than relying solely on the firm’s own reporting. The firm also reports a favorable pre-litigation resolution for a group of former employees facing a non-compete dispute; that result, like most pre-litigation settlements, was not independently verified against court records for this profile, since settled or resolved-before-filing matters typically don’t generate a public docket. As with any litigation result, outcomes are case-specific and past results do not guarantee or predict a similar outcome in any future matter.

Client Voice

Awesome Attorneys did not locate a substantial volume of independently-verifiable, individually attributed client reviews for this firm at the time of research — the firm’s public marketing centers on case results and Sul Lee’s community leadership credentials rather than an aggregated review page. This gap is noted directly rather than papered over; prospective clients should ask the firm directly for references appropriate to their matter.

Beyond the Courtroom

Sul Lee’s community involvement is extensive and specifically tied to Dallas’s Asian and Korean business communities: Board Member of the Greater Dallas Asian Chamber of Commerce, Vice President of the Dallas Korean Chamber of Commerce, Vice President of the Korean Society of Dallas, past President of the Dallas Asian Chamber of Commerce (2019), and a 2016 Goldman Sachs 10,000 Small Businesses Scholar. Her 2022–2023 appointment as official legal advisor to the Dallas Korea Consular Office is a distinctive credential — a quasi-governmental advisory role tied directly to her bilingual, cross-cultural legal practice, not something available to most business litigators.

Recognition

Sul Lee and Dominique Williams’s Super Lawyers selections are peer-nomination-based. The firm’s strongest objective credential is the Fifth Circuit’s published reinstatement of the I&I verdict — an independently verifiable appellate result rather than a peer-nomination award or self-reported case summary. Awesome Attorneys did not locate additional third-party rankings (Chambers, Best Lawyers) for this firm at the time of research; Sul Lee’s community leadership roles (Chamber of Commerce presidency, consular office appointment) are civic and quasi-governmental recognitions rather than legal-practice-specific credentials.

Texas Legal Backdrop

Readers considering Texas business litigation should understand a few structural rules, presented as general information and not legal advice. Breach of contract claims in Texas generally carry a four-year statute of limitations (Tex. Civ. Prac. & Rem. Code § 16.004). Trademark infringement claims — relevant to the firm’s I&I result — typically arise under the federal Lanham Act, which carries its own body of case law on damages and injunctive relief distinct from Texas state law, though Texas also has its own trademark statute (Tex. Bus. & Com. Code ch. 16). Franchise disputes in Texas may implicate the Texas Business Opportunity Act and, depending on the franchise agreement’s terms, federal franchise disclosure requirements as well. Texas also has a specialized Business Court, created by recent legislation, that now handles certain complex commercial disputes above a jurisdictional threshold.

Awesome Attorneys Assessment

Sul Lee Law Firm’s differentiator is a genuine combination: an independently verified Fifth Circuit appellate win in trademark litigation, paired with founder Sul Lee’s deep, documented ties to Dallas’s Asian and international business community and her USPTO registration. For an Asian-American or international business owner establishing or defending a presence in Texas — or any business facing a trademark or IP-adjacent commercial dispute — that combination of appellate-verified litigation skill and cultural/linguistic fluency is a genuine differentiator.

The honest trade-off is public review depth: Awesome Attorneys could not locate a substantial independent client review record for this firm, which is a real gap relative to some competitors profiled in this category who have more extensive public testimonial pages. Prospective clients should ask directly for references, particularly for matters outside the firm’s most publicly documented IP litigation strength.
