Trademark Infringement Attorney in Colorado

Engineering Backgrounds. Two Decades of IP Practice. Trademark Counsel Built Around Your Business.

A trademark does more than label your product. It signals ownership, builds consumer trust, and becomes one of your company’s most defensible assets. When someone else trades on your mark, the harm is real: lost customers, diluted brand value, and legal costs that compound the longer you wait. At Martensen IP, we handle trademark registration, enforcement, and defense for businesses and individuals across Colorado and nationwide, working from our Colorado Springs office.

Michael Martensen has practiced IP law since 1997, bringing backgrounds in military program management, multiple engineering degrees, and an MBA to every matter he handles. Every attorney at the firm carries more than two decades of legal experience alongside engineering and business qualifications. That combination lets us connect trademark strategy to your actual business goals, not just the legal outcome in isolation. For Colorado companies in technology, aerospace, defense contracting, craft brewing, and outdoor recreation, that kind of integrated thinking matters.

Trademark Protection Services We Provide

We serve clients nationwide from our Colorado Springs office. Our work covers trademark searches to confirm proposed marks are available and non-infringing, through the full registration process, to ongoing protection once a mark is secured. Services for businesses and individuals include:

• Trademark clearance searches: Identifying existing marks that could block registration or expose your brand to an infringement claim before you invest in it
• Application preparation and filing: Drafting accurate, complete applications for the USPTO or Colorado’s Secretary of State, depending on the scope of protection you need
• Marketplace monitoring: Watching for unauthorized uses of your mark so potential infringement is caught early
• Portfolio management and renewals: Advising on deadlines, assignments, and amendments to keep trademark rights current as your business grows
• Infringement response: Sending cease-and-desist letters, negotiating resolutions, or representing clients in litigation when necessary

We also identify legal risks specific to Colorado’s business climate, including regional registration requirements and disputes with local competitors. Our attorneys monitor regulatory and market trends affecting Colorado companies and adapt our guidance accordingly.

Strategic Trademark Registration & Management

Trademarks include words, designs, phrases, symbols, or combinations that distinguish your business’s offerings from others in the market. Federal registration with the USPTO provides nationwide protection, legal presumption of ownership and validity, access to stronger damages remedies in infringement cases, and the ability to record your mark with U.S. Customs and Border Protection. State registration through the Colorado Secretary of State offers rights within Colorado under different requirements and scope. Which path fits your situation, or whether both make sense, is one of the first questions we work through with clients.

We guide clients through every stage of registration, starting with a thorough clearance search and risk assessment. Because requirements and timelines differ between the USPTO and Colorado’s Secretary of State, we explain both processes and can help clients avoid setbacks before they arise. For startups and established organizations alike, we structure the filing process around branding and growth goals rather than just moving paperwork. As companies expand, acquire, or rebrand, we advise on renewals, assignments, and amendments to keep trademark rights current. A protected trademark can also work alongside a patent portfolio to increase the overall value of your business.

Trademark Infringement in Colorado: Enforcement & Defense

Trademark infringement occurs when an unauthorized party uses a mark so similar to a registered mark that it’s likely to cause consumer confusion. Colorado courts evaluating infringement apply a multi-factor analysis that examines the similarity of the marks in appearance, sound, and meaning; the relatedness of the goods or services; evidence of actual consumer confusion; the strength of the original mark; the intent of the alleged infringer; and the degree of care exercised by purchasers, among other considerations. That standard applies whether you’re claiming infringement or defending against one.

Enforcement Options & Available Remedies

Colorado’s growth sectors, including technology, aerospace, defense contracting, craft brewing, and outdoor recreation, create frequent brand-imitation scenarios. Acting promptly when infringement is suspected helps preserve available remedies and limits further brand damage. Those remedies can include injunctive relief to stop the infringing use, monetary damages, disgorgement of the infringer’s profits, and, in some cases, recovery of attorneys’ fees. Defenses to infringement claims include challenging the validity of the mark, asserting fair use, or demonstrating no likelihood of confusion.

Michael Martensen has participated in all aspects of trademark and trade secret litigation, including both enforcement and defense matters. On the enforcement side, we pursue cease-and-desist letters, negotiated settlements, and litigation in the U.S. District Court for the District of Colorado or Colorado state courts. We also represent businesses defending against infringement accusations, applying the same analytical depth to assess the strength of a claim and identify the most appropriate path forward. Our attorneys draw on decades of Colorado practice and multidisciplinary backgrounds to help clients make informed decisions at every stage.

Frequently Asked Questions

What Should I Do If I Suspect Someone Is Infringing My Trademark?

Document the unauthorized use as thoroughly as possible, including dates, screenshots, product packaging, and any consumer-facing materials showing the infringing mark. Then consult a trademark infringement attorney in Colorado promptly. Acting quickly helps preserve your available remedies and prevents the infringing use from becoming entrenched in the market.

Which Courts Handle Trademark Disputes in Colorado?

The U.S. District Court for the District of Colorado typically hears cases involving federally registered trademarks or disputes that cross state lines. Disputes involving state-level marks registered with the Colorado Secretary of State may be handled in Colorado state courts. The Trademark Trial and Appeal Board (TTAB) handles opposition and cancellation proceedings before the USPTO, which can also be a venue for challenging or defending a mark before litigation begins.

How Long Does Resolving a Trademark Dispute Usually Take?

It depends on the complexity of the dispute and both parties’ willingness to negotiate. Some matters may resolve within weeks through a cease-and-desist letter or a negotiated settlement. Cases that proceed to litigation in federal court can extend for several months or significantly longer. We work to assess early whether a negotiated resolution is realistic so clients can plan accordingly.
