10 Best Trademark Lawyers in Denver, CO

This guide compares the best trademark lawyers in Denver, CO, featuring 10 law firms with Denver offices that handle trademark work, from clearance searches and USPTO applications to Trademark Trial and Appeal Board (TTAB) proceedings, enforcement, and portfolio management. Firms were evaluated based on three factors: trademark-specific credentials, such as World Trademark Review 1000 rankings and Best Lawyers recognition; the depth of a dedicated trademark practice compared with a general practice that lists trademarks as one service among many; and the range of services offered, from a single filing to a multi-country portfolio.

When comparing options, three practical questions matter most. First, does the firm handle the full lifecycle of a mark, including responding to USPTO Office Actions and defending oppositions and cancellations, or only filings? Second, does the firm’s size and billing model fit your brand, since a startup filing one application has different needs than a company managing marks in dozens of countries? Third, does the team regularly work in your industry?

Quick View: Top 3 Trademark Law Firms in Denver, CO

Here is the list of best trademark lawyers in Denver, CO:

1. Four Reasons Legal

• Attorney/Key Figure: Steve Zemanick, Founding Attorney and Principal
• Headquarters: 8074 E 34th Avenue, Denver, CO 80238
• Phone: (720) 937-6599
• Website: fourreasonslegal.com
• Practice Areas: Trademark clearance, registration, portfolio management, enforcement, oppositions and cancellations, cease and desist letters; copyright; design patents; domain name disputes; intellectual property transactions
• Firm Size: Solo IP practice with direct attorney access, more than 15 years of IP experience
• Practice Area Page: Denver Trademark Lawyer
• Social Profiles: Facebook

About The Firm: Steve Zemanick founded Four Reasons Legal after more than 15 years practicing intellectual property law, including time as a senior associate at Dorsey & Whitney from 2006 to 2014. He is a registered patent attorney with the USPTO, is admitted to the bars of Colorado and Massachusetts, and has been a member of the International Trademark Association since 2006. He was named a Colorado Super Lawyers Rising Star in intellectual property in 2010.

The firm is built around one-on-one trademark service: availability searches and clearance, federal registration, portfolio management, enforcement, and representation in disputes before the USPTO and the Trademark Trial and Appeal Board. Clients work directly with Zemanick rather than a rotating team, and the firm also assists with foreign trademark filings through the Madrid Protocol. Its clients span retail and consumer goods, software, health care, hospitality, and publishing, and long-standing clients describe him as responsive and straightforward on billing.

2. Holland & Hart

• Headquarters: 555 17th Street, Suite 3200, Denver, CO 80202
• Phone: (303) 295-8000
• Website: hollandhart.com
• Practice Areas: Global trademark brand management, intellectual property, IP litigation, IP and technology transactions, patent prosecution, data privacy, sponsorships and promotion transactions, corporate, and more
• Firm Size: Large, 500+ lawyers across multiple Western offices

About The Firm: Holland & Hart was founded in 1947 and is headquartered in Denver. Its trademark group earned the top “Gold Band” ranking for Colorado in the 2026 World Trademark Review 1000, the thirteenth year in a row, and the firm reports that 15 of its attorneys were individually ranked nationally and regionally in that edition. It was also ranked in the Bronze Band nationally for both enforcement and litigation and for prosecution and strategy.

The team covers clearance, prosecution, enforcement, and domain name protection, and it advises on online marketplace monitoring and anti-counterfeiting. That mix suits brand owners who sell through e-commerce platforms and need ongoing watch and takedown programs rather than a one-time filing. As a large full-service firm, it is built around business clients with continuing brand needs, so a founder with a single application may find a smaller shop a closer fit.

3. Faegre Drinker Biddle & Reath

• Attorney/Key Figure: Emily A. Bayton, Partner
• Headquarters: 1144 15th Street, Suite 3400, Denver, CO 80202
• Phone: +1 303 607 3500 (Emily Bayton direct: +1 303 607 3665)
• Website: faegredrinker.com
• Practice Areas: Trademark, copyright, advertising and media; intellectual property; technology transactions and licensing
• Firm Size: Large, national firm with Denver and Boulder offices

About The Firm: Emily Bayton leads trademark work in Faegre Drinker’s Denver office after 17 years as a partner at Lewis Roca Rothgerber Christie, where she co-chaired the intellectual property group. She has almost two decades of experience in trademark, copyright, rights of publicity, domain name, and advertising matters. She has been listed in the World Trademark Review 1000 for Colorado every year from 2016 to 2026 and in Best Lawyers for trademark law from 2023 to 2027.

Her practice is notable for its industry focus: sports and outdoor recreation and consumer products, which fit Denver’s brand landscape. She regularly appears in TTAB opposition and cancellation proceedings and in domain name disputes under the UDRP, and she builds enforcement programs for clients after reviewing whether their portfolios have the right worldwide coverage.

4. Kilpatrick Townsend & Stockton

• Headquarters: 1400 Wewatta Street, Suite 600, Denver, CO 80202 (national firm headquartered in Atlanta)
• Phone: (303) 571-4000
• Website: ktslaw.com
• Practice Areas: Trademark and copyright, intellectual property, technology, and more
• Firm Size: Large, with offices in eight of the ten largest U.S. metro areas

About The Firm: Kilpatrick Townsend has built a national reputation in trademark law. In the 2026 World Trademark Review 1000, the firm reported gold-level recognition for its U.S. national trademark practice and 38 individually ranked U.S. attorneys, the most of any firm, with Colorado among the jurisdictions where it was recognized.

The Denver office houses a Trademark and Copyright team within the firm’s Intellectual Property Department, and its Denver trademark attorneys have worked on search and clearance and global portfolio management for clients in technology, media, entertainment, and food and beverage. The trade-off is scale: this is a large national platform, which brings deep resources for multi-jurisdiction programs but can be more than a small business with a single mark needs.

5. Quarles & Brady

• Attorney/Key Figures: Ian Saffer and Kate Bohmann, Intellectual Property Partners
• Headquarters: Denver, CO office (national firm headquartered in Milwaukee)
• Website: quarles.com
• Practice Areas: Trademark and copyright counseling, IP litigation, trademark portfolio management, patent, and more
• Firm Size: Large, about 520 attorneys nationally; Denver office formed from the 29-person Adsero IP boutique

About The Firm: Quarles opened its Denver office on March 1, 2023, by combining with Adsero IP, a Denver intellectual property firm founded in 1994. Ian Saffer, who led Adsero, has been ranked in the World Trademark Review 1000 for Colorado from 2014 and appears again in the 2026 edition. He reports litigating roughly 200 matters before the TTAB and federal courts and managing trademark portfolios of thousands of marks across hundreds of jurisdictions.

Partner Kate Bohmann, also ranked for Colorado in 2026, has litigated approximately 100 matters before the TTAB and federal courts and appears before the USPTO, the ITC, and WIPO. Together they give the Denver office a litigation-oriented trademark bench that also handles portfolio work. Because the Denver team came from an IP-only boutique, clients get a trademark group that has been focused on this work for decades, now backed by a national platform.

6. Brownstein Hyatt Farber Schreck

• Attorney/Key Figure: Airina Rodrigues, Partner, Intellectual Property Department
• Headquarters: 675 15th Street, Suite 2900, Denver, CO 80202
• Phone: (303) 223-1100
• Website: bhfs.com
• Practice Areas: Trademarks and trade dress, copyright, advertising, technology transactions, commercial contracts, and a wide range of business, real estate, and policy practices
• Firm Size: Large, with 12 offices and about 300 attorneys and policy professionals

About The Firm: Brownstein was born in Denver and runs a dedicated group for trademarks, copyrights, media, and brand protection within its Intellectual Property Department. Partner Airina Rodrigues focuses on trademarks and trade dress, including global trademark portfolio management, as well as advertising claims, technology transactions, and commercial contracts.

What distinguishes Brownstein is the breadth around the trademark work. A brand owner who also needs real estate, regulatory, or government affairs support can keep those matters under one roof, and the firm has described trademark clients across casino and gaming, cosmetics, food and beverage, and the pet industry. For a company that only needs a trademark specialist, that breadth is less relevant.

7. Polsinelli

• Attorney/Key Figure: John R. Posthumus
• Headquarters: 1401 Lawrence Street, Denver, CO 80202
• Website: polsinelli.com
• Practice Areas: Trademark, copyright and branding; intellectual property; health care; financial services; real estate; corporate; labor and employment
• Firm Size: Large, Am Law 100 firm with 900 attorneys in 21 offices

About The Firm: Polsinelli has operated in Denver since 1998, and its Trademark, Copyright & Branding group earned a national Tier 1 ranking for trademark law in the 2025 edition of Best Law Firms. John Posthumus was recognized in the World Trademark Review 1000 for Colorado in both the 2025 and 2026 editions.

The group’s services run from state and federal registration and worldwide portfolio management to TTAB oppositions and cancellations, clearance and risk analysis, copyright registration, and enforcement. It also advises on advertising, domain names, trade dress, and licensing or acquisition of IP assets. As a national firm with deep health care and financial services practices, it is a natural fit for regulated-industry brands.

8. Dorsey & Whitney

• Headquarters: 1400 Wewatta Street, Suite 400, Denver, CO 80202
• Phone: (303) 629-3400
• Website: dorsey.com
• Practice Areas: Trademark, copyright and advertising; patent; intellectual property litigation; corporate
• Firm Size: Large, international firm founded in 1912

About The Firm: Dorsey & Whitney runs a dedicated Trademark, Copyright + Advertising department with Denver among its core offices. The firm’s description of the work includes trademark strategy, clearance, prosecution and enforcement domestically and internationally, TTAB opposition and cancellation proceedings, domain name and UDRP matters, and intellectual property due diligence in transactions.

World Trademark Review recognized Dorsey’s trademark practice in Denver in its 2018 and 2019 editions, and the firm pairs trademark counsel with advertising, marketing, and unfair competition advice. That integration helps brands whose legal questions cross from registration into campaign review and licensing. As with other large firms on this list, the platform is built for brands with ongoing portfolio needs.

9. Sheridan Ross

• Headquarters: 1560 Broadway, Suite 1200, Denver, CO 80202
• Phone: (303) 863-9700
• Website: sheridanross.com
• Practice Areas: Trademark prosecution, TTAB proceedings, domain name disputes, copyright, patent prosecution, IP litigation, technology transactions and licensing
• Firm Size: IP boutique, 40+ attorneys, agents, and technical specialists

About The Firm: Sheridan Ross is exclusively devoted to intellectual property, serving in-house counsel at Fortune 500 companies, government agencies, start-ups, and individual inventors from its Denver office. Its trademark hiring describes a practice built around U.S. and foreign clearance, prosecution, licensing, due diligence, enforcement, TTAB practice, and domain name disputes.

Because the firm does only IP work, trademark clients get a team that is not splitting attention across unrelated practices, and the firm says this focus keeps costs efficient. The flip side is that it does not handle non-IP matters, so a brand owner who also needs general corporate or regulatory counsel will need separate representation for those issues.

10. Stemer Law

• Attorney/Key Figure: Sarah Stemer, Founder
• Headquarters: 2950 Brighton Boulevard, Suite 15, Denver, CO 80216
• Phone: (303) 928-1094
• Website: stemerlaw.com
• Practice Areas: Trademark applications and registrations, USPTO Office Action responses, international trademark strategy, IP litigation, copyright
• Firm Size: Boutique; woman-owned, established in 2019, serving clients nationwide

About The Firm: Sarah Stemer founded Stemer Law in 2019 as an intellectual property firm focused on trademarks, copyrights, and brand protection. She has more than 15 years of experience as a trademark attorney and has filed more than 1,000 trademark applications, and the firm points to real trademark trial experience alongside its filing work.

The firm’s distinguishing feature is its pricing: flat-fee trademark filings, with applications listed from $850, bulk discounts for larger portfolios, and contingency options for select copyright cases. Clients speak directly with a trademark attorney. As a boutique it has a smaller bench than the national firms on this list, which matters most for very large multi-country filing programs.

Common Questions About the Best Trademark Lawyers in Denver, CO

Do I need a federal trademark, or is registering my business name with Colorado enough?

They are different protections. Registering a company name with the Colorado Secretary of State identifies the entity and does not mean you own a trademark, and Colorado also runs a separate state trademark registration system. Federal registration through the USPTO covers your mark nationwide and is the route that trademark practices such as Four Reasons Legal’s prosecution and brand management group are built around. Many Denver businesses sell online or serve travelers, which can support federal filing even when operations are centered in one city.

How long does it take to get a trademark registered?

Timing depends on the USPTO and on whether it issues an Office Action. Stemer Law puts the average at about 12 months, longer if there is an Office Action or an opposition. Published USPTO data cited by Colorado firm Sequoia Legal, updated March 31, 2026, reported an average of 4.4 months to first action and 10 months from filing to registration or abandonment. Clearance searches before filing are meant to reduce the chance of delays.

Can I file before my Denver business launches?

Yes, in many cases. An intent-to-use application under Section 1(b) lets an applicant with a bona fide intent to use a mark begin the federal process before launch, though use requirements must still be met before registration issues. This is common for software, restaurant, and consumer product launches where signage, packaging, and domains are being paid for before the first sale.

What happens if the USPTO refuses my application?

A refusal is usually an Office Action, not the end of the application. Common grounds are likelihood of confusion with an existing mark and mere descriptiveness, along with specimen and identification problems. Firms like Faegre Drinker and Four Reasons Legal list Office Action responses and trademark disputes as part of their trademark work, and if someone else opposes your mark or seeks to cancel a registration, the dispute moves to the TTAB, where firms such as Four Reasons Legal, which lists opposition and cancellation work among its services, and Quarles & Brady, whose partners have litigated hundreds of TTAB and federal court matters, handle these disputes.

Do I need a Denver trademark attorney, or can I hire a firm anywhere?

Federal trademark filings and TTAB proceedings run through the USPTO, so the attorney does not have to be in Colorado. A Denver firm can still make sense for in-person strategy sessions, for brands in Colorado industries such as outdoor recreation, which is a stated focus at Faegre Drinker, and for infringement disputes that may end up in Colorado courts, where firms like Four Reasons Legal have local presence.

Should I choose a large firm or a boutique for trademark work?

It depends on the scope of your brand. A boutique like Stemer Law or Sheridan Ross can offer direct access to a trademark attorney and, in Stemer’s case, flat-fee pricing, which fits a first filing or a growing portfolio. A larger firm such as Kilpatrick Townsend or Holland & Hart brings more depth for multi-country programs, enforcement across marketplaces, and litigation, which matters when your brand is already being copied, or you are managing marks in many jurisdictions.
