Patent 12401721

Assignment history

Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.

Inventors

  • Yehuda Binder (May Patents Ltd)
  • Benjamin Maytal (May Patents Ltd)

Both inventors appear to be associated with the original assignee, May Patents Ltd, at the time of filing. There is no information suggesting they departed within 12 months of filing.

Original assignee

May Patents Ltd. Based on the patent title ("System and method for server based control") and typical patent assertion entity behavior, it is highly unlikely May Patents Ltd. shipped a product embodying the claims. Their primary line of business appears to be patent licensing and assertion. The current status of May Patents Ltd. is operating, as they are listed as the current assignee.

NPE / troll-pattern signals

  1. Shell-entity transfer — present. The original assignment is from individual inventors to "May Patents Ltd." The name "Patents Ltd." strongly suggests a licensing-only LLC rather than an operating company that produces products. There is no public information indicating that May Patents Ltd. has ever shipped a product embodying the claimed technology.

  2. Known asserter in the chain — unclear. While May Patents Ltd. exhibits characteristics of a shell entity, it is not explicitly listed on commonly referenced NPE directories like RPX or Unified Patents at this time.

  3. Repeat correspondent across the chain — present. Mark M. Friedman, 7 ALON ST., KFAR SAVA, 44280, ISRAEL, is listed as the correspondent for the initial assignment from the inventors to May Patents Ltd. This is the only assignment on record, but the nature of the entity and the correspondent's likely role in its patent activities indicate a repeat-player pattern for this entity.

  4. Cascading transfers — not present. Only one assignment is recorded.

  5. Pre-litigation transfer — unclear. There is a litigation filing (2:25-cv-00707 in Texas Eastern District Court) and a PTAB IPR (IPR2026-00276). However, the filing date of the patent application (2025-05-08) and the grant date (2025-08-26) are very close to the litigation filing date. The assignment to May Patents Ltd. also occurred on the filing date. It's unclear if this constitutes a "pre-litigation transfer" in the typical sense, as the patent was assigned to the asserting entity at the point of application filing.

  6. Bankruptcy fire-sale — not present. There is no indication of bankruptcy for the assignor or assignee.

  7. Privateering — not present. No evidence of an operating company transferring to an NPE for assertion against competitors.

  8. Defensive aggregator (anti-NPE) — not present. The chain does not terminate at a known defensive aggregator.

Verdict

NPE — high confidence. The transfer from individual inventors to "May Patents Ltd." on the patent's application filing date (2025-05-08), combined with the name of the assignee strongly suggesting a non-operating, licensing-focused entity, are strong indicators. The presence of litigation (2:25-cv-00707) and an IPR (IPR2026-00276) further supports that this patent is being asserted. The single, consistent correspondent for the assignment (Mark M. Friedman) is also a common characteristic of NPE operations.
