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 Monday, the United States Supreme Court Audrey-Millemann-03_webupheld the longstanding case law that prohibits a patent owner from receiving royalties after a patent has expired. In Kimble v. Marvel Entertainment, LLC (June 22, 2015) 2015 U.S. LEXIS 4067, the Court ruled in favor of Marvel, the licensee of a patent for a Spiderman web-shooting toy.

The plaintiff, Stephen Kimble, had patented the web-shooting toy. Kimble had talked to Marvel about licensing his patent, but Marvel declined to take a license. Shortly thereafter, Marvel began selling a suspiciously similar web-shooting toy.

Kimble sued Marvel for patent infringement. The parties settled. Pursuant to the settlement, Marvel bought the patent from Kimble for a lump sum and a three-percent royalty on future sells of the toys.

Marvel later filed a declaratory judgement action in the district court, seeking a judgment that Marvel could stop paying Kimble royalties when the patent expired in 2010. Marvel relied on Brulotte v. Thys Co., 379 U.S. 29 (1964), in which the Supreme Court had held that a patent owner could not receive royalty payments after the patent had expired, and that agreements that provided for post-term patent royalties were per se unlawful.Continue Reading Everything Old is New Again: Post-Expiration Patent Royalties are a Bad Idea!

A U.S. patent is “presumed” valid. Audrey-Millemann-03_webThat means a patent owner does not need to prove the patent is valid in a suit for infringement. And, as the U.S. Supreme Court just explained in Commil United States, LLC v. Cisco Systems, Inc., 2015 U.S. LEXIS 3406 (May 26, 2015), a defendant’s belief that the patent is invalid is not a defense to infringement.

Commil owned a patent that covered a method for increasing the speed of wireless networks. Commil sued Cisco for patent infringement, alleging that Cisco directly infringed the patent by making and using certain network equipment. Commil also alleged that Cisco indirectly infringed the patent by inducing infringement, that is, by selling the equipment to others and instructing them how to use the equipment, causing them to thereby infringe the patent.

At trial, the jury found that Cisco had directly infringed the patent. With respect to the claim of indirect infringement, Cisco contended that it did not have the required specific intent to induce infringement because it believed in good faith that the patent was invalid. The district court for the Eastern District of Texas ruled that Cisco’s evidence of its good faith belief was not admissible as a defense to infringement. The jury found Cisco liable to Commil and awarded Commil $63.7 million in damages.

Cisco appealed to the Federal Circuit Court of Appeals, arguing that the district court’s ruling was erroneous. The appellate court reversed the district court, holding that a good faith belief that a patent is invalid is sufficient to negate the required specific intent to induce infringement.Continue Reading Just Because You Think It’s Invalid Doesn’t Mean You Don’t Infringe!
