Trademark applications and registrations in Class 45 over the past 15 years.

Class 45 covers legal services, security services for the physical protection of tangible property and individuals, and personal and social services rendered by others to meet the needs of individuals. It is the final class in the Nice Classification system and one of the smaller service classes, though it covers several commercially significant service categories including legal practice, private investigation, and personal concierge services.

The class encompasses law firms, intellectual property services, alternative dispute resolution, security guard and alarm monitoring services, dating services, funeral services, personal shopping and styling services, astrology, baby sitting, and licensing of intellectual property. Top filing firms include LZ Legal Services, LegalForce RAPC, and Greenberg Traurig. Notably, LZ Legal Services — itself a legal services provider — leads filings in this class, illustrating the recursive nature of trademark practice: legal service providers protecting their own brands under the same class that covers their professional services.

Classification challenges in Class 45 often arise at the boundary with Class 42 and Class 36. Legal services are firmly in Class 45, but legal technology platforms (software for legal research or case management) are Class 42 for the software service and Class 9 for downloadable applications. Security guard services and physical surveillance belong in Class 45, but cybersecurity and digital security services fall under Class 42 — a distinction that has become increasingly important as security companies offer both physical and digital protection. Intellectual property licensing services are in Class 45, but financial services related to licensing revenue belong in Class 36. Social networking services can involve Class 45 for the personal and social service aspects, Class 38 for the communication platform, and Class 42 for the underlying technology.

Multi-class strategies for law firms typically pair Class 45 with Class 41 for legal education and CLE programs, Class 42 for legal technology platforms, and Class 35 for business consulting services offered alongside legal counsel. Security companies should file Class 45 for physical security alongside Class 42 for cybersecurity services and Class 9 for security hardware and software products. Online dating and social platforms require careful analysis across Classes 45, 38, 42, and potentially 41 for entertainment aspects of the service.
