Assignment history

Inventors

• James J. Fallon (Realtime Data LLC)

Original assignee

The original assignee, Realtime Data LLC, is a non-practicing entity (NPE) whose primary line of business appears to be patent licensing and assertion. Information on whether they shipped a product embodying the claims is not readily available through public patent records or general web searches. Realtime Data LLC is currently operating as a patent assertion entity, evidenced by the extensive litigation history of this patent.

NPE / troll-pattern signals

1. Shell-entity transfer — present. Realtime Data LLC's description as an "inventor-owned research and development company with technology and intellectual property in the fields of data compression and acceleration since 1998" that licenses its patent portfolio and has filed "dozens of infringement actions" suggests it operates as a licensing-only entity rather than a product-shipping company. The extensive litigation history further supports its role as a patent assertion entity.
2. Known asserter in the chain — present. Realtime Data LLC is identified in multiple sources as a prolific patent assertion entity (PAE) or NPE. The Stanford NPE Litigation Database also lists Realtime Data LLC.
3. Repeat correspondent across the chain — unclear. Only one assignment record is available from the USPTO Assignment Center, which prevents identification of recurrence of a correspondent.
4. Cascading transfers — not present. Only one assignment record is available.
5. Pre-litigation transfer — unclear. The initial assignment from the inventor to Realtime Data LLC occurred on the same day the application was filed (2014-09-24). Without a comprehensive record of subsequent transfers and the exact dates of the first infringement suits specifically naming this patent, it's unclear if any later transfers were pre-litigation. However, Realtime Data LLC's general practice involves extensive litigation, making such a transfer likely if additional assignments were to occur.
6. Bankruptcy fire-sale — not present. No evidence of bankruptcy proceedings for James J. Fallon or Realtime Data LLC was found.
7. Privateering — unclear. While Realtime Data LLC is a known NPE, there is no explicit information in the provided context or search results indicating a transfer from an operating company to Realtime Data LLC for the purpose of asserting patents on the operating company's behalf.
8. Defensive aggregator (anti-NPE) — not present. The patent is currently held by Realtime Data LLC, a known NPE, and has not been transferred to a defensive aggregator.

Verdict

NPE — high confidence. Realtime Data LLC is explicitly identified as a prolific patent assertion entity (NPE) in multiple sources and in the Stanford NPE Litigation Database. The extensive litigation history associated with this patent, with dozens of infringement actions filed by Realtime Data LLC, provides strong evidence of an NPE pattern. The sole assignment record found shows the inventor assigning the patent to Realtime Data LLC on the filing date.
