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 also encompasses IP litigation, technology licensing, and transactional matters.

Mr. Gill’s IP litigation practice focuses on patent infringement and FRAND/standard-essential-patent litigation. His experience includes pre-filing investigation, motion practice and fact/expert discovery, infringement/invalidity contentions, claim construction, trial, post-trial motions, and settlement negotiation. He has litigated patents involving such technologies as the 2G (GSM/GPRS/EDGE), 3G (WCDMA), and 4G (LTE) wireless standards; CDMA; speech coding; TDD; multimedia broadcast multicast service; adaptive modulation; MIMO; random access; receiver architecture and circuitry; GPS and location services; control programs for wireless devices; power management and power control circuitry; image sensors and graphics processors; and multi-format, multiplexed audio/video decoding receiver circuitry. He has also litigated trademark, trade secret, copyright, unfair competition, tortious interference, and contract cases.

In addition, Mr. Gill is 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, big data/analytics, data security/encryption, social media, software/firmware, and mechanical and medical devices.

Mr. Gill also provides strategic IP counseling, due diligence, and analysis, in connection with corporate transactions and acquisitions, technology licensing, patentability, freedom-to-operate, and patent portfolio landscaping.

While a law student, 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 was a microwave and radio-frequency design engineer at Northrop Grumman, where he designed microwave integrated circuits and systems for aircraft and satellite communications and for counter-improvised-explosive-device-warfare technologies. Before that, he was a radio-frequency integrated-circuit design engineer at NextWave Wireless, a San Diego semiconductor company that developed chip-sets and wireless technology for WiMAX and 4G LTE.
