George has over 30 years’ experience in litigations and adversarial matters concerning all aspects of intellectual property, including patents, trade secrets, trademarks and copyrights.

George has had considerable experience in major patent litigations (jury and non-jury) involving computers, semiconductors and pharmaceuticals, with particular emphasis on computerized automatic machinery and equipment and automobile parts. His successful trial of a major patent jury case involving computerized equipment for custom designed ductwork led to the largest intellectual property judgment nationwide in that year. His role as lead defense counsel for a large group of automobile importers led to the dismissal of a much publicized case brought by an alleged inventor of intermittent windshield wipers, even though the same plaintiff had previously secured multi-million dollar verdicts against two of Detroit’s big three automobile manufacturers.

George also counsels clients in patent and other intellectual property licensing matters, and has been involved in the licensing aspects of large merger and acquisition transactions.

George has been recognized as a leading lawyer in the IAM Patent 1000 – The World’s Leading Patent Practitioners (2013), which ranked him in the top tiers in New York for both “Licensing” and “Litigation;” The International Who’s Who of Business Lawyers (2013, 2014); New York Super Lawyers (2009-2020) for Intellectual Property Litigation Law; The US Legal 500 for his work in the area of “IP – Patent Licensing and Transactional” (2014, 2015) and Patent Litigation (2015, 2016); and The Best Lawyers in America for Patent Litigation in New York (2020).

He has spoken before domestic and international bar association groups, authored brochures advising the Japanese community on patent matters and appeared on a number of panels teaching licensing and patent litigation matters to other lawyers sponsored by the Practicing Law Institute and the American Conference Institute.


Greg focuses his practice on patent and trade secret litigation.  He brings a unique skillset to each case: a solid technical background and the ability to simplify complex technical issues for judges, juries and his team.  Greg has represented clients in district court, at the Federal Circuit and at the Patent Trial and Appeal Board (“PTAB”).  His experience includes several trials and Markman and PTAB hearings.

Greg also advises clients on IP-protection strategies, and manages patent portfolios for several large corporations.  Greg’s practice has covered a diverse set of technologies, including digital imagers, medical devices, turbine engines, phase-change material (PCM) and computer systems and software.

Greg is active in Blank Rome’s pro bono partnership with The Veterans Consortium, representing veterans whose disability benefits have been denied by the Veterans Administration (“VA”).  Over the years, Greg has been successful in obtaining hundreds of thousands of dollars in retroactive disability payments for veterans who served the country honorably but who had been unable to obtain the disability benefits owed to them.

Greg attended Catholic University, Columbus School of Law in Washington, D.C., where he graduated magna cum laude in 2005 and was an editor of the law review.  Greg obtained a Bachelor of Science in electrical engineering (BSEE) from the University of Alabama in 1997, and a Master of Science in computer science in 2002 from the George Washington University.  Before becoming an attorney, Greg worked for a decade in software development and integration, building complex computer systems for customers including the Department of Defense.

Mr. Diskant has secured billions of dollars in judgments and settlements for his clients, with multiple verdicts greater than $100 million. In jury trials around the country, Mr. Diskant has successfully represented both plaintiffs and defendants. Two of his jury victories for plaintiffs were cited as major plaintiff's verdicts of the year; two of his jury wins for defendants were cited as major defendant's verdicts of the year. Most recently, in April 2021, his trial court win over U.S. Customs was affirmed, negating the imposition of up to $600 million in duties and penalties for the importation of a life-saving pharmaceutical.  As part of his active appellate practice, Mr. Diskant has handled over 70 appeals in federal circuit courts around the country and the United States and various states Supreme Courts.

Mr. Diskant’s patent practice focusses on pharmaceuticals and medical devices.  In one well-known series of cases involving coronary stents, he was lead counsel in over fifteen trials in district courts and arbitrations throughout the country.  In these cases, he eventually recovered over $3 billion for his client.  Mr. Diskant has handled over 35 cases in the Federal Circuit.
