Adsero IP

Adsero IP has significantly expanded and become a more well-rounded IP boutique in the process; remaining unshakeably strong on the patent side, it now also runs an excellent trademark practice and makes its first appearance in the WTR 1000 this year. Especially noteworthy is the ensemble’s Asia practice, which is run by Amy Hsiao, a fluent Mandarin speaker who knows the lay of the land in Greater China and excels at guiding US companies with IP issues there. Locally, Adsero IP is the go-to for some of the largest Rocky Mountain-based telecommunications companies as well as leaders in the ski and tourism industry; the timely, cost-conscious service and strategic creativity of managing partner Ian Saffer draws in the crowds. A versatile counsellor and litigator, he takes the time to think commercially about his clients’ brands and IP rights, while his extensive trial experience, instils confidence in his ability to provide protection come what may.

Bryan Cave Leighton Paisner LLP

Bryan Cave Leighton Paisner has the resources to handle any trademark matter and, as an integrated global firm, is in pole position to guide companies on brand launch and development in the United States and internationally. Putting it on the map in Colorado is portfolio manager and enforcer Jill Chalmers, who undertakes an incredible volume of trademark work without dropping the ball on a single file. Chalmers is down to earth and easy to connect with; she listens to her clients, understands their business needs and then delivers.

Dorsey & Whitney LLP

A hotbed of entrepreneurialism, Denver is dynamically evolving as a business, legal and IP community and right at the heart of things is Dorsey & Whitney, long an engine of local trademark practice. The firm is also considered a national powerhouse when it comes to brands thanks to its deep specialisation not only in trademarks but also in associated areas such as internet law, social media and advertising. A former chair of Dorsey’s trademark practice, Lisa Osman remains influential as a leader in the group, particularly when it comes to the deployment of technology for efficiency enhancement. Vastly experienced as a counsellor on domestic and international matters, Osman is a wise strategist respected for her problem-solving proficiency. Charlene Krogh is another repository of trust for vibrant brands across many sectors. As an astute IP asset manager, monetiser and enforcer, and an expert in marketing and advertising, Krogh can think 360-degrees around any issue and come up with a smart, sensible and practical approach. She co-manages TheTMCA.com blog and is as up to date on trademark developments as they come.

Faegre Baker Daniels LLP

As it has in other parts of the country, Faegre Baker Daniels has been making moves in Colorado – in May 2019 it unveiled Emily Bayton as its new local signing – and this year debuts in the WTR 1000 rankings for the state. The firm looks to have made an inspired choice in Bayton; “Emily is a seasoned trademark practitioner who provides extremely well-thought out advice alongside an unparalleled client service. It is always plainly evident that she cares – it’s something that distinguishes her from her peers in the field.” With her broad and international IP protection and management expertise and litigation know-how, she fits in well in an integrated cross-office group that covers all the bases for brand owners.

Holland & Hart LLP

With a “strong and cohesive trademark group full of great attorneys” doing “interesting and relevant things for a fantastic set of clients”, Holland & Hart leads the IP field in Colorado. Alongside delivering quality work on technically sophisticated briefs, the group is at the forefront of legal technology development in trademarks and has created a suite of innovative AI tools and other solutions to automate and streamline the more administrative aspects of the practice. This process saves clients money and frees up lawyers to focus on advising long-range commercial brands. The scope of the ensemble’s diversity initiatives also pays testament to the forward-thinking nature of the team. Great leadership is provided by international portfolio manager and strategist Ester Martín, an experienced and committed lawyer who invests in her team and gives her all for clients. A former in-house counsel, she has no problem getting in sync with companies on a commercial level – and she fully appreciates their need for an efficient service. Andrea Anderson and Larry Tronco are also inspiring senior members of the team who get a great write up for their work safeguarding household-name companies: “Andrea is just a genius – she gives pragmatic advice but infuses it with fantastically creative and unique ideas regarding brand creation and protection.” “Larry is someone you can trust unconditionally – he’s incredibly practical and a top counsellor.” Both garner plenty of positive feedback from foreign associates, which attests to their excellent international reputations. Firm life without Scott Havlick would be far less rich; he has practised here for over three decades and become an engine of its innovation effort. A vital resource for patrons, too, Havlick has cracked the code of IP valuation and maintains a fully-specced non-contentious and contentious practice. For a specialist in enforcement, look to Hope Hamilton, whose knack for facilitating quick wins to disputes has caught the eye of companies accustomed to instructing more expensive coastal players. “Hope is really reasonable. She has an impressive breadth of experience and does a great job for those she represents.” If litigating in court is inevitable – or desirable – the firm can bring the heat by fielding Hamilton and/or veteran trial lawyer Timothy Getzoff. With Tracy Gray on deck, the Holland & Hart team can lay claim to a well-rounded brand offering; Gray’s expertise in advertising, privacy and consumer protection is vital to those operating in highly competitive and dynamic markets. Joining them in the guide for the first time this year is Andrew Roppel, a former USPTO examiner and guru in search, clearance and prosecution.

Perkins Coie LLP

A quick glance at the ever-increasing number of filings and disputes under the care of Perkins Coie reveals a trademark practice in fine fettle. The firm has capitalised on in-house counsels’ desire to increase the work volume for a consolidated number of outside providers and to take advantage of discounts; with its deep bench of trademark specialists and well-integrated supporting groups (in areas such as regulatory law), it is the ideal choice. The Denver office is buzzing right now and growing fast; credit for this must go to Alexander Garcia, a popular partner for emerging innovators as well as established industry leaders. “Alex is fantastic – one of the best trademark attorneys you can find. He is proactive, thoughtful and a zealous advocate for his clients’ interests and highly effective at executing worldwide trademark strategies cost effectively to budget.” Assisting Rent the Runway with global IP procurement, management and enforcement is one of the exciting projects he has been getting stuck into recently.

Sheridan Ross

Sheridan Ross adapts well to different clients and offers a neatly tailored and personal service that emphasises the achievement of commercial objectives. The close-knit, consistent and stable group has over 110 years of experience collectively and can confidently handle any US or international brand management or enforcement matter. Sabrina Stavish, Miriam Trudell and Sarah Schneider, for example, work together to service the full global trademark needs of a top 10 Fortune 500 company. Stavish has seen so much in the practice that she knows what play to call in any situation; she is also an excellent coach and mentor. Co-managing partner Trudell, who leads the trademark practice, is another prosecution and portfolio mastermind; she also has abundant TTAB experience. Schneider navigates unerringly through difficult online brand management and enforcement issues; she takes the practice personally and always goes the extra mile to make her clients’ desired outcomes a reality. Lewis Hansen and Pamela Hirschman have joined forces to advise a multi-billion dollar brewery – and 30-plus year patron – on global strategy and prosecution. Brand development and commercialisation is the metier of veteran Hansen. Former USPTO examiner Hirschman has been busy in the cannabis space of late, showing a deft touch on novel issues in this fast-evolving area.
