Abstract: The patent describes a system where a video optimizer, upon receiving a request to optimize and stream a source file, uses a unique key to query a cache database. This key identifies both the original source file and the specific optimization parameters required for the user's device. The database maintains a record of optimized files stored in the local caches of a cluster of video optimizers. If a matching, pre-optimized version of the file exists on another optimizer, the database provides its location, allowing the system to avoid redundant transcoding.

Plain-Language Overview of Independent Claims

An independent claim represents the broadest definition of the invention. US Patent 9,800,633 contains three independent claims:

Claim 1: A Method
This claim outlines a method for a computer ("first video optimizer") to efficiently deliver optimized video. When a user requests a video, the request includes a unique "ID key" that specifies both the original video and the exact optimized version needed (e.g., for a specific device or network speed). The first optimizer uses this key to ask a central "cache database" if another computer ("second video optimizer") has already created and stored this specific version. If it exists, the first optimizer retrieves the already-optimized video from the second optimizer and sends it to the user, thereby saving the time and processing power needed to optimize the video from scratch.

Claim 9: A Non-transitory Computer-Readable Storage Medium
This claim protects a physical storage product, such as a server's hard drive or memory, that contains the software instructions to execute the method described in Claim 1. In essence, it covers the software that, when run on a computer, turns it into the "first video optimizer" capable of querying the cache database and serving pre-optimized videos from other optimizers.

Claim 16: A System
This claim covers the video optimizer system itself. It describes a computer system specifically configured to perform the patented method. The system is designed to receive the video request with the unique ID key, query the cache database, and if a matching file is located on a second optimizer, retrieve and stream that file to the user's device. This claim protects the hardware and software combination that forms the intelligent video caching and delivery server.

As of today's date, a search of the Court of Appeals for the Federal Circuit (CAFC) 2026 dockets did not yield any results for litigation involving US patent 9,800,633.
