The United States Patent and Trademark Office plans to issue a reexamination certificate confirming four of Apple’s claims regarding its rubber-band patent, according to FOSS Patents. The patent is one of Apple’s most famous technologies and relates to the bouncing effect in iOS when a user reaches the end of a page while scrolling. One of the claims validated by the USPTO, claim 19, was successfully used by Apple in its $1 billion victory over Samsung. The South Korea-based smartphone maker had previously attempted to invalidate the patent, however it failed to convince the patent office to uphold the ruling. The USPTO’s recent decision has been called a “huge win” for Apple.
