Patent 8144717

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.

  • Miodrag Djurica: Employer at time of filing: Nederlandse Organisatie voor Toegepast Natuurwetenschappelijk Onderzoek TNO.

Original assignee

The original assignee of US Patent 8144717 was Nederlandse Organisatie voor Toegepast Natuurwetenschappelijk Onderzoek TNO (TNO). TNO is an independent Dutch research organization focused on applied scientific research, with a mission to create innovations that boost industrial competitiveness and societal well-being. They engage in contract research, consulting, and licensing of patents and specialized software, and also found new companies to commercialize innovations. Given their role as a research and licensing entity, it is unlikely they directly shipped a commercial product embodying the claims of this wireless communication network patent, but rather created the intellectual property for potential licensing or spin-off. TNO is currently operating.

NPE / troll-pattern signals

  1. Shell-entity transfer — Present (for K.MIZRA LLC). K.Mizra LLC explicitly describes itself as a "patent licensing company" (a non-practicing entity, or NPE) that acquires patents for monetization through licensing and litigation.
  2. Known asserter in the chain — Present. K.Mizra LLC is the current assignee and is widely recognized as an active patent asserter, with numerous litigations in the US and Europe. Unified Patents and RPX, which track NPE activity, report on K.Mizra's assertions.
  3. Repeat correspondent across the chain — Unclear. This information could not be obtained without access to the USPTO Assignment Center's full records for reel/frame and correspondent details.
  4. Cascading transfers — Present. There were two consecutive assignments within approximately 5.5 months in 2020: from TNO to DATASERVE TECHNOLOGIES LLC on 2020-03-05, and then from DATASERVE TECHNOLOGIES LLC to K.MIZRA LLC on 2020-08-21.
  5. Pre-litigation transfer — Not present. The transfer to K.MIZRA LLC occurred on 2020-08-21. The first identified infringement suit specifically naming US8144717 was filed in March 2026, which is more than six months after the assignment.
  6. Bankruptcy fire-sale — Not present. There is no indication of any assignor in the chain undergoing bankruptcy proceedings related to these transfers.
  7. Privateering — Unclear. While K.Mizra LLC acquires patents from various sources, including research institutes like TNO, there is no explicit evidence or public reporting suggesting TNO is funding K.Mizra to assert this patent on its behalf against specific competitors.
  8. Defensive aggregator (anti-NPE) — Not present. The chain terminates with K.Mizra LLC, an NPE, not a defensive aggregator.

Verdict

NPE — high confidence

The patent exhibits clear patterns consistent with non-practicing entity (NPE) assertion. K.Mizra LLC, a self-identified "patent licensing company" and known high-frequency asserter, is the current owner. This is reinforced by the cascading transfers in 2020, with the patent moving from a research organization through an intermediate entity to K.Mizra LLC in a span of less than six months.
