This page is the campaign hub for Arbor Systems LLC's Eastern District of Texas multi-defendant wave. Arbor is suing IoT and device companies on smart-device patents that describe cameras, wireless links, and related processors in networked gadgets. Patent sets differ by defendant, so each complaint is its own map. These are early Marshall Division filings.

Patents by defendant
Against Shiftall, Arbor asserts U.S. Patents 10,046,229 and 11,496,870. Against Teltonika, Arbor asserts U.S. Patents 10,195,513 and 9,849,364. The short-form complaints incorporate exemplary claim charts rather than listing claim numbers in the body. The patent set differs between these two defendants.
What the patents cover
U.S. Patent 10,046,229 (Smart device). Independent claim 1 requires a processor and wireless transceiver, a camera that determines a nearby object's distance, shape, or dimension, an accelerometer, and a module that records and compares motion and renders responsive video using camera and accelerometer outputs.
U.S. Patent 11,496,870 (Smart device). Independent claim 1 requires a processor, wireless transceiver, camera, and accelerometer, with code that follows motion, captures an event view, detects a viewer's head position, adjusts the viewing angle, and augments the view with a simulated object driven by sensed viewer actions.
U.S. Patent 10,195,513 (Smart device). Independent claim 1 requires a processor, sensor, transceiver, and a module that processes a blockchain smart contract. The processor stores tamperproof events on a blockchain or side chain and executes smart-contract terms, with another module forming a contract between the processor and another machine.
U.S. Patent 9,849,364 (Smart device). Independent claim 1 requires a body with a blockchain address, a processor that identifies the body on a blockchain, a wireless transceiver, a sensor that stores tamperproof events on the blockchain, and an accelerometer that stores acceleration data there.
What the lawsuits are about
These are Marshall Division smart-device / IoT portfolio cases. Shiftall is a Japan-based device company; Teltonika is a Lithuania-based IoT group. Arbor seeks damages and related relief on the charted claims for each defendant's exemplary products.
What it means
Arbor is running an East Texas multi-defendant wave on broad smart-device patents. Read each complaint for the patent set; the Shiftall and Teltonika pairs already differ.
What to watch next for the campaign
Watch whether the Marshall cases are related before one judge, answers and early motions once service is complete, and whether later defendants get the Shiftall or Teltonika patent set.
