Thought Leadership


Eric Gill is an associate in the Intellectual Property (IP) Practice Group in the firm’s San Diego (Del Mar) office.

Areas of Practice

Mr. Gill enjoys a dynamic IP practice that draws heavily on his industry experience and education in electrical engineering, and emphasizes patent litigation and post-grant proceedings, as well as strategic IP portfolio development and counseling (including patent drafting and prosecution). His practice further encompasses handling and litigating trademark, trade secret, copyright, unfair competition, tortious interference, and contract disputes, as well as providing counsel, due diligence, and analysis in connection with transactional matters, technology licensing, patentability, freedom-to-operate, and patent portfolio landscaping.

Mr. Gill’s patent litigation practice has recently focused extensively on standard-essential patents and related FRAND issues in the wireless and cellular technology spaces. For example, he has litigated numerous patents across a broad spectrum of technologies in the 2G (GSM/GPRS/EDGE), 3G (UMTS/WCDMA/HSPA), and 4G (LTE/LTE-A) cellular standards, including speech coding, adaptive modulation, random access, ACK/NACK, HARQ, MIMO, carrier aggregation, multimedia broadcast multicast service, FDD, TDD, CDMA, and OFDM. Additionally, he has litigated patents directed to such technologies as GPS and location services, control programs for wireless devices, power management and power control circuitry, image sensors and graphics processors, audio/video codecs, receiver architecture and circuitry, spinal surgery tools, and online mortgage exchanges.

Mr. Gill is also a registered patent attorney and represents clients before the US Patent Office, including in PTAB proceedings (e.g., Inter Partes Reviews) and in drafting and prosecuting patent applications. In this regard, he deals in such technologies as telecommunications and wireless, analog and RF circuits and systems, Bluetooth, semiconductors, MEMS, augmented and virtual reality, big data/analytics, data security/encryption, social media, software/firmware, and mechanical and medical devices.

Before joining the firm, Mr. Gill landscaped patent portfolios in the telecom RF/analog space when he worked in the IP strategy group of one of the world’s leading semiconductor and wireless-technology companies.

Before becoming a lawyer, Mr. Gill worked in industry as a microwave and RF design engineer at Northrop Grumman, where he designed microwave integrated circuits and RF systems for aircraft and satellite communications and for counter-improvised-explosive-device-warfare technologies. He also worked as an RFIC designer at NextWave Wireless, a San Diego semiconductor company that developed chip-sets and wireless technology for WiMAX and 4G LTE.
