Before practicing law, I worked in the research and development department of a healthcare data analytics company. In this role, I saw firsthand how innovation can drive a company’s success. During law school, I interned with the Office of General Counsel at the American Medical Association, where I came to recognize the unique role of in-house counsel in protecting the interests of a business. In my patent prosecution practice, I draw upon these experiences to work with our clients in obtaining intellectual property protection that advances their business goals.

At HFZ, I prepare and prosecute U.S. and foreign patent applications in the mechanical and electro-mechanical arts. I have experience pursuing our clients’ patent rights in a variety of technologies, including medical devices, neuromarketing tools, child care products, information systems, and process control devices. I also assist in counseling our clients with regards to patentability, validity, and infringement matters. Additionally, I help clients obtain trademark protection and manage their trademark portfolios.

I work with various large and small corporate clients in a diverse range of technology areas including software, electrical, and mechanical technologies. I believe there is no single, rigid approach to serving all clients, neither from a technical standpoint nor from a business perspective. The best IP legal services are customized to meet the needs of each client.

I spent several years as an electrical engineer before joining Hanley, Flight & Zimmerman in 2003. I developed electrical hardware architectures for multimedia platforms of next-generation mobile phones at Motorola, Inc. In that capacity, I worked with several different microprocessor families, digital multimedia codecs, LCD controllers, compression algorithms, and communication protocols. At Palm, Inc. I developed electrical hardware architectures for Palm’s line of premium handheld PDA devices, and I wrote firmware and software for mobile computing.

My current practice involves preparing and prosecuting domestic, international, and foreign patent applications. I also counsel clients on non-infringement and invalidity positions as well as other patent related matters.

We strive to know each client’s business. Leveraging that knowledge, we facilitate clients’ ability to use their intellectual property to expand operations with confidence. With a focus on the medical, electrical and mechanical arts, my practice provides non-infringement and invalidity opinions to clear products or assure clients freedom to operate.

Working with engineers and in-house counsel, I help our clients generate patent portfolios and expand their businesses by developing and executing prosecution strategies including post-grant proceedings. I also coordinate with overseas counsel in opposition proceedings, procure federal trademark registrations, and manage global trademark portfolios, which includes managing and litigating trademark opposition and cancellation proceedings. Additionally, I draft and negotiate licensing agreements, provide counseling related to copyright issues and procure federal copyright registrations.

Christopher N. George, JD, MSECE, BSCompE

I believe our clients are best served by offering a comprehensive, strategic solution to their intellectual property and business needs. At HFZ, we’ve built a team to provide our clients a wide variety of non-litigation, intellectual property services, which they can leverage to develop and grow their businesses.

I have extensive experience in a wide range of legal arenas including patent drafting and prosecution, patent portfolio development and management, brainstorming and IP capture, patent landscaping, patent reexamination, litigation, licensing, and due diligence and opinion analysis. I also serve as seconded in-house counsel for a Fortune 5 client to advise them on patent strategy matters.

My experience in technology spans a wide variety of consumer products and manufacturing systems as well as imaging systems, image processing, analog and digital audio, casino gaming systems, telecommunications and data networks, distributed computer systems, electronic storage devices, financial trading systems, anti-virus and security software, and signal processing applications.

My focus is on our client’s business objectives. Our ultimate goal is to provide counsel and patent prosecution strategies that advance our client’s agenda. This is best achieved in a long-term relationship that fosters an in-depth understanding of our client’s business and the competitive landscape in which they operate. On the prosecution side, this level of commitment ensures we do not just secure patent claims; we issue claims that are tailored for ready enforcement when the need arises.

I’m actively involved in defensive and offensive patent issues including ex parte and inter partes reexaminations, reissues, Public Use proceedings, European opposition proceedings, and due diligence investigations in support of product releases, enforcement actions and/or company acquisitions. I have represented clients in litigation and licensing involving patent infringement, trade secret misappropriation, trade dress infringement, and contract disputes. Leveraging my deep experience in such a wide range of issues and technologies, I’m able to help my clients build and manage valuable patent portfolios and avoid the pitfalls of competitive holdings.
