Sean focuses his intellectual property practice on patent litigation, strategic IP counseling, and patent valuation.  He has experience representing clients before the International Trade Commission (ITC), Federal district courts, and the Patent Trial and Appeal Board.  Sean draws on his background in computer science and software development to advise clients across the technology sector.  His practice covers a range of technologies including microprocessors, graphics processors, RF circuitry, consumer telecommunication systems, semiconductors, parking meters, drones, software, and flocked swabs.

Sean has held multiple roles in ITC investigations and Federal district court cases where he is relied upon by trial team leaders for developing infringement, validity, and claim construction positions in cases involving global high tech companies.  Additionally, he has served as counsel and liaison in multiple inter partes review and post-grant proceedings, where he developed and coordinated validity positions for patents being simultaneously asserted in multiple jurisdictions.

Sean’s practice is complemented by years of industry experience.  Before joining Mintz, Sean was a software engineer for a defense contractor where he specialized in distributed systems designed to find radio-based targets with direction finding and geolocation techniques and with low-level hardware devices and wireless communication protocols.  Before that, for his graduate work, Sean conducted research at the University of Massachusetts at Lowell focusing on wireless sensor networks.

A Business Deal Could Kill Your Right to Challenge a Patent’s Validity

February 22, 2022 | Blog | By William Meunier, Peter Cuomo, Marguerite McConihe, Sean Casey

Last week, the Federal Circuit issued a decision holding that parties can contractually bargain away their rights to file petitions for Inter Partes Review (“IPR”) at the Patent Trial and Appeals Board (“the Board”). This precedential case is the first to hold that a forum selection clause can forfeit the right to challenge a patent’s validity by IPR. The takeaway from this case is that when entering into any type of patent related agreement, be careful to ensure that your right to file IPR petitions is not stripped away, particularly by way of a forum selection clause which is “prima facie valid and should be enforced” in the words of the Federal Circuit.

PTAB “Overlooks” Rehearing Consequences and Swings the Rehearing Door Wide Open

October 1, 2021 | Blog | By Daniel Weinger, William Meunier, Sean Casey

A recent decision by a Patent Trial and Appeal Board (PTAB) panel in Canadian Solar Inc., et al v.

When confronted with instituted IPRs, Patent Owners should identify and exploit issues that the Petition glossed over and bring those to the attention of the Board.  This will highlight for the Board important issues that the Petition failed to sufficiently address and can lead to victory for the Patent Owner.

As a Patent Owner in an instituted Inter Partes Reviews (“IPR”), one of the first and most critical tasks before you is deposing the Petitioner’s witnesses, including its experts.  But approaching an IPR deposition like a typical litigation deposition could be a big mistake.

The Federal Circuit’s recent Uniloc 2017 v. Facebook Inc. decision is a mixed bag of good and bad news for both patent owners and inter partes review petitioners.  On the plus side for patent owners (but not for petitioners), the Federal Circuit determined that the so-called “No Appeal” provision does not necessarily apply to 35 U.S.C. § 315(e)(1), and, therefore, a patent owner may still appeal a Patent Trial and Appeal Board determination that a petitioner is not estopped from maintaining an IPR under § 315(e)(1).

Supreme Court Rejects USPTO Attorney Fee Policy

December 17, 2019 | Blog | By Michael McNamara, Sean Casey

On December 11, 2019, the U.S. Supreme Court struck down the U.S. Patent and Trademark Office’s (USPTO) controversial policy of shifting attorneys’ fees in Peter v. NantKwest, Case No. 18-801. The Court ruled that the USPTO policy ran counter to the long-accepted “American Rule,” which says “[e]ach litigant pays his own attorney’s fees, win or lose, unless a statute or contract provides otherwise.”
