Andrus provides a tailored service at an affordable rate, which scores it high marks from clients. One comments: “During my time in the IP business, I have not come across any US law firm that can compete with the quality and value that Andrus supplies.” Zooming in on prosecution, the team maintains 4,000 US issued patents and is currently responsible for over 1,000 further pending US applications. Integral to the smooth running of the non-contentious practice, Peter Holsen comes in for effusive praise: “Peter always impresses with his technical understanding and complete command of US patent law. He is also extremely service-minded, very responsive and always kind and polite in correspondence. He’s the number one choice.” He plays a key role representing Brunswick Corporation, which has instructed the outfit since the 1930s, as does Ryann Beck, who makes her debut in the IAM Patent 1000 this year. “Ryann is incredibly smart and highly adept at working with inventors. She gives honest assessments and detailed, accurate advice.” Her other patrons include GE Healthcare, which she supports on biomedical technology matters working alongside Joseph Kuborn and Benjamin Imhoff. Kuborn provides outstanding leadership to the practice and is elevated in his strategic thinking, thanks to his exposure to high-level patent procurement, conflict resolution and transactional work. Imhoff is “extremely knowledgeable and proficient at handling the most difficult cases – he doesn’t give up until he has found a good solution”. The ensemble’s litigators never let the side down either, but drive satisfying results by deploying both technical expertise and advocacy skill. The top litigators on deck are Aaron Olejniczak and Christopher Liro, who make an excellent team. Of the former, one source comments: “I recommend and refer to Aaron without qualification. His level of expertise, promptness and ability to effectively communicate is outstanding. He is a really business-focused litigator.” Liro is nimble in his ability to quickly adapt to cases involving diverse technologies; he knows how to develop strong litigation themes and strategies, which serves him well in court and in negotiations.

Firm Profile

Andrus Intellectual Property Law LLP has a distinguished history of providing world-class legal services exclusively in the area of IP law. We assist our clients in all phases of IP acquisition, management and enforcement.

Our firm was founded in 1939 as a solo law practice operated by Elwin A Andrus. Over the years the firm has grown significantly and has operated under several different names, including, for an extended period of time, as Andrus, Sceales, Starke & Sawall LLP. The firm has always maintained a home office in Milwaukee, Wisconsin, but has operated satellite offices in Madison, Wisconsin and Newburyport, Massachusetts, among other locations. In 2020, we moved to our current home office in the newly constructed BMO Tower in the heart of downtown Milwaukee.

Andrus represents a diverse clientele including small and large US companies, international corporations from North America, Europe, Asia and Australia, universities, and startups. Our attorneys and patent professionals collectively have a wide range of technical expertise, including in the fields of biology, biomedical engineering, biotechnology, chemistry, civil engineering, computer software and hardware, electrical engineering, electronics, fluid dynamics, mechanical engineering, medical technologies, metallurgical engineering, and physics.

Andrus has a proven track record of obtaining and managing thousands of patents, trademarks and copyright for our clients. We help clients recognise protectable rights, develop filing strategies, and draft and prosecute applications. We have extensive experience handling international prosecution and portfolio management, particularly via the Patent Cooperation Treaty, the European Patent Office and the national patent and trademark offices of countries around the world. Also, we serve as an excellent partner to many non-US law firms in need of US counsel for their clients. The boutique size of our firm combined with our extensive legal and technical expertise allows us to efficiently and effectively handle all of the above-described matters for our clients at very reasonable cost.

Members of our firm’s IP litigation group routinely handle matters in state and federal courts across the United States, including pursuing and defending claims of patent infringement, trademark infringement, copyright infringement, unfair competition, trade secret violations, licensing disputes and related IP contract disputes. A core competency of our litigation team is trying complex cases before judges and juries. Members of the firm’s IP litigation group use their experience to comprehensively address all phases of litigation, including counselling, trial, discovery, Markman hearings, pretrial proceedings, mediation and appeals. Like our prosecution attorneys, all of our litigation attorneys have had technical training and are registered US patent attorneys with experience handling prosecution matters at the US Patent and Trademark Office. More importantly, our litigation attorneys have considerable hands-on courtroom experience, including significant jury trial experience. This unique blend of technical skill and courtroom experience yields proven, cost-effective results.

Members of our firm’s IP litigation group also have extensive experience handling administrative patent and trademark appeals, interferences, derivation proceedings, petitions, protests, reissues, re-examinations, post-grant reviews (post-grant reviews and inter partes reviews), opposition proceedings, and cancellation proceedings at the US Patent Office and Trademark Office. Our attorneys also counsel clients on protecting proprietary information as trade secrets and through non-disclosure agreements.

Many of our attorneys are active members of US and international IP societies, including the International Association for the Protection of Intellectual Property (AIPPI) and the International Trademark Association (INTA). Our active participation in these organisations expands and cultivates close working relationships with a wide network of IP professionals around the world. This network ensures that our domestic and international clients enjoy the highest quality service at a great value.
