Robert M. Siminski ( Bob )

Principal / Detroit Metro Office

Bob drafts, prosecutes, enforces, and licenses patents primarily in the chemical and mechanical arts. Bob also focuses on intellectual property related due diligence, portfolio management and analyses, strategic counseling, valuations, opinions, and litigation management.

A significant portion of Bob’s practice involves counseling clients on patent strategies in Asian jurisdictions. As a longstanding Vice Chair of the Intellectual Property Owners Association (IPO) Asian Practice Committee (APC), Bob meets with business leaders and patent office directors from China, India, Japan, Korea, and Taiwan, among other countries, on a regular basis. He also travels to Asia frequently and meets face to face with clients and law firm partners. As a result, Bob has a deep understanding of the ever-changing IP landscape and business trends that affect innovative companies in Asia as well as U.S. companies doing business in Asia.

Bob’s clients appreciate that he gets to the point. He is concise, direct, and does not waste their time. They also value his dedication not only to providing outstanding legal counsel, but also for respecting their budgets. Whenever possible, Bob’s objective is to help his clients avoid disputes by identifying and resolving problems and obstacles early on. However, when disputes do arise, he has also been able to build bridges to settlement, on multiple occasions, in scenarios where the conflict was so acrimonious that even his client believed intense litigation was the only recourse. As a result of Bob’s innately creative problem-solving skills, he has taken seemingly impossible situations and helped make resolution possible.

Prior to practicing law, Bob served as an analytical chemist in the oil and natural gas industry, where he conducted analysis on soil and water for environmental contamination, directed tests on fuel recovery, and designed a fuel recovery system.

When he is not in the office, Bob is likely pursuing his second career as an “International Golf Ambassador,” a title given to him by friends and colleagues around the globe.
