US 9523826

US Patent 9523826, titled "Pluggable optical transceiver module," was issued to Applied Optoelectronics Inc. The inventors are Chao-Hung Tsai, Chien-Te Lin, and Che-Shou Yeh. The patent was filed on October 2, 2014, and issued on December 20, 2016.

Abstract:
The patent describes a pluggable optical transceiver module designed to be inserted into a plugging slot. It comprises a main body with two opposite side surfaces and two sliding slots. A sliding component, featuring a linkage arm and two extending arms, is positioned such that the main body resides between the extending arms. Each extending arm includes a second fastening part. The extending arms are configured to slide within the two sliding slots between a fastening position and a releasing position. In the fastening position, two first fastening parts (from the socket) are secured to the module's two second fastening parts. When in the releasing position, the module's two second fastening parts press the socket's first fastening parts farther apart, facilitating release.

Independent Claims Overview:

• Claim 1: This claim defines a pluggable optical transceiver module for insertion into a socket's plugging slot, where the socket includes two elastic first fastening parts. The module features a main body with two side surfaces and two sliding slots, designed for insertion into the plugging slot. The main body also incorporates at least one limiting space with first and second limiting surfaces. A sliding component, which includes a linkage arm and two extending arms, encloses the main body, with the extending arms sliding within the main body's slots. Each extending arm has a second fastening part and a limited part that moves within the limiting space. The sliding component can be in a fastening position, where the module's second fastening parts engage the socket's first fastening parts, or a releasing position, where the module's second fastening parts push the socket's first fastening parts apart for release. An elastic component is situated within the limiting space, between the first limiting surface and the limited part, and is covered by an extending arm, ensuring it is contained by both the main body and the sliding component.

• Claim 7: This independent claim describes a pluggable optical transceiver module with a main body composed of a connected head part and an inserted part. The main body has two opposing side surfaces and two sliding slots located on these surfaces, extending from the head part to the inserted part. Similar to Claim 1, it includes at least one limiting space, with two bottom surfaces forming the sliding slots that are parallel to the side surfaces. A sliding component, with a linkage arm connecting two extending arms, also encloses the main body. Each extending arm has a second fastening part and a limited part that moves within the limiting space. The extending arms can slide relative to the slots to a fastening position (farther from the head part) and a releasing position (closer to the head part). An elastic component is positioned within the limiting space, between a first limiting surface (closer to the head part) and the limited part, and is covered by an extending arm, thereby being confined by the main body and the sliding component.

Litigation:
The patent US9523826B2 is currently involved in several litigation proceedings. This includes a case filed in the Court of Appeals for the Federal Circuit (CAFC), identified as case 26-101. Additionally, there are two PTAB cases: IPR2026-00093 and IPR2025-00433, both of which were not instituted due to procedural reasons.
