James R. Carpenter

Senior Attorney


James R. Carpenter has over 10 years of patent experience and his practice focuses on all aspects of patent counseling and patent prosecution in relation to a wide variety of computer, electrical and internet-related technologies. He drafts and prosecutes patent applications and counsels clients on patent portfolio strategies, patent infringement, validity and clearance. In addition to securing patents, he has litigated contentious matters before several U.S. district courts and the U.S. International Trade Commission, which equips him with significant insight into developing and defending patent portfolios and evaluating third-party patents.

James handles the prosecution of numerous patent portfolios, including those of start-ups, growing industrial companies and publicly traded consumer companies. James is particularly experienced with inventions relating to display and semiconductor production including circuitry design and layout, lithography, processor and memory optimization, and back-end packaging. Additionally, James has extensive software experience with inventions relating to operating systems, cloud computing, big data, data mining, internet security/authentication, e-commerce, user interfaces, and nanotechnology. He can also program in assembly, C, C++, Perl and Java, along with many variants of other programming languages.

Prior to joining Drinker Biddle, James gained in-house, EPO and German patent experience while working in Munich, Germany. There, James evaluated invention disclosures to determine the value of obtaining a patent, drafted and enforced patent licensing agreements to protect his company’s market share and to defend against patent infringement lawsuits, conducted opposition proceedings in the EPO to validate and invalidate allowed patent applications, and drafted and responded to infringement and invalidity contentions to determine the likelihood of infringement and the value of a portfolio.

While in law school, James was a member of the Glushko-Samuelson Intellectual Property Law Clinic.
