She assists clients with the preparation and prosecution of U.S. and foreign patent applications, as well as European Supplementary Protection Certificates for pharmaceuticals; drafts legal opinions regarding infringement, validity, and freedom to operate; and conducts intellectual property due diligence studies.

Clients benefit from Deirdre’s experience involving contested matters, including patent office interferences, foreign patent oppositions, arbitration proceedings, and intellectual property litigation before federal courts in Texas, New York and California, as well as the District Court of the Hague related to issues of patent infringement and validity, trademark infringement and cancellation, intellectual property license agreements, and officer tort liability.

Deirdre received her Juris Doctor degree from Boston College Law School, where she worked for the ABA Committee on Rules of Practice and Procedure, United States Judicial Conference.

The success of her practice is fueled by the balance of her strategic biotechnology patent prosecution counseling and her general intellectual property litigation and enforcement experience. She guides clients through the development, management, and protection of intellectual property rights.

Representative Litigation Experience

• Defended several different pharmaceutical companies in several different patent infringement actions in the U.S. District Court for the District of New Jersey and elsewhere, involving pharmaceutical formulations.  We were able to negotiate favorable settlements for our client that were each reviewed without objection by Federal Trade Commission.
• Represented a Fortune 500 company in enforcement litigation of a group of its biotech patents. The case resulted in a settlement payment of more than 60% of the infringer’s gross revenue on its infringing sales, a permanent injunction, and the sending of a joint letter to the infringer’s customers urging them to make their future purchases from our client.
• Represented an international research and development company in litigation in the U.S. District Court for the Eastern District of New York, as well as a related arbitration, against a licensee of the client’s patents that involved video recorder technology. After a three-week trial, our client received a judgment that exonerated it of all alleged improprieties and vindicated its early termination of the license.
• Represented a plaintiff in successive patent jury trials in the Northern District of California involving components for printed circuit boards.  The first trial resulted in a finding of validity and infringement in the liability phase and subsequent contempt citations against the defendant for new designs.  The case settled prior to the damage phase with the defendant agreeing not to market any infringing product.  The second trial resulted in the jury finding willful infringement of a redesigned product, with increased damages and attorneys’ fees awarded by the court.
• Represented a leading developer of sports and entertainment ticketing technology in a patent infringement action against a larger industry competitor in the U.S. District Court for the District of Delaware. The technology involved an electronic ticketing system.
• Represented a leader in the entertainment promotion industry and patent owner in various actions against an industry competitor involving a patented promotional method and device in the U.S. District Courts for the Southern District of New York and District of Delaware.
• Defended a patent infringement action involving oil refinery technology in the U.S. District Court for the Southern District of Texas. After summary judgment of patent invalidity was affirmed on appeal, the patent owner paid our client a high six-figure amount toward its litigation defense costs. We also identified insurance policies which led to our client’s receiving a further mid-six figure amount toward its litigation defense costs.
• Represented numerous financial institutions and venture capital firms on providing assessment of litigations and likely results. This information was used by our clients to develop strategies for equity and debt trading, or as part of an overall due diligence assessment of “litigation health” of target companies.
• Represented a registrant in a cancellation proceeding for a service mark for vacation rentals in Italy to the general public and business entities. We were successful in securing termination and dismissal of the cancellation proceeding.
• Represented a major research-based pharmaceutical company as the senior party in a patent interference involving a human cytokine.  After the parties filed initial papers and a list of preliminary motions, we achieved a settlement that included a process for determining priority of invention. Upon determining priority, the opposing party requested judgment adverse to it.
• Represented a major medical diagnostic service provider in connection with a patent application involving a nucleic acid.  We developed a strategy that resulted in the issuance of patents on noninterfering subject matter, without the expense of an interference.
• Represented a biotechnology company as the senior party in a patent interference involving a method of treating a disease with an antibody. The opposing party conceded priority of the subject matter of the interference, and requested judgment adverse to it, after two of its noninterfering claims were removed from the interference.
• Represented a world-renowned cancer research and treatment hospital as the junior party in related patent interferences involving DNA, protein and method claims. Even though we represented the junior party, the opposing party conceded priority as to the most significant claims, resulting in the entry of judgment adverse to the opposing party on those claims.
• Representing several different branded pharmaceutical companies in litigation “war games” that allowed our clients to foresee possible strategies and tactics that a generic might use to avoid patent portfolios on very valuable brand pharmaceutical products. As a result of each of the war games, our clients were able to develop appropriate strategies under the Hatch-Waxman amendments to the Federal Food Drug Cosmetics Act and tighten their patent estates to thwart likely generic strategies even before litigation was commenced.
• Represented a major digital marketing client in a copyright dispute relating to a marketing information document.  We prepared and sent a cease-and-desist letter resulting in the infringer ceasing all infringing activity without the expense of a lawsuit.
• Represented a generic pharmaceutical company in a patent infringement matter involving a multi-billion dollar drug. Our client had valuable “first filer” status and, thus, rights to limited market exclusivity. We persuaded the brand pharmaceutical company that our client did not infringe its patents. No suit was ever filed and our client was able to go to market with very valuable 180-day exclusivity rights.
• Represented major digital marketing company in trademark dispute, sending cease-and-desist letter resulting in infringer ceasing all infringing activity without the expense of a lawsuit.
• Represented plaintiffs in the digital marketing industry in trademark action in district court, resulting in very favorable settlement agreement enjoining defendants from use of mark.
