Title: Computer system for continuous oblique panning
Patent number: US 8,593,518 B2

Inventors: Stephen Schultz, Chris Schnaufer, Frank Giuffrida
Original/current assignee (as listed): Pictometry International Corp. (Google Patents notes listed assignees "may be inaccurate")
Priority date (listed as an assumption): 2007-02-01

Purpose (from supplied text): The disclosed invention(s) "relate to oblique images and methods for continuously panning the same." More particularly, they "use a methodology whereby separate obliquely captured images are panned in a continuous fashion."
Plain-language scope: The excerpt describes background concepts rather than the claims. It distinguishes ortho-rectified imagery and ortho-mosaics—built from nadir images captured straight down and aligned to a rectilinear grid—from oblique images, which are captured at an angle and present a more natural appearance showing the sides of objects and structures, but which are "not generally ortho-rectified." It notes that in an oblique image the horizon can lie in any direction, so screen directions (right/left corresponding to east/west versus west/east) depend on which way the camera pointed, which "can cause confusion for someone trying to navigate."
Classifications (selected): G06T3/20 (linear translation/panning); G06T11/60; G06T17/05 (geographic models); G06T7/33 (feature-based registration); H04N7/183; G06T2207/10032 (satellite or aerial image).
Litigation/administrative notices shown in the source (listed, not analyzed): PTAB case IPR2022-00735; a Utah District Court case; a Federal Circuit case (24-1763).

What the excerpt does not establish: The actual claim language, claim count, and full written description; the detailed steps of the panning methodology; the specific figures; the complete prior-art references and cited art; and any conclusions about validity, enforceability, infringement, ownership transfers, or litigation outcomes. The excerpt provided omits text, so it cannot support statements beyond the passages quoted above.

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.
