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.

Assignment history

Inventors

Samer U. Al-Azem: PetroHab

Original assignee

The original assignee is listed as "Individual" on the issued patent. It is unclear if "Individual" refers to the inventor, Samer U. Al-Azem, or another entity. Based on the patent's description of "enclosures usable to contain pressure, perform hot-work (e.g., welding operations), contain sparks, or isolate ignition sources, or similar functions," it is highly likely that a product embodying the claims would be related to industrial safety enclosures, particularly for hot-work environments. Samer U. Al-Azem is a frequent author on topics related to hot-work safety, welding, and pressurized enclosures for PetroHab, an entity that appears to operate in this space. However, without clear assignment records, the direct commercialization by "Individual" or their specific primary line of business and current status are undeterminable.

Verdict

Insufficient data.

While litigation is noted, the absence of assignment records prevents any conclusions regarding the nature of the assertion.
