Legal status (as listed): Expired – Fee Related; anticipated expiration 2022-09-11
Purpose (from the supplied text): The invention "relates to apparatus and methods for sports training." Specifically, a trajectory detection, analysis and feedback system is provided "for analyzing the trajectory of an object launched by a human and providing feedback information regarding the trajectory to the human." The system aims to be non-intrusive, operable under conditions approximating actual play, simple to set up and operate, and to give "immediate and objective feedback." The background notes drawbacks of existing training devices (departure from actual playing conditions, intrusiveness, reliance on non-standard equipment, special environments, need for a second operator).
Plain-language scope (from the supplied text): The system "is capable of detecting one or more moving objects in free flight, analyzing a trajectory of each object and providing immediate feedback information to a human that has launched the object into flight." Feedback "may include one or more trajectory parameters" for self-evaluation. The source describes a "non-intrusive machine vision system" for detecting trajectories. Classifications include A63B24/0021 (tracking a path/terminating locations), A63B69/0071 (basketball training), and A63B2220/806 (video cameras). Listed prior-art keywords: trajectory, basketball, feedback information, player, parameters.
What the excerpt does not establish: It provides only background/definitions and bibliographic data—not the full claims, detailed description, or drawings. Therefore the precise claim scope, claim limitations, and the specific basketball embodiments are not verified here. It also does not establish validity, enforceability, or the accuracy of the listed assignees and dates.

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.
