Christina R. Walsh, Ph.D.
Professional Experience

Christina’s practice focuses on domestic and foreign patent preparation and prosecution, validity and infringement analysis, and claim chart preparation for licensing in the electrical and computer arts, with special emphasis on wireless communications and standards.

Client Work

Christina works with clients to obtain patent protection in the U.S. and around the world, and focuses on such technological areas as wireless communication standards including LTE, HSPA+, 802.11, and WiMax, electronics, computer architecture, processor design, computer software, internet applications, computer networks, antenna design, multimedia systems, video processing, digital television standards, and speech detection.

Christina has expertise in the latest wireless communications standards, which she uses to assist clients in producing licensable patents and leveraging their patent portfolios for licensing. For example, she worked closely with a large telecommunications client and served as a team coordinator within the firm to create a patent portfolio for LTE technology. As part of this effort, she examined the standards to develop the best possible claims, and has prepared and advised others on the preparation of claim mapping charts to the standards to facilitate licensing.

Christina aids clients in getting their valuable patents issued as quickly as possible, by successfully conducting accelerated prosecution in the U.S. by conducting on-site and over-the-phone examiner interviews, and enacting accelerated grant proceedings in various countries overseas.

Christina advises clients to help manage and grow their patent portfolio. For example, she performed validity and infringement analysis and advised a large investment capital client on potential patent acquisitions in the computer software and internet technologies area.

Christina also provides litigation support, including evaluating electrical and mechanical design features for infringement determination, and reviewing depositions.

Previous Work

Christina’s doctoral research investigated queuing, routing and scheduling in dynamic wireless sensor networks to optimize energy consumption, employing theory and simulations. Her research included characterizing the detection delay of a mobile intruder by a randomly deployed sensor network with unreliable connectivity, contributing new results to percolation theory.

Prior to joining the firm, Christina worked as a consultant performing prior art patent searches for cellular communication systems in connection with litigation matters. She also has industry experience as a network analyst in a large governmental organization and as a programmer in a software company.

Publications, Presentations and Recognition

Christina has published and presented work based on her research in wireless sensor networks at various high-profile international IEEE and Association for Computing Machinery (ACM) conferences.
