Packet Intelligence, LLC has filed a combined request for rehearing and rehearing en banc with the U.S. Court of Appeals for the Federal Circuit, asking the Court to review a July 2020 panel decision relating to its interpretation of the patent marking statute, 35 U.S.C. §287(a). In that case,  Packet Intelligence, LLC v. NetScout Systems, Inc., the panel reversed a pre-suit damages award for Packet Intelligence on the ground that NetScout was entitled to judgment as a matter of law that it was not liable for pre-suit damages based on intervening case law in Arctic Cat Inc. v. Bombardier Recreational Prods. Inc.

As an in-house IP attorney, you may take comfort in knowing that your patent marking program is thorough, well-established, and properly executed. You have standardized procedures to determine which patents cover which products. You monitor product release dates to ensure appropriate marking. You have set up a “virtual marking” website to take advantage of this form of marking established by the America Invents Act (AIA). You regularly update the virtual marking website to remove expired patents and add newly granted patents. Your patent marking program is a well-oiled machine. But what about your licensees’ patent marking programs? Do you know anything about your licensees’ patent marking programs? Do you even care about your licensees’ patent marking programs? Well, you should, and the Federal Circuit recently provided another opinion to remind patent licensors that a licensee’s failure to mark can be costly.

Rembrandt sued Samsung for patent infringement in the Eastern District of Texas and convinced a jury that Samsung infringed its two asserted patents, awarding $15.7 million in damages. Samsung appealed claim construction, denial of JMOL of obviousness, a Daubert motion on a damages expert, and the refusal to limit damages. The Federal Circuit agreed with the district court’s claim construction and its denial of Samsung’s JMOL motions, affirming those decisions… The Federal Circuit vacated because allowing Rembrandt to “avoid the consequence of its failure to mark undermines the marking statute’s public notice function.” The Federal Circuit remanded to the district court to properly limit damages, and also remanded the question of whether the marking statute applies on a patent-by-patent or claim-by-claim basis because the parties had not squarely addressed the issue during the present appeal.

Many defendants to patent troll suits have never heard of the patent owner or its patent(s), and will have never received notice of infringement until service of the lawsuit. Typically patent trolls have no product to mark, since they are non-manufacturing entities. In that situation, the patent troll must take reasonable steps to ensure that its licensees mark their licensed products – if it has licensees. If a patent troll plaintiff has not required its licensees to mark, the defendant may be able to defeat past damage claims without spending thousands in legal fees mounting a defense on the merits to an infringement claim. This, at the very least, minimizes potential exposure to a patent infringement defendant.
