REPRESENTATIVE WORK
Mr. Bai has significant experiences in patent litigation representing both Plaintiffs and Defendants across a variety of forums and technologies. Some examples of his success include:
- Currently representing Anonymous Media Research Holdings, LLC in the enforcement of its patents covering automatic content recognition data processing technology against Smart TV manufacturers’ digital advertising business lines. Mr. Bai recently helped Anonymous Media win a $78.5 million verdict against global electronics giant Samsung. He was instrumental in developing, and presenting at trial, the plaintiff’s damage model. The jury awarded Anonymous Media’s damage ask to the dollar.
- Successfully helped enforce Standard Essential Patents (SEPs) that cover high-definition speech coding, both in the US and abroad, where his clients recovered over $250 million in licenses and settlements. Along the way, he helped an AZA trial team win a $9 million jury verdict with a willful infringement finding against Motorola. He was also instrumental in managing an SEP enforcement campaign in China, where his client defeated dozens of validity challenges filed by various Chinese smartphone giants, and secured one of the largest licenses obtained in Chinese litigation by a U.S.-based patent assertion entity.
- Successfully represented numerous additional patent owners in enforcement of patent rights in courts across the United States. The technology areas include simulated app development environments, electronic fracking equipment, mobile activity monitoring and tracking, Bluetooth communication modules, and computer memory management. He has helped his clients secure over $100 million in licenses and settlements after winning significant claim construction, summary judgment, administrative validity challenges, and other pretrial victories.
- Successfully defended numerous clients from claims of patent infringement. He recently helped an electronics distributor secure a pre-Markman stay of an infringement claim brought by a competitor after institution of post-grant reviews. He also helped a leading energy services provider secure a walkaway settlement after winning extremely favorable claim construction rulings which ultimately resulted in the plaintiff stipulating to non-infringement.
Mr. Bai also has significant experiences in trade secrets litigation, where examples of his success include:
- Successfully represented two oilfield service companies in a theft of trade secret, fraud, and breach of fiduciary duties case related to fracking proppant storage and transport technology. Plaintiffs brought suit against numerous defendants. AZA initially represented one of the named defendants. After AZA cut down the vast majority of Plaintiffs’ claims via pretrial motions, Plaintiffs non-suited AZA’s first client on the eve of a summary judgment hearing. Then, two additional co-defendants hired AZA to defend them in the same case, replacing prior counsel. AZA similarly cut down many of Plaintiff’s claims via pretrial motions, and developed a novel federal jurisdiction theory to remove the case to federal court. Shortly after, AZA’s clients were dismissed with extremely favorable settlements (approximately 1% of Plaintiffs’ damages ask). Mr. Bai developed the defense strategy in the case, defended and took all key depositions, and briefed and argued all major hearings.
- Successfully represented a Houston-based directional drilling company against a competitor and a former vendor over theft of trade secrets and copyright infringement involving motor transmission technology. His client secured a highly favorable monetary settlement and an agreed, publicly-filed, permanent injunction.
- Successfully represented an international supplier of managed pressure drilling equipment against a competitor and former employees in a theft of trade secrets case involving rotating control devices technology. The case settled on highly favorable terms for his client after the trial court entered an injunction and denied defendants’ motion to dismiss.
- Successfully represented an international oilfield services company against a former employee in a theft of trade secrets case involving downhole electronic tools. The case settled on the eve of trial with his client fully recovering the rights to all disputed trade secret technology at issue.
Mr. Bai has also successfully represented clients across a variety of other types of civil, commercial litigation, where his experiences have included:
- Currently representing energy major Chevron in a substantial, nine-figure environmental contamination case brought by a West Texas landowner who claim that over 100 legacy Chevron wells on her property have allegedly leaked downhole and at surface. Mr. Bai has led the development of the technical aspects of this scientifically complex matter, taken and defended numerous key fact and expert witness depositions, and briefed and argued many significant motions. He won a major Temporary Injunction Hearing where he cross-examined plaintiff’s lead petroleum engineering expert and direct-examined Chevron’s well plugging superintendent and engineer. He followed up that victory by briefing and arguing several pretrial motions that resulted in the exclusion of the plaintiff’s largest damage model in the case, as well as several key liability theories. The case is set for trial in January of 2026.
- Currently representing patients in class action proceedings around the country involving the misuse of tracking pixel technology on hospital websites and patient portals, which have resulted in the mass disclosure of confidential health communications to advertisers such as Google and Facebook. Mr. Bai has helped achieve significant successes for patient classes in courts across the country, including defeating removal attempts, winning interlocutory appeals, beating motions to dismiss, and achieving class certification and favorable settlements. To date, he has helped numerous patient classes obtain significant monetary relief worth substantial 8 and 9 figures, as well as exhaustive injunctive relief to eliminate the use of the offending tracking pixel technology.
- Won a no-liability jury verdict as first-chair, trial counsel for a Houston-area radiology services provider in a business fraud dispute. A former competitor-turned-employee brought suit after his termination, and alleged that he was fraudulently induced by Mr. Bai’s client into signing away his prior company’s hospital service contract and agreeing to a merger. Plaintiff sought $1.2 million in actual damages as well as significant punitive damages. After a 4-day trial, the jury deliberated for less than an hour before returning a verdict of no fraud in favor of HRA.
- Successfully represented a variety of companies and individuals in contractual and business tort disputes, such as breaches of insurance contracts, partnership or LLC corporate divorces, bankruptcy adversarial proceedings, fraud and fraudulent transfer claims, employment discrimination fights, and numerous other subject matters. Along the way, Mr. Bai has repeatedly helped his clients win favorable outcomes, including dismissals, summary judgments, and awards of attorneys’ fees and costs.
