Joe assists clients in achieving their business goals through creative intellectual property solutions. In his prosecution practice, he assists clients in obtaining, maintaining and registering patents, trademarks and copyrights. Joe has assisted numerous Fortune 100 companies in developing and augmenting their patent programs through the successful use of incentive programs and invention harvesting sessions. Joe often utilizes creative prosecution strategies for achieving clients’ business goals. These strategies include the use of early pre-grant publication procedures to obtain patent rights within as little as thirty days, maintaining continuing prosecution for important inventions, and devising strategies to limit clients' costs in creating and managing their patent and trademark portfolios. Joe has extensive experience in the chemical, mechanical, electrical, and business method arts.

In his counseling practice, Joe assists clients in the successful launch of new products, the analysis and navigation of competitive intellectual property threats and the development of strong intellectual property programs. Joe also assists clients in the assessment and acquisition of intellectual property (including the due diligence related thereto) and in the valuation of internal and external intellectual property.

In his litigation practice, Joe has been successful before juries and Judges. He has seized the goods of infringers, obtained preliminary injunctions and succeeded in full trial of damages and permanent injunction. Joe also is adept at utilizing litigation to achieve clients’ business goals prior to the incursion of costs associated with full litigation. Joe believes in strong and simple presentations of facts and law and the utilization of technology to simplify issues. He also assists clients in “right-sizing” their litigation to achieve their business goals.
