Building Business and Careers Starts with Listening | IPWatchdog Unleashed

This week on IPWatchdog Unleashed, I spoke with Fran Cruz and Marlene Valderrama. Recorded before a live audience following IPWatchdog’s Women’s IP Forum, our conversation explored how professionals build relationships that lead to business, career opportunities, and better ways of doing their jobs. Drawing on their perspectives at Juristat and Halliburton, respectively, Fran and Marlene returned to a fundamental point: earning someone’s attention begins with understanding what matters to them. That requires asking questions and actually listening.

SCOTUS Nixes Petitions Challenging CAFC Apportionment Requirements, Claim Preclusion Rulings

Yesterday, the U.S. Supreme Court issued its first major omnibus order list of the October 2026 term, denying petitions for writ of certiorari in a series of intellectual property-related cases. These denials from the nation’s highest court leave in place contested rulings over the application of apportionment principles to damages in patent and trade secret cases. Other cert denials include appeals to IP-related claims barred under res judicata, including one petition arguing for a manifest injustice exception, and yet another challenge to the Section 101 patent-eligibility inquiry developed at the Federal Circuit.

A Proposal for Addressing the AI Memory Supply Shortage

In economic theory, corporate value creation can be attributed to many factors and conflicting preferences. Prioritizing different factors produces a set of different outcomes and the outcome that is seemingly most efficient becomes the accepted norm. Sometimes however, corporate actors rely on accepted business practices which, while taken in the pursuit of the most optimal outcome, facilitate market distortions. Hit by a compute-driven demand shock and faced with resource scarcity, Samsung, SK Hynix, and Micron have opted to allocate production capacity in a way that has exacerbated an industry- wide memory card supply shortage. But to fully understand why the price of hardware components and consumer electronic devices has been steadily surging, we must first start with Nvidia.

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a decision today in O’Reilly Winship LLC v. SnapRays LLC, reversing in part, affirming in part, and vacating in part a district court’s grant of summary judgment of non-infringement on two powered cover plate patents.

Federal Circuit Upholds PTAB Enablement Finding Against Dual Herbicide-Degrading Enzyme Patent

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a decision Friday in Pioneer Hi-Bred International, Inc. v. Inari Agriculture, Inc. affirming a Patent Trial and Appeal Board (PTAB) final written decision that found claims 1 through 33 of a patent on herbicide-degrading enzymes unpatentable for lack of enablement.
