Patentees should implement an effective patent marking program to maximize the recovery of damages resulting from patent infringement. However, in view of recent U.S. District Court and Federal Circuit decisions, such patent marking programs must be periodically reviewed to guard against false marking.
Federal law specifies that patentees give notice to the public that a patented article be “marked” by affixing to the article the word “patent,” or its abbreviation, “pat.,” followed by the relevant patent number. 35 U.S.C. § 287. Failure to mark the patented article precludes the recovery of infringement damages until notice is given to the infringer. Id. If marking the patented article itself is impractical, then the patentee should mark the packaging of the patented article. Id. The statute does not apply to patented methods.
When the claims of only a single patent cover the patented article, the marking of that patented article, or its packaging, is straightforward. However, when the claims of several patents cover the patented article, compliance with the patent marking statute is more difficult, because the patentee must determine which patent numbers should be affixed to the patented article.
False Patent Marking
False patent marking has been traditionally asserted when the patent marker is alleged to mark articles, either with an incorrect patent number or with a patent number that does not cover the article, and with the intent to deceive the public. Such false patent marking, prohibited under 35 U.S.C. § 292(a), is believed to "wrongfully quell competition...thereby causing harm to the [United States] economy." Stauffer v. Brooks Bros., Inc., 619 F.3d 1321, 1324 (Fed. Cir. 2010). As provided under the statute, false marking is punishable by a fine of not more than $500 for every such offense. 35 U.S.C. § 292(a) Section (b) of this statute provides for a qui tam suit in which anyone may sue for the penalty and share in half of any judgment with the federal government. 35 U.S.C. § 292(b).
Recently, the false patent marking statute has been asserted against patentees that have failed to remove expired patent numbers from their patented articles. Patentees have attempted to defend against these lawsuits by claiming that just “anyone,” without a false marking injury, lacks standing. However, the Federal Circuit has recently confirmed that the statute provides broad standing for anyone to bring suit on behalf of the federal government. Brooks Bros., 619 F.3d at 1325 (emphasis added). Patentees have also unsuccessfully attempted to lessen the impact of any potential damages by arguing that the $500 fine is per decision and not per article. The Forest Group, Inc. v. Bon Tool Co., 590 F.3d 1295, 1304 (Fed. Cir. 2009) (holding that the fine is $500 per article).
In view of the increase in false patent marking litigation, patentees should establish steps to limit exposure to false marking lawsuits while observing the need to mark their patented articles. As a first step, patented articles should be regularly audited after marking to ensure that the marked patents have not expired or that the claims of the marked patents covering the articles have not been held invalid or been amended in post-grant proceedings to no longer cover the articles. As a second step, patentees should implement a plan for the timely removal of non-compliant patent numbers that are affixed to their articles, even if such removal is not immediate. Consultation with a patent attorney regarding proper patent marking as well as the execution of a written plan to audit marked patent numbers and timely remove non-compliant patent numbers may limit exposure to false marking litigation by creating at least some “credible evidence that [the patentee’s] purpose was not to deceive the public.” Peguignot v. Solo Cup Co., 608 F.3d 1356, 1363 (Fed. Cir. 2010).
The patent law is ever-changing, and future false marking litigation may be curtailed by a patent reform bill pending before Congress and/or by current appeals to the Federal Circuit challenging the constitutionality of the qui tam actions. Nonetheless, patentees should implement a proper patent marking program to maximize the recovery of any patent infringement damages while steering clear of any false marking.
