Recent developments in ex parte Corteva Agriscience LLC (Reexamination Control 90/019,130; Patent 10,947,555 B2) clarify obviousness-type double patenting (ODP) in the context of patent families with multiple continuations and varying patent term adjustments (PTA)…. In Corteva, the Patent Trial and Appeal Board (PTAB) distinguished Cellect and extended Allergan by holding that a child patent (here, the ’555 patent) is not unpatentable for ODP if it does not expire later than the original patent in the family, including any PTA awarded to the original patent. Below is a figure from Corteva.
The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a decision today in Sansone v. United States Patent and Trademark Office, affirming the U.S. District Court for the Eastern District of Virginia’s dismissal of a pro se inventor’s lawsuit and denial of his motion for summary judgment. Stanley Sansone filed U.S. Patent Application No. 16/255,511 on January 23, 2019, seeking a patent for a wearable thermal device, but a patent examiner rejected all claims. The Patent Trial and Appeal Board (PTAB) affirmed the rejection, after which Sansone sought continued examination.
A trademark dispute between The Church of Jesus Christ of Latter-day Saints (“the Church”) and the Mormon Stories Podcast (“the Podcast”) has this week become a broader fight over the Church’s Mormon-related trademark portfolio. The Church’s complaint, filed on April 17, 2026, alleged that the Podcast’s name, branding, and use of Church imagery create a likelihood of confusion regarding whether the Podcast is actually affiliated with the Church. Meanwhile, the Podcast’s answer to the complaint and counterclaim goes further. Rather than merely denying infringement, the Podcast is now seeking cancellation of multiple Mormon-related trademarks owned by the Church..
The Supreme Court should grant certiorari in Hyatt v. Squires—a case it is scheduled to consider later this week—and finally put an end to prosecution laches in patent law. Not limit it. Not cabin it. Not send the Federal Circuit back to craft yet another multi-factor balancing test that will inevitably metastasize into a litigation weapon. The Supreme Court must end prosecution laches once and for all, period.
This week on IPWatchdog Unleashed, I spoke again with Fran Cruz, Senior Vice President of IP Solutions for Juristat. Our conversation was about a topic that should be top of mind for every patent prosecution firm, every in-house IP department, and every legal operations professional trying to make sense of the current market for patent related legal work. Where is patent prosecution work going, when does work move from firm to firm, when it does move, where is it moving, and what will firms have to do to win—or keep—the patent preparation and prosecution work?
This week on IPWatchdog Unleashed, my conversation with patent broker Louis Carbonneau centers on a fundamental breakdown in the economic engine that has historically driven innovation. While innovation itself has not disappeared, the incentive structure that once enabled a repeatable cycle—innovate, patent, monetize, reinvest—has eroded. Large market participants increasingly operate under a “use now, pay later (if ever)” model, which disproportionately disadvantages individual inventors and smaller entities. As a result, many innovators are unable to sustain continued development beyond an initial breakthrough, leading to a systemic drag on long-term innovation output. This shift is reinforced by a broader cultural normalization of “free” access to intellectual property, which has migrated from the copyright into the patent and innovation industry.
This week on IPWatchdog Unleashed, I spoke with Brent Bellows, a partner with Knowles Intellectual Property Strategies (KIPS). We discussed a variety of issues including Hatch-Waxman, Orange Book listings, paragraph IV certifications, skinny labels, generic entry, clinical trial costs, regulatory exclusivity, and the enormous financial risk associated with bringing new drugs to market. Gene and Brent explore the tension between public demand for lower drug prices and the need for durable incentives that make high-risk drug development economically viable, particularly for oncology, Alzheimer’s, Parkinson’s, antibiotic resistant bacteria, and other difficult-to-treat conditions. The episode closes with a broader innovation-policy message: patents are not a peripheral feature of drug development—they are a core operating asset that enables private-sector investment, supports breakthrough therapies, and ultimately drives the availability of future generic medicines.
The U.S. Court of Appeals for the Federal Circuit (CAFC) on Tuesday issued a decision in Enanta Pharmaceuticals, Inc. v. Pfizer Inc., affirming summary judgment that all claims of Enanta Pharmaceuticals, Inc.’s U.S. Patent 11,358,953 are invalid as anticipated. The court held that Enanta’s provisional application failed to provide adequate written description support under 35 U.S.C. Section 112 for a key chemical substituent claimed in the ‘953 patent. As a result, the patent could not claim the provisional’s earlier priority date and was anticipated by Pfizer’s prior disclosure of nirmatrelvir.
When I sat down with former USPTO Director Andrei Iancu for this week’s episode of IPWatchdog Unleashed, I expected a serious conversation about the condition of the U.S. patent system. Instead of rehashing everything that has gone wrong with the U.S. patent system from the perspective of an innovator over the last two decades, what took place was a deep and revealing conversation about whether the legal architecture that once made the United States the world’s innovation leader is still fit for purpose in an economy increasingly defined by software, artificial intelligence, data, biotechnology, and other intangible assets.
The U.S. Patent and Trademark Office (USPTO) on late Monday issued a notice designating as precedential a Sua Sponte Director Review Order of a Patent Trial and Appeal Board (PTAB) decision granting institution in three inter partes review (IPR) proceedings. The order waived the 14-day deadline for requesting Director Review of a decision to institute trial and denied institution under Hulu, LLC v. Piranha Media Distribution, LLC, IPR2024-01252, Paper 27 (Director Apr. 17, 2025).

The United States patent system is not failing because Americans have stopped inventing. It is failing because the legal and institutional architecture built to protect invention no longer operates as a coherent innovation framework. Over time, the system has become a patchwork of overlapping tribunals, inconsistent legal standards, procedural inefficiencies, and doctrinal barriers that make it harder to obtain, defend, enforce, license, and rely upon even high-quality patent rights covering innovations of extraordinary consequence. Now in the coming months we will move forward with a candid, serious, historically grounded, and focused conversation on building—not merely patching—the next American patent system.
This week on IPWatchdog Unleashed, I spoke with Lisa Jorgenson, who is Deputy Director at the World Intellectual Property Organization (WIPO). Jorgenson had just attended IPWatchdog LIVE 2026 and spoke on our final panel along with former U.S. Patent and Trademark Office (USPTO) Director David Kappos, former USPTO Director Andrei Iancu, and former International Trade Commission (ITC) Commissioner Scott Kieff. She joined me immediately following the conference at IPWatchdog Studios for a wide-ranging discussion that pulled back the curtain on an institution many in the IP community think they understand—but often do not really appreciate.
