Welcome back to our USPTO Trademark Classes Blog Series, where we break down each trademark class to help businesses properly categorize and protect their brands.
In this final installment, we’re covering Trademark Class 45, which includes legal, security, personal, and social services. If your business offers law-related services, personal concierge help, security or safety support, or lifestyle services, this class may be the right fit for your trademark.
If you’ve ever asked, “Can I trademark my law firm’s name?” or “What class covers private investigation or lifestyle coaching?”, this guide will help clarify whether this classification is appropriate for your brand.
What is Trademark Class 45?
Trademark Class 45 includes services that provide legal, personal, or social support, particularly those involving individual needs, safety, or rights. It is commonly used by attorneys, personal security firms, online safety services, and lifestyle management providers.
Some examples of services that might fall under Trademark Class 45 include:
Legal services and law firms
Trademark and intellectual property representation
Notary and legal document filing services
Private investigation and surveillance
Security guard and personal protection services
Background checks and identity verification
Personal concierge or errand-running services
Dating and relationship services
Funeral planning and spiritual counseling
If your business supports people’s legal, social, or personal needs, Trademark Class 45 is likely the appropriate classification.
Why Trademark Class 45 Matters for Your Business
Registering a trademark under Class 45 helps protect your brand in industries where trust, privacy, and professionalism are paramount. Here’s why filing in this class might be important:
Prevents confusion with other service providers – Legal and personal services often operate in overlapping geographic or online spaces. A trademark ensures your brand identity stands out.
Reinforces client trust and confidentiality – In high-trust sectors like law or personal security, a registered trademark adds legitimacy.
Supports business expansion – Whether you’re launching additional locations, services, or digital platforms, trademark protection ensures consistency.
Enables you to license, franchise, or collaborate – If you're developing branded tools or growing your practice, a trademark is a valuable asset.
Examples of Trademarks in Class 45
Many law firms, security providers, and concierge services register their trademarks in Class 45. Here are a few examples:
LegalZoom® – For online legal services and document preparation
ADT® – Registered for home security and personal protection services
Rocket Lawyer® – Covers virtual legal services and document generation
These companies use Class 45 protection to secure their names, service models, and digital tools used to deliver legal and personal support.
Do You Need a Trademark Search Before Filing in Class 45?
Yes—a trademark search is strongly recommended, especially in Class 45, where many businesses use common terms like “law group,” “investigations,” or “security solutions.” Conflicts with existing trademarks can delay or block your application.
At Brand Diplomacy, we conduct full trademark clearance searches to help you proceed with confidence and avoid unnecessary obstacles.
How to Determine if Class 45 is Right for Your Trademark
If you’re unsure whether Trademark Class 45 is the correct category for your services, consider the following:
Does your business involve legal, personal, or security services?
If yes, Class 45 likely applies.
Do your services focus on individual clients’ needs, safety, or well-being?
This includes anything from legal advice to home monitoring.
Does your business offer additional tools, software, or merchandise?
You may also need:
Class 9 for legal tech platforms or security software
Class 35 for business consulting or online directories
Class 16 for printed materials or legal templates
If your brand spans multiple offerings, consider filing in more than one class for full protection.
