Patent RE50606

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.

I was unable to directly fetch the full text, claims, and inventor information for US patent RE50606 through the general web search queries. This makes it challenging to populate the "Inventors" and aspects of the "Original assignee" sections with complete confidence, and to ground NPE signals directly in claim language or product embodiment.

However, I will proceed with reconstructing the full assignment record using the USPTO Patent Assignment Search, as this is the primary source for ownership information and NPE pattern detection.

Inventors

Undeterminable without access to the full patent specification.

Original assignee

Undeterminable without access to the full patent specification. Information regarding whether they shipped a product embodying the claims, their primary line of business, and their current status cannot be confidently determined without the patent's subject matter.

Assignment timeline

There are no assignment records for US patent RE50606 found on the USPTO Assignment Center (https://assignmentcenter.uspto.gov/). This indicates that the original assignee likely still holds ownership of the patent.
