Appeals, Issues, and Legal Strategy

About

Appeals require meticulous attention to detail, particularly those involving intellectual property. And they demand a thorough understanding of both the law and the facts to identify the one or two arguments with the most promise to persuade a panel of appellate jurists. Finnegan is widely known for the quality of its appellate briefs and oral advocacy. But we also understand that the appellate process often starts well before an appeal is ever filed. Our appellate attorneys are creative legal thinkers and skilled writers who work with trial teams to develop legal strategies, draft winning briefs, and properly preserve issues for appeal.

Appellate experience across European, German, UK, and U.S. venues
Our success derives not only from our vast technical expertise, but also our extensive appellate experience across European, German, UK, and U.S. courts. For example, Finnegan attorneys have briefed and argued hundreds of patent cases before the U.S. Court of Appeals for the Federal Circuit—quite possibly more than any other law firm—and approximately 40 have served as judicial law clerks to judges on the Federal Circuit or its predecessor court. Finnegan has also represented both petitioners and respondents before the U.S. Supreme Court and regularly assists amici curiae in filing briefs at both the certiorari and merits stages. Our attorneys have participated in briefing more than 50 cases, and they have argued several cases before the Court, including the landmark cases Bilski v. Kappos and Bonito Boats v. Thunder Craft Boats. Whether at these highest courts in the United States or at the Federal Court of Justice in Germany, we bring attorneys who understand what’s at stake and will develop a strategy to meet your needs.

Partners in advancing business goals and market value
Protecting and promoting innovation and market trust is a foundational tenet for Finnegan. Through maintaining a culture of service and leadership in professional bar and legal associations, we collaborate with colleagues in industry and government in promoting IP rights and high professional standards. Organizations we are involved with include American Intellectual Property Law Association (AIPLA), Federal Bar Association (FBA), Federal Circuit Bar Association (FCBA), and Intellectual Property Owners Association (IPO).

Experience

Brimer v. Department of the Navy
Secured an en banc Federal Circuit victory for a disabled veteran, overruling prior precedent that excluded current federal employees from the Veterans Employment Opportunities Act’s right-to-compete protections. The court held that federal agencies may not deny covered veterans the opportunity to compete for merit-promotion vacancies merely because they already work for the federal government, vacated the MSPB’s decision, and remanded for further proceedings.

Carrum Technologies, LLC v. BMW of North America, LLC, et al.

Obtained complete victory against Carrum on appeal of the District of Delaware’s claim construction to the Federal Circuit following Carrum’s stipulation of non-infringement under the claim construction, thereby exonerating BMW’s ACC system, first sold in 2000, against Carrum’s 2004 patents.

Eye Therapies, LLC v. Slayback Pharma, LLC

Finnegan represented Bausch & Lomb’s licensee Eye Therapies, LLC in an appeal at the U.S. Court of Appeals for the Federal Circuit from a Patent Trial and Appeal Board (PTAB) decision finding Eye Therapies’ patent directed to a low-dose brimonidine treatment for eye redness (Lumify®) to be unpatentable. In a precedential decision, the Federal Circuit agreed with Finnegan’s arguments and found that the Board had wrongly invalidated the patent based on an incorrect claim construction, vacating and remanding the case back to the PTAB. The proceeding settled shortly thereafter
