Craig J. Mariam is an experienced litigation and trial attorney, practicing nationwide to address his clients’ needs wherever they may arise. With a substantial and unblemished federal and state jury and bench trial record under his belt and educational achievements and awards in science and mathematics, Craig's unique expertise contributes to his ability to effectively strategize and prepare an advanced, rational, winning theory in each case, as well as to convey the sometimes difficult language of expert witnesses for the benefit of his clients and the jury.

He graduated from the University of Texas at Austin with a degree in economics and an underlying tract in mathematics and computer engineering. He received his Juris Doctorate from Loyola Law School in Los Angeles and worked in-house in legal and business affairs at globally known companies before engaging in private practice. 

His areas of expertise include:

Commercial, Data Breach, and Technology Litigation (including Intellectual Property, Cyber Liability/Software, Defamation, and Entertainment)

Craig is a leading nationwide data breach litigator, having represented large-scale data privacy litigation in jurisdictions spanning the continent, including precedent-setting engagements. His team's successes include complete dismissals on both legal and factual grounds, as well as having masterminded creative, outside-the-box resolutions that allow his clients to focus more immediately on growing and maintaining their business value and public goodwill in light of the public nature of such breaches. Part and parcel to these matters, Craig is significantly engaged in administrative response and defense relative to governmental investigations or claims, including, for example, legislative subpoenas, Department of Justice investigations, and proceedings initiated by state Attorneys General.

He has also tried to verdict cases involving or related to the prosecution and defense of copyrights, trademarks, domain disputes, privacy rights, and defamation actions. He regularly represents individuals and entities including, for example, individuals involved in competitive professional services (such as brokers, advisors, or agents), producers, directors, writers, journalists, and artists involving such defamation-based claims and potential First Amendment-related defenses.

Craig has further tried and/or litigated to successful verdicts and judgments a substantial number of software breach and misappropriation matters and is at the forefront in terms of the legal aspects of emerging technology given his proficiency in mathematics and computer systems and his active litigation practice during a period of evolving and changing privacy and security risks in cyberspace, including potentially insecure mobile devices, cloud computing, virtualization, and other information technologies.

Class Action Defense Including Consumer Protection Statutes

Craig is heavily involved in class action litigation including, for example, nationwide and state class claims arising under consumer protection statutes and false advertising or unfair competition statutes, including, as just some examples, the Confidentiality of Medical Information Act (CMIA) and related PHI/PII data privacy claims, federal misbranding or labeling claims (i.e. OFPA or FFDCA), COPPA (Children’s Online Privacy Protection Act), the TCPA (Telephone Consumer Protection Act), FDCPA (Fair Debt Collection Practices Act), and ICRAA/FCRA (Investigative Consumer Reporting Agencies Act/Fair Credit Reporting Act). 

Directors & Officers and Securities Claims

He has successfully defended individual directors and officers – and corporate entities - in shareholder derivative and direct actions for alleged breach of fiduciary duties and related claims.  Many of these claims involve alleged securities violations on both a state and federal level. Craig has been involved in and has helped secure imaginative and creative resolutions on behalf of – and to the benefit of – corporate clients through “outside the box” negotiation skills and mediation efforts.
