Patent Overview — US8200265B2

Title: Data transfer between wireless devices

Patent number: US8200265B2 | Application: US12/644,948, filed 2009-12-22 | Priority date: 2008-12-23 | Grant/publication date: 2012-06-12 | Adjusted expiration: 2030-07-27 | Inventors: Alan G. Carlton, Alexander Reznik | Original and current assignee: InterDigital Patent Holdings, Inc.

Purpose (from the supplied "Definitions" text): Existing data transfers use applications such as electronic mail or multimedia message services (MMS), carried over technologies like General Packet Radio Service (GPRS) or Wireless Local Area Network (WLAN). File transfers remain "a cumbersome, multi-step task requiring adaptation between multiple implementations," and many technologies "involve a fragmented approach to access and manipulation of files such as attachments." These hurdles "inhibit the more regular use of file transfer schemes in spontaneous situations," so "a simplified and more intuitive approach to data transfer between devices is therefore required."

Plain-language scope: The described method controls data communication in wireless communications by detecting environment information about at least one candidate wireless transmit/receive unit (WTRU) in a local area associated with the WTRU. A user input is received via a user interface and relates to a selection of data for transfer between the WTRU and at least one candidate WTRU, and to an identified target WTRU. The user input and the candidate-WTRU information are processed; at least one target WTRU is identified from the candidate WTRUs based in part on the user input. Candidate-WTRU information "is solicited through a lower layer"; environment information is used to identify the target WTRU, and transmission instructions are generated to enable data transmission to the target WTRU. The excerpt lists figures on sending/receiving WTRUs, the wireless environment, a target discrimination algorithm, a communication method, physical layer security, a user input for transferring a file, and a user experience at sending and receiving devices.

What the excerpt does not establish: It does not set out the full claims, detailed embodiments, or the complete figure descriptions (the text is expressly truncated mid-sentence at FIG. 8), nor any figures, reference numerals, or claim language. It also states that legal status, priority, assignee, and expiration entries are assumptions, not legal conclusions. Nothing here establishes the scope of the claims as allowed.

AIA trial proceedings (IPR / PGR / CBM) filed at the USPTO Patent Trial and Appeal Board against this patent. Sourced from the USPTO Open Data Portal and refreshed every six hours; each proceeding number deep-links to the PTAB E2E docket.

No PTAB proceedings on file. This patent has not been challenged via IPR, PGR, or CBM. The absence is itself a signal — well-asserted patents eventually attract IPRs. The LLM analysis below may surface filings the ODP feed hasn’t indexed yet.

PTAB challenges

AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.

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.
