Michael P. Sandonato

Representative Matters

• Served as lead counsel for Canon, enforcing patents on laser printer and copier toner delivery technology against the aftermarket, before the International Trade Commission (ITC) and in district courts across the country. Michael's work has led to four General Exclusion Orders and numerous district court injunctions. In a district court case in N.D. Ga. involving a key patent on a toner bottle technology for Canon's imageRUNNER® machines, the jury, following a 10-day trial, returned a verdict for Canon on all issues, including direct infringement, indirect infringement, and willful infringement, and awarded the full measure of damages sought. The court subsequently awarded Canon enhanced damages and a permanent injunction
• Served as lead counsel for Prudential in S.D. Ohio, in a trade secret case in which Prudential was accused of wrongly acquiring and using alleged trade secrets to develop Legacy Protection Plus®, an optional death benefit rider sold with Prudential Premier® variable annuity products. Following more than three years of litigation, the court granted summary judgment in Prudential's favor, finding that no misappropriation had occurred. Also served as lead counsel in plaintiff's appeal to the Sixth Circuit, which affirmed the decision of the district court
• Served as lead counsel for Sirona Dental Systems (now Dentsply Sirona) in D. Del., enforcing six patents on CMOS imaging technology developed at NASA's Jet Propulsion Laboratory against competitors. Following a Markman order in which virtually all claim terms at issue were favorably construed and an order striking a key defense, a resolution was reached
• Served as lead counsel for Candid Care Co. in D. Del. and W.D. Tex. and before the Federal Circuit, defending against a competitor's patents on a telemedicine workflow. In the first case the Delaware Court invalidated the asserted patent under Section 101 on a motion to dismiss, which was subsequently affirmed on appeal. In the second case, the Texas Court transferred the case to Delaware, causing the plaintiff to unilaterally grant Candid a covenant not to sue to divest the Delaware court of jurisdiction
• Served as lead counsel for Canon in a set of D. Del. actions brought by Intellectual Ventures, involving more than 20 patents on various technologies, including image sensors, digital cameras, scanners, and laser drivers. In one case, after defeating two patents on summary judgment, Michael served as lead trial counsel in two back-to-back jury trials on the remaining four, with the second resulting in a verdict of non-infringement. In another, Michael defeated four patents through Markman and summary judgment proceedings, before the case as to the remaining patents was resolved, just prior to trial
• Served as lead counsel for Prudential in D.N.J., in a case in which a General Patent Corp. entity alleged infringement by Prudential-branded real estate websites. Following an order finding the asserted patent to be directed to an abstract idea under the Alice test, a resolution was reached
• Served as lead counsel for Dentsply Sirona in an E.D.N.Y. case, defending against a patent on an orthodontic bracket. Following a Markman hearing, the court determined that the patentee had disclaimed key subject matter. That ruling made it impossible for the patent owner to maintain its infringement assertions, resulting in a voluntary dismissal with prejudice
