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 encompasses patent, IP, and other litigation; post-grant proceedings before the Patent Trial and Appeal Board; strategic IP portfolio development and counseling, including with respect to patent preparation and prosecution; technology licensing; and transactional matters.  He draws heavily on his industry experience and education in electrical engineering to solve complex problems spanning diverse legal, technical, and business disciplines.

Mr. Gill’s IP practice emphasizes patent infringement and FRAND/standard-essential-patent litigation.  He also litigates trademark, trade secret, copyright, unfair competition, and contract cases.  His experience includes pre-filing investigation, motion practice and fact/expert discovery, infringement and invalidity contentions, claim construction, trial preparation and 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; receiver architecture and circuitry; GPS and location services; control programs for wireless devices; and online exchanges.

In addition, Mr. Gill is a registered patent attorney.  He represents clients in post-grant proceedings before the PTAB, including Inter Partes Reviews, and he drafts and prosecutes patent applications in a variety of high-tech fields.  In this regard, he deals in such technologies as telecommunications and wireless, analog and RF circuits and systems, Bluetooth, semiconductors, MEMs, communication networks, big data and analytics, data security and encryption, social media, computing, magnetic recording media, mechanical and medical devices, and payment networks.  He also provides strategic 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 drafted and prosecuted patent applications for a Fortune 50 high-tech client when he worked at a patent boutique.  He also 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.
