    As one of the founding partners of HFZ, I have over 20 years experience in patent litigation, patent prosecution and patent counseling. My experience representing clients includes a diverse range of technologies, including software, telecommunications (PSTN, AIN, Cellular and VoIP technologies), analog and digital circuitry, microprocessor architecture, virtual private networking, internet technologies, audience measurement technologies, cloud computing, virtualization, data warehousing, network security, memory architectures, green technologies, safety products, window coverings, dock safety equipment, surgical equipment, firearms, and child care products.

    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.

    On the Martindale-Hubbell site, a peer reviewed rating, I recently received a Preeminent status AV (4.8 out of 5). Read more.

In addition to my education, I spent several summers at Gentex, an automotive component supplier, where I contributed to process improvement efforts in a highly automated, industrial setting. I worked with multiple technologies including vision systems, glass processing, and microelectronics. I enjoy working with innovators and am excited to work with them to secure protection for their ideas.

    At HFZ, I am honored to protect the innovation and technologies of our clients. Prior to joining HFZ, I was a mathematics teacher at Noble Street College Prep, where I taught trigonometry. At Law Bulletin, I programmed automated test software for new developing applications. At Continental Automotive Group I ran a series of EMC tests and programed transmission control units for 4×4 SUVs.

    HFZ allows me to use my diverse background and skill set to problem solve during the preparation and prosecution of patent applications.
