The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a decision today in Zilkr Cloud Technologies, LLC v. Cisco Systems, Inc., vacating in part and affirming in part a Patent Trial and Appeal Board (PTAB) final written decision. The PTAB had held claims 1, 2, 6 through 8, and 12 through 14 of a patent owned by Zilkr Cloud Technologies, LLC unpatentable as obvious, and the CAFC remanded for further proceedings. The opinion was authored by Chief Judge Moore.
Yesterday, the U.S. Patent and Trademark Office (USPTO) announced that the agency had designated as informative a Patent Trial and Appeal Board (PTAB) decision in an ex parte appeal reversing an examiner’s rejection of patent claims directed to the isolation and detection of microRNA (miRNA) to determine a patient’s risk of radiation exposure for improper Markush groupings. Drawing primarily upon case law from the predecessor to the U.S. Court of Appeals to the Federal Circuit, the informative designation is notable for its alignment with recent Federal Circuit case law encouraging flexibility in Markush grouping analyses.
In 2025, a patent dispute between Chinese companies in the camera-module space drew close attention across the industry — SUNNY v. AAC [Patent Reexamination and Invalidation Department Decision No. 566288, et al.]. The case ended with 11 patents invalidated, four of them in their entirety. There was a single reason: the claims were not supported by the specification.
Following the U.S. Patent and Trademark Office’s (USPTO’s) July 2026 proposal to require third-party requesters for ex parte reexamination (EPR) to identify all real parties in interest (RPIs), the 26 comments submitted to the Office reveal a sharp divide among the patent owners, tech companies, industry associations and individuals who weighed in. The comment period closed August 21, and the commenters included 17 organizations, associations or companies and 8 individuals (a duplicate comment was submitted by the Intellectual Property Owners Association (IPO).
The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision today in Ironburg Inventions Ltd. v. Valve Corporation, reversing a district court ruling that had estopped Valve Corporation from asserting two invalidity grounds at trial. The majority opinion, authored by Judge Hughes, concluded that the district court relied on insufficient evidence to estop one ground and failed to adequately account for hindsight bias in estopping the other. Judge Stark filed a concurring opinion.
This week on IPWatchdog Unleashed, I speak with Martin Correa. Correa, who leads foresight work at the World Intellectual Property Organization (WIPO). Correa’s job is not to predict the future of IP, but to consider what futures are possible so WIPO and Member States can be better prepared for whatever eventuality does materialize. And since there is no data about the future—as he puts it—his work uses signals of change, horizon scanning and competing scenarios to expose assumptions and identify the decisions that could push the IP system in one direction or another.
Recent amendments to Federal Rule of Evidence 702 did not invent the trial judge’s gatekeeping obligation, nor did they transform economic analysis. They did, however, sharpen the focus on the burden of establishing admissibility and whether an expert has reliably applied a valid methodology to the facts. Combined with the Federal Circuit’s increasingly demanding review of patent damages opinions, the practical message is unmistakable: the economic case must be engineered from the beginning, or you will surely suffer the consequences only after it is too late.
On August 21, wikiHow, Inc. filed a complaint in the U.S. District Court for the Southern District of New York against OpenAI, Inc. and eight affiliated entities, alleging violations of the Copyright Act and the Digital Millennium Copyright Act (DMCA). The lawsuit centers on claims that OpenAI copied wikiHow’s how-to articles without authorization to train ChatGPT and to ground its outputs, then used that copied content to generate substitutes for wikiHow’s website.
U.S. companies planning to enter Nigeria typically build a careful playbook for market research, distribution, hiring, and regulatory compliance. Intellectual property is often the item furthest down that list, treated as paperwork to handle once commercial activity is already underway. That sequencing is backwards, and it is worth understanding why.
Van Hoven PC is looking for a patent prosecution professional, registered patent agent, or patent attorney, ready to own a portfolio of electrical and computer technology matters from invention disclosure through issuance. You won’t be buried in a drafting queue waiting your turn. You’ll work directly with Partners and clients, build real technical strategy, and file patents that are built to do something. This is a full-time, permanent position based in Michigan; however, remote work may be considered for the right candidate.
Patent monetization is often discussed as if the hard part begins when a patent owner makes the decision to license, sell, finance, or enforce its patent assets. That is a mistake and demonstrates a lack of understanding of the difficulties and complexities of patent monetization. By the time a patent owner is sitting across the table from a potential licensee, buyer, lender, litigation funder, or accused infringer, much of the outcome has already been fully determined. The real work begins years earlier in preparation for monetization.
The mythology surrounding the act of invention tends to concentrate on the breakthrough moment. There is a flash of insight, a sketch is made on a cocktail napkin, the prototype is assembled in a garage to prove the brilliance of the concept. Unfortunately, commercial markets are considerably less romantic. They do not reward ideas merely because they are clever, patentable or even technically superior. They reward products that work, solve a problem customers recognize, can be manufactured at an economically sustainable price and generate an acceptable return for whoever assumes the risk of bringing them to market.
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.
