Compiled from the public trademark register as of April 1, 2026.
In the last week of March 2026 Amazon Technologies, Inc. filed PETRA directly at four trademark offices in days, with goods text describing an artificial-intelligence virtual assistant and chatbot for streaming-media devices. As of April 1, 2026 Signa found no public Amazon reference to a "Petra" assistant, which puts the filing in the small bucket that reads as a strategic product rather than a routine defensive park.
PETRA is a word mark, meaning it protects the name itself in standard characters, independent of any logo or styling. The filing shape is what makes it interesting. It went in at the USPTO (application 99729283), the EUIPO (019338950), and the Canadian Intellectual Property Office (2465571) on March 27, 2026, then at IP Australia (2640287) on March 30. There is no Madrid base: four direct national and regional applications, all filed in-house within days of each other. That is the resourcing signature companies use for something they intend to ship, not for a name they are quietly shelving.
The applications sit in Nice classes 9, 38, and 42. Nice classes are the international system for sorting goods and services: class 9 covers software, class 38 covers messaging and transmission, and class 42 covers software-as-a-service. The class 9 text claims downloadable chatbot software and an AI-based virtual assistant for documentation, development, and integration support around streaming-media devices, smart televisions, and connected home-entertainment systems. Class 38 covers the messaging layer for that support, and class 42 covers the hosted version.
As of April 1, 2026 all four applications were filed and awaiting examination, with no examiner action yet at any office. The product read, that this is an AI support assistant for Fire TV or similar streaming hardware, is an inference from the goods language, not anything Amazon has said publicly.
PETRA did not arrive alone. March produced a run of AI-named filings from companies you would not expect to see naming AI products, several on the register before any public reference existed. That pre-announcement gap is what a trademark monitoring feed catches.
AI SLOPSTOPPER (DoubleVerify, Inc.). The ad-measurement firm filed AI SLOPSTOPPER as a word mark at the USPTO (application 99726735) on March 26, 2026, in class 42, for non-downloadable software that measures media quality and detects AI-generated content across digital and social media. As of April 1, 2026 the mark was filed and not yet examined, with no public DoubleVerify reference to it; it surfaced publicly only later. A recognizable adtech name staking out an "AI slop" detector shows how fast the naming around AI-generated content is forming.
SPECTRAL FOUNDATION MODEL (Lockheed Martin Corporation). Lockheed filed SPECTRAL FOUNDATION MODEL as a word mark at the USPTO (application 99705070) on March 16, 2026, in class 42, for non-downloadable AI software that ingests, processes, models, and interprets spectral data from energy-detecting sensors. It was filed and unexamined as of April 1, 2026, with no public product reference found. The hook is the vocabulary: "foundation model" is AI-lab language, and here a defense contractor is putting it on the register. As a labelled inference, the goods text points at a sensor-data or surveillance-oriented AI model, which Lockheed has not announced.
The register catching up to announced launches
Not every March filing was a scoop. Several large companies filed marks for products they had already shown. The contrast with PETRA is the point: announce first, and the register offers almost no lead time.
Apple MACBOOK NEO. Apple filed MACBOOK NEO as a word mark in class 9 at the USPTO (application 99682092) on March 4, 2026, and at the EUIPO (019328950) on March 11, plus a Madrid international registration designating additional offices. Apple announced the product the same day it filed in the US, at a New York event on March 4, 2026. The two direct applications were not at the same stage as of April 1, 2026: the USPTO application was still filed and unexamined, while the EUIPO application had already been published for opposition (the stage where the office advertises the mark and third parties can object), in Bulletin 2026/056 on March 24, with the opposition window open from March 25. File-and-announce on the same day means the register lead time was effectively zero.
Apple STUDIO DISPLAY XDR. Apple filed STUDIO DISPLAY XDR as a word mark in class 9 at the USPTO (application 99680522) on March 3, 2026, plus a Madrid international registration designating additional offices, and announced it during the same March 2026 product run. Filed and unexamined as of April 1, 2026. It is the announced-first mirror image of the quiet PETRA filing.
Amazon's CES television cluster. Behind a launch Amazon had already made at CES in early January 2026, the company filed for EMBER (USPTO 99718964), ARTLINE (USPTO 99718958), and OMNISENSE (USPTO 99701147) across March. This is register protection trailing a public launch, not new product news.
Name Clashes
TRUMP 250 (DTTM Operations, LLC). The Trump Organization's IP-holding company filed TRUMP 250 in three forms at the USPTO on March 6, 2026: a word mark (application 99687654), a figurative logo mark (99687730), and a combined mark (99687949). The applications span Nice classes 16, 18, 21, 25, and 28, covering stickers, carrying bags, drinkware, clothing, and sporting balls. They were filed on an intent-to-use basis, meaning the applicant filed before using the mark in commerce, on a stated bona fide intent to use it. As of April 1, 2026 all three were filed and unexamined. This was not a quiet filing: the applications were reported on March 9, 2026 by Gerben Law and the Washington Times, ahead of the country's 250th-anniversary year. Register facts only here.
Stat of the Month
The AI-naming wave widened in March. Counting direct applications only, applications containing "AI" in class 9 reached 183 against 120 in February, up 52 percent. In class 42 the figure was 354 against 245, up 44 percent. The narrower agent vocabulary did not follow: "agent" in class 42 came in at 28 against 34, and "agentic" across classes 9 and 42 was 21 against 17, roughly flat. Read this as a pattern, not a precise population: substring matching inflates the totals and the volume is dominated by small filers. The broad "AI" label keeps widening even as the agent vocabulary stalls. For how filings sort into these Nice class buckets, see the explainer.
On the Watch List
- PETRA (Amazon Technologies, Inc.). Watch all four direct applications for a first examination action and for any public Amazon reference tying the name to a product.
- AI SLOPSTOPPER (DoubleVerify) and SPECTRAL FOUNDATION MODEL (Lockheed Martin). Watch for examination and for a public launch connecting the register name to a shipping product.
- MRBEAST SOCIAL (Beast Holdings, LLC). Filed at the USPTO (application 99685457) on March 5, 2026, in class 35, with goods describing brand-management and social-media consulting rather than a social network. Filed and unexamined as of April 1, 2026, and distinct from the 2025 "MrBeast Financial" filing. Company-owned, so register facts only.
- TRUMP 250 (DTTM Operations). Watch all three applications through examination toward the semiquincentennial.
Signa surfaces filings like these from the global register, often before they are announced, so you can see a competitor's next product, or your own name clash in a clearance search, while it is still just an application number.
