Trademark Attorneys for Businesses, Founders, and Brands

Your trademark is more than a filing—it’s a business asset. We help clients at every stage: from clearance and registration to enforcement and litigation.

Whether you are launching a new brand, responding to a USPTO refusal, or dealing with infringement, we provide practical, litigation-informed guidance to protect your rights and position you for growth.

Trademark Strategy, Clearance, and Registration

A strong trademark starts before filing. We structure applications to maximize approval and long-term enforceability.

Our services include:

  • Comprehensive trademark search and clearance
  • USPTO federal trademark registration
  • California state trademark filings
  • Class selection and goods/services identification
  • Specimen strategy and application preparation
  • Portfolio management and monitoring
  • Renewals and maintenance filings

Every matter starts with a simple question: What do you want this brand to be able to do? We then align your trademark strategy with that answer.

USPTO Office Actions and Refusals

If your application has been refused, timing and strategy matter.

We regularly assist clients facing:

  • Likelihood of confusion with existing registrations
  • Descriptiveness or genericness issues
  • Specimen rejections
  • Identification of goods/services problems
  • Procedural or technical defects

We assess your position, explain realistic outcomes, and prepare targeted responses designed to overcome refusal or reposition your application.

Trademark Enforcement, Defense, and Litigation

Trademark rights only matter if they can be enforced.

We represent clients in:

  • Cease-and-desist letters (sending and responding)
  • Trademark infringement disputes
  • TTAB oppositions and cancellations
  • Federal trademark litigation (Southern District of California)
  • Online brand enforcement (Amazon, social media, domains)
  • UDRP domain disputes

We focus on leverage, not noise: clear demands, targeted relief, and a litigation posture that your counterparty and their counsel take seriously.

Avoid Costly DIY Trademark Mistakes

DIY filings often create problems that surface later—when enforcement matters most.

Common issues include:

  • Weak or descriptive marks
  • Incorrect class selection
  • Missed conflicts with existing marks
  • Defective specimens
  • Registrations that are difficult to enforce

We build filings that hold up under scrutiny, not just ones that get approved.

Who We Work With

We represent a broad range of San Diego clients:

  • Startups and emerging companies
  • SaaS and technology companies
  • E-commerce and consumer brands
  • Marketing and creative agencies
  • Influencers and personal brands
  • Professional service firms

Each engagement is tailored to your business stage and risk profile.

Why Wingert Grebing Instead of a Large IP Firm

San Diego has nationally recognized IP firms, but bigger isn’t always better. Large IP firms often bring layers, delays, and unnecessary cost.

We operate differently:

  • Direct access to experienced attorneys
  • Lean, efficient execution
  • Faster decision-making
  • Litigation-ready strategy from day one
  • Predictable, practical billing

We focus on the outcome, not process.

Common Trademark Questions | FAQs

Do I really need a federal trademark registration?

If you are investing in a name, logo, or brand in more than a narrow, local context, federal registration typically provides stronger, nationwide rights, public notice, and better enforcement tools.

How long does the trademark process take?

The USPTO examination process often runs several months before initial review, followed by publication and potential opposition. We set expectations early and monitor your application through each stage.

What if someone is already using a similar name?

We assess both legal risk and practical risk. That includes reviewing existing registrations, unregistered use, industry context, and your business plans before recommending enforcement or rebranding.

Can you take over an application I filed myself?

Yes. We frequently step in after an Office Action or when a self-filed application has stalled. We review the existing filing, identify issues, and either repair the current application or recommend a more strategic refiling.
