Patent Overview: US9697643B2
Title: Systems and methods of object shape and position determination in three-dimensional (3D) space
Patent number: US9697643B2 | Application: US14/710,499 | Filed: 2015-05-12 | Granted/Published: 2017-07-04
Inventor: David S. Holz
Assignees (per the listing, which disclaims legal verification): Original assignee Leap Motion Inc; current assignees listed as Sim IP HXR LLC and LMI Liquidating Co LLC. The record also shows assignment activity involving TriplePoint Capital LLC, The Founders Fund IV LP, Haynes Beffel Wolfeld LLP, LMI Liquidating Co., LLC, and Ultrahaptics IP Two Limited.
Priority: Priority date listed as 2012-01-17, with priority claimed from US13/414,485 and US13/724,357 (the latter issued as US9070019B2). Anticipated expiration listed as 2032-03-07.
Purpose / plain-language scope: Based on the supplied excerpt, the patent concerns determining the shape and position of objects in three-dimensional space, using multiple cameras and analyzing image data. The listed "prior art keywords" — intersection, shadow, points, cameras, image — indicate the disclosed approach involves locating points via intersections and shadow information captured by cameras. Images and figures in the source suggest optical/vision-based sensing. Classifications include G06V10/25 (determining a region/volume of interest), G02B27/0172 (head-mounted optical features), and G06F3/011 (interaction with the human body, e.g., for user immersion in virtual reality), consistent with 3D motion/gesture sensing for computer input.

All PTAB activity →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.
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.
