Patent Overview — US 7,366,468 B2
Title: Wireless communication apparatus capable of wireless communication with public wireless network and wireless communication apparatus, and image communication apparatus capable of wireless communication with wireless communication apparatus
Assignee/Original Assignee: Canon Inc. / Canon Kabushiki Kaisha. Inventor: Shigeo Yoshida. Application No.: US 09/945,802. Priority date: 2000-09-12. Filing date: 2001-09-05. Publication date: 2008-04-29. Legal status listed: Expired – Fee Related (adjusted expiration 2023-04-01).
Purpose (from the excerpt): The invention "relates to a wireless communication apparatus capable of wireless communication with a public wireless network and wireless communication with an image communication apparatus, and an image communication apparatus capable of wireless communication with a wireless communication apparatus." It addresses two stated drawbacks of prior arrangements: a digital camera plus personal computer configuration "cannot be immediately transmitted," and an integrated digital camera/portable wireless apparatus suffers "poor portability."
Stated objects: provide an image communication apparatus capable of immediately transmitting a taken image and excellent in portability; improve operability of an image input device for immediate transmission; enable transmission of an image matching the recipient and of a suitable image to the recipient; and enable immediate transmission "with a specified addressee only."
Plain-language scope: A system pairing an image input unit (camera) with a portable communication unit that communicates both with a public wireless network and with the image input unit. The excerpt also describes a printer apparatus that wirelessly receives an inquiry signal sent to search surrounding devices and transmits a response signal; the response signal can indicate that the printer is pre-registered in the wireless communication apparatus and whether it is printing, and no response is sent while printing. Embodiments cover image transmission/reception data flows and flow charts (FIGS. 1–17).

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.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
Extensions
Patent term adjustments, term extensions, continuations, divisionals, family members, and expiration dates.
Derivative works
Defensive disclosure: derivative variations of each claim designed to render future incremental improvements obvious or non-novel.
