Assignment history

Inventors

• Viswa Nath Sharma: While not explicitly stated in the patent text for US8234483, Google Patents lists Viswa Sharma N. as an inventor, along with others, on a related application (Reel/Frame 17354/0278) assigned to Psimast, Inc. in 2006. It is highly probable that Viswa Nath Sharma was employed by Psimast Inc. at the time of the underlying invention or assignment, given that patents are typically assigned from inventors to their employers.

Original assignee

Psimast Inc. was the original assignee. The patent does not indicate whether Psimast Inc. shipped a product embodying the claims, nor does it explicitly state their primary line of business or current status. However, the current assignee is Edgecomm LLC.

NPE / troll-pattern signals

1. Shell-entity transfer — present.

   • 2020-05-26 Assignment to OPTICAL LICENSING LLC: The name "Optical Licensing LLC" strongly suggests a licensing-focused entity.
   • 2021-02-10 Assignment to KIRITIN, INC.: This name does not immediately suggest an operating company.
   • 2025-10-10 Assignment to EDGECOMM LLC: EdgeComm LLC is explicitly identified as having "advanced AI predictions and analytics on patent cases" and focuses on "law firms, opponents, and courts", indicating a business model centered around patent litigation and assertion, rather than product manufacturing.

2. Known asserter in the chain — present. EdgeComm LLC is the current assignee. RPX has identified EdgeComm LLC as a plaintiff in patent litigation, specifically noting complaints filed in the Western District of Texas against Marvell Semiconductor and NVIDIA in October 2025, and earlier complaints in the Eastern District of Texas in May 2025. Additionally, EdgeComm LLC has filed a case against Super Micro Computer, Inc. in May 2026. This confirms EdgeComm LLC as an active patent asserter.

3. Repeat correspondent across the chain — unclear. The provided snippets from Google Patents legal events do not include correspondent information (attorney name, firm, address) for the recorded assignments. Therefore, it is not possible to determine if there is a repeat correspondent.

4. Cascading transfers — present. The patent underwent three consecutive assignments in a relatively short period: from Psimast Inc. to Optical Licensing LLC in May 2020, then to KIRITIN, INC. in February 2021 (within 9 months), and finally to Edgecomm LLC in October 2025. This shows a pattern of transfers between entities, with at least one transfer occurring in under 24 months.

5. Pre-litigation transfer — present. The patent was assigned to Edgecomm LLC on 2025-10-10. EdgeComm LLC filed infringement suits in the Western District of Texas against Marvell Semiconductor and NVIDIA in October 2025, and previously in the Eastern District of Texas in May 2025. This indicates that the assignment to Edgecomm LLC occurred very close to or concurrently with the initiation of litigation, strongly suggesting the transfer was arranged to enable assertion.

6. Bankruptcy fire-sale — not present. There is no information to suggest any of the assignors or assignees have filed for bankruptcy.

7. Privateering — unclear. While the patent has been transferred to a known NPE, there is no explicit information in the provided snippets (such as SEC filings or specific news coverage) to indicate that an operating company transferred the patent to Edgecomm LLC to assert on its behalf against competitors.

8. Defensive aggregator (anti-NPE) — not present. The chain terminates with Edgecomm LLC, which is an active patent asserter, not a defensive aggregator.

Verdict

NPE — high confidence

This verdict is justified by the presence of several strong signals. Edgecomm LLC, the current assignee, is a known patent asserter, as evidenced by multiple infringement suits filed in 2025 and 2026 shortly after acquiring the patent. The assignment chain also exhibits cascading transfers between entities with names suggesting a licensing-only focus (Optical Licensing LLC, KIRITIN, INC.) before reaching Edgecomm LLC. The pre-litigation transfer to Edgecomm LLC in October 2025, closely preceding or coinciding with new infringement filings, further reinforces this conclusion.
