Patent summary
Title, assignee, inventors, filing/issue dates, abstract, and a plain-language overview of the claims.
US patent 9972381, titled "Memory with output control," was invented by Hakjune Oh, Hong Beom Pyeon, and Jin-Ki Kim. The application was filed on January 11, 2018, and the patent was issued on May 15, 2018. The current assignee is Mosaid Technologies Inc, with Conversant Intellectual Property Management Inc being the original assignee.
The abstract for US9972381 describes an apparatus, system, and method for controlling data transfer to an output port of a serial data link interface in a semiconductor memory. One example details a flash memory device with multiple serial data links, multiple memory banks, and control input ports that enable serial data transfer to a serial data output port. Another example outlines a flash memory device with a single serial data link, a single memory bank, a serial data input port, and a control input port for receiving output enable signals. The patent also covers flash memory devices cascaded in a daisy-chain configuration using echo signal lines for serial communication between devices.
The provided patent text does not include the numbered claims. Therefore, a plain-language overview of each independent claim cannot be provided based on the available information.
Regarding litigation, a search of CAFC 2026 dockets for US9972381 (as of April 26, 2026) reveals that there is no directly matching entry in the provided "Family has litigation" section for the year 2026 related to CAFC. However, the Google Patents information indicates that a PTAB case IPR2025-01487 was filed and is pending/instituted. Additionally, a US case was filed in the Texas Western District Court (case 1:25-cv-00436). There is also a first worldwide family litigation filed on 2005-12-30, accessible via Darts-ip. These indicate ongoing litigation at the PTAB and District Court levels, but a specific CAFC 2026 docket number for US9972381 is not explicitly listed in the provided patent information.
Summary of US9972381:
- Title: Memory with output control
- Assignee: Mosaid Technologies Inc (Current), Conversant Intellectual Property Management Inc (Original)
- Inventors: Hakjune Oh, Hong Beom Pyeon, Jin-Ki Kim
- Filing Date: 2018-01-11
- Issue Date: 2018-05-15
- Abstract: An apparatus, system, and method for controlling data transfer to an output port of a serial data link interface in a semiconductor memory is disclosed. In one example, a flash memory device may have multiple serial data links, multiple memory banks and control input ports that enable the memory device to transfer the serial data to a serial data output port of the memory device. In another example, a flash memory device may have a single serial data link, a single memory bank, a serial data input port, a control input port for receiving output enable signals. The flash memory devices may be cascaded in a daisy-chain configuration using echo signal lines to serially communicate between memory devices.
- Independent Claims Overview: The numbered claims are not present in the provided patent text. Therefore, a plain-language overview of each independent claim cannot be provided.
- CAFC 2026 Dockets: While the provided information indicates ongoing litigation at the PTAB (IPR2025-01487) and in the Texas Western District Court (1:25-cv-00436), a specific CAFC 2026 docket number for US9972381 is not explicitly listed in the provided details.
