Ms. Riewerts is a partner and U.S. registered patent attorney in Oliver & Grimsley’s intellectual property group. Her practice focuses on assisting clients in securing, maintaining, protecting, and commercializing intellectual property in the U.S. and abroad, and regularly counsels individuals and businesses, including start-up ventures and established entities.  She also has significant experience in patent, trademark, copyright and related litigation and joined Oliver & Grimsley after handling multifaceted intellectual property and corporate litigation matters for large New York City and Washington, D.C. firms.

Ms. Riewerts’ patent prosecution and litigation practice includes counseling and advising clients regarding a variety of technologies, including agricultural and biological systems and engineering processes, environmental devices, mechanical and medical devices, pharmaceuticals, electronic methods and devices, computer hardware and software, business methods, clothing accessories, alcohol breweries and distilleries, culinary instruments, consumer products, and other technologies.  Ms. Riewerts’ sophisticated patent litigation experience greatly enhances her ability to counsel clients engaged in the patent process.  She also uses her engineering degree and background to work closely with inventors and technical experts to prepare reports, conduct intellectual property due diligence investigations, and provide intellectual property analyses and evaluations.

Ms. Riewerts’ services include:

•  Patent Novelty Search. Ms. Riewerts searches for preexisting patents (“prior art”) before drafting an application to assist businesses or inventors considering whether to begin the patent process.  Knowing what prior art exists before drafting a patent application is beneficial to the client.  Sometimes, Ms. Riewerts’ search results reveal very little prior art close to clients’ idea and she can write a broader application on the clients’ behalf.  In other instances, Ms. Riewerts may find that the invention already exists or that there are similar inventions in the art.  In these cases, it is cost effective for the client to be aware of existing prior art up front.  The right answer may be not to file an application or to design around similar features.

•  Patent Drafting and Prosecution.  Ms. Riewerts drafts patent applications to protect clients’ interests, and works to efficiently advance applications through the patent examination process in U.S. Patent and Trademark Office and foreign patent offices.

•  State-of-the-Art Search.  Ms. Riewerts evaluates and analyzes patents and other literature to identify industry trends, competitive advantages, and competitor disclosures. Businesses rely on Ms. Riewerts for this kind of research and analysis for numerous reasons, including evaluating a market to decide whether to enter it, identifying potential competition and reviewing a technology looking for entry points.

•  Patent Clearance or “Freedom to Operate” Search.  Ms. Riewerts evaluates clients’ inventions against issued patents in order to evaluate and reduce risks for litigation that may ensue.

•  Intellectual Property Portfolio Analysis.  Businesses may create a collection of intellectual property assets. Over time, it can be difficult to identify the strength and value associated with these assets.  Ms. Riewerts works with accountants, experts and inventors to evaluate intellectual property assets, identify opportunities and risk factors, and develop a management strategy for the future.

•  Licensing.  Ms. Riewerts negotiates and structures lucrative licensing agreements between patent owners and those pursuing use of the patented technology.

•  Litigation.  Ms. Riewerts evaluates the merits of letters alleging infringement, and negotiates resolutions to emerging disputes. In addition, she also plays the opposite role in rendering an opinion that a competitor is unfairly asserting rights against clients. Litigation is essentially a competitive tool that may ultimately ensue.  Therefore, Ms. Riewerts is well prepared to represent each client’s best interest in disputes over patent rights while keeping in line with business objectives.

Ms. Riewerts’ work experience also includes conducting trademark branding practices, intellectual property reviews and maintenance, clearance and infringement investigations, reviewing marketing materials and editorial publications for trademark compliance, coordinating enforcement efforts on behalf of clients, and drafting non-disclosure and non-compete agreements designed to protect a client’s intellectual property.

Ms. Riewerts also has experience prosecuting trademarks and copyrights and representing clients in contested proceedings before of the United States Patent and Trademark Office and with domain name resolution under the Uniform Dispute Resolution Policy.  Ms. Riewerts is a business counselor and litigator who focuses on client service, understands the significance of identifying a client’s business goals and objectives, and creates a strategy designed to cost effectively achieve those objectives. In addition, Ms. Riewerts has resolved numerous intellectual property disputes outside of court in order to facilitate and further the best interests of her clients.

Prior to her tenure at Oliver & Grimsley, LLC, Ms. Riewerts practiced law as an intellectual property litigation and patent prosecution attorney with Bowie & Jensen, LLC, a Baltimore business law firm.  She also practiced as a patent litigation attorney with Morgan & Finnegan, L.L.P., a New York City law firm specializing in intellectual property and with McDermott Will & Emery, a Washington, D.C law firm.

Ms. Riewerts is a graduate of the Pennsylvania State University Dickinson School of Law.

Ms. Riewerts also holds her Fundamentals of Engineering/Engineer in Training Accreditation (FE/EIT) from the National Council of Examiners for Engineering and Surveying (NCEES).
