En Banc Federal Circuit Reaffirms Laches as Defense to Patent Infringement Damages

The en banc US Court of Appeals for the Federal Circuit issued its opinion today in SCA Hygiene Products Aktiebolag, et al. v. First Quality Baby Products, LLC, et al., Case No. 2013-1564. In a 6-5 decision, the court reaffirmed that laches is a defense to a suit for damages for patent infringement. In reaching this decision, the Federal Circuit distinguished Petrella v. Metro-Goldwyn-Mayer, Inc., 134 S. Ct. 1962 (2014), in which the US Supreme Court held that laches is not a defense to a suit for damages under the Copyright Act.

Background

SCA Hygiene Products owns U.S. Patent No. 6,375,646 (the ‘646 patent), which relates to certain adult incontinence products. In October 2003, SCA Hygiene sent a letter to First Quality Baby Products suggesting that First Quality’s products infringe the ‘646 patent. First Quality responded in writing a month later and advised SCA Hygiene that its research indicated that there was a prior patent, U.S. Patent No. 5,415,649, that invalidated the ‘646 patent. The two companies corresponded for several more months about other products and patents, but had no further discussion regarding the ‘646 patent.

In July 2004, SCA Hygiene filed an ex parte reexamination request for the ‘646 patent. It did not advise First Quality of this action. In March 2007, the PTO confirmed the patentability of all 28 of the original claims of the ‘646 patent as well as several new claims.

Meanwhile, starting in 2006, First Quality began expanding its line of adult incontinence products. Its expansion continued for several years, with an investment of more than $10 million.

In August 2010, SCA Hygiene filed an infringement suit against First Quality. SCA Hygiene claimed that during the three-year period –– from the conclusion of the reexamination to the filing of suit –– it was implementing new business management structures, evaluating outside counsel and examining potentially infringing products on the market.

A total of six years and nine months passed from the time SCA Hygiene first notified First Quality of a potential infringement to the time SCA Hygiene filed suit. First Quality filed a motion for summary judgment on several grounds, including laches. The district court granted the laches motion, and the Federal Circuit affirmed. The Federal Circuit then granted SCA Hygiene’s petition for rehearing en banc to determine whether, and to what extent, laches remains a defense in a patent infringement action in light of the Supreme Court’s decision in Petrella v. Metro-Goldwyn-Mayer, Inc., 134 S.Ct. 1962 (2014).

The results are in: attorneys are filing more employment law cases in court.  Indeed, year-end reporting from legal databases like LexMachina confirm that the pace of filing new employment discrimination cases reached its highest level in 2025, surpassing 20,000 new filings nationwide.  Though overtime and minimum wage lawsuits under the Fair Labor Standards Act (FLSA) have continued to decline since 2015, discrimination cases under laws like Title VII of the Civil Rights Act of 1964 and the Americans with Disabilities Act are on the rise.

A recent federal court decision determined that documents created by a criminal defendant using AI and subsequently shared with legal counsel were not shielded by attorney-client privilege or the work product doctrine. In USA v. Heppner, Judge Jed S. Rakoff of the U.S. District Court for the Southern District of New York compelled the disclosure of 31 documents created with Anthropic’s Claude. This order was issued despite the defendant including information from counsel in the AI tool’s input and later providing the resulting outputs to his attorneys. The ruling offers early judicial perspective on privilege concerns involving AI-generated materials, an area where case law remains sparse.
