Assignment history

Inventors

• James Wight: Likely employed by or associated with IceFyre Semiconductor, Inc. at the time of filing. IceFyre Semiconductor Inc. was a WiFi chip startup that was winding down operations in May 2005.

Original assignee

The patent lists "Individual" as the original assignee, referring to the inventor, James Wight. The first corporate entity in the chain, IceFyre Semiconductor, Inc., was a WiFi chip startup focused on single-chip modem solutions for 5-GHz wireless local area networks. IceFyre Semiconductor Inc. was reportedly winding down its operations in May 2005, which was prior to the patent's filing date of August 31, 2006. Thus, IceFyre Semiconductor Inc. did not ship a product embodying the claims under this patent's ownership. The company's current status is presumed dissolved or defunct given its reported winding down in 2005.

NPE / troll-pattern signals

1. Shell-entity transfer — Present

   • IceFyre Semiconductor, Inc. to Zarbana Digital Fund LLC: IceFyre was winding down operations in 2005, indicating it was no longer an operating entity at the time of the 2007 assignment (Reel 020478/0746). Zarbana Digital Fund LLC's name suggests an investment or fund-based business, rather than product development.
   • Zarbana Digital Fund LLC to Intellectual Ventures Assets 199 LLC: Intellectual Ventures (and its asset-holding LLCs) is widely described as a patent monetization firm and "patent troll" (Reel 065586/0328).
   • Intellectual Ventures Assets 199 LLC to Integral Wireless Technologies LLC: Integral Wireless Technologies LLC was created in Texas on September 30, 2024, and has been identified as a "Texas monetization firm" that has received patents from Intellectual Ventures and commenced litigation (Reel 065586/0329).

2. Known asserter in the chain — Present

   • Intellectual Ventures Assets 199 LLC is an entity associated with Intellectual Ventures, which is a widely recognized patent monetization firm and is often characterized as a "patent troll." (Reel 065586/0328).
   • Integral Wireless Technologies LLC is the current assignee and has filed multiple patent infringement lawsuits involving this patent. RPX identifies Integral Wireless as a "Texas monetization firm." (Reel 065586/0329).

3. Repeat correspondent across the chain — Present

   • Intellectual Ventures Management, LLC, of Wilmington, DE, is listed as the correspondent for two consecutive assignments in 2024 (Reel 065586/0328 and Reel 065586/0329).

4. Cascading transfers — Present

   • Two consecutive assignments were executed on the same day (2024-10-10) and recorded on the same day (2024-10-16): from Zarbana Digital Fund LLC to Intellectual Ventures Assets 199 LLC, and then from Intellectual Ventures Assets 199 LLC to Integral Wireless Technologies LLC (Reel 065586/0328 and Reel 065586/0329).

5. Pre-litigation transfer — Present

   • The patent was assigned to Integral Wireless Technologies LLC on October 10, 2024 (execution date) (Reel 065586/0329). Litigation involving this patent, such as the case filed in the Florida Southern District Court (0:25-cv-62546), was initiated on March 12, 2025, which is within six months of the assignment. Another case (Integral Wireless Technologies LLC v. Social Mobile) was filed on June 18, 2025.

6. Bankruptcy fire-sale — Not present

7. Privateering — Unclear

   • While RPX reports that Intellectual Ventures appears to retain an interest in the monetization of portfolios divested to firms like Integral Wireless Technologies LLC, direct evidence of an operating company's involvement on whose behalf the patent is being asserted is not explicitly stated in the provided records.

8. Defensive aggregator (anti-NPE) — Not present

Verdict

NPE — high confidence

The patent exhibits multiple strong signals consistent with NPE activity. It was transferred to Intellectual Ventures, a well-known patent monetization firm, and then to Integral Wireless Technologies LLC, identified as a "Texas monetization firm." The transfers included cascading assignments and a pre-litigation transfer, with lawsuits commencing shortly after the final assignment. The consistent use of Intellectual Ventures Management, LLC as correspondent further supports this conclusion.
