Patent Law – Alleged Infringement

John Luken served as lead appellate counsel to the appellees in a patent dispute concerning alleged infringement of two patents of directed beverage can ends and the methods of joining them to can bodies.

Ohio Willow Wood v. Alps South

John Luken served as lead appellate counsel for The Ohio Willow Wood Company (OWW), a manufacturer of prosthetic products, which came to Dinsmore after it had lost an infringement trial against a competitor, been enjoined from selling new products, held in contempt of the injunction, and ordered to pay nearly $20 million in damages to its chief competitor.

On behalf of OWW, Mr. Luken and the Dinsmore appellate team successfully obtained a stay of the contempt order from the Federal Circuit, which allowed OWW to begin selling its products again. After briefing and argument, the Federal Circuit reversed the lower court’s judgment and dismissed the complaint for lack of standing, thereby overturning the judgment against OWW. Mr. Luken also successfully opposed a petition for rehearing and rehearing en banc.

OPW Fueling Components/PISCES Underground Piping Patent Litigation and Related Cases

We are lead counsel for OPW Fueling Components and its PISCES subsidiary in numerous cases involving underground piping patents. Our victory in the initial case permitted OPW to enter into a substantial new product line. We defeated a preliminary injunction motion, obtained a very expedited discovery and trial schedule per OPW’s need for prompt resolution, and prevailed at trial before the U.S. District Court in Philadelphia over contractual and patent challenges to OPW’s right to purchase certain patents and to enter into this business. Total Containment, Inc. v. Osborne, et al., No. 96 7241 (E.D. Pa. 1997). This led to further infringement and contract litigation in which we have represented PISCES (the OPW affiliate which purchased these patents) against several infringers and licensees, which have also been resolved favorably for PISCES.

Patent Infringement Litigation

On behalf of our client, we developed and implemented cost-effective strategies for defending a patent enforcement suit.

Patent Infringement Litigation

Under Section 337 of the Tariff Act of 1930, the ITC investigates claims of unfair trade practices occurring in import trade. An increasing number of intellectual property lawsuits are tried before the ITC because ITC cases proceed faster than cases litigated in federal district courts, where most IP litigation takes place. The ITC also offers a unique set of remedies to companies engaged in patent disputes. The ITC has become a global forum for high-stakes patent cases brought by both U.S. and foreign companies intent on protecting valuable U.S. based IP rights. Dinsmore & Shohl LLP has a great deal of experience successfully representing parties in 337 investigations. For example, on behalf of our client, a $1 billion industrial machinery manufacturer, we reached successful settlements against multiple respondents importing industrial machinery from China, Germany, Italy and France.

Procter & Gamble v. Bankers Trust

We were counsel for Procter & Gamble in litigation in 1994-96 against Bankers Trust arising out of two substantial derivatives contracts entered into by P&G. The litigation raised numerous issues of first impression involving the application of contract, fraud, negligence and fiduciary duty, federal and state securities and commodities and RICO law to derivatives contracts, and led to Sixth Circuit and Supreme Court decisions on issues including the discoverability of materials relating to Federal Reserve Board examination of regulated banks and the power of District Courts to enjoin publication of materials filed under seal under protective orders. The case involved massive discovery of hundreds of thousands of pages of documents and thousands of audiotapes and computer files, and required extensive computerization for discovery management. The matter settled shortly before trial, resulting in a $165 million recovery by P&G, the largest (in absolute or percentage terms) of any such publicly reported derivatives recovery.
