Dorsey & Whitney LLP

A dynamic force across the United States for branding work, Dorsey & Whitney has a particularly prominent presence in Colorado. This “well-established team” possesses an unyielding commitment to client service: instead of just going through the motions, it takes extensive measures to ensure that the needs of brand owners are fully met. Over the last year, the discerning side has further expanded its already diverse capabilities with a growing focus on advertising and social media issues. The two star partners of the Denver contingent are Lisa Osman and Charlene Krogh. The “organised and very business-minded” Osman is “reliable and diligent”. “She is a big name here and simply brilliant – highly responsive, knowledgeable and easy to deal with.” Clients and fellow professionals also sing Krogh’s praises. “She possesses deep experience in all aspects of trademark practice, including selection, clearance, prosecution and enforcement, which includes Trademark Trial and Appeal Board (TTAB) and Uniform Domain Name Dispute Resolution Policy proceedings.” Krogh is “an extremely hardworking and conscientious lawyer”.

Holland & Hart LLP

“From a branding perspective, Holland & Hart is just fantastic and continues to impress. Its practitioners are extremely knowledgeable, responsive and professional”. “All the individuals there have strong profiles, speak regularly and represent some really high-profile clients.” As one happy customer enthuses: “They are unbelievably cost effective and feel like a seamless extension of our team. They consistently achieve outstanding results and have also successfully taken on a wide variety of projects that fall outside the classic trademark prosecution and dispute practice.” Squad captain Ester Martín Maillaro dispenses judicious advice to a slew of household names. “She is a tremendously experienced attorney and is phenomenal with regard to her day-to-day counselling.” With five of the world’s 100 most valuable brands under her care, Andrea Anderson serves as “the bedrock of the group”. Patrons are effusive in their praise for her: “An irreplaceable partner and an expert in her field, she is able to provide guidance on all risk-taking hypotheticals. Further, with her trustworthy business acumen, she is able to adapt and give the right support to different companies and in varying challenges across multiple jurisdictions.” Similarly, Larry Tronco is singled out for his “great customer service and legal capabilities. He is also incredibly responsive”. The “fantastic lawyer” is “personable and easy to deal with”. Scott Havlick is another “standout player at the firm”. As a founding partner of the Boulder office, “he has contributed to the success and longevity of the practice”. Havlick does a stellar job of overseeing trademark portfolios and is “really sharp and talented”. WTR 1000 debutante Tracy Gray is likewise a gifted IP portfolio manager. A key point of contact for an array of leading brands, “she is extremely professional and her expertise is exceptionally valuable”. For contentious concerns, Hope Hamilton, Donald Degnan and Timothy Getzoff are the first ports of call. “Hamilton is an excellent litigator who is able to provide amazing advice across a range of complex and difficult problems.” Degnan is another shrewd enforcer of rights. Feted for his nimble courtroom performances, he continually achieves practical results that maximise the value of clients’ intangible assets. Getzoff is a versatile and widely lauded trial attorney who has recorded countless victories in a myriad of trademark, copyright and patent cases; he leads the Holland & Hart IP litigation team with verve.

Lewis Roca Rothgerber Christie LLP

Formed following a merger in 2016, Lewis Roca Rothberger Christie has been firing on all cylinders over the past year, and the work has flowed in as both filings and TTAB proceedings continue to be in the ascendance. Its robust IP ensemble continues to expand its influence in both the trademark and patent realms as it tactically targets a number of key industries. Emily Bayton leads the efforts as the co-practice group head. She assists global clients with the building, maintenance and protection of their vital IP resources and is also au fait with the intricacies of trademark licensing.

Sheridan Ross

Sitting at the apex of the IP market in the Rocky Mountain region, due to both its heritage and size, Sheridan Ross’s name carries much prestige. As one peer extols: “I have had nothing but good experiences dealing with its lawyers and fully respect their consummate professionalism.” Proficient across the contentious/non-contentious divide, the firm exploits industry-specific knowledge across a variety of markets, which gives its branding insight a keen edge. At the start of 2017, Lewis Hansen took over the reins as the new practice group leader. He draws on almost 30 years of branding wisdom and excels at hammering out critical IP deals. Sabrina Stavish, who was recently elected to the firm’s executive committee, previously led the set. “A well-known, established portfolio manager”, she adopts a panoramic view of clients’ brands to ensure their positions on the market are unassailable. “Her advice is practical, transparent and based on a real understanding of business objectives. She acts as part of the team and overall decision-making process, not merely a legal technician.” Miriam Trudell offers invaluable support on the counselling front; she prosecutes, maintains and enforces trademark rights with zeal. When disputes arise, John Posthumus assuredly takes charge. “His strategic advice in trademark enforcement and litigation is second to none. He can handle complex and esoteric issues, and he always personally prioritises client service and works with you to provide alternative billing arrangements.”

Swanson & Bratschun LLC

“Swanson & Bratschun is an excellent option. Responsive and robust, it does well on a broad range of IP matters.” A vigorous patent department feeds into the respected trademark practice, which is “a strong choice for both prosecution and litigation”. The group takes pride in its ability to offer a 360-degree perspective on its clients’ IP portfolios, and founding partner Thomas Bratschun takes this principle to heart. “An easy-going and solid strategic adviser, he performs admirably in both trademark and patent issues.” “A fantastic lawyer”, Ian Saffer’s full-bodied practice is commended from all angles. The “savvy and knowledgeable practitioner” is a perceptive counsellor and rigorous enforcer.

Wilmer Cutler Pickering Hale and Dorr LLP

“WilmerHale is a heavy-hitting firm for IP litigation with a deep bench of skilled lawyers who can handle an assortment of matters.” A healthy clientele ranging from start-ups to Fortune 500s keeps the set busy, with consumer goods and telecommunications acting as two focal points. The majority of the firm’s accolades are a result of Natalie Hanlon Leh’s contribution; she is also “a leader of the local IP institute”. “An expert litigator and portfolio manager”, “she manages the Colorado office and has a strong reputation in the community. She is a go-to lawyer for both high-stakes trademark disputes and strategic advice”. “She is just a fabulous attorney and is superb at trade dress and design protection.”

Other recommended experts

A recent addition to Fox Rothschild, Christopher Beall has been a real boon for the firm’s IP practice. The accomplished trial attorney has a propensity for representing news and publishing clients in IP-related matters. “Knowledgeable, practical and strategic”, Jill Chalmers of Bryan Cave strikes a chord with patrons and peers alike. “Her expertise and good judgement is always appreciated; she can easily guide you through a multitude of issues to achieve maximum protection while keeping budgets in mind. She does a remarkable job.” Greenberg Traurig’s Gayle Strong has tackled a litany of IP cases and actions before the US Patent and Trademark Office. She also doubles as a percipient counsellor. Steve Zemanick runs his own shop Four Reasons Legal, from where he provides “superb clearance and registration work at a great price. Clear, pragmatic and responsive, he possesses a lot of experience and offers an amazing service”.
