Federal Circuit Affirms ITC Finding That Apple Watch Infringes Masimo Blood Oxygen Patents

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a decision on Friday in Apple Inc. v. International Trade Commission, affirming a final determination that Apple violated Section 337 of the Tariff Act of 1930. The CAFC determined that the United States International Trade Commission (ITC) correctly concluded that Masimo Corporation and Cercacor Laboratories, Inc., proved that Apple violated Section 337 through the sale and import of certain Apple Watch models, ultimately “finding no error in the Commission’s domestic industry determination, its validity rulings, or its infringement findings.” The CAFC also held that the asserted patents were not unenforceable due to prosecution laches.

The Problem of Abusive Serial Challenges Using Reexaminations Needs to Be Addressed by the USPTO

The current U.S. Patent and Trademark Office (USPTO) leadership has made its position on serial patent challenges crystal clear. USPTO Director Squires warned that “even extremely strong patents” cannot survive repeated rounds of review. See NPRM Comments (10/16/2025)…. Once again, Director Squires and Deputy Director Stewart are right on the mark. Allowing excessive serial challenges to patents is unfair to patent owners and undermines the patent system.

Other Barks & Bites for Friday, March 20: CAFC Approves Flexible Domestic Industry Analysis at ITC; MFN Pricing Threatens $167 Trillion in Medical Innovation’s Societal Value; and UK Has No Preferred Option for AI and Copyright

This week in Other Barks & Bites: the Federal Circuit okays the U.S. International Trade Commission’s flexible analysis of the technical and economic prongs of the domestic industry requirement; the University of California tops the National Academy of Inventors list of top universities obtaining U.S. utility patents last year; the EU’s highest court rules that first requests for data access under the General Data Protection Regulation may be excessive if part of a systemic pattern of entering data claims for compensation; and more.

We Need a More Permanent Solution to Inter Partes Review Overreach

U.S. Patent and Trademark Office (USPTO) Director John Squires stated in his Senate confirmation hearing last year that “with born strong patents and robust quality marks we can reclaim America’s primacy, revitalize industry and growth, proudly export our culture, boost national security and improve our lives.” If the goal is to have “born strong patents”, we must be honest about what is born with patents and what is not. For instance, a credible mark of novelty is born with every patent—that much is clear. However, novelty is not just technical newness—it is also market impression. If novelty were only technical newness, people would own patents without their technology ever being used in the market. There would be no point to the patent system. This means that the rest of patents—their assertion power, damages recovery power, term limitation, claim bundling provision, inter partes review (IPR) fee requirement, and more—must also be part of the birth. This is how to create born strong patents.

The Supreme Court Must Revisit Prosecution Laches—And the Industry Should Speak Up

The latest chapter in the long-running saga of inventor Gil Hyatt is beginning to unfold. The current fight is over prosecution laches—and whether the doctrine even exists. In his last appeal to the Federal Circuit, Hyatt argued that prosecution laches is not available in Section 145 proceedings because it is inconsistent with the Patent Act of 1952, as confirmed by recent U.S. Supreme Court rulings in Petrella v. Metro-Goldwyn-Mayer (2014) and SCA Hygiene Products Aktiebolag v. First Quality Baby Products (2017). Whether Hyatt is correct about prosecution laches being inconsistent with the 1952 Patent Act, it is clear that the Supreme Court has unequivocally ruled in both Petrella and SCA that laches simply does not exist when there is a statutorily prescribed timeframe to act.

Patent Prosecution in the AI-Native Future: How IP Counselors Can Succeed

As discussed in my prior article, the growing adoption and sophistication of assistive AI tools for patent prosecution are paving the way for material business and career impacts, such as decreased prosecution revenue and reduced staffing over the long term. Despite these potential risks, practitioners and enterprises may experience widely differing outcomes due to their client mix, expertise, and capacity to navigate shifting winds to advantage.
