Patent US6098106

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.

NPE / troll-pattern signals

  1. Shell-entity transfer

    • Present: LV PARTNERS, L.P. (assignee in 2004-07-28 / Reel 015099/0474) is a limited partnership, a common vehicle for patent holding, and its immediate onward transfer without apparent commercial activity is indicative of a shell entity.
    • Present: RPX-LV ACQUISITION LLC (assignee in 2008-11-13 / Reel 022718/0027) is an LLC with "Acquisition" in its name, suggesting a special purpose vehicle for patent holding rather than an operating company.
  2. Known asserter in the chain

    • Present: RPX CORPORATION (assignee from 2008-11-13 / Reel 022718/0024 onward) is a well-known defensive patent aggregator, which acquires patents to neutralize them from assertion by NPEs.
  3. Repeat correspondent across the chain

    • Present: STEVENS LAW GROUP appears as correspondent for two sequential assignments on 2004-07-28 (Reel 015099/0471 and 015099/0474).
    • Present: RPX CORPORATION (as correspondent) appears for multiple assignments and security agreements from 2008-11-13 (Reel 022718/0024, 022718/0027) through 2018-12-14 (Reel 043834/0071). This consistent use of an internal or closely affiliated correspondent firm across many transactions for the same patent indicates a structured, repeat-player approach to patent management.
  4. Cascading transfers

    • Present: On 2004-06-14 (executed date), the patent transferred from Digital:Convergence Corporation to Jack A Turpin, and then immediately to LV PARTNERS, L.P., both recorded on the same day (2004-07-28, Reel 015099/0471 and 015099/0474).
    • Present: On 2008-10-20 (executed date), the patent transferred from LV PARTNERS, L.P. to RPX CORPORATION, and then immediately to RPX-LV ACQUISITION LLC, both recorded on the same day (2008-11-13, Reel 022718/0024 and 022718/0027).
  5. Pre-litigation transfer

    • Not present: No litigation identified for this patent.
  6. Bankruptcy fire-sale

    • Present: The original assignee, Digital Convergence Corporation, was defunct by 2002. The transfer of the patent in 2004 (executed 2004-06-14, recorded 2004-07-28 / Reel 015099/0471) occurred after the company's failure, consistent with a fire-sale of intellectual property assets from a bankrupt or dissolved entity.
  7. Privateering

    • Unclear: While the initial transfers after the original assignee became defunct could have set up a privateering scenario, the ultimate acquisition by RPX makes this unlikely in practice for this specific patent.
  8. Defensive aggregator (anti-NPE)

    • Present: The current assignee is RPX CORPORATION, a prominent defensive patent aggregator (assignee from 2008-11-13 / Reel 022718/0024 onward).

Verdict

Defensive / non-asserting
The assignment chain, after the initial transfer from the defunct operating company, ultimately terminates at RPX Corporation (assignee from 2008-11-13 / Reel 022718/0024). RPX is a known defensive patent aggregator, whose business model is to acquire patents to prevent their assertion by non-practicing entities, effectively neutralizing them. https://assignmentcenter.uspto.gov/patents/6098106
