Patent Appeals

Mintz Levin attorneys regularly argue patent appeals at the Court of Appeals for the Federal Circuit (CAFC), and related matters in other federal and state appeals venues. We have handled appeals of cases litigated by our firm, and appeals of cases litigated at the District Court and USPTO by other firms. We are adept practitioners who have a strong record of success in appeals of complex IP and technology disputes. Our attorneys have successfully upheld or overturned adverse decisions on behalf of clients operating in the life sciences and in high technology.  

An increasing number of cases are being heard by the Federal Circuit, including those triggered by Inter Partes Review decisions from the Patent Trial and Appeal Board (PTAB). Our team has been successful at the court where others have not, and we intend to continue to prevail. The firm's most recent CAFC case resulted in the court's first full reversal of an adverse PTAB decision against a patent owner (our client, Straight Path).

Case Study: Mintz Levin Prevails for NextGen at Federal Circuit

In the Court of Appeals for the Federal Circuit, Mintz Levin successfully defended our client NextGen in an appeal of a 2016 Eastern District of Texas ruling that a medical records patent asserted against NextGen and others is unpatentable under the US Supreme Court’s Alice decision, which bars patents on computer-implemented abstract ideas.

The suit claimed that NextGen’s Patient Portal program infringed on a record management systems patent held by Preservation Wellness. In its decision granting NextGen’s motion to dismiss, argued by Mintz Levin attorney Michael Newman, the Eastern District of Texas held that the Preservation Wellness patent covered only the basic concept of a medical records system, and was thus not patent-eligible under Alice.

Michael T. Renaud, Division Head for the firm’s Intellectual Property Practice, argued for NextGen and on behalf of other defendants at the Federal Circuit on April 7, 2017, and the Court handed down its ruling on April 12. The Court’s speedy ruling affirming the Eastern District of Texas decision vindicates NextGen’s position that patents directed to longstanding methods of organizing human activity are unpatentable. It also suggests that the Court has provided sufficient clarity on Section 101 jurisprudence in the wake of Alice. Intellectual property attorneys Newman, James Wodarski and Sandra Badin worked with Renaud to secure the CAFC ruling in NextGen’s favor. The firm’s Intellectual Property Practice has achieved a number of victories for clients in patent cases before the Federal Circuit.

Case Study: Victory at CAFC — PTAB Decision Reversed and Remanded

Straight Path IP Group came to us after another firm handled an inter partes review before the Patent Trial and Appeal Board in which the Board cancelled each of the challenged claims of Straight Path’s US Patent No. 6,108,704. Our team developed the appellate strategy, drafted the briefs, and argued the appeal before the Federal Circuit. The argument focused on the construction of two claim terms.  In an opinion issued on November 25, 2015, the Federal Circuit reversed and remanded the Board’s decision cancelling our client’s claims. See Straight Path IP Group, Inc. v. Sipnet EU S.R.O, No. 15-1212, (Fed. Cir. Nov. 25, 2015). It was the first time the Federal Circuit reversed a Board decision in its entirety, and only the second time it held that the Board erred in construing the claims of a patent.
