The final registered version of the same pillow invention after patent examination, granted in October 2023. The registered patent consolidates several structural features into a more detailed main claim—including thoracic support and the different slopes toward the neck and lower back—while reducing the final set to three claims. The result is a more specifically defined and legally granted version of the original pillow design, emphasizing how its shape distributes support along the thoracic spine and encourages spinal and shoulder relaxation.
