The Federal Circuit Court of Audrey-Millemann-03_webAppeals has established a new test for “divided” patent infringement. Direct infringement of a method patent exists when a single party performs all of the steps of the claimed method. 35 U.S.C. §271(a). Divided infringement occurs when all of the steps are not performed by a single party, but by two or more parties under circumstances such that one party is still responsible for the infringement.

The law of divided infringement has been a subject of much debate. The question is: should direct infringement be expanded so that a single party is liable for infringement of a method claim even if another party performed some of the steps of the method? Those who say “no” argue that one party cannot infringe a method patent if it does not perform all of the steps of the claimed method, and that any other interpretation is so broad that it would make infringers out of innocent parties. Those who say “yes,” however, argue that infringers can escape liability for patent infringement simply by dividing up the steps of the claimed method among two or more parties.

In its previous decision in this case, a panel at the Federal Circuit had held that a party can be liable for divided infringement if it shares a principal-agent relationship, a contract, or a joint enterprise with the other party who performs some of the steps. On appeal to the United States Supreme Court, however, the Supreme Court vacated that decision and remanded the case to the Federal Circuit, stating that the Federal Circuit’s test for divided infringement may have been too narrow.Continue Reading Divided Infringement: A Stronger Sword for Plaintiffs

Patents covering software for use in the financial industryAudrey-Millemann-03_web are increasingly being invalidated by the courts. Because of the Supreme Court’s decision in Alice Corp. v. CLS Bank International, 134 S. Ct. 2347 (2014), district courts are holding these patents invalid on the grounds that they are unpatentable abstract ideas, and the Federal Circuit Court of Appeals is affirming the district courts’ decisions.

Patents may cover one of four statutory categories of inventions: (1) machines; (2) articles of manufacture; (3) processes; and (4) compositions of matter. 35.U.S.C. §101. These types of inventions are called “patent-eligible subject matter.” The longstanding exceptions to these four categories are: natural phenomena, laws of nature, and abstract ideas. These types of inventions are called “patent-ineligible subject matter.”

In Alice Corp., the Supreme Court established a two-part test to determine the patentability of claims directed to patent-ineligible subject matter. The first step is to decide whether the claims in the patent are directed to patent ineligible subject matter, such as an abstract idea. If so, the second step is to determine whether the elements of the claim transform the abstract idea into a patent-eligible application.

Two recent cases illustrate the trend. In both cases, the claims covered software for use in the financial industry, as was true of the claims invalidated in Alice Corp.Continue Reading Federal Circuit Continues to Nix Financial Patents

In general, any appeal from a civil action involving claims of patent infringement must be made to the Federal Circuit in Washington, D.C. A recent case from the Ninth Circuit, Amity Rubberized Pen Company v. Market Quest Group, illustrates this principle as well as demonstrating the practical measures an appellate court will take to help an appeal survive.

In Amity Rubberized Pen Co., Amity held a patent for a device that dispensed both toothpicks and tablets such as breath mints. In 2006, Amity sued Market Quest Group alleging infringement of its patent and brought various other federal and state law claims. Counsel for Amity withdrew from the case during trial and the court declared a mistrial and ordered that Amity substitute in new counsel. It also awarded Market Quest its attorney’s fees and costs for the mistrial and warned Amity that it would dismiss the case if it failed to pay. Amity did not pay the fees and in 2010, the Court dismissed the case with prejudice.

Approximately three years later, in 2013, Amity filed a new lawsuit against Market Quest alleging similar claims as the previous action, including claims for patent infringement. Market Quest filed a motion to dismiss the lawsuit on the grounds of res judicata, arguing that the present actin was barred by the dismissal with prejudice of similar claims three years earlier. The District Court agreed and dismissed the 2013 lawsuit. Amity appealed this dismissal to the Ninth Circuit Court of Appeals instead of to the Federal Circuit.Continue Reading Patent Infringement and Appellate Jurisdiction

On February 5, 2015, Congressman Bob Goodlatte reintroduced the “Innovation Act”; a bill designed to implement several changes to the legal framework governing United States patent law. The law is designed to make it more difficult for non-practicing entities (also known as “patent trolls”) to maintain patent infringement lawsuits. The law appears to have significant support among both houses of Congress, and may soon become law.

If passed, the Innovation Act purportedly will create several disincentives aimed at increasing the risk faced by non-practicing entities when bringing patent infringement lawsuits. First, the Innovation Act would require non-practicing entities to meet a heightened pleading requirement. Non-practicing entities would be required to plead “with detailed specificity” how the accused products allegedly infringed their patents. Additionally, the Innovation Act contains a fee-shifting provision which would allow the court to award attorneys’ fees to the prevailing party. This provision was included in the Act to address the fact that most lawsuits brought by non-practicing entities are settled by the accused party because the defense costs and legal fees associated with defending patent infringement cases often run into the millions of dollars.

The patent laws require that the claims of a patent (which define the boundaries of what the patent owner can protect) “particularly point out and distinctly claim the subject matter … of the invention.”  35 U.S.C. §112, ¶2.  This requirement is referred to as “definiteness.”  A patent that fails to satisfy this requirement may be found to be invalid for indefiniteness.

The purpose of the definiteness requirement is to provide the public with notice of what the patent owner owns, and what would be an infringement of the patent.  Thus, the definiteness requirement serves to encourage innovation by providing certainty as to what the patent protects.

This year, the United States Supreme Court vacated a Federal Circuit Court of Appeals decision on the grounds that the Federal Circuit’s test for indefiniteness was not precise enough and would result in confusion in the district courts.  The case is Nautilus, Inc. v. Biosig Instruments, Inc., 189 L.Ed. 2d 37 (June 2, 2014).

In 2004, the patent owner, Biosig, sued Nautilus for infringement of a patent covering a heart-rate monitor used in exercise.  Biosig’s heart monitor was different from existing heart monitors in that it was more accurate because it did not measure both electrical signals from the user’s heart and from the muscles.  The Biosig heart monitor used two pairs of electrodes, one pair for each hand of the user.  Biosig alleged that Nautilus, who owned the StairMaster brand of exercise machine, used the patented heart monitor in StairMaster machines.
