Andrus Intellectual Property Law, LLP

Milwaukee roots and an IP focus

The legal name is Andrus Intellectual Property Law, LLP, while the website uses Andrus Law as its shorter public name. The firm is based in Milwaukee, Wisconsin, and traces its history to 1939. Its work centers on intellectual property acquisition, management, enforcement and transactions.

The listed services cover patents, trademarks, copyright, IP litigation and related agreements. The firm also counsels clients on IP strategy. In my opinion, this clear focus helps prospective clients understand the type of legal work the attorneys handle.

Domestic and international matters both appear throughout the attorney profiles. The firm manages the prosecution and maintenance of global IP portfolios and handles U.S. filings that claim priority from foreign applications. Its patent work also includes national stage applications under the Patent Cooperation Treaty.

How intellectual property work develops

IP matters often begin with an assessment of the asset and the client's business plans. For patents, that may involve studying an invention, searching relevant technology and deciding which features belong in the claims. Trademark work calls for attention to the proposed mark, the goods or services connected to it and earlier marks that may affect registration.

Copyright follows a different path because it protects original expression rather than inventions or brand identifiers. Registration, ownership, licensing and enforcement may each require separate analysis. The firm's inclusion of all three areas gives clients access to counsel across several forms of intellectual property.

Patent prosecution across varied technologies

The attorney profiles identify work involving mechanical, electrical, software and medical technologies. That range matters because patent applications must explain technical subject matter in precise language. Claims also need careful drafting because their wording defines the legal boundaries of the requested protection.

Ryann H. Beck handles domestic and international patent and trademark prosecution and enforcement. Her listed technical areas include medical devices, patient monitoring and treatment devices, computer software, electronic circuits and mechanical devices. Benjamin R. Imhoff also works with medical technology, including mechanical therapy devices, electrical patient monitoring systems and software-based imaging.

Dillon E. Durnford focuses on domestic and international patent prosecution for complex technologies. His experience covers electrical systems, software and automation. Donald J. O'Brien handles patent prosecution for computer technologies and is a registered patent attorney. His earlier work as a professional software engineer included software, hardware, network implementation and project management.

Mechanical systems and product development

Emily M. Chilson handles domestic and international patent and trademark prosecution and enforcement. Her technical work includes wearable apparel, consumer packaged goods, engines and control systems, transportation equipment, paper industry machinery, pumps and mechanical devices. This subject mix reaches consumer products as well as industrial equipment.

Peter T. Holsen works on patent and trademark prosecution and enforcement in the United States and abroad. He also develops global IP strategies. His technical areas include mechanical and electromechanical technologies, engines and control systems, oil and gas technologies and food processing.

Joseph D. Kuborn handles patent and trademark prosecution in domestic and international settings. He also provides analysis related to product development. His listed experience includes medical devices, RF technology, wireless devices, computer software and hardware, car wash controls and furniture designs.

Patent advice and application work

John P. Dyro advises on patentability and infringement. He also assists with patent and trademark applications before the United States Patent and Trademark Office. Melissa L. Kleine addresses patentability and infringement questions involving mechanical and electromechanical technologies, alongside her prosecution and enforcement work.

Patentability analysis generally asks whether an invention meets the legal standards for protection in light of earlier publications and products. Infringement analysis compares patent claims with an accused product or process. Those inquiries involve different questions, even when they concern the same technology.

After an applicant files a patent application, a USPTO examiner may issue an office action about the claims or supporting disclosure. The response may present legal arguments, amend claims or clarify technical points. International filing plans add deadlines and jurisdiction-specific requirements, so the stated work with foreign priority and PCT national stage filings is relevant to companies seeking protection in several countries.

Trademark, copyright and portfolio management

The firm's trademark work includes prosecution, enforcement and administrative disputes. Trademark prosecution commonly involves clearance, an application, examination and responses to issues raised by the USPTO. Continued protection also calls for timely maintenance filings and attention to marketplace use.

Several attorneys combine patent and trademark work in their practices. Beck, Chilson, Dyro, Holsen, Imhoff, Kleine, Knight and Kuborn each list domestic and international prosecution and enforcement across both fields. Their profiles connect brand work with technical and product-related counseling.

Thomas R. Knight brings legal, business and technical training to IP counseling. He has a master's degree in business administration and a bachelor's degree in biomedical engineering. His practice includes domestic and international patent and trademark prosecution and enforcement.

Copyright and ownership questions

The practice pages include copyright among the firm's services. Copyright matters can concern authorship, ownership, registration, permissions and alleged unauthorized use. Contracts may also determine who owns material created by employees, contractors or commercial partners.

Portfolio management extends beyond obtaining registrations. Owners must track deadlines, record changes in ownership and decide which rights still support current products or brands. The firm states that it handles prosecution and maintenance for global IP portfolios, which places ongoing administration within its stated scope.

Disputes in courts and administrative forums

The firm's disputes work reaches federal courts and several intellectual property tribunals. Christopher R. Liro handles IP litigation in federal district and appellate courts. He also works on proceedings before the Patent Trial and Appeal Board and the International Trade Commission.

Aaron T. Olejniczak handles patent and trademark disputes in district and appellate courts. His work includes inter partes review before the PTAB. He also handles trademark opposition and cancellation proceedings before the Trademark Trial and Appeal Board.

Each forum has its own purpose and procedure. District court litigation may address infringement, validity and remedies, while an appeal asks a higher court to review legal or procedural rulings. An inter partes review gives a petitioner a route to challenge certain patent claims before the PTAB.

Trademark proceedings and dispute planning

TTAB opposition proceedings address whether the USPTO should register a pending trademark. Cancellation proceedings challenge a registration that has already issued. These administrative cases focus on registration rights, while marketplace disputes may raise separate questions for a court.

Enforcement work can start with investigation, claim analysis and communication between the parties. Some matters proceed to a negotiated resolution, while others require formal filings. The firm's stated experience covers enforcement actions, litigation and administrative proceedings.

Transactions and the structure of the team

Intellectual property rights often appear in business agreements as well as contested matters. The firm assists with licensing, development agreements and other IP transactions. Liro's profile specifically identifies licenses, joint development agreements and dispute resolution.

A license sets the scope of permitted use and may address territory, duration, payment terms and quality control. A joint development agreement can assign responsibility for existing rights, new inventions and confidential information. Clear ownership terms can shape what each party may use after the project ends.

The attorney roster names 12 lawyers and gives individual practice descriptions. The listed technical backgrounds across the team include biology, biochemistry, biotechnology, chemistry, computer software and hardware, electrical engineering, mechanical engineering, medical devices, pharmaceuticals and physics. That information lets a prospective client compare the subject matter of a legal issue with the experience described for each attorney.
